Nick, I am crazy about science. I hold a PhD in engineering. I watch tens of channels of science, of many different topics. In my opinion, your channel is the best by far if one looks for the channel with the best mixture of scientific accuracy and pedagogical efficacy. I do not know how you can explain such complex topics so well in such a short time. What you and your team achieve in every video is just outstanding.
All the teachers that tried to explain this over the years and here we go, 5 minutes later and I understand. Science Asylum should be compulsory in all schools :'D
I have to agree, Nick is amazing at making something difficult easy to understand . Perhaps Nick needs another identity/persona/channel for "grown up" concepts perhaps he already does...?
Lightning struck my truck a few years ago (well, struck a tree near it and arched through it) and fried a bunch of electronics. I can't tell you how many people questioned it saying the tires would have insulated it. My response was almost verbatim what this video said: "Really, you think lightning can travel a mile through the air, which is already a pretty decent insulator, but a few inches of rubber is going to stop it?" Explaining a farraday cage to people became a hobby for a while.
This is the first time I got a clear explanation of the migration of charged water droplet in cloud. The displacement of electrons on the ground is illustrated in such a simple animation, saving the need to explain what happen. Thanks for preventing an overload of some brain area by distributing the knowledge, The loud noise of lightning is caused by the air expanding faster than the speed of sound. It is a super-sonic boom, like the concord or fighter jet. It is a white noise, the sum of every frequencies from 20 Hz to 20 KHz... or more. A white noise in visible light is white light. An object at high temperature emit white light because the violent shaking create Doppler shifting, spreading the emission lines to span large bandwidth, covering vast frequency range.
I was wondering how lightning worked and I figured you probably didnt do a video on it, but I looked it up and here we are. Exactly the type of explanation I needed thanks haha
I live in Brazil, the country with the largest amount of lightning strikes EVER. I'm not a victim, but I do know plenty people who got stroke by lightning. One of them was 100 meters from my house. He was an old man with his horse. He jumped of the horse and got stroke while walking away. He died. A group of friends were playing soccer during a rainy and cloudy day when a lightning stroke really close to them. 2 of them died and many more got hurt. Real bad. There are many more examples (just in my little town). As an electronic technician, lightning strikes give me money (I fix all kinds of stuff), but this phenomena is really dangerous here. When nimbus are formed above your head and you're in Brazil, you're quite fucked. Most of the strikes don't come alone: A lot of them happens in a location for minutes. It's not like "One or three strikes per minute". It's more like a machine gun in the sky, shooting real close to you. Surrounding you. Real loud bangs, really close. That's astonishing. The first time I faced a Lightning Storm I couldn't even open the front door without someone yelling back: DON'T GO OUTSIDE YOU STUPID! YOU'RE GONNA GET YOURSELF KILLED! That was fucking serious. I am not kidding. My satellite antenna just fried, as well as many electronics I had. We disconnected everything, but the energy came through the signal wires.
OK, but your country is also like a million times bigger than mine (Netherlands), so it does make sense your get a proportional amount of lightning strikes more.
@@XEinstein also Brasil is close (and part of It at) the Equador. Also also, Brasil is under the biggest failure in earth's magnetic field. Also also also, If I would take a guess, he is from minas gerais, more specificly from the "triangle" region, where the concentration of metals in a not "mineable form" on surfice soil has supposedly increased the odds of a lightning striking the ground instead of clouds nearby.
Ok! That´s enouth!! One of the best ( if it is not THE BEST ) science video on youtube with just 37000 subscribes and few views? What are we going to do about this, guys?
8 yrs ago... that seem so crazy lol i think this was the episode i first found of yours and subbed.. So grateful to have you still putting out content!
About 3 years ago, I witnessed an electric storm in Guadalajara. It was amazing, and it lasted for four hours. Most of the lightnings was in the dense and low clouds, and there was less than one second between the flashes. We get some violent weather here in Denmark, but never light shows like that. I hope to see it again sometime.
Just it is for many of the other viewers, this presentation is the best I have seen and the breaking of the ice crystals is something I had never heard or considered. The graphics are fun as well as helpful. I’m still enjoying the humor and I really like the music at the end.
Hi Nick,i used to go clamming during a thunderstorm.With a long rake standing in a boat.The thunder would shake the ground and the clams would surface,like stomping them.After doing it a while,we got to know when to drop the rake.As we lifted it out of the water the pipe would howl.That was the energy in the air around the rake pipe. Even though there was no direct lightning strike,5 clammers were killed by the energy from not dropping the rake in time.That was in one year. Also i have worked flying a blimp on an airforce base.It had a THOREGUARD which would measure the amount of energy from a lightning bolt and would give the distance from the control tower.It went off the scale sometimes more than100 trillion volts.Thanks for the information though.I do enjoy a good thunderstorm.
Yeah my dad has been struck twice depending on your definition. Once on the peak of a mountain and the other when lightning struck a lake he was in! Survived both times. Is now paranoid about rain clouds.
When I was a young kid, maybe 9, my younger brother and my next door neighbor were standing in my neighbor's back yard. Suddenly, a bolt of lightning struck the ground, maybe 25 feet away from us. I can still remember the ground smoldering. It seemed like the entire Earth shook. I ran so fast into the house, I stepped over my brother and almost smashed through the door. I still wonder to this day why the lightning chose to strike a flat part of the back yard, rather than three kids who were standing a few feet above the ground.
My uncle was indirectly struck by a lightning, he was a crane operator and the lightning struck it. He's alive but his life changed quite a bit, before he was running marathons for fun, after it he was barely able to walk for a year and he had to stop with marathons. By the way, could you explain the dynamics of reverse lightning (earth to cloud)? I have seen some and they are quite fascinating.
Wow. Your videos are actually amazing. Easily subscribed. I bet your channel would blow up with thousands of followers if you just redo the old videos with improved animations and slightly better camera work.
I had a friend once whose house was struck by lightning. It was well past midnight and him and his brother were soundly sleeping in their car-shaped bunks. Outside raged the storm. This was back when Direct TV was the shit, and they had just had it installed. The antena was placed on the outside of their room on the second floor. Naturally, that's where the lightning struck. Its blinding light and cracking sound quaking the room. However, if you've been paying attention, you'll remember my friend was asleep. And no lightning was about to disrupt his rest, so he rolled on his sheets and snored on. His brother wasn't so cool about it thought. The kid sprang from bed and ran to his parents, shouting and flailing his arms as he went. Still my friend slept. Eventually one his parents burst into the room and scooped him, carrying him out of bed in his or her arms. I'm told my friend rolled and complained. Yet, soon was snoring again.
John Phillips the music teacher of lordstown high-school in ohio. He's also a powerlifter, who holds world records. It's daughters wedding was held outside his back yard, he was next to the tent and was struck. He made a full recovery.
Hmm. Dude your channel is sooo underrated. You should have millions of subscribers rather than just 41 thousand. You explain everything so damn good. And got a question aswell.. Why is it possible that people can survive in rare occasion when the lightning strucks them directly, if the amps and voltage is so high and why do some burn to the crisp?? Would be nice to get an aswer.
answer to final question: my parents house had a forked bolt hit on either side of it when we had guests over. i don't remember it as i was too little, but they said it was terrifying and that it struck in front of and behind the house!
Been near lightening strikes quite a few times. On a putting green at a small swimming resort for a friends birth day, lightening struck in the field, it appeared to saw at the grown with its pulses pushing up puffs of dirt. Loud doesn't describe the noise. No one got hit at the resort... they of course closed the swimming pool until the summer storm passed... about 20 minutes.
My dad got struck by lightning at a golf course. It struck the ground between he and his friend. It blew out his L3-L5 vertebrae in his back and he's had intense back pain ever since. It also melted his glasses to his face and melted the golden teeth in his mouth. All he can remember is a bright flash of white thinking that his life was over.
IIRC the third type of lightning is sprites which happen above the clouds. The "arc" color is also different than normal lightnings. Anyways, really love you videos :)
I now wonder, why the pockets of charge build up in the air before lightning forms. And oh, my grandfather was struck by lightning. He survived, but barely. He had to remain in hospital for six weeks (happened in 1925).
Water with electrons on the inside... cool to know and pun about... Need to keep that in mind along with surface tension and density vs. temperature behaviour.
I had lightning strike really close to my house one time. It was so close you could hear the strike before the thunder... Sounded similar to a lightbulb burning out.
This channel gives amazing crazy contents. It's really an asylum-- Science asylum. Thunder is an amazing phenomenon & I like this very much. Every science lover & students should see this channel regularly to make clear concepts on physical phenomena.👍👌 And yeah lightning struck my one elder brother & his army friend. They died instantly.🥺🥺
these videos are great, the reason only few people watch this channel, is because they dont want to watch science in theyr freetime (im the opposite of it if you havent guessed yet) And im just a 9th grade student from germany, actually having to learn the language, to understand the videos. also it is cool to be smarter than a teacher sometimes, and always be the guy with your friends knowing way more advanced stuff than just how a centrifugal force works. Sorry for these long sentences and wrong grammatic, im not a native in any english speaking country, i do just know some words.
my grandad got struck... well he was under a tree that got struck he said his muscles contracted so fast he curled into a ball in midair the smacked into the ground.
A couple months ago it was raining as I was walking home from the gym. Then it started to lightning and the thunder was just about simultaneous, so I knew it was close and started to run. The faster I ran, the closer it got. It's two miles from the gym to my house and I ran the whole way with lightning chasing me.
I got almost hit by a lightning. It was about 12 years ago. A Thunderstorm started and i wanted to briefly go out to reposition my car. I openend the door of the house went two steps, and: It was the brightest, the whitest white i have ever seen. At the same time the loudest Thunder I have ever heard. I was pushed back a few meters back in the house, maybe by a shockwave or scared, shocked, i dont know. Luckily it was all fine, no damage dealt. I just closed the door It was a mighty experience indeed. Odin? :D
I love the cool fireflower scars which lightening strikes leave on stones, trees, the ground, animals and humans. Question, though: How far down does the lightening go down when it lands on the surface of the ocean? As far as light goes? Or further, because of the extra energy? Or less because of the near-magical properties of water?
It doesn't actually go very deep at all. It favors the surface of the ocean... and, even then, it's energy gets absorbed pretty quickly (within 20 feet / 6 meters or so). That doesn't mean you're safe at 21 feet. You still have the sound wave (thunder) to worry about, which is dangerous to a much larger distance.
I heard of someone who was struck by a lightning, second hand, not sure if directly, but she had burns, and shocked. Most lightning here are cloud to cloud/intra-cloud, cloud to ground at sea mostly, the first time I saw cloud to ground up close was at US, quite scary experience.
I believe the part at 1:58 is incorrect. In my years of researching lightning, I haven't ever heard of upward charge patches forming before a CG stroke. Also, what most people who aren't lightning researchers don't realize is that lightning channels not in contact with a surface are bipolar, not unipolar. In other words, a lightning channel will always have a positive end and a negative end. Lightning mapping systems have confirmed this. The current scientific consensus on how a typical CG flash evolves is that it begins as a preliminary breakdown between the main negative charge region and a lower positive charge region (the cloud charge structure is actually more of a tripole than a dipole-- a main positive charge above a main negative charge with a weaker positive charge at the bottom of a cloud). The negative end (positive end) of the leader then propagates downward (upward) from the point of origin. The lower positive charge is generally much weaker than the negative charge region, and is quickly depleted by the negative leader neutralizing it. The negative leader end then seeks the inductively-charged ground, and leaps out of the cloud towards the ground -- often branching in the process. As the negative leader end approaches the ground, upward positive leaders are launched from things on the ground. When these two leaders connect, there is a rapid reduction in resistance at the point where the leaders meet, which allows the current to increase massively. This is the return stroke... the bright part of a CG lightning flash. Dart leader processes often form subsequent return strokes. People interested in learning more about lightning are encouraged to visit the website/blog of Tom Warner (ZT Research) who among other things has really cool slow-motion videos of lightning available. Those interested in the physics of lightning should read the publications of Dr. Vladislav Mazur, as well as works by other people who's names I can't remember off the top of my head.
Since the lighter fragments are already positively charged, why doesn't the lightning zap those, or why doesn't the electric field lasso those smaller pieces back to the bigger pieces? I have a feeling it's got something to do with the scattering of the smaller pieces and the velocity at which they're traveling away... and maybe also the fact that Earth and other clouds are bigger targets with a higher concentration of chargeable stuff, but that's sheer speculation.
I have been "grounded" by a lightning strike once. It was during an electrical storm on a farm at night. I was watching T.V. in the basement and happened to touch the screen (old type that produces electrostatic on the surface of the screen) at the same time a bolt of lightning hit a transformer pole outside. The strike was so powerful that it blew up the transformer and the pole as well! Apparently the current from the strike traveled through the electric wires of the house, then the outlet where the T.V. was plugged into, surging then through the unit and the screen where my finger was touching, through my body and to the ground (or ground to strike??) and giving me a shock that threw me a few feet away. This of course cut off the power to the house. After the shock my heart was racing very fast, producing a panic attack and scaring the **** out of me. The whole incident made me sick for about a week after and teaching me a lesson as well! NEVER TOUCH A T.V. SCREEN DURING A THUNDERSTORM!!! 🇨🇦
I thought a large amount of electrons in the clouds creates a large potential difference between clouds and ground and thus the electrons flow from clouds ( higher potential) to ground ( lower potential) 1:09
Good explanation - had a bad storm last night but the lightning "popped" and boomed - wasn't like a typical lightning storm/strikes. BTW: what is LFTR?
I have a cool lightening story. I live in Detroit. One night I was driving south and noticed the sky flickering directly in front of me. My first thought was that Canada was getting bombarded with lightening. But as I watched some more it started looking strange to me. So, I pulled over to look at the weather radar. The storm was actually across the northern border of Ohio. It was a band of red going across almost the entire border. I initially thought I was looking at the clouds shooting the lightening. But instead I was just seeing the light from the clouds in the night sky. The clouds would've been too far below the horizon for me to see them.
High Nick! I've got a question and a confession all at once: I'm an electrical enginner with a PHD (in mechanical enginnering though) and I still can't understand a ridiculously basic thing: how can more than 20mA flow through your body and YOUR SHOES when you touch 220V WITH ONE HAND. When I measure my body's resistance from hand to hand I have way more than 100kOhm. And the capacity of the human body can't explain it either.
That's because the resistance of your body isn't constant. It might be 100 kOhms when your skin is dry, but it will be _a lot_ lower if your skin is wet (max 1000 ohms). Even if your skin starts dry, the electricity will immediately make you sweat and will eventually melt your skin.
There are more types of lightning but even just considering cloud to ground lightning there are 2 types based on charges. There is negative lightning which is the most common type of lightning and there is positive lightning. Negative lightning has negative charges traveling towards positively charged ground. Positive lightning has positive charges traveling towards the ground. I have heard that negative lightning always comes from the base of the cloud and never veers off far from the storm whereas positive lightning comes from the top of the cloud and always veers off a considerable distance(like 10 miles or more) from the storm. Thus positive lightning is more dangerous because it has a wider lightning strike range. Is it true though that positive lightning is what veers far away from a storm and if both negative and positive lightning can travel downwards, than how can you tell if the lightning you are seeing is negative or positive?
Pecos Hank has a great video covering lightning its called "HOW LIGHTNING WORKS - Weird World of Lightning". He illustrates it with footage of lightning he's collected over the years. I would definitely recommend it to anyone that liked this video.
That's not true. It's only to describe the rarity of getting hit by lightening. Lightening actually can strike in areas multiple times. And often does due to the topology of the area.
The Science Asylum that still doesn't make sense. If the water in the clouds is charged and the ground is charged, shouldn't the snow on the ground act as a medium to decharge the ground and thus prevent lighting in a snow storm?
In a later video of yours, you said that current will complete all possible paths, not just the path of resistance. So I get that by crouching down and have your ankles touching, electricity will pass through your feet, but your whole body and legs are still valid pathways for the current to travel through. Would the current always be small enough that it won't kill you? Or does that depend? Thanks.
You are correct that _some_ of the charge will pass through the rest of your body. By crouching down and having your ankles touching, you're making sure that _most_ of it goes that way and not through your organs. [You still might die, but you're maximizing your chances of living.]
I saw this comment. I see all comments I receive. If I don't reply, it's because of one of three reasons: 1) The comment doesn't really need a response. 2) Other people are answering the question just fine. 3) I don't actually know the answer to the question. Your comment is the third one. I don't know. 🤷♂️
Anytime there is a path from the ionosphere to the ground there is lightning, whether it's a cumulonimbus or ejecta from a volcano. Lightning just needs a path from the positive ionosphere to the negative ground.
I was sitting in my apartment during a summer thunder storm in Hartford, CT about 20 years ago. I saw a tiny finger of blue electricity touch the TV cable right outside my window. The charge traveled down the cable, arced over to the metal window screen, went all the away around the screen and then a blue ball of electricity shot out of the center of the screen and went across the room and hit the wall and dissipated inches from my head. the ball left no mark on the wall. Weirdest thing I've ever seen and I've seen A LOT of weird things.
I'm curious about the electric current that creates the lightning bolt. . For one, the width of that river of electrons. The bolt itself is usually estimated to be on the order of one inch or so, but a lot of that width is probably the hot gas surrounding the current. The wire must be thinner than that. Maybe substantially thinner. . Second, the speed that the electrons are actually moving at peak current. Even in high-current devices, the electrons themselves are not moving very quickly. They might be moving faster in a lightning bolt, but I wonder if it's still slower than, say, a car on the highway. . Lastly, I wonder if the current reverses direction momentarily. When you watch a powerful explosion in slow motion, you can often see the smoke billowing outward, then coming back in slightly, then out again. The momentum of the outward-moving material is so great that for a brief time after the explosion, the pressure at the origin is lower than the pressure of the surrounding air. Maybe when you send a powerful stream of electrons from the sky to the ground very quickly, you can end up with a significantly negatively-charged ground, whose path of least resistance in that moment is the very chain of ionized gas that brought them down there to begin with. Charge, instead of pressure, could cause the current to wobble back and forth, like a rapidly-decaying alternating current. Current bounces around in a resistor-capacitor system. The air is a resistor, and the local ground is like a blurry capacitor. Well, both are both, I guess. . Is it even possible to speculate on these things? . (Sorry for the dots. TH-cam is messing with the line breaks right now unless I put something between them.)
After I watched your other awesome video this video was my next thought! Another question if you have time, I thought electrons move slow through a conductor? Would this include air? Would the poynting vector show energy is flowing up toward the cloud through electro and magnetic fields?
Awesome videos!! I have thought of studying physics or astrophysics too, but I'm a little disappointed because we barely know some facts about the universe. Also, what would I do with my life after finishing studying?. That's why I've decided geophysics. Those two subjects have some things in common, don't they? I hope so :(
High-voltage sparks through the air turns O2 (breathable air) into O3 (toxic ozone). Too much high-voltage in a closed space can make it difficult to breathe.
I get that lightning is blue as per the temp, but I swear that in the summer I see lightning that's purple. Is that an optical illusion or am I drinking too much?
If it gets how enough it could go a little purple, but I doubt that. I would guess it's some absorption of colors by rain (optics), but don't quote me on that.
I was wondering if you have deleted some of your old science videos? I see this video in end card ( the 15 second part of your videos before they end or after you say it's okay to be a little crazy) of your last three videos.... ( Those three videos are 1) the uncertainty principle, 2) 1000 subscribers, 3) why lightning is a thing? ) In them at left bottom the section where you post the previous or recent video's small part.... Yep there in those two boxes There's one video which contains scenes as follows.... " The lady, cake with 22 shaped candle stick and then she is sent outer space in rocket then changed path back to earth. " I have never seen that video of yours. And I have seen this happening in a couple of other videos too. No I am just asking bcuz I want to watch those videos. I was wondering if you could just make a playlist named "deleted videos" and post your old videos which you deleted bcuz they were old needed new info or you just merged them into one video with modifications or something like that. It's bcuz I like to hear your opinions on science related topics. If I have made a mistake plz correct me or tell me. Thanks for providing such great content it just so many just put some sense into what I learnt in class.
The one with the cake is my old twin's paradox video. I deleted that one because I remade it more recently: th-cam.com/video/UInlBJ4UnoQ/w-d-xo.html There's another video I deleted because it was just wrong. I don't make a habit of deleting old videos, but it does happens sometimes.
Why charges in water arranged in the way you say and unlike charges attracts then why the positive charges in the top of the closing don't attract negative charges
@@aku7598 it expands only when it's below 4°C. Above that it behaves normal. Water has the most density in 4°C and less density when it's above or below 4°C. It also expands when it freezes. That's incredibly weird. It may have something to do with the shape of the molecules. I still don't know why.
My father kinda got struck my lightning. He had is hand flipping a light switch he says he felt a sudden charge surge through his body and down to his feet where it hit the ground and he says gravel shot up around his feet. He says within 3 months of this it changed his eye and hair color
Thank You Nick ... but I was hoping you'd say more about lightning ... You ask at the end if we know anyone who has been struck by lightning. I personally do not BUT ... My youngest son had a teacher in High School who has been struck by lightning on 12 separate occasions (not a typo ... ) 12 times, over I forget how many years ... (actually this information was relayed years ago and I no longer trust my memory well ... so let me say ... that could be plus or minus by a factor of 2). The teacher told the story of each event over the course of the school year ... he clearly lived but was injured fairly bad a few times. I also know someone who was engaged to a young man who decided to run the car during a storm and she stood in horror, as she watched him die from one strike. I'm imagining the difference was strength (power or voltage) and directness or how close the exact strike??? I, once, was standing a few inches from a storm door, inside, ... watching some beautiful lightning, when I felt the tingles ... enough for me to back up fast just before a huge flash so close I nearly fell back in terror ... I stand further back now.
12 times?! Ouch! I had heard of someone getting hit 6 or 8 times, but 12? That's so strange and very unlucky. Yes, it is possible to "survive" a lightning strike, but that doesn't mean that you walk away just fine. If it passes through your body, there will always be damage (usually to the nervous system).

@@dizzyshmizzy2624 thanks for looking out for him. I do it all the time and your help is much reflected
Just it is for many of the other viewers, this presentation is the best I have seen and the breaking of the ice crystals is something I had never heard or considered. The graphics are fun as well as helpful. I’m still enjoying the humor and I really like the music at the end.
Beginning of the video: Of course I know what lightening is. Middle of the video: I know shit
Hi Nick,i used to go clamming during a thunderstorm.With a long rake standing in a boat.The thunder would shake the ground and the clams would surface,like stomping them.After doing it a while,we got to know when to drop the rake.As we lifted it out of the water the pipe would howl.That was the energy in the air around the rake pipe.
Even though there was no direct lightning strike,5 clammers were killed by the energy from not dropping the rake in time.That was in one year.
Also i have worked flying a blimp on an airforce base.It had a THOREGUARD which would measure the amount of energy from a lightning bolt and would give the distance from the control tower.It went off the scale sometimes more than100 trillion volts.Thanks for the information though.I do enjoy a good thunderstorm.
That an impressive and varied resume !
Hey! You didn't mention Zeus!
Yeah man. How could he forget that the real cause of lightning is zeus throwing his lightning bolts at earth?
Yeah my dad has been struck twice depending on your definition. Once on the peak of a mountain and the other when lightning struck a lake he was in! Survived both times. Is now paranoid about rain clouds.
Thanks Nick and team.
When I was a young kid, maybe 9, my younger brother and my next door neighbor were standing in my neighbor's back yard. Suddenly, a bolt of lightning struck the ground, maybe 25 feet away from us. I can still remember the ground smoldering. It seemed like the entire Earth shook. I ran so fast into the house, I stepped over my brother and almost smashed through the door. I still wonder to this day why the lightning chose to strike a flat part of the back yard, rather than three kids who were standing a few feet above the ground.
It was feeling merciful.
Amen to that.
Just happened to be the place where it connected, yes a taller object is more likely to connect but that doesn't mean it always is.
My uncle was indirectly struck by a lightning, he was a crane operator and the lightning struck it. He's alive but his life changed quite a bit, before he was running marathons for fun, after it he was barely able to walk for a year and he had to stop with marathons. By the way, could you explain the dynamics of reverse lightning (earth to cloud)? I have seen some and they are quite fascinating.
Wow. Your videos are actually amazing. Easily subscribed.
I bet your channel would blow up with thousands of followers if you just redo the old videos with improved animations and slightly better camera work.
Thanks! I think about it every once in a while, but there's no way to _replace_ a TH-cam video, so it would be a waste of my already limited time.
I had a friend once whose house was struck by lightning.
It was well past midnight and him and his brother were soundly sleeping in their car-shaped bunks. Outside raged the storm. This was back when Direct TV was the shit, and they had just had it installed. The antena was placed on the outside of their room on the second floor. Naturally, that's where the lightning struck. Its blinding light and cracking sound quaking the room.
However, if you've been paying attention, you'll remember my friend was asleep. And no lightning was about to disrupt his rest, so he rolled on his sheets and snored on.
His brother wasn't so cool about it thought. The kid sprang from bed and ran to his parents, shouting and flailing his arms as he went. Still my friend slept.
Eventually one his parents burst into the room and scooped him, carrying him out of bed in his or her arms.
I'm told my friend rolled and complained. Yet, soon was snoring again.
John Phillips the music teacher of lordstown high-school in ohio. He's also a powerlifter, who holds world records. It's daughters wedding was held outside his back yard, he was next to the tent and was struck. He made a full recovery.
Hmm. Dude your channel is sooo underrated. You should have millions of subscribers rather than just 41 thousand. You explain everything so damn good. And got a question aswell.. Why is it possible that people can survive in rare occasion when the lightning strucks them directly, if the amps and voltage is so high and why do some burn to the crisp?? Would be nice to get an aswer.
answer to final question: my parents house had a forked bolt hit on either side of it when we had guests over. i don't remember it as i was too little, but they said it was terrifying and that it struck in front of and behind the house!
it also wound up taking a while to fix everything
Been near lightening strikes quite a few times.
On a putting green at a small swimming resort for a friends birth day, lightening struck in the field, it appeared to saw at the grown with its pulses pushing up puffs of dirt. Loud doesn't describe the noise.
No one got hit at the resort... they of course closed the swimming pool until the summer storm passed... about 20 minutes.
I LOVE YOUR VIDEOS! Youre a AWESOME presentor, please NEVER STOP DOING VIDEOOOOOOOOOOOOOOS
Thanks!
My dad got struck by lightning at a golf course. It struck the ground between he and his friend. It blew out his L3-L5 vertebrae in his back and he's had intense back pain ever since. It also melted his glasses to his face and melted the golden teeth in his mouth. All he can remember is a bright flash of white thinking that his life was over.
WOW!
IIRC the third type of lightning is sprites which happen above the clouds. The "arc" color is also different than normal lightnings. Anyways, really love you videos :)
I'm intrigued about how water droplets freeze with more positive charges on the outside. *Heads off to Wikipedia*
that's awesome dude...great explanation..best of luck...
I now wonder, why the pockets of charge build up in the air before lightning forms. And oh, my grandfather was struck by lightning. He survived, but barely. He had to remain in hospital for six weeks (happened in 1925).
Very good explanation.
Water with electrons on the inside... cool to know and pun about...
Need to keep that in mind along with surface tension and density vs. temperature behaviour.
I had lightning strike really close to my house one time. It was so close you could hear the strike before the thunder... Sounded similar to a lightbulb burning out.
He is so young. Hello from 2021.
This was soooooooo long ago.
To an alien coming from a controlled environment simply standing on the Earth's surface could feel like a thrill-ride.
This channel gives amazing crazy contents. It's really an asylum-- Science asylum. Thunder is an amazing phenomenon & I like this very much. Every science lover & students should see this channel regularly to make clear concepts on physical phenomena.👍👌
And yeah lightning struck my one elder brother & his army friend. They died instantly.🥺🥺
these videos are great, the reason only few people watch this channel, is because they dont want to watch science in theyr freetime (im the opposite of it if you havent guessed yet) And im just a 9th grade student from germany, actually having to learn the language, to understand the videos. also it is cool to be smarter than a teacher sometimes, and always be the guy with your friends knowing way more advanced stuff than just how a centrifugal force works. Sorry for these long sentences and wrong grammatic, im not a native in any english speaking country, i do just know some words.
my grandad got struck... well he was under a tree that got struck he said his muscles contracted so fast he curled into a ball in midair the smacked into the ground.
OUCH!
Yep, same happened to my granddad. It seems to be a granddad thing to do. Mine was in hospital for six weeks after that.
A couple months ago it was raining as I was walking home from the gym. Then it started to lightning and the thunder was just about simultaneous, so I knew it was close and started to run. The faster I ran, the closer it got. It's two miles from the gym to my house and I ran the whole way with lightning chasing me.
Liam McIrishman HAHAHAHHAHAHAHA BRO i start imagining the situation there i can't handle feeling
Great video! Super crazy science....
I got almost hit by a lightning. It was about 12 years ago. A Thunderstorm started and i wanted to briefly go out to reposition my car. I openend the door of the house went two steps, and:
It was the brightest, the whitest white i have ever seen. At the same time the loudest Thunder I have ever heard. I was pushed back a few meters back in the house, maybe by a shockwave or scared, shocked, i dont know.
Luckily it was all fine, no damage dealt.
I just closed the door
It was a mighty experience indeed.
Odin? :D
"Water is weird..." - Nick Lucid
I think I am going to quot this offten hehe
*Water is weirder than quantum mechanics.* Here, said it. Or is it?
I love the cool fireflower scars which lightening strikes leave on stones, trees, the ground, animals and humans. Question, though: How far down does the lightening go down when it lands on the surface of the ocean? As far as light goes? Or further, because of the extra energy? Or less because of the near-magical properties of water?
It doesn't actually go very deep at all. It favors the surface of the ocean... and, even then, it's energy gets absorbed pretty quickly (within 20 feet / 6 meters or so). That doesn't mean you're safe at 21 feet. You still have the sound wave (thunder) to worry about, which is dangerous to a much larger distance.
I heard of someone who was struck by a lightning, second hand, not sure if directly, but she had burns, and shocked.
Most lightning here are cloud to cloud/intra-cloud, cloud to ground at sea mostly, the first time I saw cloud to ground up close was at US, quite scary experience.
Nice Jacobs ladder. Did you make that yourself?
Jamie Godman Yep... using a microwave oven transformer.
I believe the part at 1:58 is incorrect. In my years of researching lightning, I haven't ever heard of upward charge patches forming before a CG stroke. Also, what most people who aren't lightning researchers don't realize is that lightning channels not in contact with a surface are bipolar, not unipolar. In other words, a lightning channel will always have a positive end and a negative end. Lightning mapping systems have confirmed this. The current scientific consensus on how a typical CG flash evolves is that it begins as a preliminary breakdown between the main negative charge region and a lower positive charge region (the cloud charge structure is actually more of a tripole than a dipole-- a main positive charge above a main negative charge with a weaker positive charge at the bottom of a cloud). The negative end (positive end) of the leader then propagates downward (upward) from the point of origin. The lower positive charge is generally much weaker than the negative charge region, and is quickly depleted by the negative leader neutralizing it. The negative leader end then seeks the inductively-charged ground, and leaps out of the cloud towards the ground -- often branching in the process. As the negative leader end approaches the ground, upward positive leaders are launched from things on the ground. When these two leaders connect, there is a rapid reduction in resistance at the point where the leaders meet, which allows the current to increase massively. This is the return stroke... the bright part of a CG lightning flash. Dart leader processes often form subsequent return strokes. People interested in learning more about lightning are encouraged to visit the website/blog of Tom Warner (ZT Research) who among other things has really cool slow-motion videos of lightning available. Those interested in the physics of lightning should read the publications of Dr. Vladislav Mazur, as well as works by other people who's names I can't remember off the top of my head.
Well that about sums up "research" then, doesn't it? Go get that grant money.
I want to see Nick respond to this.
Since the lighter fragments are already positively charged, why doesn't the lightning zap those, or why doesn't the electric field lasso those smaller pieces back to the bigger pieces? I have a feeling it's got something to do with the scattering of the smaller pieces and the velocity at which they're traveling away... and maybe also the fact that Earth and other clouds are bigger targets with a higher concentration of chargeable stuff, but that's sheer speculation.
I have been "grounded" by a lightning strike once. It was during an electrical storm on a farm at night. I was watching T.V. in the basement and happened to touch the screen (old type that produces electrostatic on the surface of the screen) at the same time a bolt of lightning hit a transformer pole outside. The strike was so powerful that it blew up the transformer and the pole as well! Apparently the current from the strike traveled through the electric wires of the house, then the outlet where the T.V. was plugged into, surging then through the unit and the screen where my finger was touching, through my body and to the ground (or ground to strike??) and giving me a shock that threw me a few feet away. This of course cut off the power to the house. After the shock my heart was racing very fast, producing a panic attack and scaring the **** out of me. The whole incident made me sick for about a week after and teaching me a lesson as well! NEVER TOUCH A T.V. SCREEN DURING A THUNDERSTORM!!! 🇨🇦
Yikes! Also, never _shower_ during a lightning storm. If your home isn't properly grounded, you're a goner.
LOVE your videos!
Thanks!
I thought a large amount of electrons in the clouds creates a large potential difference between clouds and ground and thus the electrons flow from clouds ( higher potential) to ground ( lower potential) 1:09
Good explanation - had a bad storm last night but the lightning "popped" and boomed - wasn't like a typical lightning storm/strikes. BTW: what is LFTR?
I have a cool lightening story. I live in Detroit. One night I was driving south and noticed the sky flickering directly in front of me. My first thought was that Canada was getting bombarded with lightening. But as I watched some more it started looking strange to me. So, I pulled over to look at the weather radar. The storm was actually across the northern border of Ohio. It was a band of red going across almost the entire border. I initially thought I was looking at the clouds shooting the lightening. But instead I was just seeing the light from the clouds in the night sky. The clouds would've been too far below the horizon for me to see them.
High Nick! I've got a question and a confession all at once: I'm an electrical enginner with a PHD (in mechanical enginnering though) and I still can't understand a ridiculously basic thing: how can more than 20mA flow through your body and YOUR SHOES when you touch 220V WITH ONE HAND. When I measure my body's resistance from hand to hand I have way more than 100kOhm. And the capacity of the human body can't explain it either.
That's because the resistance of your body isn't constant. It might be 100 kOhms when your skin is dry, but it will be _a lot_ lower if your skin is wet (max 1000 ohms). Even if your skin starts dry, the electricity will immediately make you sweat and will eventually melt your skin.
You are the best teacher I ever had. Wish I was born some years late.
What's crazy is the fact that despite all these numbers, lightning stroke has mortality rate of just between 10% and 30%.
When my grandma was a kid, she and her sister was playing and then, a lightning strike hits close to the house and make all of the sister fell down
Cade as legendas nick?
My granddad was struck by lightning, well... technically the tree he was under was struck. 6 weeks in hospital, but he survived.
Probably some permanent nervous system damage though.
There are more types of lightning but even just considering cloud to ground lightning there are 2 types based on charges. There is negative lightning which is the most common type of lightning and there is positive lightning. Negative lightning has negative charges traveling towards positively charged ground. Positive lightning has positive charges traveling towards the ground. I have heard that negative lightning always comes from the base of the cloud and never veers off far from the storm whereas positive lightning comes from the top of the cloud and always veers off a considerable distance(like 10 miles or more) from the storm. Thus positive lightning is more dangerous because it has a wider lightning strike range.
Is it true though that positive lightning is what veers far away from a storm and if both negative and positive lightning can travel downwards, than how can you tell if the lightning you are seeing is negative or positive?
Pecos Hank has a great video covering lightning its called "HOW LIGHTNING WORKS - Weird World of Lightning". He illustrates it with footage of lightning he's collected over the years. I would definitely recommend it to anyone that liked this video.
Why does the ice freeze like that? Where can i find out more about that specifically?
So, why lightning is not striking same place nor point twice?
That's not true. It's only to describe the rarity of getting hit by lightening. Lightening actually can strike in areas multiple times. And often does due to the topology of the area.
jmitterii2 hmm, thank you for info.
So how is lightning possible during snow storms?
Because it's all ice up in the cloud. If it's raining, that just means it was warm enough down here to melt on the way down.
The Science Asylum that still doesn't make sense. If the water in the clouds is charged and the ground is charged, shouldn't the snow on the ground act as a medium to decharge the ground and thus prevent lighting in a snow storm?
Lightning during a snow storm (thundersnow) is much more rare than it is in rain storm, so you might be onto something there.
The Science Asylum Would a single section of exposed ground be sufficient to enable lightning, or would the surrounding snow just suck out the charge?
@1:35 THANK YOU!
but the actual material blue white thing we see is air plasma right?
Your vids are very nice
how can water freeze in low-pressure won't it evaporate instead due to low pressure because atoms cant be close together @ 0:40
th-cam.com/video/87v_9Bud7vw/w-d-xo.html hope this helps
You should include details about Lichtenberg figures on lightening strike victims.
In a later video of yours, you said that current will complete all possible paths, not just the path of resistance. So I get that by crouching down and have your ankles touching, electricity will pass through your feet, but your whole body and legs are still valid pathways for the current to travel through. Would the current always be small enough that it won't kill you? Or does that depend? Thanks.
You are correct that _some_ of the charge will pass through the rest of your body. By crouching down and having your ankles touching, you're making sure that _most_ of it goes that way and not through your organs. [You still might die, but you're maximizing your chances of living.]
What does the ground to sky charges look like?
@The Science Asylum What is the cause of the arrangement of charges in the ice crystals as shown in your video ?
I saw this comment. I see all comments I receive. If I don't reply, it's because of one of three reasons:
1) The comment doesn't really need a response.
2) Other people are answering the question just fine.
3) I don't actually know the answer to the question.
Your comment is the third one. I don't know. 🤷♂️
@@ScienceAsylum no problem . I will look out for that.😌 Thanks for your reply.😀
@@ScienceAsylum you are genuine 👍
Anytime there is a path from the ionosphere to the ground there is lightning, whether it's a cumulonimbus or ejecta from a volcano. Lightning just needs a path from the positive ionosphere to the negative ground.
I was sitting in my apartment during a summer thunder storm in Hartford, CT about 20 years ago. I saw a tiny finger of blue electricity touch the TV cable right outside my window. The charge traveled down the cable, arced over to the metal window screen, went all the away around the screen and then a blue ball of electricity shot out of the center of the screen and went across the room and hit the wall and dissipated inches from my head. the ball left no mark on the wall. Weirdest thing I've ever seen and I've seen A LOT of weird things.
That's.... terrifying.
@@ScienceAsylum In retrospect yes but I was pretty baked at the time so I just thought it was cool.
In a cloud to ground lightning discharge. What happens to positive charges that went up.
I'm curious about the electric current that creates the lightning bolt.
.
For one, the width of that river of electrons. The bolt itself is usually estimated to be on the order of one inch or so, but a lot of that width is probably the hot gas surrounding the current. The wire must be thinner than that. Maybe substantially thinner.
.
Second, the speed that the electrons are actually moving at peak current. Even in high-current devices, the electrons themselves are not moving very quickly. They might be moving faster in a lightning bolt, but I wonder if it's still slower than, say, a car on the highway.
.
Lastly, I wonder if the current reverses direction momentarily. When you watch a powerful explosion in slow motion, you can often see the smoke billowing outward, then coming back in slightly, then out again. The momentum of the outward-moving material is so great that for a brief time after the explosion, the pressure at the origin is lower than the pressure of the surrounding air. Maybe when you send a powerful stream of electrons from the sky to the ground very quickly, you can end up with a significantly negatively-charged ground, whose path of least resistance in that moment is the very chain of ionized gas that brought them down there to begin with. Charge, instead of pressure, could cause the current to wobble back and forth, like a rapidly-decaying alternating current. Current bounces around in a resistor-capacitor system. The air is a resistor, and the local ground is like a blurry capacitor. Well, both are both, I guess.
.
Is it even possible to speculate on these things?
.
(Sorry for the dots. TH-cam is messing with the line breaks right now unless I put something between them.)
How do you manage those animations???
Arindam Banerjee Lots of time and planning. They're the biggest reason I can't make videos any faster than I do.
@@ScienceAsylum wow. Do you animate them yourself? Cool :)
Don't you have a friend who can help you with animating? Just asking.
After I watched your other awesome video this video was my next thought! Another question if you have time, I thought electrons move slow through a conductor? Would this include air? Would the poynting vector show energy is flowing up toward the cloud through electro and magnetic fields?
Awesome videos!! I have thought of studying physics or astrophysics too, but I'm a little disappointed because we barely know some facts about the universe. Also, what would I do with my life after finishing studying?. That's why I've decided geophysics. Those two subjects have some things in common, don't they? I hope so :(
Alexandra Mayor Have you found out what were those things in common?
We know more than you think. And after 3 years I hope you have learnt a lot of things.
But why does the lightning make that boom noise which i don’t remember the name of it in english?
Each stroke gives huge energy.Can the energy be stored in a capacitor?
Why inside a car or house the lightning passes around ?
Capacitors can only be charged so quickly without getting damaged. A lightning strike happens a bit too quickly for that.
Wow so much info, btw I saw the storm clones lol.
beginner question:
if i use a battery, i need to close a circut for the charge to flow. why doesn't lightning need a closed circut?
If the voltage is high enough, you don't need a closed circuit for charge to move. We can do this in labs with high-voltage power supplies too.
Look up Tesla coils
What happened at 3:09?
High-voltage sparks through the air turns O2 (breathable air) into O3 (toxic ozone). Too much high-voltage in a closed space can make it difficult to breathe.
I get that lightning is blue as per the temp, but I swear that in the summer I see lightning that's purple. Is that an optical illusion or am I drinking too much?
If it gets how enough it could go a little purple, but I doubt that. I would guess it's some absorption of colors by rain (optics), but don't quote me on that.
Never struck by lightning but my brother's hair once stood up... that was a close call.
Yikes!
I was wondering if you have deleted some of your old science videos?
I see this video in end card ( the 15 second part of your videos before they end or after you say it's okay to be a little crazy)
of your last three videos....
( Those three videos are 1) the uncertainty principle, 2) 1000 subscribers, 3) why lightning is a thing? )
In them at left bottom the section where you post the previous or recent video's small part....
Yep there in those two boxes
There's one video which contains scenes as follows....
" The lady, cake with 22 shaped candle stick and then she is sent outer space in rocket then changed path back to earth. "
I have never seen that video of yours.
And I have seen this happening in a couple of other videos too.
No I am just asking bcuz I want to watch those videos.
I was wondering if you could just make a playlist named "deleted videos" and post your old videos which you deleted bcuz they were old needed new info or you just merged them into one video with modifications or something like that.
It's bcuz I like to hear your opinions on science related topics.
If I have made a mistake plz correct me or tell me.
Thanks for providing such great content it just so many just put some sense into what I learnt in class.
The one with the cake is my old twin's paradox video. I deleted that one because I remade it more recently: th-cam.com/video/UInlBJ4UnoQ/w-d-xo.html
There's another video I deleted because it was just wrong. I don't make a habit of deleting old videos, but it does happens sometimes.
@@ScienceAsylum
I see, thank you very much for replying.
0:40 😂😂 good one
0:53 I just don't know why I laugh Everytime I hear him scream BOOM!
Nice clock!
Why charges in water arranged in the way you say and unlike charges attracts then why the positive charges in the top of the closing don't attract negative charges
I wonder if light follows the same path as lightning I mean it sort of branches out and the distance from branch to branch is it's wavelength.
"water is weird" _Nick Lucid
Indeed.
P.S : that evil laugh always gets me😂😂😂😂
I replayed it over ten times and I still laugh hard.
yeah...it expands when cooled.
@@aku7598 it expands only when it's below 4°C. Above that it behaves normal. Water has the most density in 4°C and less density when it's above or below 4°C. It also expands when it freezes. That's incredibly weird.
It may have something to do with the shape of the molecules. I still don't know why.
My father kinda got struck my lightning. He had is hand flipping a light switch he says he felt a sudden charge surge through his body and down to his feet where it hit the ground and he says gravel shot up around his feet. He says within 3 months of this it changed his eye and hair color
Thank You Nick ... but I was hoping you'd say more about lightning ... You ask at the end if we know anyone who has been struck by lightning. I personally do not BUT ... My youngest son had a teacher in High School who has been struck by lightning on 12 separate occasions (not a typo ... ) 12 times, over I forget how many years ... (actually this information was relayed years ago and I no longer trust my memory well ... so let me say ... that could be plus or minus by a factor of 2). The teacher told the story of each event over the course of the school year ... he clearly lived but was injured fairly bad a few times. I also know someone who was engaged to a young man who decided to run the car during a storm and she stood in horror, as she watched him die from one strike. I'm imagining the difference was strength (power or voltage) and directness or how close the exact strike???
I, once, was standing a few inches from a storm door, inside, ... watching some beautiful lightning, when I felt the tingles ... enough for me to back up fast just before a huge flash so close I nearly fell back in terror ... I stand further back now.
12 times?! Ouch! I had heard of someone getting hit 6 or 8 times, but 12? That's so strange and very unlucky. Yes, it is possible to "survive" a lightning strike, but that doesn't mean that you walk away just fine. If it passes through your body, there will always be damage (usually to the nervous system).
What about ball lightening ?
But what is ball lightning?
I’ve heard of a guy in Virginia named Roy Sullivan who got struck by lightning seven times and survived them all!
