If anyone has a sense of history and they look at the publication date, they will ask "Why did they hold this during the middle of a pandemic?" The obvious answer - that it was held before the pandemic - won't be obvious to some. So, you post the clarifying comment to avoid needing to do something like this...
What I learn : -Negative meets Negative they don't stick -Opposite charges stick -Lightning is more hot that the surface of the sun -It takes to second for a sound to travel 1 mile -I failed basic science & math -I need to go back to school
14:31 Teacher: "if it's negative and it's attracted to this what's this?" Student: "positive" Teacher: "how could this be positive?" Student: "because it is"
One atom says to another, "Hey! I have lost an electron." The second atom says, "Are you sure?" The first atom says, "Yes. I'm positive." (My apologies: old physics joke.)
This guy explained it better in 15 minutes than my tech teacher did over the course of 9 months (also that little "fly, be free, go!" with the packing peanuts was peak comedy)
yeah but he only touched it when the other dome was in contact with the first dome, so electrons from the main dome travelled to the earth thru the second dome and didnt affect him. if he wouldve just touched the dome directly he wouldve been electrocuted.
"What's the largest thing around?" -YOU! "Uuhhh not me 🙄 what's the largest thing around?" -THE EARTH! "YES! I'm not larger than the planet thank you very much" Wow that got me omg 🤣🤣🤣🤣
There's a reason why the title includes "A Prequel to 'Should a Person Touch 200,000 Volts?'" The resolution to the cliffhanger already exists in an older video called... Should a Person Touch 200,000 Volts? Links are in the description, or right here: th-cam.com/video/ubZuSZYVBng/w-d-xo.html
In space? Like, in vacuum? Well, for starters, with the same tools, it would be a very quick presentation as the presenter would quickly die. And, the Van de Graaff wouldn't do nearly as much as it depends on the resistivity of the air to allow charges to collect on its dome.
Electricity doesn't pick the easier way. Instead the least resistance draws the highest current. And the purpose of ground is to draw high current so the circuit breaker kicks in when the safety of conductive casing is compromised.
How fast can a jet make it around the world? GlobalFlyer landed at Salina at 19:50 UTC (13:50 CST) on 3 March 2005, having completed its circumnavigation in 2 days, 19 hours, 1 minute and 46 seconds. As of 2019, this is the fastest world trip in its class at a speed of 550.78 km/h. The light takes roughly 130 ms to travel around the earth - that is seven and a half times round per second.
Teacher: Plastic make good....? Student: Plastic 4:00 Teacher: What's the largest thing around? Student: You!! 7:05 Teacher: Why is that called that ground? Student: Because it's the ground!! 7:55 So many Genius Moments!!

How come the plastic pieces still repelled each other after putting the nail between them? The nail is a conductor and so are you so how come they didn’t lose their negative charge when you did that? Was the current too slow to discharge the static electricity?
The nail is a conductor, but the plastic isn't. Touching the nail to the plastic doesn't allow for the bulk of the charge to move to ground. If a charge happens to be somewhere other than where the nail is touching, it's difficult for it to move through the plastic to get to the nail. So, the plastic remains charged, even when the nail is placed between them.
I assume it's because the microphone is behaving like a boat in the ocean. While a boat rises and falls with the tide, internally, though, nothing changes. So, if the microphone's ground is allowed to float, it doesn't matter if the surrounding 'ocean' is at a high tide or a low tide. Internally, a five volt drop is still a five volt drop.
@@JeffersonLab But in your previous video when you were touching the VDG while standing on the stool...why the electrons were getting stored in you but not passing through the microphone's ground connection..i mean shouldn't it behave as a ground connection in your body.
Please Note: This was recorded before the onset of the current pandemic.
Wow. Sir u r still here!! I pove the way u teach. 11 yrs ago sir 🙂🙂🤗
I also just watched the 12 years old
why being apologetic about not wearing masks

The 2021 episode of everyone’s favourite yearly series!
Such an awesome teacher. Breaks things down so they’re easier to grasp, and understand.
true
This man is still going after 12 years, wow... You're amazing!
3:57 teacher: "plastic makes good-"
student: "plastic!"
They're not wrong.
What I learn :
-Negative meets Negative they don't stick
-Opposite charges stick
-Lightning is more hot that the surface of the sun
-It takes to second for a sound to travel 1 mile
-I failed basic science & math
-I need to go back to school
Lol
5 seconds for a mile
You are here after the 10 years later recommended video 💢
Maybe
How’d you know
Yes
Becuz ur too
He has became opd
Very expensive piece of scientific equipment
(Two pieces of plastic and a clip)

You are a awesome teacher.
We need more teachers like you😍😍😍
an
Dude.. i love you! If everyone gets teacher like you, students interest in physics will be increased exponentially!
Not to be TOO fanboyish, but your enthusiasm in teaching does Carl Sagan proud. 👍
I'm 54 years old and I'm finally understanding electricity! I can't wait to see your other videos!
Great job, thank you for your hard work!!
I love this hahahaha, I wish more teachers made explaining all concepts more entertaining!
Wow... i just saw your 10 year old video and came here to find this new video! Sir, please keep up the good work
My favorite teacher ever
The best session of physics teaching I ever attended. So impressed and happy!
10:41 "not space we all would be dead" :)
this man is gonna help me not fail electricity.
This dude is sutch a good teacher tho.
11 years later and still teaching students. What a legend
14:33
+How'd this get to be positive?
-'Cause it is.
And we called that "The Science"
The great and mighty, Steve!
At the end he is like: "Should a person touch it?"
But touched it several times before in the video.
yeah but he only touched it when the other dome was in contact with the first dome, so electrons from the main dome travelled to the earth thru the second dome and didnt affect him. if he wouldve just touched the dome directly he wouldve been electrocuted.
@@dripcat5940 He touches it directly here: th-cam.com/video/ubZuSZYVBng/w-d-xo.html
I’m in 10th grade from india , all my portions make sense with such explanation. It’s genius ❤️
such a refreshing style of lecture presentation
"Plastic makes..?
*P L A S T I C*
They're not wrong...
@@JeffersonLab technically...
Yep. Sometimes, that'll all one has.
Love these lessons
Loved the way you teach
"What's the largest thing around?"
-YOU!
"Uuhhh not me 🙄 what's the largest thing around?"
-THE EARTH!
"YES! I'm not larger than the planet thank you very much"
Wow that got me omg 🤣🤣🤣🤣
Plastics makes good "plastics (from behind)" 😂😂
"Plastics make good...PLASTICS"
The kid who said that is a genius
He's channeling his inner Mr. McGuire.
well, My fav. online teacher is getting older. thank you Jefferson for making our study so easy🙂
"Fly! Be free! Go! 😂😂😂
4:01 Plastics make good...
Random genius: p l a s t i c
Love watching your videos they’re so helpful in learning some pretty tricky concepts
Lol i like how he is acting and making students paniiiikkk whenever he tries something new🤣
Simply wonderful 🥰
Funny demostration
After some poking around on Google, I think his name is Steve Gagnon. He is just awesome!
I watched you 10 years ago....here you are still very passionate.....#proudtobeateacher
"Two pieces of plastic 🤤"
sounded like Ryan Reynolds on DeadPool.
Nice to see this guy 11 years later
Electricity and statically driven charges wonderful.
4:01
Teacher: "Plastics make good..."
One kid: "Plastics!"
Well... they aren't wrong...
Damn video ended on the main cliffhanger, I wanted to see someone touch the dome with the belt in it.
There's a reason why the title includes "A Prequel to 'Should a Person Touch 200,000 Volts?'" The resolution to the cliffhanger already exists in an older video called... Should a Person Touch 200,000 Volts? Links are in the description, or right here: th-cam.com/video/ubZuSZYVBng/w-d-xo.html
I learned more in this one video than I did in a whole year of high school.
4:03
teacher: plastics make good?
Student: plastics....
😆
2:08 i also thought same when I heard charge accelerator
You are a Great real teacher. Hope you are doing well.
So far, so good. Hope you're doing well as well.
"if you could run at the speed of light you could run around the earth 7 times in a second."
Me: the catch is you'll be a cooked corndog.
teacher: plastics make good...
student:plastics
dying rn

May be 12 years ago but this dude sure still knows his stuff
This isn't from 12 years ago (yet). This was early 2020.
I wonder what if you would try this experiment out in space with the same tools?
In space? Like, in vacuum? Well, for starters, with the same tools, it would be a very quick presentation as the presenter would quickly die. And, the Van de Graaff wouldn't do nearly as much as it depends on the resistivity of the air to allow charges to collect on its dome.
ahh yes, plastic makes good plastic
4:00
We've found that plastic is the best substitute for plastic.
OMG! It's two pieces of plastic! They really saved no expenses lol ☺
Timing it right is the key .
would that spark burn your finger if touched (as it is hotter than the suns surface)?
One spark? No. But, if you had a constant arc going for long enough, you'd start to run into trouble.
thanks
This dude is just AWESOME
Yes, student in the back. Plastic does make pretty good plastic!
Thank you teacher
Today I learned that plastics make good plastics. And something about insulator.
Insulators make good insulators.
Hey Jeff , you got old man....!!!
Beats the alternative.
@@JeffersonLab LOL!!!!
I'm Always Waiting:")
Very good explanation 👏
Here before it gets recommended to everyone 10 years later
Mr. Jefferson... Just a small indispansable question : Is all of that magical actions came out of a coincidence? 🤔
Electricity doesn't pick the easier way. Instead the least resistance draws the highest current. And the purpose of ground is to draw high current so the circuit breaker kicks in when the safety of conductive casing is compromised.
#good_one👌🏻

Denki Kaminari loves this guy
He should get best teacher award 🥇
Name of Professor?
cewl stuff.
Please explain why this matters, what part of GR, SR, are we missing. Seems like Einstein is still 100 years ahead of us
hats off to science sir❤
School would have been great if it was like this
Hail Legend 🙌 🙌 🙌 🙌.. true hercules..
Can someone tell me his full name?
Nice video
Thanks!
Amazing
Oh so that’s why Pikachu never kill anyone
4:01 me in class (turn subtitles on)
sir I have a question that why opposite charge attract and same charge repel each other???
Did your watch work afterwards?
Yes. Watch is fine.
what kind of plastic is that?
It's a piece of overhead projector transparency film.
14:34
Q: Why is it positive?
A: Proton
man you still look good and you still got hair lol
if he teaches me physics then i can challenge Einstein face to face
Hahaha 🤣
Lot more grey hair 12 yrs later :D; just for reference I have a grey hair 12 years later too
True. At least the hair is still there.
Mostly.
So, how does the microphone stay functioning while you're touching the VDG? I have a job where I do a science show and I have a talk box on me.
I assume it's because the microphone is behaving like a boat in the ocean. While a boat rises and falls with the tide, internally, though, nothing changes. So, if the microphone's ground is allowed to float, it doesn't matter if the surrounding 'ocean' is at a high tide or a low tide. Internally, a five volt drop is still a five volt drop.
@@JeffersonLab But in your previous video when you were touching the VDG while standing on the stool...why the electrons were getting stored in you but not passing through the microphone's ground connection..i mean shouldn't it behave as a ground connection in your body.
The microphone doesn't have a ground connection.
Nice
same watch ?
Yep. Might be a different battery, though.
