Cody'sLab I have a great idea for another movie - "anti-gravity" propulsion from microwaves and flame. Fire in microwave owen turns into ball of plasma, which is opposing gravity. I saw on youtube a guy, who made a "microwave gun" from an old owen. If you would use such "gun" on an open fire outside the house, the ball of plasma would fly up to the sky. It should be also posiible to use this force, to lift things into sky. If the plasma ball would be exposed constantly to the microwaves, it could theoretically fly all the way to space...
If the plasma isnt contained it will probably just expand and fizzle out. Also a microwave produces standing waves wich is probably necessecary to create the "ball"-phenomenon. Maybe a vertical tube with a metall cap on one side an the magnetron on the other end could make a rising plasmaball. Maybe jumping from one wave maximum to the next wich might look cool in slow motion.

I accidentally left a single blueberry in a open container in my room right before a 5 day vacation. When my family got back, there were a million fruit flies in the container, and tons of maggots. What the hell? It was a single fucking blueberry lmao. The same thing happened with a banana, but I just forgot about it instead of leaving for a week. It was underneath a bag on a chair in my room, and when I was cleaning my room, I found it. I lifted the bag and behold, a black banana with hundreds of flies, maggots, and unhatched maggots. I had small fruit flies in my room for at least a couple weeks and had no idea why. Moral of the story: *DON'T LEAVE FRUIT IN ROOM*

(though those are the people that came only for the flies exploding and don't care for the science)
not everything though, i meant that for a video not focused on that it was good, not great, just good(well, for a video of fruit flies in a microwave it's enough)
Could you do a quick video explaining how the grape in the microwave creates plasma? Maybe about plasma in general aswell. Ive done it myself but I dont understand it fully and would love to learn more about it. ^^
AlieZ92 in this video, he explains the presence of an electric potential and current accross the two sides of the grape. This electric potential is higher than the breakdown voltage of atmospheric air, so the molecules in the air get their electrons ripped out of them by force and the air becomes ionized and conductive. The current then flows accross the air and heats up the air. And then from there it's a similar concept to fire.
Alright, but when I did this the plasma moved around upwards, in circles and what seemed like random movements upwards, not at all acting like fire. Do you know why and how?
AlieZ92 like how fire tends to point upwards, the rising hot air/plasma is what draws the plasma upwards. However, unlike fire the source of the plasma (potential difference) is stuttered, so there won't be a constant stream coming out of the grape. At the same time, plasma in itself is also conductive, and will itself also respond to microwaves. The plasma is able to remain in the plasma state even after it moves away from it's origin because it is kept heated by microwaves, unlike fire which loses its heat after it flows up and away from the source.

Cody - your videos are awesome! I do have a little bit of an issue with your explanation here, though. Even RF with a wavelength much longer than an animal can indeed hurt the animal. Consider a person standing near an AM radio transmitting antenna. It is true that it needs to be stronger than if it were shorter, but not ridiculously so. I think what is more at play here is the average power per volume in the microwave, the small volume of the insects, and their surface area to volume ratio. If you have a 1kW microwave with internal dimensions 33cmx33cmx33cm, you have about 0.04m^3 physical volume. Since the microwaves do not fill the cavity evenly but instead form a standing wave, let's say that the effective volume over which the energy is distributed is only 10% of the physical volume, so 0.004m^3. This implies an average of 250kW/m^3 in the areas near the standing wave peaks. If an insect is about 1mm^3, that's 10^-9 m^3, so it would absorb only 250 microwatts. Even though the volume of the insect is tiny, its surface area is still respectable because that goes as length squared instead of cubed, so the insect is easily able to dissipate an extra 250 microwatts without rising in temperature much at all. In fact, the average energy use of an active fruit fly, as far as I can tell from Google, is about 300uW, which they dissipate without getting much hotter than their surroundings.
That was really quite a good explanation of how microwaves interact with things and why they reflect off metal surfaces including holes. Thanks! A couple tiny issues though: the electric and magnetic fields are not 90 degrees out of phase, but oriented 90 degrees apart from each other. Also, the reflected wave is 180 degrees out of phase, not 90 degrees out of phase.
Mentioned this higher up. You don't even walk out onto transmission dishes (on large antennas) without them switched off (Even if they're not operating). You'll get fried. Transmission power for mobile phone (cell phone) towers can be anything up to several kW, running on several kV. Without proper RF knowledge or experience, you'll probably die of electric shock if you don't die from the RF burns.
mostly bananas I've found, as the fruit decays the aura condensentrates and occasionally will produce fruit flies. it's really quite a mystery, I think that's where maggots come from as well, only they require a substrate of raw beef. somebody called it spontaneous generation.
When we have fruit flies in our kitchen I take a small glass bowl, put a small piece of fruit in it, cover it tight with plastic wrap, often with a rubber band, and poke a small hole in it with the tip of a pencil. A day later, the fruit flies found a way in but are too dumb to find their way out. To reset the trap or another day, I microwave it for about 10 seconds and the fruit flies die. But now I know for sure it's not because of the microwaves but because of the steam created from the heated fruit. Thanks Cody!
Consider, can the universe be justifiably called infinite? Doubtful. The universe may not have a discernible end, but it had a beginning, and its component parts certainly have a cosmological shelf life. Splitting hairs or not, if history tells us anything, it is that scientists make very poor poets. Were all just a ship of fools, heedless of what really underwrites natural law.
I don't understand the animosity towards those who care about the wellbeing of others. Fruit flies do have brains, which is evidence enough to suggest they are most likely sentient. Harming beings that you easily overpower does not make you tough. Speaking up against the mistreatment of animals in a society that doesn't want to listen takes courage.
this video deserves so many more views and likes. I learned alot about microwaves and waves in general. the point you made about how small visible light waves are i assume explains why we need electron microscopes to see very small things... you can't use an optic microscope because some of the thing you are looking at are so small, visible light can't hit them (like the microwaves at the flies) and if they can't be hit, they can't bounce back and they can't be seen..... I never thought about it like that before
Cody! Sorry, but this video is talking about the sizes of the objects compared to the wavelength of light, and that's only part of what matters here! What matters is that the vibrations of the water molecules as resonant with the microwave frequency (and of course water molecules are in both grapes and flies - and are also much smaller than the wavelength). The conductive effects are obviously huge in the grapes, but the water molecules' heating is the reason for the microwave's tuned frequency. Even if the dipoles are much smaller than the wavelength of light, they still flip back and forth at 2.45GHz in the locally DC field that they experience. If the grape wasn't full of ions it would still heat up, just a bit slower - and your flies also heated up; just not enough to kill them at first :)
If your statement is true (I don't understand the physics), then the reason the fruit-flies survive must be due their high surface to volume ratio, and hence ability to shed heat quickly. A revised experimental protocol could clarify this.
Surface area to volume ratio would assist in heat dissipation, but it really has more to do with their much smaller cross sectional length, meaning, not all the radiation is absorbed as is likely the case with the grapes. This occurs as microwave ovens are turned slight lower then the peak rotational frequency of water. By doing so, it allows better penetration of the incoming radiation and more even heating of the food. Having a thinner object mean less radiation absorbed and therefore less heating. Cody is a undergrad geologist so he can be excused...
Thanks, I was trying to get to this answer. If all the microwaves were absorbed by the outer layer of food, you would get burned surface and very uneven cooking! P.S. When I studied physics, microwaves hadn't been invented yet, LOL!
Cody I noticed that you confuse absorption with diffusion: the dust in your mine does not absorb visible light but it diffuses it because the size of the particles are comparable with it's wavelength. Speaking of the glass it cannot absorb microwaves because it's not polar, in fact any polar molecule can absorb microwaves (like oil).
Oils are NOT polar.. their comparatively large molecule chain size and inability to arrange too neatly due to high amounts of carbon double-bonds just exhibit strong inter-molecular attraction. To make an oil polar, you must saponify it (turn it into soap). Nile Red has made an excellent video on the subject. In the form of an oil, glycerol has no polar components due to loss of the hydrogen you're thinking of, due to the participation in an ester bond - which is a non-polar functional group but which readily forms a momentary dipole, causing it to have relatively high chemical activity with polar molecules such as hydroxides. + Microwaves in the 2.4GHz region used by a microwave oven only excite and absorb into water.. they do so readily, and the excessive molecular vibration experienced by the water is then passed on into surrounding molecules as heat due to the action of entropy of a system - see the laws of thermodynamics.
Rachel Mant put some olive oil in a glass and put it in a microwave if you don't believe me. The polarity of the esther groups is enough to let the molecule absorb some microwaves
As you have mass, you could not travel at the speed of light so the question is moot. And even if you could (which you can't) you could not experience anything as time would stop for you.
for you the light would have a speed of c, ie it would look the same. an outside observer would observe you traveling an infinite distance before you even flicked the light on.
Kyle did a pretty cool explanation of what it would look like to travel at light speed on Because Science. TLDW is that stars shift to blue>UV>invisible, and the cosmic microwaves shift into the visible spectrum as a hazy blue cone of light. th-cam.com/video/ZlHYsFoJ4iY/w-d-xo.html
I'm actually supposed to know all of this stuff being an EE major, and for the most part I think I do, but even so, it's obvious Cody payed waaaay more attention in Physics class than I did. Good stuff man.
Waveguide cover looks a little burned. Microwaves operate at 2450 MHz. They emit radiation with a wavelength around 4.7 inches. The holes in the mesh of the door are usually around 2 millimeters in diameter. Since the holes are very small compared to the wavelength of the microwaves, little radiation leaks out, but if you replace it with that 1/4" metal screening, you can bet more radiation will leak out.
But the odd stray microwave isn't overly dangerous. I mean if you stand right next to it, you might get a little bit warm-ish. But they are really just smaller radio waves and have the same potential to cause things like cancer as radio, which is none. I think when microwaves were invented they did the handy little ovens a disservice using the word radiation in describing how it cooks. I know back then atomic power and radiation were buzz words for the time and people wanted to be part of the atomic age. But nowadays people hear radiation and get triggered. They fail to understand that electromagnetic radiation, with a wavelength longer than ultra violet light is too big to cause damage to cells and trigger cancer. How many people would listen to radio if they knew the signal was transmitted by radio wave radiation? Would they have Wifi in their house? That's transmitting radio wave radiation!!!
And thats where you're wrong. Transmission does not increase until you are getting really close (within 5%) to the used wavelength. 1/4" is just as intransparent as 1/40" mesh. So I take on your bet. ez money.
Low intensity microwaves really aren't dangerous. WiFi operates at 2.4GHz (i.e. microwave frequencies!), so all our houses are full of them. I did experiments at school (just a few years ago, so not even in the era before health and safety) with a directed microwave transmitter and was just told 'don't look into it for too long' :D
I think you are in principal correct though (though reading this nearly made me vomit - using inches is bad enough, but mixing it with metric measurements is unforgivable :P ). Though to an engineer the two hole sizes are basically equivalent (and this is where I think you're overestimating the amount of radiation that leaks out in the latter case), to a physicist, nothing is ever as cut and dried as that. Though I'm struggling to recall the details, despite having sat an exam in electromagnetism a few months ago! (I'm studying physics at uni) In general with waves, things happen continuously and there isn't some critical hole size that will start letting radiation through.
No shit, anyone with the audio or subtitles on knows what he said. If you're concerned about the accuracy of the subtitles, then make a contribution to them.
I came here expecting anger and annoyance at fruit flies everywhere, instead I got science and education. Once again Cody you do the internet, TH-cam and yourself proud.
As soon as you got the grape out I got excited. Then you cut it in half and I got even more excited. Then you put it under the jar and I cheered. Then you turned on the microwave and I was disappointed.
Good thing he didn't use some kind of green grasshopper, huh guys? Would be really sadistic to explode him in such cruel way, fortunately our boy Cody would never even have such horrifying idea!
alcatel995channel Isn't it strange how we're fine with fruit flies but not a grasshopper. They're on the same level when it comes to self awareness/consciousness, which is zero. Just one is bigger than the other and we can see it's facial features better, so project some very human experiences and feelings to it easier (anthropomorphise?).
The only reason consciousness makes a difference is because people have more empathy for what they relate to more. Thats right; people's empathy is the only thing you are really defending with animal rights.
Melody When it boils right down to it, everything anyone does is for themselves, indirectly or not. Giving a gift to someone you (not you specifically) love, to make them happy - it's because you want to see them be happier, it makes you feel better. It's not really practical or easy to operate from that perspective though. Anyway, I would never discourage empathy, even if its misdirected. We, as a species, need plenty more of it!
This makes me wonder if microwaves are over engineered like you said or is it more of a how the public views the microwave. For example you have 2 microwaves side by side. One has the normal 1-2mm holes or what ever size they are and the one next to it has 2.5cm. Which one do you think people for "feel" safer using and therefore buy. Like you said they both have the same performance and protection but someone who knows nothing about how the magic of microwave ovens work I think people would buy the smaller hole one.
I do that all the time, most embarrassingly on a recent philip defranko video where I commented basically "Felix should have just cut out the swear" and then I went off to film this video before coming back to it and my comment was on the top with hundreds of replies saying "but it was a live stream!" turns out in the part of the video I didn't watch it was mentioned that he couldn't have cut it out.
+Cody'sLab Maybe they'll come out with a setup that adds a delay, for just this reason. It's always a bit off anyways, so a few more seconds grace could help. Push a button, and the last second of your video drops audio and gets blurry. Great for if you accidentally dox someone, too.
Fruit flies inside a glass jar, inside a microwave, inside cody's house, inside the earth atmosphere, inside the solar system, inside the milkyway, inside the universe.
I've been avoiding watching this video for 3 days because I didn't think I could handle the gruesomeness of slowly exploding insects. I'm glad I watched. Good science and no insects died!
I know this comment will get completely lost, but ElectroMagnetic radiation does NOT propagate by the changing B-field causing a changing E-field which again causes a changing B-field, etc. If it did work like this, the E and B fields would have to be 180° out of phase, which does NOT happen (the maximum E-field would be induced at the point of greatest CHANGE in B-field intensity. I.E. the 'peak' of the E-field would occur at the point where the B-field's zero-crossing is!)!
The E and the B field in a free EM wave are not phase-shifted. They both have their max/min amplitude at the same time.They stand perpendicular on each other though. Also this mesh you showed would not be equivalent, as the thickness of the wires that form the holes also influences the absorption strength. Shielding EM is not a matter of yes/no but a continous process.
A recent article about Faraday cages that should interest Cody, thumb up so he can see it. physicsworld.com/cws/article/news/2015/sep/15/are-faraday-cages-less-effective-than-previously-thought
can u conduct an experiment where u enlarge the mesh(at the microwave door) pore size until it actually affects things that is outside the microwave? sory if i cant express myself correctly. english is my 3rd language
I have to say, this is one of my least favorite of Cody's videos. I didn't understand the explanation and the wires moving around weren't really a help. It would have been better to show diagrams I think. But my biggest problem with the video is that Cody made about a dozen non-intuitive statements without testing any of them. For example, oil not being affected as much because it doesn't conduct elctricity well. You're telling me that if you put a tiny amount of oil in the microwave it won't heat up because it's too small? He could have tested different volumes of oil to see how size affects temperature after nuking. Same thing about glass not being affected. If you microwave glass it gets hot, right? How can he just say it's not affected? And the same for microwaves escaping. If he's going to assert that every microwave has holes 10x smaller than they need to be, he should really measure the leaking radiation with larger holes to prove it. Maybe he's right, but I'm skeptical. And the effect of microwaves bouncing around inside is not mentioned at all. I thought that was a key reason they worked, and if the bouncing doesn't affect the wavelength arguments he made, that should have been explained. Overall I'm left as skeptical as I started because he only made assertions instead of demonstrating they were true.
Also about the oil he stated the polar thing that also heats for example oil. But if you put a small drop if oil it should be pretty much unaffected. An interesting experiment would be something like quinoa, spread on a plate.. As long as they dont touch, they should stay cool
Glass along doesn't heat up in a microwave. Run the microwave empty then feel the glass turntable in the bottom of it. It'll be almost the same temperature as before.
I guessed you might have used a pinhole camera in the lamp compartment of the microwave. I wasn't expecting the full phone and a big hole punched in the side. Good results. Some of the best in-microwave footage I've seen.

My brother used to microwave bugs, now he's in an insane asylum
LOL
Shazzkid for real?
Brian Leonard nope i just made up a story for likes, the more likes i get the more self esteem i gain. So hit me up with likes please
Yes, but Cody didn't eat them.... (At least, not on camera.)
Cody, you make the best Science/Education Videos on TH-cam. Keep up the good work Cody 🙄
microwave manufacturers could use that hardware cloth if the consumer base was rational. As it is I still hear people say they won't stand in front of them while they cook, even thought they know the physics, juuuuust in case the machine somehow magically sterilises them
6:52 "... unlike another TH-camr, i'll show you" hahaha xD
Steve Mould burn!!
Who is Steve mould?
@@rustyshackelford3590 discoverer of the "mould effect"
Cody - your videos are awesome! I do have a little bit of an issue with your explanation here, though. Even RF with a wavelength much longer than an animal can indeed hurt the animal. Consider a person standing near an AM radio transmitting antenna. It is true that it needs to be stronger than if it were shorter, but not ridiculously so. I think what is more at play here is the average power per volume in the microwave, the small volume of the insects, and their surface area to volume ratio. If you have a 1kW microwave with internal dimensions 33cmx33cmx33cm, you have about 0.04m^3 physical volume. Since the microwaves do not fill the cavity evenly but instead form a standing wave, let's say that the effective volume over which the energy is distributed is only 10% of the physical volume, so 0.004m^3. This implies an average of 250kW/m^3 in the areas near the standing wave peaks. If an insect is about 1mm^3, that's 10^-9 m^3, so it would absorb only 250 microwatts. Even though the volume of the insect is tiny, its surface area is still respectable because that goes as length squared instead of cubed, so the insect is easily able to dissipate an extra 250 microwatts without rising in temperature much at all. In fact, the average energy use of an active fruit fly, as far as I can tell from Google, is about 300uW, which they dissipate without getting much hotter than their surroundings.
All of my friends have gone off line to watch this video. This is awesome...
NUKE THE FLIES!!
That is actually super interesting
Random Commenter ants will also dodge the waves.
jonah castro Hmm, neat!
jonah castro a group if ants in water create a hydrophobic raft with their bodys to stay alive go look up ants in water its cool.
I always wondered who the word 'nuke' became know with microwaves. I am sure you know, they use microwave.
That was really quite a good explanation of how microwaves interact with things and why they reflect off metal surfaces including holes. Thanks! A couple tiny issues though: the electric and magnetic fields are not 90 degrees out of phase, but oriented 90 degrees apart from each other. Also, the reflected wave is 180 degrees out of phase, not 90 degrees out of phase.
i tried this and now the flies are kicking my ass!!!!!!!!!!!!
i did this and they raped me
I did this and they chased me with 50 butcher knives
And that's why led deflects x-rays, it has such a high density! IT ALL MAKES SENSE NOW!!
I *love* the dig at Steve Mould with that "unlike other youtubers, I'm gonna show you [how to film inside a microwave]"
I overcook my questionable leftovers in the microwave to reduce the chances of getting sick.
You should explain why its not a good idea to touch a transmitting radio tower.
rf burns feels good
Mentioned this higher up. You don't even walk out onto transmission dishes (on large antennas) without them switched off (Even if they're not operating). You'll get fried.
Transmission power for mobile phone (cell phone) towers can be anything up to several kW, running on several kV. Without proper RF knowledge or experience, you'll probably die of electric shock if you don't die from the RF burns.

my question is where do fruit flies come from?
Eggs, but the real question is. What came first the Fly or the Egg, or maybe the maggot.
for real, they just seem to come out of nowhere whenever fruit happens to be out in the open.
Spontaneous generation.
Well when a mommy- fly and a daddy-fly love each other very much...
mostly bananas I've found, as the fruit decays the aura condensentrates and occasionally will produce fruit flies. it's really quite a mystery, I think that's where maggots come from as well, only they require a substrate of raw beef. somebody called it spontaneous generation.
When we have fruit flies in our kitchen I take a small glass bowl, put a small piece of fruit in it, cover it tight with plastic wrap, often with a rubber band, and poke a small hole in it with the tip of a pencil. A day later, the fruit flies found a way in but are too dumb to find their way out. To reset the trap or another day, I microwave it for about 10 seconds and the fruit flies die. But now I know for sure it's not because of the microwaves but because of the steam created from the heated fruit. Thanks Cody!
Came here expecting fruit fly carnage, left with a better understanding of electromagnetic waves.
Keep up the good work!
Now turn the microwave into a time machine.
the D-wave!
Consider, can the universe be justifiably called infinite? Doubtful. The universe may not have a discernible end, but it had a beginning, and its component parts certainly have a cosmological shelf life. Splitting hairs or not, if history tells us anything, it is that scientists make very poor poets. Were all just a ship of fools, heedless of what really underwrites natural law.
Oh great if there is a nuclear winter we are still doing to struggle with flys
flies
I know someone is going to go "OH NO WHY DID YOU KILL THOSE POOR FLIES" XD
Pigslayer 100 Dude wth you shouldnt joke about it. Those flies are living things on the planet same as us.
Don't forget that "African children could have eaten" most of what appears in this video. ^_^
Ehman At least plants dont feel pain.
OH NO WHY DID YOU KILL THOSE POOR FLIES-- hey, hold on, how are those flies still alive?!
(Did I do it right?)
I don't understand the animosity towards those who care about the wellbeing of others. Fruit flies do have brains, which is evidence enough to suggest they are most likely sentient. Harming beings that you easily overpower does not make you tough. Speaking up against the mistreatment of animals in a society that doesn't want to listen takes courage.
this video deserves so many more views and likes. I learned alot about microwaves and waves in general. the point you made about how small visible light waves are i assume explains why we need electron microscopes to see very small things... you can't use an optic microscope because some of the thing you are looking at are so small, visible light can't hit them (like the microwaves at the flies) and if they can't be hit, they can't bounce back and they can't be seen..... I never thought about it like that before
Let's just appreciate that unlike other youtubers, Cody showed us the microwave trick!
The small hole metal mesh may also be to better contain explosive food.
Flynntastic that makes sense for the side panel but the front I think is just visablity
0:30 "Opticial" "Infared"
this is really educational, thank you cody! :)
Soon as I saw the grape I knew what was up. I watched those "grape plasma" videos from back in the day.
Nice vid Cody!
I learned a heck of a lot more than what I thought I would juuuust judging by the title. Cheers, Mr. Science
Cody! Sorry, but this video is talking about the sizes of the objects compared to the wavelength of light, and that's only part of what matters here! What matters is that the vibrations of the water molecules as resonant with the microwave frequency (and of course water molecules are in both grapes and flies - and are also much smaller than the wavelength). The conductive effects are obviously huge in the grapes, but the water molecules' heating is the reason for the microwave's tuned frequency. Even if the dipoles are much smaller than the wavelength of light, they still flip back and forth at 2.45GHz in the locally DC field that they experience. If the grape wasn't full of ions it would still heat up, just a bit slower - and your flies also heated up; just not enough to kill them at first :)
If your statement is true (I don't understand the physics), then the reason the fruit-flies survive must be due their high surface to volume ratio, and hence ability to shed heat quickly. A revised experimental protocol could clarify this.
Surface area to volume ratio would assist in heat dissipation, but it really has more to do with their much smaller cross sectional length, meaning, not all the radiation is absorbed as is likely the case with the grapes. This occurs as microwave ovens are turned slight lower then the peak rotational frequency of water. By doing so, it allows better penetration of the incoming radiation and more even heating of the food. Having a thinner object mean less radiation absorbed and therefore less heating. Cody is a undergrad geologist so he can be excused...
George Burkhard this is the physics I learned tbh. And it makes more sense to me.
Thanks, I was trying to get to this answer. If all the microwaves were absorbed by the outer layer of food, you would get burned surface and very uneven cooking! P.S. When I studied physics, microwaves hadn't been invented yet, LOL!
Was looking for this comment. I'm surprised there aren't more comments like this.
Cody I noticed that you confuse absorption with diffusion: the dust in your mine does not absorb visible light but it diffuses it because the size of the particles are comparable with it's wavelength. Speaking of the glass it cannot absorb microwaves because it's not polar, in fact any polar molecule can absorb microwaves (like oil).
Oil isn't polar.
I'm talking about edible oils that are composed of an aliphatic chain and a polar part (an esther of glicerol)
Oils are NOT polar.. their comparatively large molecule chain size and inability to arrange too neatly due to high amounts of carbon double-bonds just exhibit strong inter-molecular attraction. To make an oil polar, you must saponify it (turn it into soap). Nile Red has made an excellent video on the subject.
In the form of an oil, glycerol has no polar components due to loss of the hydrogen you're thinking of, due to the participation in an ester bond - which is a non-polar functional group but which readily forms a momentary dipole, causing it to have relatively high chemical activity with polar molecules such as hydroxides.
+ Microwaves in the 2.4GHz region used by a microwave oven only excite and absorb into water.. they do so readily, and the excessive molecular vibration experienced by the water is then passed on into surrounding molecules as heat due to the action of entropy of a system - see the laws of thermodynamics.
I think he is referring to (short-chain) fatty acids, where there would definitely be some polar properties.
Rachel Mant put some olive oil in a glass and put it in a microwave if you don't believe me. The polarity of the esther groups is enough to let the molecule absorb some microwaves
What would happen if you were traveling at the exact speed of light? Would the light be still?
As you have mass, you could not travel at the speed of light so the question is moot. And even if you could (which you can't) you could not experience anything as time would stop for you.
iKentSpell the light would still be moving away from you at the speed of light. One of the things Einstein proved
Chris Kosin RELATIVITY
for you the light would have a speed of c, ie it would look the same. an outside observer would observe you traveling an infinite distance before you even flicked the light on.
Kyle did a pretty cool explanation of what it would look like to travel at light speed on Because Science.
TLDW is that stars shift to blue>UV>invisible, and the cosmic microwaves shift into the visible spectrum as a hazy blue cone of light.
th-cam.com/video/ZlHYsFoJ4iY/w-d-xo.html
Awesome experiment, and great explanation!
I'm actually supposed to know all of this stuff being an EE major, and for the most part I think I do, but even so, it's obvious Cody payed waaaay more attention in Physics class than I did. Good stuff man.
Waveguide cover looks a little burned. Microwaves operate at 2450 MHz. They emit radiation with a wavelength around 4.7 inches. The holes in the mesh of the door are
usually around 2 millimeters in diameter. Since the holes are very small compared to the wavelength of the microwaves, little radiation leaks out, but if you replace it with that 1/4" metal screening, you can bet more radiation will leak out.
But the odd stray microwave isn't overly dangerous. I mean if you stand right next to it, you might get a little bit warm-ish. But they are really just smaller radio waves and have the same potential to cause things like cancer as radio, which is none.
I think when microwaves were invented they did the handy little ovens a disservice using the word radiation in describing how it cooks. I know back then atomic power and radiation were buzz words for the time and people wanted to be part of the atomic age. But nowadays people hear radiation and get triggered. They fail to understand that electromagnetic radiation, with a wavelength longer than ultra violet light is too big to cause damage to cells and trigger cancer.
How many people would listen to radio if they knew the signal was transmitted by radio wave radiation? Would they have Wifi in their house? That's transmitting radio wave radiation!!!
And thats where you're wrong. Transmission does not increase until you are getting really close (within 5%) to the used wavelength. 1/4" is just as intransparent as 1/40" mesh. So I take on your bet. ez money.
Low intensity microwaves really aren't dangerous. WiFi operates at 2.4GHz (i.e. microwave frequencies!), so all our houses are full of them. I did experiments at school (just a few years ago, so not even in the era before health and safety) with a directed microwave transmitter and was just told 'don't look into it for too long' :D
Jeremy Stanger
Also. WiFi usually operates in the micro watt range. Waaay less than a microwave
I think you are in principal correct though (though reading this nearly made me vomit - using inches is bad enough, but mixing it with metric measurements is unforgivable :P ). Though to an engineer the two hole sizes are basically equivalent (and this is where I think you're overestimating the amount of radiation that leaks out in the latter case), to a physicist, nothing is ever as cut and dried as that. Though I'm struggling to recall the details, despite having sat an exam in electromagnetism a few months ago! (I'm studying physics at uni) In general with waves, things happen continuously and there isn't some critical hole size that will start letting radiation through.
8:35 Microwaves will go in 🎶

No shit, anyone with the audio or subtitles on knows what he said. If you're concerned about the accuracy of the subtitles, then make a contribution to them.
@@jackemled lol god damn settle down
"Too make this a little more exciting I'll cut the grape in half."
I came here expecting anger and annoyance at fruit flies everywhere, instead I got science and education. Once again Cody you do the internet, TH-cam and yourself proud.
I'm sure if you cram 50,000 fruit flies side-by-side in there, they would pop & smoke.
*_Starving Children in Africa could have eaten those flies_*
What a waste, they were all warmed up and everything.
Wow cody how could you. I study philosophy and I can tell you that grapes have feelings too.
Mike S 😂
he nuked a grasshopper but all the patreon subs said not to post it and he redid it with a grape
what so the grasshopper died for nothing?
yep grapes have wrath
Mike S lol😂
Somebody (let’s call her “Karen”) said that microwaves can kill COVID. I shared with her this video.
🤣
As soon as you got the grape out I got excited. Then you cut it in half and I got even more excited. Then you put it under the jar and I cheered. Then you turned on the microwave and I was disappointed.
I'm very happy you gave your test subjects the big squishy grape as payment. I'm sure they were satisfied.
7:12 He *literally* punched a hole in the microwave
Good thing he didn't use some kind of green grasshopper, huh guys? Would be really sadistic to explode him in such cruel way, fortunately our boy Cody would never even have such horrifying idea!
alcatel995channel Isn't it strange how we're fine with fruit flies but not a grasshopper. They're on the same level when it comes to self awareness/consciousness, which is zero. Just one is bigger than the other and we can see it's facial features better, so project some very human experiences and feelings to it easier (anthropomorphise?).
I found a grass hopper in my bathtub. I got my cat to eat it.
their level of consciousness is not zero, but okay.
The only reason consciousness makes a difference is because people have more empathy for what they relate to more. Thats right; people's empathy is the only thing you are really defending with animal rights.
Melody When it boils right down to it, everything anyone does is for themselves, indirectly or not. Giving a gift to someone you (not you specifically) love, to make them happy - it's because you want to see them be happier, it makes you feel better. It's not really practical or easy to operate from that perspective though. Anyway, I would never discourage empathy, even if its misdirected. We, as a species, need plenty more of it!
This makes me wonder if microwaves are over engineered like you said or is it more of a how the public views the microwave. For example you have 2 microwaves side by side. One has the normal 1-2mm holes or what ever size they are and the one next to it has 2.5cm. Which one do you think people for "feel" safer using and therefore buy. Like you said they both have the same performance and protection but someone who knows nothing about how the magic of microwave ovens work I think people would buy the smaller hole one.
I think it would affect sales yes. Id buy the "normal" one? Also it might cause too much interference with the outside, such as wifi
I agree. I would prefer the smaller holes one too.
In truth 99% of the population wouldn't even bother to check. I doubt having more or less holes or bigger or smaller even changes the cost.
As someone who battles each year with fruit flies, I love that you are nuking them.
OMG, you just turned those fruit flies into a breed of SUPER, HUMAN FLESH-EATING FRUIT FLIES!
Lol i watched the rest of the video then deleted my comment asking how he filmed inside the microwave.
I do that all the time, most embarrassingly on a recent philip defranko video where I commented basically "Felix should have just cut out the swear" and then I went off to film this video before coming back to it and my comment was on the top with hundreds of replies saying "but it was a live stream!" turns out in the part of the video I didn't watch it was mentioned that he couldn't have cut it out.
+Cody'sLab Maybe they'll come out with a setup that adds a delay, for just this reason. It's always a bit off anyways, so a few more seconds grace could help. Push a button, and the last second of your video drops audio and gets blurry.
Great for if you accidentally dox someone, too.
how did you get them in there?
Promised a free meal if they take part in my experiment.
I bet that meal is a half nuked grape...
The next day on the news: "Giant mutant fruit flies spotted in Utah."
Fruit flies inside a glass jar, inside a microwave, inside cody's house, inside the earth atmosphere, inside the solar system, inside the milkyway, inside the universe.
I've been avoiding watching this video for 3 days because I didn't think I could handle the gruesomeness of slowly exploding insects. I'm glad I watched. Good science and no insects died!
I know this comment will get completely lost, but ElectroMagnetic radiation does NOT propagate by the changing B-field causing a changing E-field which again causes a changing B-field, etc.
If it did work like this, the E and B fields would have to be 180° out of phase, which does NOT happen (the maximum E-field would be induced at the point of greatest CHANGE in B-field intensity. I.E. the 'peak' of the E-field would occur at the point where the B-field's zero-crossing is!)!
Whenever cody says "As you may know" I never know.
I swear!🤣
The E and the B field in a free EM wave are not phase-shifted. They both have their max/min amplitude at the same time.They stand perpendicular on each other though.
Also this mesh you showed would not be equivalent, as the thickness of the
wires that form the holes also influences the absorption strength.
Shielding EM is not a matter of yes/no but a continous process.
Interresting. Yea, I've seen some ovens to leak and many of them allowing a cell phone recieving a call
I vote Cody for science teacher of the decade. The way he describes things is absolutely awesome.
Cody, nobody can be an expert o everything. Your chemistry videos are great and many comments on to
I thoght it was "Cody's Lab" not "Jory Caron's Lab".
"a delicate living creature"
Forces them into a catastrophic death lmao where's PETA
PETA would probably do the same anyway
Look at the time of the video...
Swifters287 1337
I told you, I'm not a robot.
You're a better teacher than any I met in all the schools I went to!
i've read enough comics to know that those fruit flies now have super powers and will make all humans pay for the experiment you performed on them

A recent article about Faraday cages that should interest Cody, thumb up so he can see it.
physicsworld.com/cws/article/news/2015/sep/15/are-faraday-cages-less-effective-than-previously-thought
You taught me more about microwaves in 13 mins than my teacher in 3 years
I have been taking electricity and magnetism for the past semester and i have learned more from Cody than the actual fucking class.
can u conduct an experiment where u enlarge the mesh(at the microwave door) pore size until it actually affects things that is outside the microwave? sory if i cant express myself correctly. english is my 3rd language
I have to say, this is one of my least favorite of Cody's videos. I didn't understand the explanation and the wires moving around weren't really a help. It would have been better to show diagrams I think.
But my biggest problem with the video is that Cody made about a dozen non-intuitive statements without testing any of them. For example, oil not being affected as much because it doesn't conduct elctricity well. You're telling me that if you put a tiny amount of oil in the microwave it won't heat up because it's too small? He could have tested different volumes of oil to see how size affects temperature after nuking.
Same thing about glass not being affected. If you microwave glass it gets hot, right? How can he just say it's not affected? And the same for microwaves escaping. If he's going to assert that every microwave has holes 10x smaller than they need to be, he should really measure the leaking radiation with larger holes to prove it. Maybe he's right, but I'm skeptical.
And the effect of microwaves bouncing around inside is not mentioned at all. I thought that was a key reason they worked, and if the bouncing doesn't affect the wavelength arguments he made, that should have been explained.
Overall I'm left as skeptical as I started because he only made assertions instead of demonstrating they were true.
Maybe you should watch it again... But its a very complex subject!
Also about the oil he stated the polar thing that also heats for example oil. But if you put a small drop if oil it should be pretty much unaffected. An interesting experiment would be something like quinoa, spread on a plate.. As long as they dont touch, they should stay cool
Glass along doesn't heat up in a microwave. Run the microwave empty then feel the glass turntable in the bottom of it. It'll be almost the same temperature as before.
Can you speak English plz?
You are awesome man, thanks for all the films. Cheers from Sweden.
I learned quite a bit from your videos, so i just want to say thank you for making these kind of videos
