This is a revolutionary breakthrough approach in teaching 3 basic states of matters, really. This video alone deserves a huge award of some sort for making something that some kids find it hard to understand to be phenomenally easy to understand, and I think you did a fantastic job at making this illustration.

Between 4:20 and 4:40 the molecule has achieved buoyancy. Galilean thermometer. It will never go any deeper than that because the weight of the other magnets cancel out the weight of the molecule. What an excellent way of visualizing this.
I do a lot of particle physics simulations with software. Liquid or gas or solid is pretty relative when talking about particles. They behave in very much the same way. The only difference is how strongly they bind to their neighbor particles; do they reform those bonds after they've been broken.
+Unauthorized Expression Interesting theory; my take was that it was an "artifact" of using a design of finite size, with the action at the boundary not being ideal. My thinking is, if Cody had an infinitely large glass plate, the "heavy molecule" would descend to a trivial height above the bottom.
bcubed, you sound like you know more about this than I do. I'm glad you understood that I was positing a theory not stating a fact. I *think* you are looking at this like it was a steel ball in a bucket of sand in which case the steel ball would fall all the way to the bottom and could never attain buoyancy. To be perfectly honest, I don't know why I'm so sure this is the wrong way of looking at this, but I'm sure it is. I'm looking at this like you put a drop of water in a bucket of some liquid that is lighter than water. the water is incompressible so at some point the pressure of the lighter fluid (the weight of all the fluid pressing down) will cause the water droplet to stop sinking and it will float weightless. I have no formal training in physics. I've always been interested in it and like I said I do simulation of fluid and particles for fun. These things just kind of seem right to me or they seem wrong. I typically find that my "hunches" are right for very technical reasons I don't understand.
Hey, you could be right. I just know aluminum is paramagnetic, and (looking at Cody's setup) it appears to me that the magnets directly adjacent to the aluminum bars aren't behaving "correctly"; they all remain pressed against the Al (even on the vertical sides) and don't want to move around when shaken. That's not to knock Cody, either: no "simulation" is ever perfect, and "artifacts" of the experimental setup ARE something experimental scientists have to account for.
He can sense the polarity of the magnets with his finger, I just realised haha. That's why he was able to repel 2 magnets without testing them first. The magnet in your finger really payed off XD
Andre Antunes I don't think this is the case, he only can feel the alternating magnetic field now since the piece of magnet inside his finger are too small, he know the polarity of those magnet because he pull it out from a chains of magnet so it's S-N-S-N-S-N...
Man big magnets like that cylinder you've got scare me. I couldn't stop looking at that knife on the table and thinking what may happen if you get too close. Awesome experiment though, I may make one of these to bring to bring to kids science classes.
man, ive never seen a clearer and more accurate way to simulate a gas, thats some clever shit finding the connection between magnets and atoms. Bravo my dude
What a absolutely fantastic way of explaining chemistry to people. This has got to be one of the most impressive ways of trying to get over to students the idea of how atoms and molecules react with each other.
Just imagine having this simple yet elegant way of demonstration in schools... how much better the experience would be... and how much better people would understand these concepts...
Great video... Absolutely one of the best ways I have seen someone demonstrate how gases work. I am going to share this with my sister, she teaches elementary school and I am sure the kids will love this.
Funny, cause this is the first comment I came across that Cody responded to and it's a meta comment about how active he is. Also, Cody, how are your mice?
Really hope every high school science teacher that has seen this has since made a DIY "magnetogaseoatometer". Such a great teaching tool! Pretty surprised such a product hasn't been common in classrooms for a century or more. And they're so easily made. Awesome work!
Neodymium magnets being a commodity hasn't been a thing long enough. I mean, when I was in high school, I'd heard of them, but hadn't seen one except in a hard drive I disassembled. Rare as hen's teeth. Now you can buy them from every hobby shop for relatively cheap.
If the magnets were lubricated, do you think they would shake around a bit better? Also, without any friction at all (lubricated in a vaccuum maybe?), would they actually move around more, like actual gas particles?
Best thing to do would just space the glass slightly further apart. Gas molecules vibrate and dance around. You'd have to sit it on some kind of vibrating platform.
Also I hypothesize that you can make a whole molecule sink to the bottom instead of just an atom... and if it doesn't you need to play with that effect by eliminating gravity. Spin the motor there too.
You need to use an air hockey table with little magnet pucks. You could give the pucks a good amount of mass and let everything happen nice and slow and really be able to observe and comprehend.

I want to know how magnets scale. Would a cube shaped magnet that is 2 inches across be 8x stronger than a magnet that is 1 inch across? would it be 4x stronger, 16x stronger? Thats my question. How does a magnets strength scale with its size?
most likely a logarithmic diminishing returns pattern. The larger size would give you more magnet strength, but you would be further away from the magnet field. In such systems you tend to see a logarithmic style diminishing return.
I think that in practice, you can't get much stronger than the large hockey puck magnet you can see in the video. A larger magnet would have a larger field but not much stronger on its surface.
All of the things you brought up made sense 100% and immediately. (I mean it helps that I know the info already) This physical example and level of detail and amount of material would probably take a professor an entire or several lectures, but you simplified it and condensed it into a really cool video. Thanks for sharing!
The "pressure gradient" from top to bottom is amazing. The heavier molecule sinks, but only to the depth where it can "float" in equilibrium on a sufficient amount of "air pressure". It's really interesting how the surrounding molecules slightly reorient their pattern to accommodate the heavy molecule taking up space and exerting more force. This is a genius simple concept that should be in every science class!
cool idea. thanks for sharing. might consider adding in some liquid nitrogen and see how it affects their magnetic fields as it cools down and warms back up.
does the internal resistance of a magnet affect the magnetic field? if so, i imagine gravity would start to matter less and less and the magnets would become spaced way more evenly. of course, the glass would also shatter from cooling down, heh.
Hi Cody, cool video! It would be interesting to see you sprinkle powdered metallic shavings over the glass to observe how the magnetic fields interact with each other in 3D as you compress with the "piston". :)
I like how the presentation shows the barometric effect on density. Also the hexagonal packing is interesting. The higher density of the magnets at the left and right side reflects the presence of a negative surface tension.
You should put the big magnet on a rotor to make the magnet jiggle really fast or just with some coils and pass it an alternating current through it to simulate the thermic motion
I stumbled on this channel back when cody was playing ksp. Made me want to play ksp, I then learned about the basics of orbital mechanics and DeltaV. Intrigued, I subbed to his channel and have learned so many random things that I'd probably never think to look up on my own. Keep the videos coming bro. You're making people smarter and more curious.
Amazing work, Cody. I love your mind and thoughts, they're amazing. How they're brought to the conclusions you get, I can only wish to know to be so creative. Keep up the amazing work, you're doing fantastic in entertaining and educating me and, well I could only assume, hundreds to thousands of others.
Hands down, one of the coolest videos you've done. Such a great way of demonstrating an idea! I'm sure lots will learn from this. I've always thought there could be fun things to do if you could force magnets to not flip around, but this takes the cake! Edit: I've shared on FB too. 100% of young kids going through school should be able to experience this experiment. It's just so cool.
Perfect example why mars can't hold an atmosphere on it's surface. I've always thought about if you go deep into mars is there a point where the atmosphere would be thick enough to survive without a pressure suit. I'm willing to bet it is. maybe even breathable air.
Actually, given that Mars has ~37% of Earth's gravity it could hold a thin but theoretically breathable atmosphere. However, the crucial factor is that Mars' small size allowed its molten ferronickel core to solidify, and without rotating metals it has no magnetic field. This allowed particulate radiation (i.e. mostly solar wind) to bombard the atmosphere and slowly strip it away, which is something that doesn't happen on Earth because we have an electromagnetic generator in our core creating a lovely magnetic field.
We can easily add a synthetic magnetosphere using nuclear power to fuel it. Trivial 20th century technology. Also I am pretty sure as you get closer to the center of mars, pressure will decrease and make it harder to breathe. The surface has the highest pressure.
"Easily" is an unbelievably relative term here, because you can't just "add" a synthetic magnetosphere. Not only does it take raw mass, which we do not have to provide because Mars is a very long way away and there would be practically nobody there, but also it requires a stupid amount of resources. To make a planet-sized magnetosphere you'd need a planet-sized machine because otherwise there's no way you're going to be able to maintain the thing, or even realistically fuel it. Also, as you descend into a planet you allow more and more of its atmosphere to weigh down on you. This _increases_ pressure, rather than decreasing it. Unless the laws of physics were changed when I wasn't watching, this will be true everywhere in the universe.
Great demonstration toy! And I want to really applaud the interaction with the voice from behind the camera. No cringe questions and no cringe answers. 👏 Now I keep thinking about how the magnets could be put in more realistic thermal motion... Probably a much bigger arena needed, and powerful bumpers all around, to simulate the temperature of the container. Bumpers a bit similar to those from a pinball machine...
Just to be technical, in air the speed of sound does depend on what's known as "density altitude". What we would call this thing in something other than air I'm not exactly sure.
Cody made a Video where he build a sealed bioshpere. That means he put saltwater, some algae and seamonkey eggs in the "fish tank" and sealed it afterwards. Those animals are seamonkeys which also live in the great salt lake. (Cody lives in Utah near the great salt lake)
Its a sealed ecosystem enclosed inside a glass decorative brick with plants and algae growing on the bottom and brine shrimp living of of the algae, allowing the nutrients and oxides in the water to cycle between phases and keep everything alive. All it needs is sunlight.
Yup it's another project. We'll probably get a full video on it, or at least a few minutes within another video. Often the ending clips are little previews.
This video is so awesome. Very informative for someone with a limited knowledge of chemical reactions but with enough detail for others with more knowledge. Thanks for your awesome content :-)

The problem is that the magnets are trying to turn over and align, so are jamming between the plates.
They make teflon coated magnets of all sizes. I bet if he got a bunch off those it would behave better.
In answer to OP's question, No, a liquid lubricant would not help. It's density and viscosity would just stick the magnets in place.

Hey Cody! You need to seal it and fill it with oil!

Or maybe some clear lube? Plus maybe some "heat source" by adding continuously flipping electromagnet on the sides.
What if the magnets were surrounded with a plastic ring that kept them just get enough start to prevent sticking together also?

yes similar to gravitational falloff I would assume, the inverse square law.
Gravity is inverse squared while magnetism is inverse cubed.

The "pressure gradient" from top to bottom is amazing. The heavier molecule sinks, but only to the depth where it can "float" in equilibrium on a sufficient amount of "air pressure". It's really interesting how the surrounding molecules slightly reorient their pattern to accommodate the heavy molecule taking up space and exerting more force. This is a genius simple concept that should be in every science class!
This is probably one of my favorite videos from you. Great visualization for people.
cool idea. thanks for sharing. might consider adding in some liquid nitrogen and see how it affects their magnetic fields as it cools down and warms back up.
does the internal resistance of a magnet affect the magnetic field? if so, i imagine gravity would start to matter less and less and the magnets would become spaced way more evenly.
of course, the glass would also shatter from cooling down, heh.
Not Legato yes! Temp matters greatly!
Especially as you increase till the curie point of the material
i just read up on magnet strength a little, the N ratings, yeah there are some curves about them and some of them deal with heat better etc.
he'd have to find a way to deal with the thermal shock
What a brilliant idea!
I can see frames like this standing in every chemistry/physics classroom in the future!
You really know a lot of stuff, I've studied physics and not many demonstrations were like this. Brilliant! Subscribed with no hesitation.
You are a better chemistry teacher than all of the chemistry teachers I’ve had combined
Hi Cody,
cool video!
It would be interesting to see you sprinkle powdered metallic shavings over the glass to observe how the magnetic fields interact with each other in 3D as you compress with the "piston". :)
That was a great demonstration. Good thinking. :-)
Hey dude I didn't know u watched codys lab
Wow that's a really great tool to explain the model. Awesome work. Your pedagogy just reach another level
I like how the presentation shows the barometric effect on density. Also the hexagonal packing is interesting. The higher density of the magnets at the left and right side reflects the presence of a negative surface tension.
You should put the big magnet on a rotor to make the magnet jiggle really fast or just with some coils and pass it an alternating current through it to simulate the thermic motion
They'll snaaam together
Sienna Noelle lmao 😂
Sienna Noelle snaaam together.
I stumbled on this channel back when cody was playing ksp. Made me want to play ksp, I then learned about the basics of orbital mechanics and DeltaV. Intrigued, I subbed to his channel and have learned so many random things that I'd probably never think to look up on my own. Keep the videos coming bro. You're making people smarter and more curious.
This is an excellent way to visualize molecular motion and should definitely be something used in grade schools.
Your crickets reminds me of how you can calculate the temperature based on the frequency of cricket chirp.
I hope those magnets are more attractive than me
They are.
OneToughCookie
Haha! Your profile picture is really funny.
10:16 still more attractive than me.
yea, it's so funny, where did you find it?
OneToughCookie Do you mind if I share your picture? :)
Amazing work, Cody. I love your mind and thoughts, they're amazing. How they're brought to the conclusions you get, I can only wish to know to be so creative. Keep up the amazing work, you're doing fantastic in entertaining and educating me and, well I could only assume, hundreds to thousands of others.
Hey Cody, that's such a great way of explaining molecules! Loved your video :)
This is actually kind of genius.
Thanks for this.
You could mount the big magnet to an engine, so that the random thermal motion of the particles is better simulated!!!
This is REALLY clever. And it illustrates certain aspects of molecular chemistry really well.
This video keeps me coming back every few months, it's just so satisfying
(3:30) Yeah, me too!!!
psygn0sis 😂
WOW cody, the magnets are a great idea for a lesson on the states of matter
this is so far the best way i have seen to represent molecules . very smart and creative !!
Hands down, one of the coolest videos you've done. Such a great way of demonstrating an idea! I'm sure lots will learn from this. I've always thought there could be fun things to do if you could force magnets to not flip around, but this takes the cake!
Edit: I've shared on FB too. 100% of young kids going through school should be able to experience this experiment. It's just so cool.
Perfect example why mars can't hold an atmosphere on it's surface. I've always thought about if you go deep into mars is there a point where the atmosphere would be thick enough to survive without a pressure suit. I'm willing to bet it is. maybe even breathable air.
There is no oxygen on Mars. I think what little atmosphere there is on Mars is mostly CO2.
actually there is a % of o2 on mars
Actually, given that Mars has ~37% of Earth's gravity it could hold a thin but theoretically breathable atmosphere. However, the crucial factor is that Mars' small size allowed its molten ferronickel core to solidify, and without rotating metals it has no magnetic field. This allowed particulate radiation (i.e. mostly solar wind) to bombard the atmosphere and slowly strip it away, which is something that doesn't happen on Earth because we have an electromagnetic generator in our core creating a lovely magnetic field.
We can easily add a synthetic magnetosphere using nuclear power to fuel it. Trivial 20th century technology.
Also I am pretty sure as you get closer to the center of mars, pressure will decrease and make it harder to breathe. The surface has the highest pressure.
"Easily" is an unbelievably relative term here, because you can't just "add" a synthetic magnetosphere. Not only does it take raw mass, which we do not have to provide because Mars is a very long way away and there would be practically nobody there, but also it requires a stupid amount of resources. To make a planet-sized magnetosphere you'd need a planet-sized machine because otherwise there's no way you're going to be able to maintain the thing, or even realistically fuel it.
Also, as you descend into a planet you allow more and more of its atmosphere to weigh down on you. This _increases_ pressure, rather than decreasing it. Unless the laws of physics were changed when I wasn't watching, this will be true everywhere in the universe.
In physics, it is called "Coulomb gas" (though it is "kind of" Coulomb gas as force is proportional to distance in power of four and not two)
Great demonstration toy! And I want to really applaud the interaction with the voice from behind the camera. No cringe questions and no cringe answers. 👏
Now I keep thinking about how the magnets could be put in more realistic thermal motion... Probably a much bigger arena needed, and powerful bumpers all around, to simulate the temperature of the container. Bumpers a bit similar to those from a pinball machine...
Really cool Cody!
I like so much the way you demonstrate science in practice.
Thanks for sharing so many cool experiments!
I love your channel so much plz dont ever become click bait, Thanks.
For some reason that cricket chirping makes me feel nerdy.
The world NEEDS teachers like you. Keep it up.
every freaking school needs a simulation like that. so easy and yet so useful GOOD JOB
Why did I read this as molding glass with magnets
Hahaha, me too =D
I did read it "Modeling Glass with Magnets" xD
Hahahaha.
I face palmed myself when I finally figured it out.
The whole beginning, I was like is going to freeze the gas in there?!
Hahaha
Maybe because we saw a glass panel in the thumbnail. Funny how brains work. I did the same mistake.
10k likes Some vids yea
This is exactly why I watch this channel! Not only is it entertaining, it's highly educational! Thanks Cody!
This is amazing! God bless you for taking the time to do this!
This was i think one of the most original things ive ever seen on CZcams. Awesome job Cody.
This would have made me like physics in highschool.
Just to be technical, in air the speed of sound does depend on what's known as "density altitude". What we would call this thing in something other than air I'm not exactly sure.
I'm new. What's with the clip at the end? Another project? What are they?
Cody made a Video where he build a sealed bioshpere. That means he put saltwater, some algae and seamonkey eggs in the "fish tank" and sealed it afterwards.
Those animals are seamonkeys which also live in the great salt lake. (Cody lives in Utah near the great salt lake)
Its a sealed ecosystem enclosed inside a glass decorative brick with plants and algae growing on the bottom and brine shrimp living of of the algae, allowing the nutrients and oxides in the water to cycle between phases and keep everything alive. All it needs is sunlight.
They're sea-people. Pretty soon they'll become civilized and start playing basketball and stuff.
Yup it's another project. We'll probably get a full video on it, or at least a few minutes within another video. Often the ending clips are little previews.
NOTE: The last time Cody tried that, the shrimp died, so it's nice to see a reboot of that.
This video is so awesome. Very informative for someone with a limited knowledge of chemical reactions but with enough detail for others with more knowledge.
Thanks for your awesome content :-)
Hi! I've not even watched video to the end at this point but i can already say: bravo. This needs to be as a demo in every elementary school
Cody, you need to go back to school, pick up a degree in education, and become the world's best science teacher
Piano Roots Music why would he do that when he can Trojan horse education on people here on CZcams, where they'll actually be invested in it and be more likely to actually take it to heart
Hey Cody, how's the methane generator doing?
Probably very shitty.
Boba Fett he said that it failed a while ago
it froze and all the bacteria died. I think he got all he needed from it. He also said he doesn't visit his parents house too much as of late which is where it was located
It died along with his shrimp in a box
The way you explained chemistry is impressive
This man has taught me more in 12 minutes then my teacher did in an entire school year
Damn, I really wish that you were my physics teacher.. :)
Looks like you made yourself a magnetic earthquake detector.
That was probably the best tutorial on gases and molecules I've ever seen. Thank you
LOVE IT. The model, the behavior of molecules, I knew it but I can say I just GOT IT, really beautiful playground.
