@@putridhalo7927 Hey....

Hey

lol

hey

Suddenly molecules are randomly leaving the space-time continuum :(

Federico Spadone hopefully the last time Cody works on removing gravity. I fear he may be completely successful if he put his mind to it!

+Federico Spadone My instant reaction was: "Cody, no, please don't do that. Stop removing gravity."

Not again :( that's the third time this week

Those were the shots that went wrong for this video. The first time he forgot to turn on his camera, the second time he did but the camera died just before he removed gravity, the third time is the one you see in the video. ;)

....... I didn't realize I was watching such an old video-

although the device is really cool and the idea to make it was great there are a number of simulations a teacher could pull up on the net that show the phenomena much more accurately and allow for inputs and outputs ect. so this probably isn't a good teaching tool in actuality, it's just a really cool, novel idea.

@@thecosgrove That would be a much better argument if this wasn't a horrifically inaccurate model. Gases don't act like this at all. It's an okay model for a solid, but it's not a gas. Gases are typified by minimal interaction while magnets obviously repel each other quite strongly.

I think watch all of his videos...

@@Mezmorizorz shut up. Cody has thousands of followers and is a real scientific. What are you exactly? Have you followers and your own patreon where u get paid just foar being awesum? Uh, no... No u don't.

Was thinking the same thing its 2d representation of particles

Demonstration should be accurate. This one isn't.

neither is Newtonian psychics but its good enough to get the job done ...

@@quantustremorestfuturus5434 I don't believe KZfaq is a scholarly medium for people studying physics. Its simple, and it makes sense, and it helps people learn. So stahp itttt

Right! I understand how you feel.

@@quantustremorestfuturus5434 But „analogy” and „models” don't have to...

Probably, the most awesome thing I have ever seen on KZfaq, honestly, from the bottom of my heart!!! Nice job, Cody!!!!!!!

Put it on Indiegogo, and every school that sees this video will want this in their Chemistry/Science Class Room. This is so good I can't stop admiring your success, and achievement.

Woah dud

If it doesn't involve a book or a test sheet schools won't care. Sad but true.

Some time before, Vertasium (Derek Muller, Ph.D.), another science KZfaqr launched a Kickstarter campaign for the atomic-bonding education kit called Snatoms (kck.st/1LamySr ). That was pretty good at the time, and it raised Half a Million Dollars but your new concepts/ideas/approach to educating kids of chemistry is so good, Derek's one now becomes Meh! Please, register for a patent, trust me, this will be huge!!!

gravity here can be seen as is linear pressure from top direction, it compresses the gas, the pressure is acutally lesser distance between molecules and when he removes "gravity"-pressure one can notice, that the gas flows out of the pressure tank because it was still compressed even tho we had no gravity any more, the container must have been pressurised already! and how could we possibly have created that pressure? well, he filled up the container while it was under pressure (he did this naturally) because it was standing and not flat. Just like you refill your ligther with gas, using the gas molecules and some pressure to make it flow. just like the magnets want to exit the valve, so does the gas in the ligther tada!

it would irl, too. Also the outside was a vacuum

@@kingminceraft9487 And this shows why the flat Earth people are wrong about how the gas would just go out into the vacuum. Of course we all know that the moon is fake. It's how the man gets over on us all.

False LuL

Axelios the magnets get weaker over time so in like a week they would be useless

The Champ what are you talking about? theyre neodymium magnets, there wouldnt be any measurable difference after a week

@@hughsl3942 There would be a difference in a week if we moved the experimental apparatus into an operating furnace. 😉

I suggest an electromagnet. You could easily keep reversing the poles on that extremely quickly. Adjustable frequency to simulate temperature maybe.

@@sushimrexx that would be the smart and elegant solution. Alternatively, strap a big magnet to a drill bit lol

Bamboozled again

You must be new here

yep it was fun too right...what the fuck are teachers in school doing wrong...

it is fun cause you watched it of your own free will without having to try to force your brain to learn it for the next upcoming exam/test

Manic Morzan Teacher need to be properly paid and trained

NightHawkInLight my thought exactly

NightHawkInLight I hope that knife was aluminum

Yeah a bit of an oversight on my part, fortunately the knife tends to stick to the magnet flat edge on so it would have pinched rather than cut.

Play music through a large electromagnet to visually show the speed of sound!

+Cody'sLab ok

When I go up I get high

😂

Galilean thermometer or world's smallest airship? :P This thing's free-floating after all. Not in liquid.

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.

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...

SandPox i remember him saying something about him removing it. Cause it was causing medical problems. Idk I just remember seeing something like that

SandPox those magnets might even start losing their power soon they tend to not hold up very well over time

Gregory Smith you are correct he removed the magnet in his finger.

He did, but there's a fragment left, just enough to sense the magnets

cap10h Or a science project.

Good for a basic physics lesson indeed

dayum!

Good observation, Cody musta missed it!

Exactly, what do you mean "again"??? Please show us when it exploded!

Yeah, I heard that too.

whoah guys, the obvious squad is here to dismiss the original comment

Jeffrey C this comment made me realize it's modeling gas and not glass lmfao I read the same

I was legit about to comment "that's what it says, though" because I clicked on it to see why "modeling glass with magnets" was trending lmao

Same!

Holy shit this made me realize it

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.

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.

MarsBar great idea!

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.

I try :)

Cody'sLab hello cody

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?

vape nation \//\

Attach that magnet to a motor and spin around outside. What a freakin neat apparatus; Ideas are flowing; I want one.

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.

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?

lmao, nice one

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.

Thank you!

yes similar to gravitational falloff I would assume, the inverse square law.

Gravity is inverse squared while magnetism is inverse cubed.

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.

Yes please.

cyprex he already showed them in another video a little while back. they all died :(

Agam Sandhu this might be a new batch.

Cole Weber same

Your mom was real or not.

They changed pitch during the video, did you notice?

Sienna Noelle lmao 😂

Sienna Noelle snaaam together.

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

Hey dude I didn't know u watched codys lab

They are.

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.

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.

Piano Roots Music why would he do that when he can Trojan horse education on people here on KZfaq, where they'll actually be invested in it and be more likely to actually take it to heart

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
