if liquid helium can already slip past glass then i wouldn't doubt that solid helium could just dissapear into another dimension and that's why we havent been able to do it yet
@@ADIIIIIIIIIIIIIIIIIIIIIIIIIIII I post many comments on other videos, and those comments get a few to several thousand likes or more, so no biggie. Thanks for your support!
Cody, each time I see one of your videos popping I'm wondering what crazy idea you will have come up with this time. Definitely one of my favourite YT channel. This DIY-style science is so fun and instructive.
AkwadTypo YT To add to this, a material at absolute zero would effectively violate the Heisenberg uncertainty principle, because you would know both the momentum and location of an object, based on the lack of movement and the measurable location.
i love your videos like this one. I'm an HVAC technician so all the science your using to demonstrate here is basically what I deal with on a daily basis. refrigerants are very interesting, if only they weren't so toxic though. its interesting to think that basically any gas (as in state of matter) you can find on earth can be considered a refrigerant. nitrogen, oxygen, carbon dioxide. some fridges even use butane. they all have a refrigerant classification.
"and now I'm going to turn on the vacuum, maybe kind of loud so headphones users beware... Oh that isn't so bad." *SCREAMS LOUDLY TO EXPLAIN THE PROCESS*
I thought I had a good understanding of how atmosphere affected state changes, but after seeing this I realize I absolutely do not understand thermodynamics at all. Thanks for reminding us of our proper place, Cody.
Cody you need your own tv show that someday will be rolled in classrooms on outdated flatscreens on black carts with old blue ray players, followed by the sound of every kid in the class rejoicing that they don't have to do work and get to watch someone drink cyanide
Why don't we make things out of solid oxygen? We could use solid oxygen to make cars, houses, bicycles, furniture, etc. There's such an abundance of it in our atmosphere it would be good for the environment, it doesn't require much processing or chemicals and we wouldn't have to mine it out of the ground. I might start a kickstarter for this, I think there are plenty of people who would love to get an eco-friendly bed constructed from planks of solid oxygen.
What perfect timing I was looking for a video on solid oxygen yesterday and the only video I saw on it that was decent was filmed with poor quality then boom I wake up to this. Thanks Cody
Curious: could you give a rundown of lab equipment like the vacuum chamber, pump, and dewar flasks? I'd especially love to know the best way to source such equipment, used or otherwise.
That looks surprisingly like a standard automotive air conditioning system evacuation pump. They use them to suck all the air out of your air conditioner so it won't contaminate the coolant. You can get them for cheap at Harbor Freight. Applied Science channel has the same Harbor Freight model we use. For the price you can't beat it, and you don't worry so much if it sucks in fluid or overheats. If you break it, it's not going to cost a lot to replace.
Try sticking the pump in the 'frig or freezer, w. holes cut to allow hoses & electric wires in (along with a gasket around them), to keep the pump cool or cold? Just a thought.
That would not work, as a refrigerator does not have an easy way to let off heat. So if too much heat builds up in there, it will not be very effective. This is why no one puts, for instance, their computers, inside of refrigerators, because they do not handle heat very well. And a way you can see that in everyday life is if you touch somewhere around the bottom of the door, or certain places where it tends to let off heat, you'll see those places will be quite warm. While it may not be possible to do that with a regular refrigerator, there may be a system in which you could build a refrigerator like object that has an effective heat-sink.
Cool video! I love these videos, I may not understand all the science all the time, but they are very interesting and I learn something from each of them, which is good. Keep up the great videos Cody and we will keep on watching. Many thanks, Joe
Why does putting things under vacuum cause them to freeze? I've always thought that the opposite was true. If you lower the pressure on water for example, it begins to boil at lower and lower temperatures. If you compress a gas enough, it turns into a liquid. What is the explanation for what we see in this video?
When the vapor pressure of a liquid equals the pressure of the atmosphere it is exposed to it will boil. Dropping the pressure of the liquid oxygen lowers the effective boiling temperature of the liquid and ultimately causes it to boil. Most liquids have a heat of vaporization, energy that must be put into the material to turn it from a liquid to a gas, and this energy is taken from the liquid, cooling it further. Another way of looking at it is that temperature is a measure of the kinetic energy of molecules of the material. The molecules with higher kinetic energy end up in the gas, leaving an average kinetic energy in the liquid that is much lower than it was to start, thus lowering its temperature.
Evaporation is an endothermic phase change, so as the oxygen/ nitrogen moves to the gas phase, the remaining liquid decreases in temperature until it reaches its freezing point.
Here's *some* explanation. When you put water at room temperature into a vacuum, it will begin to boil. As it does so, the very action of boiling decreases the temperature. Think of it as boiling taking energy to accomplish, and thus reducing the energy inside the water. Once the temperature is lowered sufficiently, the water will freeze. There's some youtube videos of this being done, but I'd recommend just looking at a phase diagram of water. upload.wikimedia.org/wikipedia/commons/thumb/0/08/Phase_diagram_of_water.svg/700px-Phase_diagram_of_water.svg.png Stare at that for a few minutes and it should all start to make sense :)
I think the key is that boiling =/= evaporation. Boiling means you're adding heat, evaporation is the surface particles naturally escaping. Also the gas being compressed raises the temperature. (Some gas law or other)
HF sells complete garbage, it will never hit a hard vacuum what it does pull will be so janky and slow as to be ineffective for most uses, and then it dies prematurely. You can also tell its garbage because the gauge is labeled in inches mercury. Mercury isn't a unit of pressure,.pascals are. Mercury based measurements are considered completely antiquated in the professional science realm as it is only a relative reading and applicable locally because the weight of merc varies based both on temp. and location, it also isn't useful for low pressures due to its own vapor pressure.
I once bought a pack of hacksaw blades from HF, I spent more time changing blades than I did sawing. They were literally worthless, I ended up tossing half the pack, yes free and in hand was still too high of a price.
Broski steady talkin shit when I have a yellow jacket gauge set (410a/134a) from Johnstone Supply. at $350 for this gauge set, I'm pretty sure the gauge set does not lie. as far as shit talking Harbor Freight sounds more like you used the wrong blades. obviously cheapest stuff on deck won't do the same as a northern tool, but if you go beyond the spec you need... you get away with it.
You should purify air before you freeze oxygen. I see you have plenty of liquid nitrogen around, so you can make a cold trap for removing CO2 and water vapor. Also, I'm surprised you don't have an oxygen tank. I can't be sure by how much, but LOX dissolves solid CO2 just like liquid nitrogen does.They're both nonpolar. As a matter of fact, such solution would have a depressed melting point than pure LOX because of colligative properties. So you should've gotten an even lower temperature when it solidified. :) If you use LOX only, you should get a solid at higher temperature, just try to put something sharp inside as a source of nucleation. Thanks for making this video.
All you need is oxygen dissolved in the fluid in your mitochondria so it can form water with hydrogen ions and electrons from the electron transport chain and keep your electron transport chain working. The oxygen in your body isn't in liquid or gaseous forms, it is either molecules of oxygen bound to haemoglobin or its molecules of oxygen floating around in your cytoplasm and ultimately the matrix of your mitochondria. We breath it as a gas mixed in with air so it can diffuse across the alveolar membranes and into our blood, liquid oxygen wouldn't be able to cross that membrane and would freeze and kill the tissue in your lungs. So yes, respiration needs oxygen to carry electrons, and its irrelevant how you supply that oxygen, but no there is no way to get liquid oxygen to cross cell membranes without the contact with something so cold instantly freezing the cell itself.
honestly I would say it depends, if you were able to compress it and turn it into a gas then yes, though if it was just liquid oxygen it would have to be an extremophile. (I think that's what they are called) Bacteria that live is the most extreme of environments
no Cody, you are truly a scientist at heart. Constructing mines looking for ores, refining minerals out of common materials, testing the strength of light; this constitutes you as a scientist in my books man. Keep up the good work!
10:00 "I'm sure he still had explosions" Yes he did, he lost several assistants that way (not all deaths but injuries for sure), the glass vacuums exploded shooting shards into peoples faces.
the phase of a material depends on both it's pressure and temperature. if you look at phase diagrams the triple point is the intersection of the sublimation, evaporation, and freezing curves
Can't find decent picture or video about it Anyway, if you got some information about a PhD about micro-structural / structural and petrography geology in your university I'll enjoy have some contact ;) Thanks you for your videos, they are awesome
You didn't mention in the video, but liquid oxygen has the nice pale blue colour just visible as your's starts to solidify. In my lab we have to check for that colour if a lot of air has gone through our cryotraps, as it would be collected alongside flammable solvents and pose a detonation risk on warming. I guess metallic oxygen would require a diamond press to make?
LOX would boil off violetly as usual, and motor touching it would solidify. Mixture of LOX and such combustibles is usually a very explosive substance. For example if LOX saturates asphalt and a tool (hammer, wrench, ...) falls on it, there's a reasonably big chance of a detonation occuring. LOX, asphalt and tools are common things in airforce and rocketry, so people have to be very careful.
Cody, that is very cold! Great video. I was wondering about the magnetism of solid Oxygen. It seemed like the oxygen was piling up on the magnet as it got colder, any idea what would have happened as the Oxygen solidified? Thanks for sharing the experiment.
considering how low a temperature it has, it would likely do massive damage to any tissue it would come in contact with, not 100% certain if it would get far enough into your system to kill you before evaporating, but at that point you'd probably make you bloat and you'd have to go to the hospital...best case scenario unless it didn't get far enough to actually swallow
While at university one of my now sadly departed lecturers demonstrated the magnetic properties of oxygen by pouring liquid oxygen (nice blue colour) into a large test tube attached to a piece of string. When a magnet was brought near to the test tube it would swing towards the magnet. He used to soak digestive biscuits (cookies) in liquid oxygen and set fire to them. They would take off like Catherine wheels. He also demonstrated that by absorbing liquid oxygen into a cigarette you could smoke the entire thing with one 2 second drag.
Its rad how the oxygen just starts to immediately liquefy and turn into gas as soon as the atmospheric pressure increases. The vacuum cover begins to fog up. Too Cool !
You solidified oxygen. In your kitchen. Not going to lie, I'm impressed, I always assumed this was something you needed a laboratory full of fancy equipment to do.
Try this gas combo: Nitrogen (78%), Oxygen (21%), Argon (1%) and a mixture of random gasses. You breathe it once, you can't stop, I promise. So addicting.
Why not use pure oxygen to demonstrate? The liquid air that you used, while it does contain oxygen, also contains a large fraction of nitrogen, which we'd expect to form a slush in the mixture. How do we know that you weren't just demonstrating liquid nitrogen slush in the liquid air?
Nitrogen doesn't liquefy when in contact with liquid nitrogen, in the same way that water doesn't solidify when in contact with ice. The boiling point has to be higher, not the same.
I have learned more with you than in my chemistry class, evan if it's in french and the words aren't the same, I find you way more interesting than her!

Is it possible for organisms to perform respiration with liquid oxygen?
no since it's a liquid and too dense it has to be in air form for it to work.

All you need is oxygen dissolved in the fluid in your mitochondria so it can form water with hydrogen ions and electrons from the electron transport chain and keep your electron transport chain working. The oxygen in your body isn't in liquid or gaseous forms, it is either molecules of oxygen bound to haemoglobin or its molecules of oxygen floating around in your cytoplasm and ultimately the matrix of your mitochondria.

To humans no as pure oxygen is a deadly toxin at a far lower pressure, that the body can’t absorb
As for other organisms, can’t say

I've always wondered, Is the liquid nitrogen bouncing back and forth between states caused by the latent heat from the state change?
that might be it. though I think it has something to do with nitrogen spilling out onto the floor of the hot chamber.
Even scientist use duct tape.
And he put the vacuum pump in the fridge...
I'm just some dude fooling around in my basement. come back in a few years when I have a PHD then you can call me a scientist. ;)
***** Nah, I consider you to be a scientist because you are so smart ;). Btw, how much longer are up in college?
no Cody, you are truly a scientist at heart. Constructing mines looking for ores, refining minerals out of common materials, testing the strength of light; this constitutes you as a scientist in my books man. Keep up the good work!
The Gaming Legends But that isn't science...
Dude, how the hell do you not have well over a million subs yet?
10:00 "I'm sure he still had explosions" Yes he did, he lost several assistants that way (not all deaths but injuries for sure), the glass vacuums exploded shooting shards into peoples faces.
Hi, not a chemist here, what is a triple point?
The point of temperature and pressure where the chemical is in all three states (solid, liquid and gas) ;)
what the hell. Alright, thanks
It's a point of temperature and pressure where the element coexists in balanced solid, liquid, and gaseous form
the phase of a material depends on both it's pressure and temperature. if you look at phase diagrams the triple point is the intersection of the sublimation, evaporation, and freezing curves
It's God f***ing with our brains.
What happens if you touch Oxygen
Unicorn bite
what happened to the nitrogen at 4:12
I shined my laser on it.
it sublimated

this guy is the definition of a mad scientist. subscribed.
I always wanted to see solid oxygen 🙏
What does metalic oxygen looks like?
I hear it is red. Never seen it myself though.
Can't find decent picture or video about it
Anyway, if you got some information about a PhD about micro-structural / structural and petrography geology in your university I'll enjoy have some contact ;) Thanks you for your videos, they are awesome
You didn't mention in the video, but liquid oxygen has the nice pale blue colour just visible as your's starts to solidify. In my lab we have to check for that colour if a lot of air has gone through our cryotraps, as it would be collected alongside flammable solvents and pose a detonation risk on warming.
I guess metallic oxygen would require a diamond press to make?
There is a picture of red oxygen crystal here. www.nature.com/news/2006/060911/full/news060911-7.html
What happens if you drop liquid oxygen in a tub of motor oil?
You know I was the one that came up with that...
LOX would boil off violetly as usual, and motor touching it would solidify.
Mixture of LOX and such combustibles is usually a very explosive substance. For example if LOX saturates asphalt and a tool (hammer, wrench, ...) falls on it, there's a reasonably big chance of a detonation occuring. LOX, asphalt and tools are common things in airforce and rocketry, so people have to be very careful.
Cody, that is very cold! Great video. I was wondering about the magnetism of solid Oxygen. It seemed like the oxygen was piling up on the magnet as it got colder, any idea what would have happened as the Oxygen solidified? Thanks for sharing the experiment.
I believe the magnetic strength gets stronger as it gets colder, farther from the curie point and all that. However I am yet to test it.
Cody'sLab hey odd question but
What would happen if you were to drink liquid oxygen
considering how low a temperature it has, it would likely do massive damage to any tissue it would come in contact with, not 100% certain if it would get far enough into your system to kill you before evaporating, but at that point you'd probably make you bloat and you'd have to go to the hospital...best case scenario unless it didn't get far enough to actually swallow
While at university one of my now sadly departed lecturers demonstrated the magnetic properties of oxygen by pouring liquid oxygen (nice blue colour) into a large test tube attached to a piece of string. When a magnet was brought near to the test tube it would swing towards the magnet. He used to soak digestive biscuits (cookies) in liquid oxygen and set fire to them. They would take off like Catherine wheels. He also demonstrated that by absorbing liquid oxygen into a cigarette you could smoke the entire thing with one 2 second drag.
Its rad how the oxygen just starts to immediately liquefy and turn into gas as soon as the atmospheric pressure increases. The vacuum cover begins to fog up.
Too Cool !
You solidified oxygen. In your kitchen. Not going to lie, I'm impressed, I always assumed this was something you needed a laboratory full of fancy equipment to do.
What happens if i snort liquid oxygen?
I tried cocaine once, but i wanna try oxygen this time
isnt that part of breathing
Idk what it does, but i wanna try it.
Yolo i guess
do you mind taking a sample before i try?
DUDE OXYGEN LMAO
Try this gas combo:
Nitrogen (78%), Oxygen (21%), Argon (1%) and a mixture of random gasses.
You breathe it once, you can't stop, I promise. So addicting.
You should make some rocket fuel, just because
RIP cody
Danke herr doktor*
***** Well I guess that would be a good topic for his rocket fuel video, talking about what kinds of fuel there are ^^
I'm a doctor,
But probably not the one you're expecting
not a rockstar, jim.
Your Intros get more creative everytime
this video is trending ! congrats Cody !
That Nitrogen Freezing and Shattering was fucking amazing.
can you eat it
Probably not. You'd get frostbite and it would be extremely painful.
check the description
and Even worse, brainfreez
"It tends to do that, doesn't it".
I have no idea! Just watching this stuff makes me feel like an idiot. How do you even know all this stuff?!?
Industrial Terms: liquid oxygen = LOX ; solid oxygen = SOX
Socks
Red solid oxygen..
Red Sox
Gold liquid oxygen
goldilox
😂
Thought LOX was Los Angeles Airpo... OH... LAX.... my bad.
Imagine having oxygen-tasting ice cream
100% favorite channel ever.
Why not use pure oxygen to demonstrate? The liquid air that you used, while it does contain oxygen, also contains a large fraction of nitrogen, which we'd expect to form a slush in the mixture. How do we know that you weren't just demonstrating liquid nitrogen slush in the liquid air?
Because it took a longer time to cool and as soon as cody opened the window the oxygen turned into its liquid form again.
thom1218 you can tell from the pale blue color that it's mostly liquid oxygen. Also from the fact that it's magnetic
Nitrogen doesn't liquefy when in contact with liquid nitrogen, in the same way that water doesn't solidify when in contact with ice. The boiling point has to be higher, not the same.
thom1218 The liquid oxygen may have been contaminated with Nitrogen, but the nitrogen would have boiled off long before the oxygen froze
And it’s magnetic
can you mine oxygen in space using magnets?
maybe out near pluto
Cody'sLab Because temperature is 0k or 4k . ? and its vacuum. why specially near Pluto? weak gravity?
Y2Kvids Pluto is cold
Vaccum is cold isn't it?
vaccum has no temperature, it's nothing :)
outer space isn't cold everywhere, when facing the sun, it's even blazing hot !
Eat that solid oxygen and you will we higher than snoop lion in cali
Gotta love the abstract "Cody'sLab" at the beginning
Super neat experiment there. Good pick up on the nitrogen boiling/sublimating in keeping your pressure too high though.
TIL that oxygen is blue in color.
Cool Lab, I think your scientific reviews and verbal comments. are first class.
I have learned more with you than in my chemistry class, evan if it's in french and the words aren't the same, I find you way more interesting than her!
Prob my favorite youtube channel
Well Done!! How cool an experiment! Enjoyed the solutions you worked out!
I keep a brand of bottled water called 'Pump' in my fridge.
Cody keeps a vacuum pump in his fridge.
I wish my chemistry teacher could make chemistry look as cool as you do. Youre awesome.
Thanks, Cody. This was an excellent video. I think one of you best.
man I love this channel so much
Love your videos Cody. Keep up the awesome work.
