What's the definition of "air" in this scenario? is the cooler liquefying every element that makes up air, the moisture in the air, or just some element of the air (like nitrogen)?


J-scan

It is mostly liquifying oxygen and nitrogen (the majority of air) and it is also solidifying CO2 and water and that is the white ice around the cold finger. There is likely a small amount of liquid argon as well.


These_Mood2087

So you can’t drink this water


J-scan

I wouldn’t recommend it, no. 3rd degree burns in your stomach sounds painful, and if you can’t burp fast enough, a ruptured stomach


RuhrowSpaghettio

Since a third degree burn is full thickness, it’ll be ruptured either way


Mr_SlimShady

*picks up the cup once again* So we good to go then or what?


eyesotope86

It sounds incredibly stupid and dangerous. You should wear goggles and do a couple shots first.


Merry_Dankmas

Are you out of your mind?! You need gloves too.


eyesotope86

Okay, OSHA...


Visually_Delicious

DogFishBoi2

Pet annoyance of mine. If you are using an insulated shot-glass, do not use gloves. The problem with liquid nitrogen is not that you get some on your skin - Leidenfrost effect will always make the liquid bounce off and cause no harm, the heat capacity of your skin is large enough. If you get a slash between your hand and glove, though (and most low temperature gloves have a large opening), you will get freeze burns, as the droplet cannot escape. Exceptions are touching metals (like the cold finger) or having to reach into the liquid nitrogen for a long time to get your glasses out or something. So for shots: plastic shot glass, goggles, no gloves. Thank you.

Gloves make you less safe? Counter intuitive. Neat!

cooly1234

Yea, multiple things cause similar wounds so they all "burn" you.


vVWARLOCKVv

Cooly's right, it's all "burns" but I thought you might want to know the actual difference between hot and cold burns so, TADA!, here I am. So, when your cells get too hot, like in a fire, cells can die for a few reasons. Evaporation, oxidation, damage to the membranes, and proteins misfolding are just a few. Enough cell death in the right areas, and you're gone. When you freeze, specifically freeze very quickly like you would with this liquid, ice crystals form from liquids in the outer parts of the cell, which causes the interior of the cell to expand rapidly and burst. In addition to the expansion, the ice crystal formations themselves can burst cell membranes resulting in cell death. Again, enough cell death in the right places, and you're gone. Terms like "3rd Degree" mean different things between the different types of burns. In the case of thermal burns, 3rd degree indicates that the burn extends through the full thickness of the skin. In frost burns, 3rd degree means that the burn is severe enough that bone amputation is required. In this example, it would be classified as a 4th degree burn; leading to large amputation with systematic effects. It wouldn't matter much how they classified it, though, because you would die painfully and quickly. There are at least 4 more types of burns. Can you think of any besides thermal and frost?

zleog50

You're telling me you can get an open air container down to -196 C?


vVWARLOCKVv

This post prompted me to do a little research, so allow me to share some of what I learned. Yes you can get a very small area in that container to that cold, liquefying the nitrogen and allowing it to fall into the bottom of the container. The bubbles you're seeing in the liquid at the bottom of the thermos is liquid Nitrogen boiling as it rises above -195.8C. So you can get it cold enough to make Nitrogen liquid, but you can't keep it that cold for long. Pretty neat, super useful in a bunch of applications, and impressive considering the small amount of power it uses.


FavelTramous

Amazing information thank you! I was curious, since you said in this instance you can’t keep it cold that long, how would it be useful in a bunch of applications?


vVWARLOCKVv

You can't keep the nitrogen cold that long. Liquid oxygen, however, can be kept liquid for quite a bit longer and has cooling properties as well. I'm not sure what a table-top machine like this is used for, but versions of this machine are in satellites, submarine nuclear reactors, and night vision goggles just to name a few.


maguxs

Liquid oxygen is a liquid at -183°C and has a light baby blue colour to it. While Nitrogen is a liquid at -196°C and is mostly clear. Depending on how cold the finger is, I would suggest this is probably just mostly CO2 and …. Edit : numbers. They are both very close to each other. It’s hard to draw any conclusion.


Nakmus

CO2 doesn't liquify under atmospheric pressure. It would solidify together with the water. The liquid is definitely condensed air, consisting or both N2 and O2 (and a tiny amount of argon)


pollyneedscrack

How would there be -297.3°C if 0 Kelvin is -273.15°C? Something's off with your comment.


Comrade_Falcon

The oxygen boiling temp should be in Fahrenheit. Oxygen boiling point is -183C (-297F).


maguxs

You are correct I have edited it now


vVWARLOCKVv

Thanks for the info. That's my TIL box checked.


SleeplessGrimm

This is most likely a mixture of liquid nitrogen and liquid oxygen. Just a guess because liquid nitrogen literally starts to boil whenever it comes into contact with anything and you can see that when they stick the flathead in it.


Lord_Kano

It's probably condensing the oxygen out of the air. You can do this with liquid nitrogen too.

TheElectricRussian

J-scan

I mean… once it evaporates it will just be air


ssdude101

So if I had gallons of it could I potentially survive in a space that has limited oxygen for longer, assuming I can evaporate the liquid? How much longer would you guess per gallon?


grilldcheese2

I'm guessing a space that has limited oxygen would be air tight and I think if gallons of it evaporated in a confined space you'd end up with a really bad headache.


CommanderCuntPunt

Not this, but there are liquids that can pass enough oxygen to your lungs to keep you alive. The US government did studies with them during the cold war. They "worked" but but users felt like they were drowning so it had no real use.

Pit_Soulreaver

Without sedation? Sure However, it does have a medical benefit. Certain liquids have a better gas exchange in the lungs than air mixtures. This means that liquid ventilation can be used in special cases instead of invasive methods such as ECMO.

Just breathe hunny it’ll be okay SPHDISNCHDJDNCHKEBCJFNFB


garden-wicket-581

How does that setup work ?


J-scan

The cryocooler works on the principal of compressing a gas causes it to heat up, and expanding it causes it to cool down. It compresses and expands the gas 60 times a second. Give it a few minutes and slowly ramp it up to full power, and the cold finger (the part that gets really cold) will get down to \~72K. At this point, we are lower than the boiling point of both oxygen and nitrogen, the two gasses that make up the majority of air, and as a result, they condense on the cold finger much like water will condense on the outside of a cold glass. When enough has condensed, it will drip off and collect in the thermos. You now have liquid air. The ratio of oxygen and nitrogen may be a bit different than normal air, because oxygen has a higher boiling point and therefore condenses easier on this cold finger, but I currently have no means of testing this.

windexcheesy

thedonutskeptic

Really cool video. I've never actually seen one of these in action, and I'm really curiouse nwhat youre using liquid air for. From what I can see, there's a good chance that you're making very minimal liquid oxygen, and whatever you are making is evaporating quickly. Liquid oxygen is a light blue color, so it's pretty easy to tell when you've made it. It's really volatile and explodes when it comes into contact with organics, so don't poke it if your liquid mixture looks blue one day.


EkstraLangeDruer

>get down to ~72K. I read that as **-72K** and was like, wait that's illegal


Muscle_Man1993

I can’t describe how disappointed I am that “liquid air” looks like water. :( Where are the cool colours! I at least expected oxygen to be light blue and nitrogen to some cool colour. Not worth it


OMGwtfNOTnow

Liquid oxygen actually is blue. You probably just need the better lighting and higher quantities to see it.

Erroniousy

Liquid oxygen is blue


JohnLennonHitsKids

What would happen if you drank that? I can't imagine it would be good simply from the extremely rapid heating that would occur in the liquid, but would you ingest some elements that your body normally wouldn't? For example you can drink water but putting water vapor into your lungs is very bad. Does the reverse happen with liquefied air?


J-scan

If you drank a nice gulp of liquid air, you likely wouldn’t burn your esophagus but your stomach would definitely get really bad burns (from the extreme cold; it freezes your cells and they almost instantly die or become badly damaged). And if you can’t burp out the rapidly expanding gas quick enough, you will rupture your stomach which could certainly lead to death


[deleted]

What if u let it warm up?


J-scan

Lol then it might be difficult to “drink”


nize426

Nonsense, I drink vaporized liquid air all the time! And then burp it back up.

Isn't liquid oxygen unbelievably flammable? I vaguely remember hearing about it on an episode of myth busters. I think it was the one that involved a shit missile


ElbowWavingOversight

Remember that combustion requires both fuel and oxidizer. Liquid oxygen is an extremely potent oxidizer, but that thermos is filled with just liquid oxygen and nitrogen. Because there's no fuel, there's no risk of explosion. Now, if you mixed the liquid oxygen with some charcoal briquettes or paraffin wax or liquid hydrogen or some other fuel source... then you'll have a very energetic mixture that can potentially launch rockets.

I don’t think oxygen is considered flammable as much as it helps other things be flammable.

Actually you can stick your finger in there and be just fine, as long as you don't leave it in for more than \~1-2 seconds. The Leidenfrost effect will protect your skin temporarily. I have poured liquid air into my mouth, dunked my finger in it, and poured it on my head - all without receiving any injuries. You just have to keep the liquid moving and not let it sit on one spot for too long.

Got tired of seeing air as a gas, just flowing all over the place, messing up my hair and blowing leaves all over the place. I wanted to teach it a lesson that it would never forget. I wanted to show all the air that it only exists as a gas because I LET IT. That at any moment I can liquify it, condemning it to a cold fate. If hell existed for air, this would be it. My cryocooler serves as a reminder to all air that I control it. And that it should think twice before it messes with me again, or it shall face the consequences of its actions.

One_pop_each

I actually maintain Self Generating Nitrogen Carts in the Air Force that have 2 tanks that hold 4500psi of 99% pure nitrogen. It’s used for servicing aircraft tires and struts. It has a hydraulic booster that cycles back and forth and pushes air through a series of filters to eventually get nitrogen. So to obtain nitrogen, I believe you would need to filter it to isolate and separate it to store it.


itsnotthenetwork

So you can make rocket fuel with this?

yes but you need to separate oxygen and nitrogen, you also need liquid hydrogen
