- I used a nitrogen membrane and Stirling cryocooler to liquefy nitrogen out of the air. For this video I partnered with Starbucks to celebrate their Nitro Cold Brew. Order one here: starbucks.app.link/derekmuller
Making liquid nitrogen is hard - in fact up until 150 years ago scientists doubted whether it was even possible to liquefy nitrogen. In 1823, At the royal institution in London, Michael Faraday first produced liquid chlorine, kind of accidentally by putting it under high pressure. He similarly liquefied ammonia.
Borrowing a mixture from Thilorier in France, a combination of dry ice, snow and ether, he reached a temperature of -110C. By 1845 he used this mixture plus a hand pump to pressurize gases to liquefy all the known gases except six, which included oxygen and nitrogen. These became known as the “permanent” gases.
A French Physicist Aimé compressed oxygen and nitrogen in tanks and then lowered them into the ocean over 1.6km deep, where the pressure got up to 200 atmospheres. Still the gases didn’t liquefy.
Only at the end of 1877 were the first droplets of liquid oxygen and liquid nitrogen produced, by Cailletet in France. He first tried oxygen by compressing it up to 300 atmospheres, cooled to -30C, but that wasn't even enough to liquefy oxygen. But when he suddenly released the pressure, the expanding gas cooled, he estimated to -200C and he saw a mist and then droplets slide down the walls of his vessel.
It's amazing how far we've come in that now I can purchase a helium-based cryocooler. It compresses and expands the gas to absorb heat from the tip of the cold finger and eject it into the surroundings at ambient temperature.

Thinking quickly Derek made an homemade nitrogen liquefier using only some strings, a squirrel and a nitrogen liquefier.
Exactly my thoughts
Yeah was looking for this comment. perfect haha
Well, the method I thought about is much simpler but probably less efficient
You cool down air and keep track of the temperature. When it is still a few degrees above -193°C, you maintain the temperature and remove all the liquid that forms. That will be the other gases you don't want. Get below the fusion point of N2 and there you get the precious liquid.
Anyways, it is nice to see some of the tech he used. I had never imagined a refrigerator like that existed
@@srpenguinbr The problem is that O2 has a very close boiling point so you would still liquefy it. A method more "from scratch" would maybe be like burning all the oxygen before cooling it.

“Failed Mythbuster” is one of the coolest (no pun intended) resume items - ever!
It's certainly on my resume!
So, when liquifying a gas, it is handy to place the container on a scale during the process. As the gas liquifies, it becomes more dense. More dense, but same volume = more mass. More mass in a non-inertial frame of reference (ie, a "gravity field") has more "weight". You can then check the scale during the process without disturbing the process, to see if, and how much, liquified gas you have created.
I too was wondering why they were not using a scale. Although that could be an expensive prospect. Precision scales usually don't have a very large range, and the weight of the flask/dewar/whatever might exceed the weight limit of a scale with enough precision to notice the liquefaction. The other problem of course is the seal they had to use for the nitrogen. When doing oxygen they didn't need such a seal, and the flask could just be overlapping loosely with the nozzle. But the nitrogen required a seal, and that definitely would dampen the reading on the scale.
Thinking a bit on this... they might have been able to use a simple arduino "pinger" that measures distance via ultrasonic ping, with that shooting into the flask and measuring the depth of liquid. That would only require wires leading out, and could be integrated into the seal. This might be improved by adding a "float" - a sheet of something that would float on top of liquid nitrogen, to provide a better target for the pinger or maybe a laser distance measurement tool?
The container is attached to the cooler. You need an exact scale that can handle a fairly high weight
You could have also added a balloon to the system and set the flow rate where the balloon was neither expanding nor contracting, thus matching the flow rate to the condensation rate.

How cool!
How long does the liquid nitrogen stays liquid for, before turning back into gas state?
That all depends on the pressure you’re keeping it at.
Phase changes depend on both temperature and pressure. If at atmospheric pressure, then it becomes a gas again at 77K.
As for how fast a quantity of liquid nitrogen will completely boil away, that all depends on the container and how exposed it is to that temperature.
For example putting liquid nitrogen into water will boil the nitrogen a lot faster than it simply sitting exposed to air.
When I worked at Micron semiconductors in Boise Idaho I noticed in the first few months of working there that there were people that appeared to have big purple birthmarks on their faces and arms. My buddy and I were really confused as to why that many people with the same markings could all work at the same company, then we found out they were test techs whose daily job was connecting and disconnecting liquid nitrogen lines and every once in awhile they wouldn't disconnect correctly and these guys would get blasted in the face and arms with liquid nitrogen. They all got a big settlement and were purple for a year so.

Excellent video. I love the DIY liquid nitrogen machine! 😎
Me thinks someone at Starbucks went for a pint of Guinness when they came up with this idea...
I just learned why medical fields use so much helium. I never understood how helium was used in refrigeration until now and I'm absolutely blown away. Also I'm happily supprised how well this project went.
Yup. NMR. Superconducter coils. You need very stable magnets, (sub-parts per million), so you need very stable electrical current, and the best way of getting that is to short a current into a superconducting coil. You disconnect the power, and the current just keeps going round and round. Superconducter coils need low temps, hence liquid helium. Which is sitting in a jacket of liquid nitrogen. which boils off before the helium does, keeping the helium cool and not needing refilling so much.
If you want to be more specific, the reason helium is used particularly in this application is not only because it doesn't liquify, but also because helium, being a light gas, is easier to push around making it more efficient in the cryocooler- which is actually just a stirling engine in reverse.
And we are running out, once it's gone it's gone.
@@drampadreg1386 We're nowhere near running out of helium. And it's the same with any other natural resource. Technically, we're also "running out" of iron, but are we anywhere close to excavating every single iron vein in existence, and have we tapped into every single way of getting iron? No.
@@nikkiofthevalley also in the case of many elements, we can extract them from asteroids and space rocks, which are essentially an unlimited supply of materials (and this isnt even that far fetched of a concept, its been done more than a couple of times so far, whether from meteorites or orbiting space rocks)

Short answer: if you compress air extremely (which makes it really hot, Boyle's law), and use something like water to cool the compressed air back to room temperature, and then allow it to expand back to 1 bar pressure, you should up with liquid air 😉 Air Liquide and other industrial suppliers does this on an industrial scale every day, and purifies the various gasses (nitrogen, oxygen, and argon) by allowing them to gas off at their respective boiling points. You reliquify the pure gas that evaporates, and you end up with pure liquid nitrogen, oxygen, and argon!
What other elements were in the air that was included in the liquid? Is pretty cool watching the "distillation" process to get near 100% pure nitrogen in it's liquid form, but from what I remember from our investigations in San Diego when we were younger, it takes many years to months to find an absolute zero
Starbucks nitro coffee
Guinness: Am I a joke to you?
finally, I found this comment.
I didn't know what the hell nitro coffee is but Guinness... everyone knows it.
Was finding this comment, hahahaha. I made my comment about Guinness too.
When Guinness sponsors the video they can get mentioned too.
eerh no
FYI: This advertisement was way better than the last one! Stay focused on the science and engineering side and it all works out in the end.
I love that you guys are betting on science, love it!
Derek lost the op to say "Making liquid nitrogen out of thin air"
How to make liquid nitrogen from scratch:
Step 1: Get an expensive piece of advanced engineering.
Step 2: You did it!
What he bought was essentially a pump and a tank. Expensive ones but still.
You can see that he had to put in quite a lot of effort to connect them and finding the right measurements to make them work.
@@divygutp1509 And cryocooler?

Fer Chrissakes, did you invent the computer you're whining on?
I mean, the compressor is probably more expensive than that piece of ‘engineering’
When you want your friends to think you are drinking Guinness for breakfast? ;-)
I was thinking Guinness the whole time, too! 😄
mmmm breakfast Guinness.
Except guiness is nicer and cheaper than the horrible stuff from starfucks.
When you are drinking Guinness for breakfast, but want your friends to think it's coffee ;)
"What do you do with home-made liquid nitrogen?"
"Drink up"
That's how real scientists/inventors work. It's a crazy mess, because they put together whatever they need, wherever they can, and move on with the experiment. I love that this was filmed 'in situ', and not sanitized to give a phony impression that things are all tidily set up in advance. Looking around my office here... I might be one of those guys! :)
"Making liquid nitrogen from scratch"
*Shows contraption used to make liquid nitrogen*
Scratch can mean various things. Unless you want to go Primitive Technology style you're going to use tools made by other people
yeah, it reminds me of those DIY at home videos, where only thing needed is cnc router, lathe and tig welder
@@the1exnay I do understand, and for all intensive purposes, this is a joke. But if we want to dig a little deeper, you can see that there isn't much information in the title about the method of making the liquid nitrogen, which could possibly mislead people to expect something else.
@@kazoo3354 its for all intents and purposes not intensive purposes.
@@CircumcisionIsChildAbuse Just in case someone is learning English, the "its" you used should be "it's" because it's a contraction of it + is.
Edit: Also, I'm glad that you provided the correction.
As not a fan of starbucks, there are other fluids that gain from nitrogen:
Guinness =) of course!
1_2_Die I thought that coffee was Guinness at first!
As did I, Scaredyfish. I guess he's contractually obligated not to mention anyone else's beverages during a video sponsored by Starbucks.
@@mal2ksc Of course he's contractually obligated NOT to mention any other brand.
I guess they could have asked Guinness and they would have sponsored that video too. But alcohol is BAD, you know.
Man I’m jealous, I’ve wanted a nitrogen membrane or molecular sieve for the longest time! And I’m still looking for one that’s not crazy expensive! Awesome stuff guys
did you every find one?
I'm trying to find one too
@@Splyfof No but I haven't really been looking that hard. It's not exactly a top priority, more of "if I come across it, that would be cool".
What do they typically run?
One of the best videos I've seen in years. Loved it.

Nitrogen can be used for inert gas asphyxiation. Legal in Australia and Switzerland.
Awesome. Does this also make for dry ice?
Well played, Starbucks. You got me to see your ad.
Yeah me too, but I have never been to Starbucks and I am not planning to change that - so I guess this has zero effect on me 😮
Guiness is better and also use nitrogen
@@odindimartino597 Guinness is for real men, that Starbucks crap is for soyboys.
1959 Guinness began using nitrogen and Starbucks start use this approach after 70 years)
2019 is 60 years from 1959.
@@asiandude3207 Also, starbucks has had nitro cold brew since 2016.
@@asiandude3207 Yeah 60! Damn math!
I was thinking that nitro cold brew looked so much like Guinness.....now I know why. Thanks Max, I learned something new today :D
... What's your point?
It's like saying "we discovered electricity so back in time and Tesla made use of it in this decade only smh"
It's a stirling engine, it uses a stirling engine to cool the air down. If you were to reverse the motions with heat input and cooling, you would output motion. Helium not only makes it so the fluid won't turn to liquid, but actually makes the engine itself run better because it doesn't have to push around a heavy gas.
In theory air conditioners could be made using this cooling effect.
I'm not sure if you'd have a working engine that produced electricity if you were to heat the cooling end.
I haven’t tried the nitrogen cold brew yet, but I do like Guinness’ nitrogen in their stout, and the nitrogen in Boddington’s ale. Very creamy!

"They challenged me to liquify nitrogen out of the air..."
Dude, my friends only challenge me to speak to my crush and I can't even do it
Speaking to my crush is damn more challenging than affording that cryo cooler
That’s because you’re 12.
Try liquid nitrogen, that way you get all the time you need to make your case.
That’s more challenging than understanding every aspect of a Veritasium video
Use crycooler
I was thinking about that nitrogen membrane apparatus, if it passes atmospheric nitrogen and the other gasses are emitted from the holes on the side, could you not tap those holes and attach fittings to them to carry the (mostly) oxygen at ~1 ATM to another series of cryopumps at specific temperatures so that your end products are liquid nitrogen, oxygen, argon, etc..? The first stage could be a simple R134a system at say -25C to freeze out any water vapour or air compressor lube
I work as an appliance repair tech. I don't like doing sealed system work aka dealing with other people's broken compressors, blockages ect.
However, through some reading and nerd raging I made a 3 stage "cryo cooler" I have 3 separate compressors stages that in the end produce liquid nitrogen. It uses a lot of power but produces it fast. And yes, with modifications I've made LOX.
LOX is some scary sh!t.. period. But I digress. Having liquid nitrogen to play with has been super useful as well as fun.
*I just use the heart of my ex girlfriend*
Colder than a Cryo Cooler
Yes bro!
Now I know what my Starbucks nitro brew needs!

I love how he is so considerate while he is working on this project in your home
When I was a kid I used to love when my dad took me to his work so I could play with the liquid nitrogen coolant. He used to pour some into a styrofoam recipient and I would spend my time freezing whatever I could put my hands on. Other times he would say "Let's just ruin all this equipment, son", and he would throw liquid nitrogen on all the panels in the control room (the nitrogen evaporates before it even touches anything). I remember being amazed no matter how many times he did it.
as i understand it, since the TWA 800 fuel tank explosion, they basically use one of those nitrogen tubes on the air intakes of the fuel tanks. That way the insides of the empty fuel tanks are mostly nitrogen, which would inhibit another similar explosion.
