Making Liquid Nitrogen From Scratch!

By Brian Lemay 27 comments

Nitrogen is everywhere. It’s a fundamental building block of life. It makes up 78% of the atmosphere,
AND it’s in these tiny micro bubbles, in my Starbucks ‘Nitro-Cold Brew.’ And yes, this episode is sponsored
by Starbucks. They challenged me to liquify
nitrogen out of the air, and that’s what I’m gonna be doing in this video. But first I’m gonna try Nitro Cold Brew
for the first time… [Drinking the nitro cold brew] Mmmm It’s subtly sweet without having to add sugar, and obviously it’s cold and frothy, and I’m gonna explain why nitrogen
makes this possible. But first I’m gonna try to liquify some nitrogen for myself out of this atmosphere. Come on, let’s go. Okay, in order to make liquid nitrogen, we need a way to make the air really cold. And to do that, I’m going to use this cryo-cooler. So essentially what’s inside here is a
cylinder of helium and a couple pistons. There’s a piston that compresses
the helium down into this section, and when it does that, it makes that gas really hot. And so, that heat gets ejected to
the surroundings through this heat sink. Then the helium is expanded down in here,
and as that happens, it gets really cold. So it absorbs the heat from the surroundings. So this is the part of the cryo-cooler
that is going to get down to less than -200°C. So cryogenic temperatures. This is the place where we can really
liquify some gas. So, I want to put this to the test and first do a sort of simple proof-of-concept and make sure that this is working and just try to liquify air, liquify the air in this room. This is Allen Pan. Allen is handier with tools than I am, so uuh, I brought him here to help me make
this happen. How should people know you, Allen? Like what do you get into, what’s your thing? Allen: I’m a failed Mythbuster, and also I have a YouTube channel called
“Sufficiently Advanced”. Derek VO: You may know Allen from
his creations and, relevant to this project, shooting
liquid nitrogen from his hands. [Allen laughs] Allen: I’m definitely breaking your drill by the way>D: I see that 🙂 I see that.Allen: It’s like a whole-I hear something!

I think there's a cryogenic thing in my A/C system, hold on I'm looking for my hammer.

The Mythbusters are failed mythbusters also.

Not sure how much a cryocooler costs, but you can buy 20 liters of LN for about $60.

Wow he's getting kinda fluffy as time goes on… maybe lay off of the mocha lattes bud.

That membrane is how oxygen concentrates work, except they toss out the nitrogen and use the removed oxygen. Keep flammables away from those vent ports. The 2nd most abundant gas in air is Oxygen.

anyone else think he was drinking guinness to start with?

Everytime i see LIQ oxygen source burn I think of the Apollo crew Grissom -white and chappy 😢

Why did you blur out your copy of The Skeptic's Guide to the Universe?

my mate had this 5 stage radial air compressor.

i was pissed off to find he had sold it.

you can do it with compressed air.

why go through all the effort to filter the nitrogen when you can just use the liquid air instead?

Is there a way to make the oxygen nitrogen safe to drink? Im not scientist and this may a dumb question but I cant help but think about this being a substitute for droughts or even be able to sustain life. Even if it is possible then I cant help but think about this being abused and taking oxygen away from the atmosphere because we tend to abuse everything (fossil fuels) and destroy our planet. Absolutely love your series best of luck.

Sponsored by Starbucks?!? Think about it!

That is way too much cold brew

Looks like Guinness.

Cool it with the betting on inconsequential things. It really distracts from the show.

Alternative title: Derek drinking Starbucks but it’s actually a Guinness.

I have always loved Nitro cold brew.

Looks like a pint of draught Guinness. The bubbles go down in that too.

When you said you would make liquid nitrogen from scratch you weren't kidding. It takes a lot of scratch to get all the equipment you used.

Damn you Starbucks for making coffee that looks like Guinness. How am I going to get drunk off this? By the way the rest of the video is great.

what if it spill on you hand i would be nice i you showed safely handling nitrogen, so that viewers wont be attempting or know the precautions to be taken , but this was realy good, and thanks for this video
