Liquid Nitrogen Ice Cream - Short Version

[halite001]

Alternatively, you can pour LN2 into the bowl, allow it to settle and stop boiling vigorously, and add the ice cream (liquid) drop by drop, giving you dippin' dots.

[halite001]

And btw, that's too much protection for LN2. It's actually not that dangerous (assuming you don't put your hands in it). Working in a chemistry lab, I pour more liquid nitrogen daily than most people do water, and the trick is just to not wear anything that soaks. So jeans and those gloves are indeed a bad idea. If gloves are needed, there are cryogenic gloves that resist LN2 soaking.

[halite001]

Won't the LN2 freeze and kill the salmonella??

[carl95125]

Don't add eggs unless you plan on making a custard...with means you need to heat the eggs in the cream...both making the ice cream thicker and killing the Salmonella.

[Masterdude658]

oh good :) i dont wanna die :D

[kaoapts]

you can eat nitrogen

[Masterdude658]

that couldnt be edible

[agentcox]

Well, we ate it.

[WifeyChaotic]

of course it is, ive done it before.

[hesperosm198]

Its plenty edible. Nitrogen makes up 78.1% of the air we breath, its perfectly harmless.

[Supish16]

unless u stick ur head in a cloud of nitrogen, then u will asphyxiate yourself

[Terinigan]

@Masterdude658 Lol, you breath nitrogen

[natyop1]

@Masterdude658 the liquid nitrogen evaporates as soon as it touches the mixture so none actually is in the ice cream

[SailorBarsoom]

I want to do this. I do not have a dewer of my own ($600 to $900). Exactly how do I go about getting LN2?

[agentcox]

Airgas will rent you a dewar. You need to put down a deposit, and you have to cart it away in a truck. But you can rent a truck, too. That's how I did it.

[SailorBarsoom]

Thanks. I won't be able to do it today, but next time I'm throwing a party, perhaps.

[sweeteepoohie]

mehh i used it to make icecream in chem todayyy very funnnnn. but we were'nt required to wear goggles...hmmmm....i dont think anyone got hurt. but we had so much fun pouring the stuff on the lab tables. lol. it would turn to gas form sooo quicklyy. but the icecream was amazing! soo creammy sooo cold....yummmy

[Skinnoflap]

gloves are not smart unless they are tight fit. if LN gets in then it stays there on fingers.

[agentcox]

Very true! Kids, remember not to do what I do in this video. Keep the gloves off.

[starwizznyc]

Ice cream of the future, say whaaaat!

[mynamejejaka]

Why is he protecting his face, why are Americans such scary cats, and they wouldn't have to go out to do that..

[agentcox]

Think about your eyes for just a second. How useful they are - how you'd hate to lose even one of them. How it'd be to have no depth perception or, God forbid, no sight at all. Blind.

One drop of Liquid Nitrogen in your eyeball and that eyeball is gone. Your sight is gone. That eye will never work again.

You do what you want on your own time with your own eyes, Jejaka, but I'm saving mine with a ten-dollar piece of plastic.

Don't be an idiot. Wear safety goggles or a face shield.

[mynamejejaka]

If you don't remember liquid nitrogen evaporates very fast. One drop wouldn't hurt you a bit you can, try pouring nitrogen over your hand, it won't do anything. For more drops you must be really clumsy to do that.

[agentcox]

Here's the problem with your thinking on this. Liquid nitrogen boils. When it boils, it moves, you've probably seen that. As long as it doesn't stay in one place and freeze the same tissue, you won't get hurt. It's called the Ledenfrost effect.

But your eye sits in a socket. That socket is ringed by muscle tissue that makes it a tight fit. If an LN drop gets in the socket, it may stay there, because it has nowhere else to go. Then it freezes the same spot.

That spot is your eyeball.

[PKokemon]

better alive then dead retard

[SailorBarsoom]

Perhaps some day, every kitchen will have a supply of liquid nitrogen as a standard bit of kitchenry.

Hey, there was a time when nobody had a microwave oven.

[fugiboo]

You tried to make ice cream with liquid nitrogen and froze your balls. Now you can't have kids. Sad story but true.

[SailorBarsoom]

Liquid nitrogen is used to preserve sperm. So while I hope I never freeze my balls with the stuff, if I did, there'd still be a chance to save the sperm.

[CopsHateMe]

blendtec blender can make ice cream in about 3 minutes :O

[elmofir]

i work at the N.R.A.O. every once in a while we get the company together, get some liquid icecream mix and make instant icecream, the cool thing is ice cream made with liquid nitrogen is super creamy. good vid.

[agentcox]

It's -297.4 degrees. Liquid Nitrogen is colder than that: -320 degrees. The metal bowl the LN goes into is conductive, so it's definitely possible that the bowl (or at least the air right next to the LN) will chill down to -297.4 degrees, condensing liquid oxygen right from the outside air and onto the bowl.

[masterpj55]

isnt that dangerous to eat?

because there could still be some poisiones stuff in the ice cream??

[BlackSkullRacer613]

1. Nitrogen is not toxic. If it was, we'd be dead, for the atmosphere is 78% nitrogen.

2. Any nitrogen left over would evaporate into the atmosphere.

3. Salmonella bacteria would die after being exposed to subzero temperatures.

[mynamejejaka]

Bacteria dies by heat not by cold.

[agentcox]

Yes, they can die by cold. Bacteria can exhibit "cold shock", by being cooled rapidly. According to Adelberg's Medical Microbiology, rapid cooling from 37C to 5C will kill 90% of E.Coli bacteria in a sample.

[frogmasterg]

hey wanna know something how about you dont waste so much freakin money on LN and just take like 10 mins and go buy a freakin gallon of you choice and btw that wasnt 5 mins it was sped up ALOT

[SailorBarsoom]

Did you ever make a cake from scratch? Or grill a steak on the old Weber? Why not just go to Steak & Ale, and have somebody else do it for you?

Because sometimes, it's nice to do something yourself. To be a little creative. To bake your own bread, or make your own ice cream.

[Propagandhi900]

Not supposed to wear glvoes when handelling LN.

[agentcox]

That's true - the reason why is because the liquid nitrogen can run down your hand and the folds of the glove can keep it close to your skin, causing damage.

I did it anyway.

[windheavenX]

what douche said time stops at zero...FAILED..CLASS

[attack12332]

yea thats reeeeeaaaaaalllll smart

[Patrickwong007]

i wish i could do that stuff

[Retard0800]

wtf its not -400 its -196

[agentcox]

Yep. You're right.

[kaaiin60]

umm...........C and F man

[Retard0800]

its -196C And -321F Ok

[youebutr1]

hey retardo, liquid nitrogen is in liquid form at about -380 degrees

[Retard0800]

wth its LIQUID Nitrogen, Which Means The Gas Nitrogen Is Turned Into Liquid, And Its Temperature Is -196. How can liquid turn into liquid if its already a liquid.

[keyblade09]

actualy its only a -196 degrees

[Neumus]

is it really necessary the egg yolk?

[agentcox]

It makes for a creamier ice cream. It can be a health risk, so best go with pasteurized eggs if you can.

[Magnetohydrodynamics]

the health risk is very minimal at sub zero temperatures.

[DirtyWhiteBoy14]

frozen=]

no! germs=]

[SmallGrayBox]

Yep that cool video about −210°C cool lmao

[tytcka]

ice cream that we buy is also frozen with liquid nitrogen

[xxcutebootyxx]

Does it taste any different then usual ice cream???

[agentcox]

It's very creamy, with no little ice flecks in it like you'll get in the freezer. It's good!

[0nesian]

where can u buy liquid nitrogen

[thewii111]

watch the video again and he said where he bought it

[0nesian]

or you could just tell me now.

[agentcox]

A company called Airgas supplies it where I live. Whereever you are, you can look up "industrial gases".

[UZRA098]

wow very goood! liked it ama try that!!!!!!!!

[sk8girlflip1220]

if you want to make a milkshake use 1 cup of milk 1 tablespoon of sugar and a few drops of vanilla put it in a ziploc close then get a bigger ziploc with ice and a little bit of salt then put the bag with the mixture in side of thebig bag and shake for 5 minutes.

[Brassmonkay3]

I want to try that.

Liquid nitrogen = 75 kelvin

Liquid Helium = 4 kelvin

Im going to try it with helium

[agentcox]

Liquid helium will cost you about 12x the cost of liquid nitrogen - depending on your location, maybe $600 or so for 5 liters. For those prices, you better get it on film :)

[candylala]

is it edibleee????

[albertandfriends]

of course it is!!

[candylala]

ohh. the gear he was wearing just looked so like dangerous so i thought it would be like poisonous. haha im only like 13 so i never learnede about this stuff... or did i?

[MisterSynyster]

No just cold enough to burn the skin or eyes. That's right. Cold burns!

[candylala]

oh. ok. thank you

[Neur0ticism]

ProfWeaselBrains, is that dangerous as hell?

[Hellbenderlock]

The absolute zero is -273.15 C

and in Kelvins that's 0..

[Magnetohydrodynamics]

correct. at that point theres no vibration in the atoms, and therefore everything stands still (even time)

[TheUnnamedGent]

Is that true? That really makes you think about relativistic frames of reference.

[tjbrownj]

Time doesn't stop at absolute zero, dumbass (stop spreading bullshit). Ever heard of zero-point energy?

[Magnetohydrodynamics]

At 0K there is no movement (vibration on atom level, and because any movement is just directional vibration of atoms) to stand as a basis of observation of time (increasing chaos as in the laws of thermodynamics)

Therefore: you cannot observe time passing QED: time stands still.

[ikkyblob]

were can you buy it

[5ilverstein]

first off, absolute zero is not in -489..its -456.67 ...plus nothing is close absolute zero.. the record low is like.. -450 and yeah you can DEFF make ice cream with Liquid Nitrogen, and yeah its safe.. but im a chem major..so I probly dont kno shit.

[wookidoo]

To all people who say you can't eat this: You can because 78% of our atmosphere (the air you're breathing at this very moment) is N2 (nitrogen).

[Wardy125]

yeah but isnt eating and breathing two different things? i dont know im just saying... ive never really eaten nitrogen before :P... i dont think anyway. :D

[meinsla]

Yeah you have. air gets into your food all the time.

[omghowrandom]

when we breathe in nitrogen doesnt it not get absorbed into our bloodstream and is jus breathed back out along with the waste CO2 but when it goes down into your stomach and maybe beyond that, i really think it may harm your organs. this was just my opinion, i may gbe completely wrong... i may be partly right... you may be partly right and u also cud be completely wrong but i dont what the truth is.

[chuysal]

i already did it but some people say it is harmful to use liquid nitrogen....it is true??

[dakotah56671]

-400 degrees bullSH*t its only -180 - 400 you oaf thats almost absolute zero which is -489...

[tokinoyushi]

OK, for starters, it,s ok to eat the icecream because most of the liquid nirogen evaporated when he stirred it. And the reason why it is flamable is that liquid oxygen forms on the outside of the bowl. LIQUID OXYGEN IS HIGHLY FLAMMABLE DUE TO THE FACT THAT FLAMES NEED OXYGEN TO BURN, AND WHEN IT'S LIQUID FORM, IT TENDS TO BURN FASTER! (this is why they use it for rocket fuel)

[wwdONELOVEallday2]

you guys are fucking idiots

[VexMutz]

This kid inhaled liquid nitrogen and died because it froze his lungs...

[xxBlackpspxx]

it cant freeze your mouth and tangue, but it will hurt VERY much when its too cold.

[LizzyAston]

FLAMMABLE??? y????

[rob4500]

thats my table!!!!!!!!!!!!!!!!!!!!!!!!!­!!!!!!

[TheSolider]

Your better off not using gloves when handling Liquid Nitrogen.. >.>;;

[Yerza1001]

U can eat it but if u put too much LN2 but if its too cold it can freeze ur throat

[GotaMac]

If u put 2 much LN2 It would freeze into a solid block, so you couldnt even serve it.

[ArielCaboob]

LN doesnt exist, and how can u freeze your throat without freezing your toung and lips? or your fingers for that matter.

[meinsla]

Of course LN exists. You can get some at most universities. And did you even watch the video?

[ArielCaboob]

LN2 is the abbreviation. When your about to eat hot soup will you burn your lips / toung while tasting or swallow it like a fucking moron and burn your throat? yeah.. get a clue bro.

[iamabigfatbutt]

.....are you retared?

[ArielCaboob]

how so?

[Halosniper128]

So would you be able to blow this into a bubble and watch the bubble turn into a smoke bubble?

[boyboy53]

Why not just buy some? Cool video

[JcDizon]

Is the ice cream colder than normal?

[agentcox]

Nope, it's about what you'd get from regular ice cream, provided you don't put too much N2 in!

[imnoteamplayer]

Spin and I both really enjoyed this. Too cool... literally.

So yeah, Spin (and I) wanna know the same thing as jem up there... is the ice cream safe to eat? (I'd imagine so; Spin seemed skeptical.)

Maybe we'll just have to try it sometime... we got a kick out of the homeland security bit.

And Tyler should so beat you for that comment about his table... even though I know it's very true.

"I know this because Tyler knows this."

Man,you're ice cold... colder than that. ;)

[agentcox]

Well, hate to disappoint Spin, but it's safe. We all ate some, and I'd do it again anytime to prove it.

The reason it's safe is that the liquid N2 boils off very quickly and turns into harmless gas.

And even if it stayed trapped in the ice cream as a gas, nitrogen is over 70% of our atmosphere; it's not poisonous to us.

Glad you enjoyed the video!

[HigherTruth]

smart man.. i was thinking the same thing haha

[xvxjemxvx]

omg can you actually eat that or would it harm you ??

[chishilaoG]

yes you can eat it. Just don't put any alchohal in it.
