Good idea about the ice cream, but, actually, someone had the same idea and there is a commercially available ice cream cooled used liquid nitrogen – It is called dippin dots – http://www.dippindots.com – Ooops.. looks like it is already posted.

But before you have your ice cream you need to post a tutorial on how to cook a turkey with molten steel! Anyone out there crazy enough to do this?

But risk is the spice of life! This reminds me about an old joke about explosives:
How do you show you’re good with explosives?
Hold out all 10 fingers.

I know we’re a bright bunch here, or are supposed to be…. but agitating such a dangerous substance as liquid nitrogen with power tools sounds unnessicarily risky to suggest.

Nice.
Too bad I cannot get some liquid nitrogen to try it with :)

This is quite fun to do, and it tastes pretty decent. Read something like this about a year ago. Apparently, though, the person making the ice cream wanted to make an alcoholic ice cream float. However, he decided to mix the alcohol with the ice cream/nitrogen. However, he did not heed his chemistry class: he forgot that alcohol has a much lower melting point, and therefore it could appear to be warm when it is actually very cold. The result: he died from freeze burns on his insides.

#25, that may be true for paintball, but in general 80%N/20%O is not the same as nitrogen. very very different in most applications. anyway, a pressurized gas cylinder isn’t going to be very useful for ice cream.

Last time I wanted LN2 I looked under “cryogenics” in the phone book and found a couple companies willing to sell me a little bit of LN2, no problems.

But as #22 says, if you know someone at a chemistry or physics (or nuclear medicine) lab, you can probably get some for free.

[8] hpa is high pressured air pulled directly from our atmosphere, which just so happens to be composed of 78.08% nitrogen [http://en.wikipedia.org/wiki/Nitrogen] this means hpa is almost 80% “nitro”. You cannot get 100% nitrogen fills. HPA == “NITRO”

Sounds fun, could be ahem, interisting to do with either LH2 or LO2, or even better both togehter…

[turns on drill to start mixing]

To obtain lN2 simply go to your local University with an NMR facility, find a chemistry grad student, and buy them a beer. NMR uses it in combination with liquid Helium to cool the magnets. Better yet get lHe(4 Kelvin, -452 F). Airgas sells it but I don’t know if just anyone can buy it from them.

man i’ve really been meaning to do this “recipie!” my only problem is that i don’t know where to get liquid nitrogen!

theres a huge tank of the stuff (at least 500 gallon) on campus.
muahahahaha

We do this at Science North.

The last time I had it the cream was all lumpy.
