ICE cream

You've never had ice cream until you've had it made from liquid Nitrogen. Yesterday at the end of our review session for my Chem final, my prof made the class ice cream using milk, half and half, sugar, vanilla, and liquid Nitrogen. It takes all of 5 minutes--its great! For those of you who care, liquid Nitrogen comes in at about 70 Kelvin, which is really cold (~ -203 degrees Celcius, you can figure out Farenheight (sp?)). If any one wants to have some fun, get yourself some liquid Nitrogen. Its fun stuff, and not too dangerous. That's it. I just wanted to share my ice cream experience w/ ya'll.
