how to make ice cream, without them fancy blenders and all... Options

[Note]

kay. we did this in science lab, so don't blame me if it blows up.

what you need
Milk
Heavy Cream (Half and Half will do nicely)
Real Vanilla (not that fake junk that's sold!)
Sugar
Liquid Nitrogen
a person over 18 (to buy Liquid Nitrogen)

Stainless Steel mixing bowl
Wooden mixing spoon
Gloves
A big sink or a level place out side


IMPORTANT! Simple rules for handling Liquid Nitrogen

I could say DO NOT LET IT TOUCH SKIN but someone will be a stupid and do it anyway. The truth of the matter is that the human body is so hot to the Liquid Nitrogen that it will boil in your hand with out any harm to you. However, the instant you contain the liquid Nitrogen, like in a fist, you increase the pressure of the gas trying to escape. The pressure builds up enough to give you a very bad freezer burn. Enough to need medical attention, so take my word for it and don't. i'm a geek i know.

kay, how to make

1.
First figure out how much you want to make. Multiply the total amount of ice cream by five to get the amount of Liquid Nitrogen needed to freeze the ice cream. A gallon of ice cream will thus need five gallons of Liquid Nitrogen.

2.
Mix the Milk, Cream, Vanilla and sugar in the mixing bowl. The ratios should be twice as much cream as milk and about 8 tbsp of vanilla for every gallon of liquid. Sugar should be about 1 cup dry measure per gallon. If that's too sweet then half it. I do not know how artificial sweeteners react to the cold, so I don't recommend the usage of them.

3.
Mix the ingredients until the sugar has dissolved into the milk and cream. Add in any fixings (candy, coffee, other flavors). Move to the sink if you haven't already.

4.
Pour in the Liquid Nitrogen slowly and mix with the wooden spoon until completely frozen, which should be about 10 minutes. Wear the gloves, because it's going to be cold.

5.
For a better freeze, prepare the icecream in a pressure cooker, and after adding the Liquid Nitrogen, clamp shut for 5 minutes.

again. don't blame me if something blows up. you see, my science teacher is very crazy. he threw some dry ice in a water bottle today and closed the cap. KaBOOM! all the fishes died. [shakes head]
