I have made this very successfully at an outdoor camp (a visitor brought in the ice) and with my Pippin aged 5+6

Ingredients:

1/2 cup milk (it doesn't matter what kind, whole, 2%, chocolate, etc.
1 Tablespoon sugar
1/4 teaspoon vanilla (you might try other flavourings)

Method:
1.Add these to a medium size zip lock freezer bag and zip shut.
2.Place that bag in a larger zip lock bag
3.Add ice to fill bag 1/2 way, 6 Tablespoons salt (rock or regular)
4.Zip that one shut and shake, turn, toss, and mix the bag. In about 5-10 minutes you will have cold hands and yummy ice cream.

Warnings:
Don't double this it doesn't seem to work.
Be sure you get all the salt off the small bag before you open it.
