Tasty Science

Silly guy just finished up his unit in Science "Changes in Water and Matter."  We just had to do this tasty experiment:  making ice cream in a bag.  Here is the recipe if you want to give it a try.  As you  can see this experiment got three thumbs up.
What you'll need:

1 tablespoon sugar
1/2 cup milk or half & half
1/4 teaspoon vanilla
6 tablespoons rock salt
1 pint-size plastic food storage bag (e.g., Ziploc)
1 gallon-size plastic food storage bag
Ice cubes

How to make it:

1.  Fill the large bag half full of ice, and add the rock salt.
Seal the bag.

2.Put milk, vanilla, and sugar into the small bag, and seal it.
3. Place the small bag inside the large one, and seal it again carefully.

                           4.  Shake until the mixture is ice cream, which takes about 5 minutes.
5.  Wipe off the top of the small bag, then open it carefully. Enjoy!
