Ice-Cream In A Bag

Last week we tried a science experiment in Andrei's homeschool pre-school class. It was really cool. We learned about chemical reactions and how to mix ingredients. It was also delicious and all the kids loved it. Here's the recipe:

What you'll need:

1 tablespoon sugar (Splenda granulated works too)

1/2 cup milk or half & half (we used Horizon whole organic)

1/4 teaspoon vanilla

6 tablespoons rock salt (or ice cream salt)

1 pint-size plastic food storage bag (e.g. Ziploc) 

1 gallon-size plastic food storage bag

Ice cubes

How to make it:

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

Put milk, vanilla, and sugar into the small bag, and seal it.

Place the small bag inside the large one, and seal it again carefully.

Shake until the mixture is ice cream, which takes about 5 minutes.

Wipe off the top of the small bag, then open it carefully. Enjoy!

Tips:

A 1/2 cup milk will make about 1 scoop of ice cream, so double the recipe if you want more. But don't increase the proportions more that that -- a large amount might be too big for kids to pick-up because the ice itself is heavy.
