Equipment

1 small zip lock bag
1 large zip lock bag (or large container with a leak proof lid)

Ingredients

½ cup cream
1 Tablespoon icing sugar
½ teaspoon vanilla extract
3-4 cups ice cubes
¼ cup salt

Optional flavorings

1 Tablespoon Strawberry puree
1 Tablespoon Blueberry puree
2 teaspoons cooca powder

Instructions

In the small zip lock bag (sandwich size) place the cream, icing sugar, vanilla and optional flavorings if using).
Remove excess air from the bag and seal closed.
In the large plastic bag or container add the ice and salt., plus the sealed bag of ice cream ingredients. Seal the large bag keeping air in it so that you can shake the ice around easily
Shake vigorusly until the ice cream freezes and gains a consistency similar to soft-serve ice cream.
Enjoy!

Notes

Always remember the salt, the experiment will not work without it
When you open the bag of ice cream be careful that none of the very salty water drips in!
Sprinkles: Add a few sprinkles or chocolate chips to the vanilla ice cream for even more fun
Cream: The ice cream will work with full-cream milk as well
Icing sugar: Honey or maple syrup will work too.
Salt: Any salt is fine to use but it is essential for this recipe to work. The salt reduces the melting point of ice allowing the temperature of the ice water in the outer bag to fall a few degrees below freezing meaning it is cold enough to freeze the cream or milk into ice cream. If you try this experiment without ice you will find it won't work.
