We made ice cream with rock salt in Mr. Olson's class!!!!!! YUMMM!


Ingredients:

• 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 (or Ziploc)
• 1 gallon-size plastic food storage bag
• Ice cubes

Directions:

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!

You can put chocolate, strawberry, or caramel syrup in the small bag along with the milk, vanilla, and sugar to add flavoring! You can also add marshmallows or bunney mallows :) or sprinkles, too! YUMMM

Science:

Salt water freezes at a much lower temperature than fresh water so adding salt to ice makes the ice to melt and the temperature to drop. This cooling effect is used to freeze the ice cream.

Here is a molecule of NaCl, or AKA rock salt!
