Kid Science: 5-Minute Ice Cream
Making ice cream is a delicious way to learn about science and the changing states of matter and chemical reactions. When salt is added to ice it causes it to melt, but also lowers the freezing temperature. This chemical reaction between salt and ice creates a very cold environment for the cream to start to change from a liquid to a solid!
1. Pour 2 Tbsp sugar, 1 cup half & half and 1/2 tsp vanilla into a plastic freezer bag.
2. Fill another plastic freezer bag 1/2 full with ice. Add 1/2 cup rock salt.
3. Place the bag with the cream mixture into the bag of ice, making sure it is surrounded by the ice and salt. Using towels to protect your hands from the cold, shake the bag vigorously for about 5 minutes.
4. Take the bag with the cream out and wipe off the outside.
5. Scoop out some ice cream and enjoy!
6. Add additional toppings if desired.
