Play and Freeze - Having Fun Making Ice Cream

Steve Spangler has created a toy that relies on science to make ice cream! He uses a ball with two cylinders inserted. One contains rock salt and water, while the other contains the ice cream ingredients. Once sealed, a family kicks the ball around for 20 minutes to mix and freeze the concoction. Voil! Exercise and dessert are rolled into one activity! You can purchase the ball or visit the Steve Spangler Science website to learn another method of making ice cream. This is a terrific way to introduce phase change or the states of matter to early elementary scientists!
