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!
