Today Analise and I made Chocolate, Chocolate Chip ice cream in the play and freeze ball. The ball has two openings one on the top and the other on the bottom. On one side, we filled the ball with ice all the way to the top and added ½ cup of rock salt and closed the lid tightly. Then on the other side, we filled the ball with 2 cups of cream, 1 & ½ teaspoons of vanilla, 1/3 cup plus 2 tablespoons of sugar and ½ cup of chocolate chips. We then started playing with the ball. We talked about why we added salt to the ice. We learned that it causes a temperature drop that slows the melting rate and increases the freezing rate. After 15 minutes of playing with the ball we got to try Analise's delicious ice cream.
