This activity is appropriate for: preschool - 3rd grade / 3 - 8 years Students of all ages love this cool activity—making their own ice cream! You will need the following ingredients: 1 tablespoon sugar ½ cup milk or half & half ¼ teaspoon vanilla extract 6 tablespoons rock salt (the bigger the granules, the better) Ice cubes Pint-size zip-close food storage bag Gallon-size zip-close bag Combine the sugar, milk and vanilla extract in the pint-size bag. Squeeze out as much air as possible, and then seal it tightly. Next, place the ice and rock salt in the gallon-size bag, and then place the smaller, sealed bag inside as well. Seal the larger bag, again squeezing out as much air as you can. Wrap the bags inside a towel to protect your hands from the cold. Shake the bags until the mixture hardens (about 5 minutes). Feel the small bag to check whether it’s done. When it’s done, remove the smaller bag, and then add in extra treats like crushed cookies, chopped fruit, etc. (Makes about 1 cup.)
