1. Get some ice, salt, 2% milk, vanilla, sugar, a gallon Ziploc bag, and a sandwich Ziploc bag.
2. Fill the gallon bag with ice and add 6 tablespoons of salt.
3. Put ½ cup of milk into the sandwich bag.
4. Add ¼ teaspoon of vanilla and 1 tablespoon of sugar to the sandwich bag.
5. Put the sandwich bag into the gallon bag. Make sure both bags are sealed tight.
6. Shake the bags. (This part is fun for kids!)
7. Take the sandwich bag out of the gallon bag. Lo and behold, it will contain ice cream. No joke. (I’d never joke about ice cream, people.)
8. Eat!
