For our afterschool program on Friday Melissa decided to teach the kids how to make ice cream in a bag. Before we had all the kids try it, we tested the process at home. Callan, Dad, and Mom passed around this batch of strawberry milk turned Ice cream for about ten minutes. What did we learn. First of all, the bags will definitely spring a leak if you throw them too hard. And second, if you don't rinse off the inner bag before you serve the ice cream, you end up with salty ice cream.
