Moomin and Rook made Howtoons Ice Cream tonight in a couple of heavy-duty ziplock bags. The cream and eggs and sugar were in a small bag locked inside a larger bag of ice and salt. So, they wore welding and gardening gloves and threw the bag of ice back and forth for a while!
I had the idea to put the bag onto the bouncy horse (the kind on springs that little kids ride), which worked for a while. Standing next to it and bouncing the horse worked better than actually riding hte horse while holding a big wet freezing bag.
20 minutes later they put chocolate chips in it and voila, ice cream!
