My kids received this at Christmas time. We used it once then and then just recently on a hot day. They did learn some science with the ice and salt method. For the quantity of liquid you get it doesn't seem worth the time it takes. It takes longer than the time on the instructions. It is hard to put this together and adult supervision MUST be taken seriously as the ice gets extremely cold. I thought it would be great to have in the summer, but I think we'll keep it in the closet.
