I usually made Jell-O Jigglers, if you don't have molds follow the directions on the box and pour it into a pan and use cookie cutters to cut out the shapes. Even the kids who don't like Jell-O like to "play" with them, but I did find that most kids ate them. Popcorn was another thing that they all liked, although it can be messy and thrown around easily, I found this didn't happen too often and it does sweep up easily.
