"One of the best-selling holiday items, the Melting Snowman, comes in a reusable plastic container, so kids can build their own snowman, decorate him, watch him melt, then start the fun all over again. Each snowman putty slime kit includes everything kids need: a hat, googly eyes, nose, pipe, buttons, and stick arms. Putty can be formed like real clay, and then it slowly melts into a goopy blob when exposed to room temperature.
