Professor Marty's Clever Putty Heat Sensitive can stretch like rubber and bounce like a ball, and because it's silicone-based, it won't dry out or crumble over time. It's part toy, part stress reliever, part physical therapy and entirely addictive. Once you start playing, it's hard to stop! Clever Putty is fun and irresistible.
