Crazy Aaron's Thinking Putty Freshly sprung flowers are nature’s way of celebrating the season. Join in on the fun with this putty that is a rich lilac purple when cool, it warms to a happy spring green. As part of the Hypercolor® Collection this color changing Thinking Putty® is heat sensitive, meaning it starts one color and changes to another through heat transfer. The more you play the more the color will change! Thinking Putty® helps build hand and finger strength through a fabulous tactile play experience with unique, unexpected properties and provides relaxing, yet stimulating interaction for anyone with sensory integration issues. Thinking Putty® is non-toxic, won't dry out, and won't leave a sticky or slippery residue on your fingers, so it's great for stretching, molding, bouncing, tearing, popping and playing by kids and adults alike.
