Leave Earth's atmosphere and blast off to a new galaxy Use the heat of your hands to transform your Thinking Putty¨ from deep space blue, to ultraviolet purple and then to cosmic pink. Stretch and pull your way into Intergalatic space and create infinite galaxies. Vibrant colors change as you play-flecks shine and shimmer like the stars. 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.
