Hidden deep in the heart of geodes, amethyst is one of nature’s best-kept secrets. When an exterior of dull, grey rock breaks open to reveal a pink and purple crystal masterpiece, it’s nothing short of epic. Make your own discovery with Epic Amethyst, a deep purple putty that gradually warms to bright pink before your eyes.

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.
