Krypton

Krypton is a noble gas that prefers to stand on its own and rarely plays with others. When stimulated with electricity, this natural element glows brightly and reliably.

From light sabers to kryptonite, Krypton’s unique green spectra have inspired many pop culture and sci-fi favorites, including our own Krypton Thinking Putty®! White by day, this putty glows the signature green in the dark. 

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.

Crazy Aaron's 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.
