Don’t stay up too late playing with your Witching Hour Thinking Putty®! Stretch and pull the putty to make the bats swoop through the three shades of purple glitter. Watch it light up white in the dark with the radiance of Glowbrights®. 

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.
