Strange Attractor Thinking Putty® has a mind of its own as well. A deep, mysterious black with subtle green sparkles, it comes alive when charged with the included magnet.

"Strange attractor" is the name of a mathematical equation that is commonly part of chaos theory. This equation creates a fractal—a never ending, non-repeating pattern within a dynamic system. Basically, a strange attractor has a mind of its own and creates beautiful patterns in design, art, and nature.

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.
