Make a rainbow

Rainbows make everything better! Certain transparent materials will bend various colors of light differently. White light is then broken up into a dazzling rainbow. With every twist, pull and stretch, uncover a sparkling band of colors in your very hands with this Rainbow Thinking Putty from Crazy Aaron's.

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.
