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. Made in the USA from nontoxic silicone and never dries out! Stretch it, bounce it, pop it, tear it, and sculpt it! Fun for ages 3+. Thinking Putty is manufactured with the help of exceptional individuals challenged with disabilities.
