This special putty features three incredible color-shifting effects that reveal a rainbow of hues. Watch it transform with the warmth of your hands and them morph again in the sunlight. But that's not all - turn off the lights and see it glow! 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.
