Cool and calm, Falling Water flows like a cascading waterfall. This blue Liquid Glass® Thinking Putty® shimmers with clarity and motion, just like the dolphin who dives in its depths. A refreshingly unique way to play. The Liquid Glass® collection includes Falling Water, Rose Lagoon, Lily Pond and Morning Dew. Liquid Glass® is the only Thinking Putty® collection that stands alone in putty properties. Liquid Glass® will never have the elasticity that the other putties do; they simply don't have the composition. Liquid Glass® stretches a bit before breaking and does not bounce. This Thinking Putty® is meant to be enjoyed for its transparency. 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.
