Just like its name implies, Liquid Glass Thinking Putty® is unlike anything you’ve ever seen. This crystal-clear creation is so transparent that the tin often appears empty to the naked eye. 

Liquid Glass® putty becomes cloudy with use and changes back to crystal clear.

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.

Crazy Aaron's putty is non-toxic, won't dry out, and won't leave a sticky or slippery residue on your fingers.
