So clear you'll think the can is empty! Really!!Liquid Glass Thinking Putty develops a cloudy appearance when played with that quickly fades back to crystal clarity once you put it down. Unlike our other Thinking Putties, it will flow completely into a puddle on its own. Very different, unique and fun! Great for embedding objects like coins, action figures, and more!Thinking putty is non-toxic, odorless, and doesn't dry out no matter how long it is left out of its container when not being used. It is bendable and stretchable and can bounce like a bouncy ball.Product Weight:3.2 ounces of thinking Putty are found inside each 4 in. tin.Warning:CHOKING HAZARD. Small parts. Not for children under 3 yrs.
