Liquid Glass - Crazy Aaron's Thinking Putty.

So clear you'll think the can is empty.  Really   Crystal clear Liquid Glass Thinking Putty develops a cloudy appearance that quickly fades back to crystal clarity once you put it down.  Unlike our other Thinking Putties, it will flow completely into puddle on its own. It'll Be Like Putty In Your Hands It's called Thinking Putty because while you do whatever you want with it, your brain relaxes and opens up to all kinds of creative thinking. Need it? Yes. And you can also knead it. Or bounce it, bend it, tear it, stretch it, snap it, pop it. Comes in a 4" dia x 1-3/8" tin.
