Liquid Glass Thinking Putty
You've never played with silly putty quite as cool as Liquid Glass Thinking Putty. Unlike the old-school pink goo, this modern putty is made from silicone rubber and is completely transparent. Knead it, roll it, twist it, tear it, or even bounce it and when you return it to it's storage tin, it melts back down into a weird, crystal clear pool. It's not as intelligent as liquid metal, but you will be lost in thought as you waste some time at the office contemplating this strange substance.
