Query: It's silly putty!

This has all the properties of silly putty: it bounces; it's smooth and shiny; it stretches almost infinitely; it picks up newspaper ink; you can work it to the thickness of saran wrap; you can capture air in it and pop the bubbles. Oh, and it's therapeutic.I got the yellow "soft" variety. I would definitely not call it soft. It's hard to believe there are four grades of this stuff that are more firm than the yellow.I have large hands, and 4 ounces of putty is a good handful. You'd have to buy eight plastic eggs of the original silly stuff to get 4 ounces.
