Silly Putty® Running

Silly Putty® has often been billed as "The Real Solid Liquid®." That's because in its normal state, Silly Putty seems solid, but in fact is the liquid form of the substance. You can shape Silly Putty into just about anything, but it will slowly flatten with gravity.

If you roll Silly Putty into a ball and place it on a counter top, it will stay a ball for a while. Come back the next day, however, and you will notice your Silly Putty ball will have become more egg shaped. If you place the Silly Putty in the sun or another warm place, it will flatten more quickly. Put it someplace cold (like the refrigerator) and it holds its shape. That's because the temperature affects how quickly it "flows" -- the warmer the temperature, the faster the flow.

Another neat thing to try: Take a large blob of Silly Putty -- about three eggs worth -- and roll it into a ball. Flatten the ball slightly, then stick to the side of your refrigerator, a metal file cabinet or other non-porous vertical surface. During the next few days, the Silly Putty will begin "flowing" down the surface. It won't run all the way off -- it eventually slows to where it seems like it's not moving at all. At Silly Putty headquarters, we've had a piece of Silly Putty running down the side of a filing cabinet for about six months, and it's still going!
