Silly Putty is a toy based on silicone polymers which display unusual physical properties. It bounces, but breaks when given a sharp blow and can also flow like a liquid. It contains a viscoelastic liquid silicone, a type of Non-Newtonian fluid, which makes it act as a viscous liquid over a long time period but as an elastic solid over a short time period. It was originally created by accident during research into potential rubber substitutes for use by the United States in World War II.
The name Silly Putty is a trademark of Crayola LLC; the company's manufacturer is based in Easton, Pennsylvania. Other names are used to market similar substances from other manufacturers.
