Silly Putty

Silly Putty is a toy containing silicone polymers that have unusual physical properties. It can flow like a liquid, bounce, stretch, or break depending on the amount of physical stress to which it is subjected. It contains viscoelastic liquid silicones, 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 during research into potential rubber substitutes for use by the United States in World War II.^[1]^[2]^[3]
