Silly Putty Original

Looking for a solution for fidgety hands?  Why not go with the original kid-safe putty?  A less messy alternative to slime, with lots of fun activities to look up! Silly Putty is a toy based on silicone polymers that have unusual physical properties. It bounces, but it breaks when given a sharp blow, and it 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 during research into potential rubber substitutes for use by the United States in World War II!   Recommended ages 3 and up.
