Silly Putty® was discovered in 1943 by James Wright who mixed boric acid and silicone oil together. It was introduced to the public in 1950 by Peter Hodgson.

Although the exact formulas Crayola uses to make Silly Putty are proprietary, we can share it is made primarily from silicone and color pigments.
