In the year 1943, Silly Putty was first invented by James Wright when he accidentally dropped boric acid into silicone oil. Since then, Silly Putty has remained a popular science toy! It made its big debut at the International Toy Fair in New York in 1950, packaged in plastic eggs to be sold as an Easter novelty item. Silly Putty was invented in 1943 when an engineer accidentally dropped boric acid into silicone oil. By accident they made an enduring toy, Silly Putty. It was originally created during WWII as scientists were searching for a substitute for rubber to use during war time. The ether solution of the silicone oil is washed with an aqueous sodium bicarbonate solution. One way to make the polymer is by reacting dimethyldichlorosilane in diethyl ether with water. Silly Putty is a patented invention, so specifics are a trade secret. Warm putty is extremely sticky, but when cooled, the putty returns to the same state before the microwaving. I microwaved the putty in a drinking glass for about 3 minutes. According to the official Silly Putty website, the combination of silicone oil and boric acid creates what is referred to as a solid liquid, which allows the product to bounce, stretch and be molded. Why does silly putty stick to silicone?īecause of the silicone compounds in the Silly Putty, the putty clings to rubber and plastics more than other products. If Silly Putty is left out of the container over a period of several years, it may harden due to other ingredients contained in the putty. Silicone is an oil-based product and by nature will not dry out. SILLY PUTTY is made primarily from silicone and color pigments. The invention of Nutty Putty, later renamed Silly Putty, happened accidentally. Wright (Ma– August 20, 1961) was a Scottish-born inventor, researcher and chemical engineer at General Electric who invented Silly Putty in 1943 while looking for a replacement for rubber. Crayola acquired the exclusive manufacturing rights to Silly Putty in 1977. It was introduced to the public in 1950 by Peter Hodgson. Silly Putty was discovered in 1943 by James Wright who mixed boric acid and silicone oil together. Other names are used to market similar substances from other manufacturers. ![]() The name Silly Putty is a trademark of Crayola LLC. ![]() It was originally created during research into potential rubber substitutes for use by the United States in World War II.
