Silly Putty is a stretchy, bouncy substance that was invented in 1943. It is made from silicone polymers, which give it its unique properties. When you pull it apart, it stretches, but when you hit it, it bounces. It can also pick up ink from newspapers and other printed materials, making it a fun toy for kids and adults alike. Originally created as a potential rubber substitute during World War II, Silly Putty became popular as a toy in the 1950s. It is often sold in small, egg-shaped containers and comes in various colors. Its versatility and playful nature have made it a classic item for generations.
