Eraser putty, also known as silly putty, is a silicone-based putty that can be used to erase pencil marks. It is soft and pliable, and it can be molded into any shape. Eraser putty is non-toxic and safe for children to use.
Eraser putty was invented in 1943 by James Wright, a General Electric engineer. He was working on a synthetic rubber project when he accidentally created a batch of putty that was too soft and sticky to be used for tires. Wright realized that the putty could be used to erase pencil marks, and he began to market it as a toy. Eraser putty quickly became a popular toy, and it is still sold today.
