James Wright, a GE engineer, came upon the material by mixing silicone oil with boric acid. The compound, acted very much like rubber in its ability to rebound almost 25 percent higher than a normal rubber ball. This “Nutty Putty” as it was first called, was impervious to rot, soft and maleable, and able to stretch many times its length without tearing. One other unusual quality was that Silly Putty ® could copy the image of any printed material that it was pressed upon. In 1949, the material was sold under the trade name of Silly Putty ®, selling faster than any other toy in history with over $6 million in sales for the year. Silly Putty is now the registered trademark of Binney & Smith Inc.
