Was silly putty made by mistake?

Answer:
Yes. General Electric engineer James Wright made the 'bouncing putty' by mistake in 1943 - he had been working on various compounds for use as synthetic rubber for military supplies (boots and tires, especially). Seven years later, a toy store owner thought the serendipitous discovery would make a great children's toy.
