Did You Know...
...that in the early 1940s GE engineer James Wright was charged with a task of utmost importance to the war effort: develop a cheap substitute for rubber that could be used to produce tires, gas masks and a whole host of military gear. Wright tackled the task diligently -- and wound up inventing Silly Putty.
