8. Super Glue
Super Glue is one of the interesting accidental scientific discoveries and inventions made by mistake – twice. The first time was during the WW2 when Dr. Harry Coover was experimenting to make plastic hoovers for gun sights, but at that time the potential of Sper Glue was not recognized. The other (re)discovery was some ten years later when Fred Joyner accidentally spilled some ethyl cyanoacrylate on prisms that stuck very hard together. Now this time Dr. Coover recognized the importance of this substance and Super Glue was patented.
