Super Glue was rejected because it stuck to everything
The strong and fast-acting adhesive used to make glues like Fevikwik was initially discovered by scientists in 1942. This discovery was rejected because it stuck to everything it came in contact with. In 1951, the 'Super Glue' was rediscovered by researchers Harry Coover and Fred Joyner, who sold it as a commercial product in 1958.
