12. Super Glue
Another accidental invention that we can’t live without is super glue. Harry Coover, a researcher at Kodak Laboratories, was developing plastic lenses for gun sights. During the process he stumbled across a product that was sticky and made for a strong adhesive, which was made from cyanoacrylate. What’s interesting about the origin of super glue is that it was originally thought to be too sticky for actual use. It turns out that it works almost like magic, gluing almost anything permanently; just be careful not to glue your fingers or eyelids together—common childhood accidents.
