Super glue, Krazy glue, Eastman 910 and similar glues are all a special type of glue called cyanoacrylates. Cyanoacrylates were invented in 1942 by Dr. Harry Coover of Kodak Laboratories during experiments to make a special extra-clear plastic suitable for gun sights. He found they weren’t suitable for that purpose, so he set the formula aside. Six years later he pulled it out of the drawer thinking it might be useful as a new plastic for airplane canopies. Wrong again–but he did find that cyanoacrylates would glue together many materials with incredible strength and quick action, including two very expensive prisms when he tried to test the ocular qualities of the substance. Seeing possibilities for a new adhesive, Kodak developed “Eastman #910” (later “Eastman 910”) a few years later as the first true “super glue.” In a now-famous demonstration conducted in 1959, Dr. Coover displayed the strength of this new product on the early television show “I’ve Got a Secret,” where he used a single drop placed between two steel cylinders to lift the host of the show, Garry Moore, completely off of the ground.
So it was tested for scopes, but not actually USED. It’s first pratical application was as a glue.
Still – it is a fact I shall store away for later use 🙂
