Fred Joyner was working on that project and at one point used the rediscovered Super Glue and tested it by spreading ethyl cyanoacrylate between a pair of refractometer prisms. To his surprise, the prisms became stuck very solidly together. This time, Coover did not abandoned the cyanoacrylate (Super Glue), rather, he realized the great potential of a product that would quickly bond to a variety of materials and only needed a little water to activate, which generally is provided in the materials to be bonded themselves.
