Deep dives

The Accidental Invention of Superglue

Superglue was invented by Dr. Harry Coover in 1951 while he was attempting to create a heat-resistant material for aircraft canopies. During his research, he discovered that cyanoacrylate, the chemical he was working with, had adhesive properties that stuck virtually everything together, leading him to theorize its potential as a glue. By 1958, this substance, initially known as Eastman 910, was commercialized and gained widespread popularity due to its rapid bonding capabilities, requiring just a single drop to join materials. The unexpected success of superglue was significantly bolstered when Coover demonstrated its power on a game show, lifting a man with only one drop, ultimately branding it as 'super glue' and prompting consumers to seek it for home use.
