Glue

Glue dates back to prehistoric times. Artists once mixed colorings with raw eggs, dried blood, and plant juices to make sticky paints for cave murals.

Ancient Egyptians and other peoples learned to make stronger glues by boiling animal bones and hides.

Super Glue, also known as cyanoacrylate, was originally accidentally discovered in 1942 during a search for materials to make clear plastic gun sights during World War II. A team of scientists headed by Harry Coover Jr. stumbled upon a formulation that stuck to everything that it came in contact with: Coover abandoned that formulation at the time as it wasn't suitable for his current project, being too sticky.

In 1951, Dr. Coover was the supervisor of an Eastman Kodak project looking at developing a heat resistant acrylate polymer for jet canopies. Researcher Fred Joyner rediscovered Super Glue whilst working on the project and and this time Coover recognized its rue commercial potential.

"Eastman #910" (later "Eastman 910") was the first cyanoacrylate adhesive to be sold, in 1958.

A one square inch bonding of Super Glue can hold around one ton.

The glue on Israeli postage stamps is certified kosher.

If you put superglue on cotton it will catch fire.
