Krazy Glue is a very strong adhesive that bonds instantly through reaction to minute amounts of moisture on the bonding surfaces. It works best on smooth surfaces such as plastic, glass, and even metal. It also works very well on human skin; it is said that if Krazy Glue glued everything as well as it does skin, you would never need any other glue.

Krazy Glue is one of the many cyanoacrylate based instant glues.
