Is It "Duct" Tape Or "Duck" Tape?

Is It "Duct" Tape Or "Duck" Tape?

A common mispronunciation of duct tape is "duck" tape, but it may not be much of a mistake at all. The tape was invented during World War II because the soldiers needed a waterproof tape that would keep moisture out of ammunition cases. The soldiers later used it for repair purposes, after seeing how well it holds up. Because it was developed for the military, the tape was initially army green before it became available in the metallic silver common today. Later, it began being used to seal ducts, which is how it became known as "duct" tape. The color was changed to silver to match the ducts. Ironically, research discourages its use on ducts, as the tape becomes brittle under typical duct conditions.
