Duct tape was originally called Duck tape. It was green in color and used in the Military first. Generally used to tape Ammo cans shut. After WWII the tape was colored silver and used on Air Ducts during the housing boom when the troops came home. Duct tape can be used in emergency situations to repair almost anything, it can help house windows withstand hurricane winds, hold car bumper covers on and restrain prisoner's hands and feet in the event hand cuffs are unavailable.
