"God made the world, duct tape holds it together"
(unknown author)

Duct tape was invented for the U.S. Military during World War II. The original use was to keep the moisture out of the ammunition cases. Because it was waterproof, people referred to the tape as “Duck Tape.” Also, the tape was made using cotton duck - similar to what was used in their cloth medical tapes. Military personnel quickly discovered that the tape was very versatile and used it to fix their guns, jeeps, aircraft, etc. After the war, the tape was used in the booming housing industry to connect heating and air conditioning duct work together. Soon, the color was changed from Army green to silver to match the ductwork and people started to refer to duck tape as “Duct Tape.” (By the way, "Duck Tape" is now a registered trademark of Duck® brand (a division of Henkel Consumer Adhesives) in Avon, Ohio.
