Duct tape, sometimes called duck tape, is a very strong adhesive tape with a cloth backing . Usually duct tape is grey or black, but it is made in other colors including transparent, red, orange, yellow, green, blue, purple, flames, zebra stripe, lepaord spot, tye dye, and others. People use duct tape to repair many things, for example a broken handbag or a broken chair.
Duct tape was designed during World War II. It was first used to keep water out of ammunition cases. It was found to work so well that people started using it to fix many other things. Duct tape was also called "100 mph tape" by the military because it is said the tape will still stick in winds at speeds of 100 miles per hour. Duct tape got its name from its use on heating and air conditioning ducts but oddly enough, that is the one use that the tape is not very good for. It is illegal in California to use duct tape on ducts and most professional builders in the United States are not allowed to use it either.
Duct tape is also great for making things like wallets, purses, clothes, and sometimes even sculptures. The use of it as an art medium is fairly new, though.
