Duct tape is a strong, wide adhesive tape with a fabric backing that can stick to almost anything and hold tight even in tough conditions. The shiny, waterproof surface (usually silver-gray, though it comes in many colors now) peels off a roll and tears by hand, making it quick to use for repairs, building projects, or temporarily holding things together.

Originally developed during World War II to seal ammunition boxes and keep moisture out, duct tape became famous for fixing almost everything: broken toys, ripped backpacks, cracked hoses, loose car parts, and even spacecraft repairs. Astronauts on Apollo 13 used duct tape to help build an emergency air filter that helped save their lives. Around the house, people use it to patch torn screens, bundle cables together, or reinforce a cardboard box.

What makes duct tape special is its versatility. It's strong enough to hold weight, flexible enough to wrap around corners, and sticky enough to work on wood, metal, plastic, and fabric. When something breaks and you need a quick fix, duct tape is often the first tool people reach for.
