It&#;s suitable for indoor and outdoor use thanks to its strength and water resistance. It&#;s available in various widths, lengths and colours &#; with the most common colours being black, silver and clear.
There&#;s even duct tape that glows in the dark, which is useful for crafts, Halloween decorations or locating items in dark settings. As well as this, there&#;s double-sided duct tape which is coated in adhesive on both sides. This is ideal for sticking two objects or surfaces together without making holes or the tape being visible.
Duct tape can have different grades, which help determine the applications it should be used for. The grade refers to how the tape is made &#; so the type of adhesive used and the strength of the cloth backing. The strength of the cloth backing depends on the number of threads it has, with more threads making it stronger and therefore more difficult to tear.
It was originally called duck tape because during World War II the US military needed a waterproof tape to keep moisture out of ammunition cases. Johnson & Johnson manufactured the tape and, because of its water resistance which emulates water off a duck&#;s back, it was referred to as &#;duck&#; tape.

People often joke that anything can be fixed with a little duct tape. While duct tape can't fix everything, it's definitely a versatile product that can be used in innumerable ways.
Duct tape was created during World War II, when factory worker Vesta Stoudt discovered soldiers had a hard time opening the ammunition boxes she and her colleagues were sealing with paper tape, then dipping in wax. Stout penned a letter to President Franklin D. Roosevelt, proposing the war effort employ a cloth-backed, waterproof tape instead. Roosevelt agreed, and soon a Johnson & Johnson operating company was manufacturing the durable, easy-to-remove tape, colored Army green.

The tape was crafted from a thin piece of duck fabric &#; a heavy, woven canvas &#; coupled with a plastic coating and rubber-based adhesive. Some say this new sealant had no name during the war, while others assert people began calling it "duck" tape after the duck fabric, or possibly because it resisted water, much like a duck's body.
When the war ended, the construction industry began using the tape to patch together ventilation ductwork, and it soon became known as "duct tape." Manufacturers quickly swapped out its original green color for silver tape that matched the ductwork.
By the s duct tape had gone mainstream and was found in many, if not most, U.S. households. Today, it's available in a wide assortment of materials and colors, and consumers have come up with all sorts of creative uses for it. Here are 10 of them.
Bonus use: Help out on a lunar mission: One of the more impressive uses of duct tape came in , during the famous Apollo 13 lunar mission that went awry. During the mission, two oxygen tanks exploded. The explosion forced the astronauts to move into the spacecraft's lunar module, where carbon dioxide levels rose precipitously. The crew used duct tape (among other items) to patch together a CO2 filtering system featuring an incompatible round hole and square filter.

Despite duct tape's versatility, there are some things it can't do. Duct tape doesn't work as painting tape, for example. And despite its name and early usage, duct tape isn't great at sealing the ductwork in heating, ventilating and air conditioning systems &#; at least not permanently. The U.S. Department of Energy's Lawrence Berkeley National Laboratory conducted a study of various duct sealants and only one failed: duct tape. The testers think the heat in HVAC systems degraded the tape glue.
