An airdancer is a large inflatable device comprising a long tube attached to a fan which causes the tube to move in a dancing or flailing motion; some variants may resemble humans with tube arms. Airdancers are generally called an inflatable tube or a moving figure, such as "windyman", "skydancer", "tube man" and "flyguy"; the phrase "Wacky Waving Inflatable Arm Flailing Tube Man" has also become a popular name for the decorations after originating in an episode of Family Guy.
The product was invented by Peter Minshall, an artist from Trinidad and Tobago, along with his team, including Israeli artist Doron Gazit, for the 1996 Summer Olympics. Minshall originally called his invention the "tall boy". Gazit eventually patented the concept of an inflatable, dancing human-shaped balloon and licensed his patent to various companies which manufacture and sell vertical inflatables, including one which markets its product as the "Airdancer".
