An Airancer (sometimes called a "skydancer", "windyman" or "flyguy") is a large inflatable device consisting of a long tubelike sleeve attached to a powered fan blower, which causes the sleeve to move in a dancing or flailing motion. Simple Airdancers resemble a vertical tube, but variants resembling humans with tube "arms" are also common. Airdancers are generally about 20 feet in total height and are often used as attention-getters for businesses such as car dealerships.
