A bellow is a device that produces a controlled stream of air when operated. Bellows consist of a flexible chamber with handles or a foot pedal that, when compressed and released, forces air through a nozzle or tube. Historically used for stoking fires and forges, bellows are employed in metalworking, glassblowing, organ music and various crafts. Modern versions include electric air pumps and hand-operated designs.
