Abstract
An apparatus for generating bubbles from a stationary loop inside a housing is described. The device includes a housing, a reservoir of bubble-making solution, a fan that generates an air stream, and a pump that supplies said bubble-making solution to a stationary film-producing mechanism. The stationary film-producing mechanism comprises a loop with an opening through which air travels, a film-forming edge, a bubble-releasing edge, a first orifice on an exterior surface of the loop, and a second orifice on an interior surface of the loop. Solution supplied to the film-producing mechanism enters the loop through the first orifice, exits the loop through the second orifice, and forms a film of solution along the film-forming edge of the loop, wherein at least one bubble of solution is released from the bubble-releasing edge.
