ABSTRACT:
A battery powered motor drives a fan blade to emit an air stream along a predetermined path and, through suitable speed reducing and motion transmission means, one or more members each carrying a dip ring at one end which is reciprocally moved between a first position wherein the ring is immersed in a liquid bubble forming material and a second position wherein the ring is in the path of the air stream, thus emitting a stream of bubbles. By providing two movable members the dip rings carried thereby may be of different sizes and arranged oppositely in their first and second positions to emit an essentially continuous stream of alternately large and small bubbles. The rings are preferably formed as open cylinders having a series of axially extending slits through the wall thereof. The fan blade is preferably of flexible material, bent to the proper pitch and reinforced with a string or thread stretched across the blade axis and secured to its ends.
