ABSTRACT:
An advertising display device characterized by a rotating cardboard cylinder in which rotation is propelled by air currents in the room impinging upon air vanes extending outwardly from the cylinder. The device includes a low-friction rotational supportive being created by opposing magnetic fields. The device consists of a segmented pole supported at a lower end thereof by a floor or other horizontal surface; disposed at the top of the upper section of the pole is a magnet with a protruding pin. In the center of the top wall of the cylinder is another magnet with a corresponding recess. The pin of the first magnet rests in the recess of the second, and the magnets face each other with like polarity, thus repelling each other. This creates a floating effect, allowing for low frictional rotation.
