ABSTRACT:
A magnetically actuated amusement device comprising a flat magnet of vertically oriented polarity and a bar magnet of longitudinally oriented polarity; the flat magnet is contained in a base and the bar magnet is suspended above the center of the base by a flexible tether. The tether is attached to the end of the bar magnet having a pole of unlike polarity to the upper most pole of the flat magnet within the base. The other end of the bar magnet is left free to be cantilevered up to a position where it is approximately as high as the tethered end by the strengths of the repulsive forces between the magnets.
