ABSTRACT:
An amusement device comprising first and second magnetic members; the first magnetic member being freelymovable in a base and the second magnetic member suspended from a tether and support arm attached to the base to a position within the influence of the first magnetic member. The second magnetic member is secured at one end to the tether in a manner by which the repulsive interaction between the two magnets maintains the second magnetic member essentially parallel to the base and perpendicular to the tether. The second magnetic member is freely rotatable around the point of tether attachment such that movements of the first magnetic member cause corresponding changes in the rotational orientation of the second magnetic member.
