Abstract
A swinging bob toy having three bobs constrained on a string, the middle bob being slideably constrained between the two end bobs, and at least one of the bobs being reversibly separable into two partial bobs. A wide variety of new tricks and maneuvers are made possible by the separability of the bobs. The two partial bobs have roughly the same weight thereby providing balanced orbits. Each of the two partial bobs slides less easily along the string than a non-separated bob. The two partial bobs have roughly the same diameter along at least one axis thereby allowing visual illusions to be performed.
