Abstract: Provided is a three-dimensional amusement device comprising a hollow transparent container. Within the container is wrapped, in a multitude of bends and directions, a hollow, transparent tube joined at its ends by a joining plug, thereby forming a continuous, multi-planar three-dimensional passageway network located entirely within the container. The joining plug is marked to indicate start and finish, and forms a carrier in the passageway. Within the passageway is located a small bead of mercury capable of moving as a bead through the continuous passageway from one end of the plug to the other. The object of the amusement is to tilt the container in such a fashion as to work the mercury bead from one end of the plug to the other via the continuous passageway.
