ABSTRACT:
A decorative kinetic device which includes a transparent hollow dome containing a fluid and a plurality of small particles. The dome is open on its bottom and is mounted on a base having a pumping chamber formed therein. The top of the pumping chamber, which serves as the bottom of the dome, includes an intake hole and an outlet hole to provide flow paths between the dome and the pumping chamber. A pump impeller is positioned within the pumping chamber to circulate the fluid and the particles, the impeller being rotated by a motor positioned in the base below the pumping chamber. An extension member is attached to and extends vertically upward from the pump impeller into the dome and is adapted to receive a decorative object. A transport tube having an intake port and an outlet port is positioned in the dome such that the intake port is connected to the outlet hole of the pumping chamber and the outlet port of the transporting tube is positioned near the top of the dome. Rotation of the impeller causes the fluid and the particles to be drawn through and out of the pumping chamber into and through the transport tube, out of the transport tube near the top of the dome and down through the dome to the pumping chamber again. Simultaneously, the rotating extension member is caused to rotate.
