Abstract: The present invention provides a water tower generally having a base portion, a tower support attached to the base portion, and a fluid vessel attached to the tower support and containing a fluid. A buoyant vessel having a first magnet attached is contained within the fluid vessel. A first arm defining a cam slot and rotatably attached to the tower support by a first pivot pin guides a second arm, an end of which is disposed within the cam slot. The second arm is rotatably attached to the tower support by a second pivot pin. A second magnet is attached to a second end of the movable arm. In operation, the first arm is rotated to move a second arm, bringing the first and second magnets into alignment. The magnets create an attraction force which sinks the buoyant vessel within the fluid, giving the water tower the appearance of being full. When the first arm is rotated so magnets are taken out of axial alignment, the attraction force of the magnets is diminished, and the buoyant vessel floats.
