A decorative liquid globe is provided with an electric motor and pump unit for recirculating liquid within the globe. The unit can be located entirely below the liquid chamber and have only an inlet tube or passage and an outlet tube or passage interconnecting the unit with the liquid chamber. Alternatively, providing that the unit can be properly housed in a self-contained combination motor and pump unit, it may be completely immersed in liquid and the pump inlet and outlet effect the recirculation. In this latter construction, electrical wires can pass through and be effectively permanently sealed with a wall of the chamber in a manner that avoids the potential of electrical shorting. In neither instance is there any requirement of moving parts such as shafts passing through a wall of the chamber, and the leakage potential of the prior art globes is eliminated. A movable decorative device within the globe may be made to respond to liquid recirculation without any mechanical interconnection with the motive power means. The liquid may be of two colors, one of which is heavier and of greater density than the first, whereby commencement of recirculation will initially pump the heavier liquid prior to pumping of the lighter liquid.
