A water globe arrangement includes a fluid pump immersed in a fluid within the fluid-containing glass dome, the fluid pump drawing fluid in through a fluid inlet and expelling the fluid through a fluid outlet, thereby circulating the fluid and creating a visual movement effect within the glass dome. In one aspect of the invention, a glass dome is filled with water and contains a number of small free particles having a specific gravity greater than that of the water. Upon activation of the fluid pump, a continuous flow of circulating fluid keeps the free particles in constant motion within the glass dome. In another embodiment of the invention, the fluid pump forces fluid within the glass dome along an elongated passageway coupled to the pump fluid outlet for directing the flow of fluid to a location remote from the fluid outlet. In such an arrangement, the fluid exiting the elongated passageway may be located above the level of the fluid within the glass dome and simulate the flow of lava from a volcano structure situated within the glass dome. Alternatively, the passageway may exit at or near the fluid level within the glass dome and simulate a bubbling brook, hot springs, or the like.
