Abstract: A floating rotatable fountain decoration having a basin, an agitator, a water pump, and an ornament wherein the water pump is employed to suck water within the basin for creating a circulating flow of water that passes through the agitator to impart rotational motion to its blades, thereby producing an eddy that brings the ornament floating on the surface of water within the basin in rotation. Meanwhile, the flow of water passing through the agitator is finally spouted out through nozzles upwardly to the ornament, thereby creating a fountain effect. Moreover, the fountain spouted to the ornament flows back to the basin, thereby producing a dynamic visual effect. Accordingly, three effects of floating rotation, fountain and flow of water can be combined in a body by simple mechanical means.
