A fountain device with a rotating revolver consists of a reservoir, a water supply system, at least one bearing system, and at least one revolver. The water supply system is secured in the reservoir and pumps water to rotate the revolver and to spurt the water from a top of the revolver. The mounted revolver(s) are rotated by hydraulic power, and can selectively rotate the demanded revolver by setting a bifurcating box and the bearing system between a bottom board of the demanded revolver and a revolver below the demanded layer. The structure of this invention enables it to be used indoors, outdoors, or even on a table.
