A rotatable fountain display device rotatably displays an indicia, such as advertisement over a fountain. The device comprises a plurality of spheres immediately adjacent and sequentially connected to each other to rotatably display an indicia, such as an advertisement. The device works in conjunction with a fluid source, such as a fountain, to receive a fluid carrying a fluid pressure. A lower sphere contains a rotation mechanism that harnesses the fluid pressure from the fluid source to generate rotational energy on the lower sphere, which then rotates sequentially connected middle and upper spheres. A central channel runs through the spheres. A nylon elastic member and a rubber band interconnect the spheres and enables multidirectional movement by the spheres. A guide wire passes through the spheres to help counterbalance the movement. An annular bearing apparatus restricts rotation of the central channel and reduces friction during rotation of the rotation mechanism.
