ABSTRACT:
The musical water tank contains, from top to bottom, a tank filled with different fluids, a nozzle member, a washer, a partitioning platform having physically insulated top and bottom halves, and a base having musical sound and light generation mechanism. A pump member and a driving member are aligned and positioned in the top and bottom halves of the partitioning platform, respectively. A motor of the driving member spins a first disc which indirectly and magnetically engages a second disc on an axle of the pump member to spin. The axle of the pump member drives a vane wheel to pump fluid upward into the nozzle member. The fluid is then ejected out of a number of nozzles of the nozzle member into the tank to create visually appealing streams and bubbles, accompanied by the musical sound the lighting effects from the base.
