Abstract
A water display which contains a plurality of drip tubes that are suspended from a structure, and periodically drip droplets of fluid in a manner that simulates 'rain fall'. The tubes are attached to a tank that contains a ballast and a volume of fluid. When the water display is off, the ballast is located in an upper position so that the level of fluid is below the openings of the tubes. The display further contains a control mechanism that lowers the ballast into the fluid. Lowering the ballast, displaces the fluid to a level above the opening of the tubes, wherein the fluid flows out of the tank and through the tubes. The control mechanism then raises the ballast to the first position to again lower the fluid to a level below the opening of the tube. The cycle of lowering and raising the ballast is repeated in a periodic manner.
