Abstract
A water device that can display predetermined patterns that form letters, numbers, pictures or other visually apparent figures. The water display has a shallow pool of water with a flat bottom surface, that has a plurality of holes spaced apart in a grid like fashion. The holes are connected to a source of air that introduces bubbles into the pool. The air exits the water in such a manner as to leave a visually distinguishable mark or impression in the pool. The bubbles are combined and patterned into an identifiable figure such as a word or a set of numbers. Each hole has a solenoid valve that allows air to flow into the pool when the solenoid is energized. The valves are connected to a computer that selects which holes are to release air and when the bubbles are to be released. The actuation of the valves can be selected and sequenced in accordance with the operating instructions of a computer program, that produce a pattern of bubbles to create the desired form on the surface of the pool.
