Abstract
A water display with multiple characteristics, providing a short burst of water or a steady stream of water of constant or variable height. The water display includes an interior cavity having a nozzle at the top for forming the desired stream size, and a flapper valve on the bottom through which the chamber may refill with water. A high pressure air line controllably provides high pressure air to the lower part of the chamber to force most of the water in the chamber out through the nozzle to provide a short blast of water to a height controlled by the air pressure. A second flapper valve, coupled to the chamber, allows a steady stream of water to enter the chamber and exit the nozzle from a water supply, typically a variable pressure water supply, so that a steady stream of water of variable and controllable height may be obtained. Use of the water display in plurality in coordination of the multiple modes of operation thereof provides a new visual effect. Various embodiments are described.
