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.

[ What is claimed:] [1.] A water display comprising:a tube structure having a nozzle at the top thereof for placing in a pool of water;a controllable source of water coupled to the tube structure to controllably force water into the tube structure to expel water from the nozzle;a controllable source of air under pressure coupled to the tube structure; and,a first valve coupled to the tube structure, the first valve opening in response to differential pressure to allow water flow into the tube structure from a surrounding pool of water and closing to prevent the flow of water from the tube structure to a surrounding pool of water.
