Abstract: A laminar flow liquid stream nozzle having capability of being mounted to project a stream in any direction including directly overhead and including a stream capturing device for making the stream seem to disappear when projected overhead. The nozzle is selectively capable of momentary stream bursts or timed periods of projection from short periods to continuous stream flow. A structure of multiple such nozzles is provided having at least two banks of oppositely located spaced receptacles with essentially linear laminar flow stream patterns each projected unidirectionally from a nozzle in one receptacle to a receiver in another receptacle. The structure may include vertical linear stream patterns. These patterns may include parallel laminar jet streams and some may be projected straight up. Turning a vertically directed stream "off" may be achieved by a splitting water spray which causes split stream portions to be intercepted by surfaces within the nozzle near the normal "on" laminar flow stream path.
