Abstract Water displays utilizing laminar flow streams to create dynamic arch-like displays are disclosed. The laminar flow nozzle is mounted on an assembly for changing the angle and repositioning the laminar flow nozzle so that the laminar flow stream appears to eminate from a fixed location at different angles, which allows varying the characteristics of the display in a dynamic manner. Simultaneous control of the nozzle position and angle with control of the pressure of water supplied thereto allows the stream to be varied to create a dynamic display with the stream returning to a sink region at a fixed position independent of the height of the water stream. Illuminating the laminar flow stream internally causes the same to glow like a fluorescent tube with the color being supplied thereto, changeable as desired. Intersecting laminar flow streams provide interesting water formations, with the intersections of two streams of different colors causing still a third color at the flared region of the intersection. Features of the invention are useable independently, all in the same apparatus, or in various combinations as desired.
A water display comprising; a source of water under pressure; first and second laminar flow nozzles disposed at different locations operatively connected to the source of water, the nozzles each having an outlet adapted to direct a substantially laminar flow stream toward the laminar flow stream of the other nozzle to collide therewith for viewing by observers of the water display, the laminar flow stream of each nozzle having a predetermined trajectory projected at a predetermined angular elevation; and light source means disposed in said laminar flow nozzles for directing light substantially along an axis essentially parallel with each laminar flow stream emitted thereby, said light source means being adapted to direct a different color along each laminar flow stream, wherein said laminar flow stream of said first laminar flow nozzle has a first color and said laminar flow stream of said second laminar flow nozzle has a second color whereby the laminar flow streams will appear illuminated along at least a substantial part of their length and said first and second colors combine to create a third color where said laminar flow streams collide.
