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 intersection 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; a laminar flow nozzle disposed to direct a laminar flow stream of water therefrom in a trajectory for viewing by observers of the water display; and, control means for controllably varying the trajectory of the stream of water by varying the position of said laminar flow nozzle simultaneously with the variation of the angular elevation thereof, whereby the laminar flow stream will pass approximately through a first fixed point in space spaced from said laminar flow nozzle outlet independent of the reasonable variation of the local angular elevation of the laminar flow stream, whereby a dynamic water display is created.
