ABSTRACT:
The present invention is an apparatus for creating a "pop jet" type of ornamental fountain with an output stream in the form of surface-tension envelope or "ball" of fluid, embedded with air bubbles. By virtue of the laminar nature of the fluid created, the natural surface tension of the fluid prevents the envelope from flying apart into multiple fluid drops. The envelope therefore can be created much larger than has been possible previously. Previous attempts at building "pop jet" type fountains have been limited to creating relatively small envelopes due to the internal turbulence of the fluid. The present invention minimizes internal turbulence by utilizing various advances in envelope shape, outlet orifice design and diffuser strucutre. It enhances the size of the envelope produced by adding fluid and air bubbles outside the outlet orifice by directing the output stream sthrough a secondary pool of fluid.
