A decorative and educational waterfall device has a substantially continuous film of a liquid, such as water, low viscosity oil or an aqueous solution, extending between two vertically upstanding guides. The waterfall comprises a base reservoir in which is mounted an electrical pump. A tower containing a liquid flow passage is mounted to the base and a trough having two side walls and a bottom wall which terminates in a lip portion at the front edge of the trough is mounted to the tower so that liquid from the tower flows over the bottom wall and lip portion of the trough to form the waterfall between the two upstanding guides. One or more flow restrictors are mounted transversely across the trough, substantially parallel to the lip portion to decrease the turbulence of the flowing liquid and improve the capability of the liquid to form a continuous film.
A device for forming a waterfall comprising a source of aqueous liquid, two upstanding liquid guides arranged in spaced relation to one another, said liquid guides having upper and lower end portions, a trough mounted adjacent the upper end portions of the liquid guides, a liquid flow member connected between the source of aqueous liquid and the trough, said trough having a lip portion over which aqueous liquid from the source of aqueous liquid flows in an aqueous liquid path in contact with the guides to form a substantially continuous aqueous liquid film extending between the liquid guides from the lip portion of the trough to the lower end portions of the guides, said liquid flow member comprising at least one of the liquid guides.
