ABSTRACT:
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.
