An ornamental fountain nozzle has no moving parts and includes a hollow body defining an internal chamber having a liquid inlet at one end thereof and an outlet opening at its opposite end. The communication between the chamber and the outlet end of the body is via grooves formed in a plug disposed across the outlet end of the body and having substantial length between its opposite end surfaces. The net area available for water flow out of the nozzle through the grooves is less than the area of the liquid inlet to the chamber.
