A fog-cloud generating nozzle is disclosed. In one embodiment, a nozzle head having a fluid passageway is threadable coupled to a nozzle base. The nozzle base, which provides a threadable coupling to a water source, is disposed in fluid communication with the fluid passageway. An inner sleeve is rotationally disposed within the fluid passageway with bearing surfaces against the nozzle head and the nozzle base. Multiple discharge ports of the nozzle head and multiple discharge orifices of the inner sleeve cooperate to generate a fog-cloud having a magnified forward thrust component and enabled directional control.
