Nozzle system and method

A spray nozzle, comprising:

• a rigid rotor in fluid communication with a pressurized air source, wherein the rotor comprises an opening extending through at least a portion of the rotor, wherein the opening is arched or angled such that an outlet of the opening is offset a radial distance in a radial direction from a rotor axis, wherein pressurized air ejected from the outlet, during use, rotates the rotor;
• and
• a hand-held actuator, wherein the hand-held actuator is in fluid communication with the pressurized air source, the hand-held actuator being configured to allow air from the pressurized air source to flow into the opening and be ejected from the outlet.
