An improved manually operated plant watering device is provided for watering plants in hard to reach places. The plant watering device includes an elongate hollow tube, flexible hose, and nozzle. Located within the hollow tube is a piston manually controlled by a handle for drawing water to within the elongate hollow tube or for projecting water from the elongate hollow tube through the flexible hose and nozzle. In a preferred embodiment, the plant watering device includes an extension pipe for extending the overall length of the plant watering device. Furthermore, preferably the plant watering device includes an impedance valve for impeding unwanted flow of water from the plant watering device.

The air cap of claim 12 wherein each air horn has two parallel passages and one non-parallel passage. 14. A spray gun system comprising: a gun body adapted to receive a pressurized fluid and discharge the pressurized fluid at a nozzle end; a nozzle assembly connected to the nozzle end of the gun body, the nozzle assembly including an air cap having a pair of non-circular apertures on an inside surface of the air cap, each non-circular aperture in communication with a plurality of discharge apertures discharging pressurized gas toward the pressurized fluid to form a generally oval-shaped spray pattern; and wherein an inlet of each non-circular aperture has a boundary defined by an arcuate shaped wall connected to one or more linear shaped walls. 15. The spray gun system of claim 14 wherein the air cap includes a pair of air horns extending outwardly from the air cap, wherein each air horn includes a plurality of passages having openings that are directed generally perpendicular to the non-circular aperture to discharge pressurized gas from the nozzle assembly toward the pressurized fluid. 16. The spray gun system of claim 15 wherein each air horn includes at least one passage that is non-parallel to the plurality of passages that are directed generally perpendicular to the non-circular aperture to direct a portion of pressurized gas in a different direction. 17. An air cap for an air-assisted spray nozzle assembly, the air cap comprising a body having a cylindrical sidewall and an end wall connected to the cylindrical sidewall, the end wall having an inside surface, an outside surface, and at least one aperture therein, the inside surface of the end wall having a non-circular opening in fluid communication with the at least one aperture, and the outside surface of the end wall having a plurality of openings in fluid communication with the at least one aperture, wherein the non-circular opening is defined by an arcuate wall contiguous with the cylindrical sidewall, a pair of opposing sidewalls extending inwardly from the cylindrical sidewall and a wall connecting the pair of opposing sidewalls. 18. The air cap of claim 17 wherein the wall connecting the pair of opposing sidewalls forms a 90° angle at the connections. 19. The air cap of claim 17 wherein the at least one aperture extends into an air horn having the plurality of openings therein, wherein the plurality of openings have a discharge end that is substantially perpendicular to the inside surface. 20. The air cap of claim 19 wherein the plurality of openings have passages in communication with the at least one aperture wherein at least one passage is non-parallel to another passage. 21. A nozzle assembly connected to a gun body, the nozzle assembly including: an air cap having a pair of air horns disposed on an outside surface of the air cap, wherein each air horn has a discharge opening; the air cap further including an inside surface having at least two non-circular apertures, each non-circular aperture in communication with an air horn discharge opening; and wherein each non-circular aperture has a cross-sectional shape symmetrical with a cross-sectional shape of an air horn.
