Abstract
A water gun may comprise a body having a front surface, a nozzle mounted on and extending from the body, an actuator, at least one fluid reservoir, and a pump. The nozzle may have at least a nozzle portion adapted to move between an extended position spaced away from the front surface and a retracted position closer to the front surface than the extended position. The actuator may be adapted to be moved relative to the body, and mechanically coupled to the nozzle for moving the nozzle between the retracted and extended positions when the actuator is moved between first and second positions. The fluid reservoir may comprise first and second end portions and a generally uniform elongate intermediate portion extending between the first and second end portions, which may have volumes that are larger than the volume of the intermediate portion. The pump may be fluidly coupled to the at least one reservoir and the nozzle, with the pump being operable to discharge fluid received from the at least one reservoir through the a nozzle.
