Abstract: Embodiments of a water gun are provided, which may include a body, further including a reservoir for holding a fluid, a nozzle for ejecting fluid, and a shield mounted to the body; a pump assembly operable to move fluid from the reservoir to the nozzle, and a hand-operated crank assembly rotatably coupled to the body. Rotation of the crank assembly may operate the pump assembly to eject fluid from the water gun. In some embodiments, the shield is pivotably or foldably mounted to the body and may be retained in one or more selected positions perpendicular or parallel to the body of the water gun, which may allow a user to deflect fluid streams ejected from other water guns. In some embodiments, a plurality of nozzles is provided, each of which may be selectively operated exclusive of the other nozzles or in combination with other nozzles.
