Abstract
A water gun (10) is provided having a pressure tank (19) in fluid communication with a coupler (20) adapted to be received upon a conventional water faucet, and a pump (42) for conveying additional air to the pressure tank. The flow of water from the water faucet draws ambient air which is compressed within the pressure tank to pressurize the water therein. The pressurized liquid is released through a nozzle (21) coupled to the pressure tank by actuation of a trigger (17).
