ABSTRACT OF DISCLOSURE The present invention is directed to a toy water gun which is operated by selectively releasing water from a pressurized water reservoir. The present invention has a manually operated pump incorporated into the design. As the pump is cycled, water and/or air are drawn from at least one water storage reservoir. Once drawn, the water and/or air are forced into at least one pressure tank. As the amount of water and/or air forced into the pressure tank increases, the pressure of the air displaced by the water within the pressure tank increases. The pressure of the air on the water within the pressure tank increases with each cycle of the pump, until the pump can no longer overcome the pressure of the air of the water within the pressure tank. The pressurized air and water within the pressure tank has an avenue of release that is regulated by the trigger mechanism of the invention which has a safety pressure release within its design. When no force is applied to the trigger, the pressurized water and air are held at bay with no means of release. When force is applied to the trigger, the heavier water is first released from the bottom of the pressurized tank and is channeled through a narrow nozzle. The escape of the pressurized water through the narrow nozzle creates a stream of propelled water that lasts as long as the trigger is engaged or until the pressure within the pressurized tank equals the ambient air pressure. The number of water storage reservoirs and pressure tanks combined totals at least three.
