A toy water gun for projecting a fluent material. The gun has a front gun body and a rear gun body, one having a cylinder as a part thereof and the other having a piston as a part thereof. The piston is slidable in the cylinder for both expelling water from the chamber defined by the cylinder and for drawing water into the chamber. A first one-way valve at the nozzle closes when the gun bodies are moved away from one another. A second one-way valve is provided on the piston or cylinder of the rear gun body which employs an additional stop for temporarily restraining movement of the valve body. A suction conduit is connected to the second one-way valve of the rear gun body which is held in a lowered position by the a spring.
