A toy water gun has a hand pump for pressurizing a reservoir of water and a trigger which controls a valve for allowing pressurized water to squirt from a nozzle when the trigger is pulled. A spring wire which normally urges the trigger toward a rest position engages a contact in response to pulling of the trigger whereby a circuit is completed to energize a motor which drives a slider-crank mechanism for causing reciprocation of the water gun's barrels, and to energize a sound circuit for simulating the sounds of gun fire.
