A toy water gun having a housing with extending handle, trigger and barrel, said water gun, comprising:

• (a) at least one water storage reservoir external from and connected to said housing, said reservoir having at least one orifice formed thereon for the addition and withdrawal of water therefrom, and said reservoir having at least one vent to surrounding ambient air so that air may enter said reservoir;
• (b) at least one pressurized air and water storage tank external from and connected to said housing, said pressurized air and water storage tank having only one orifice through which all liquids and gasses pass, the combined total of said at least one water storage reservoir and said at least one pressurized air and water storage tank being at least three;
• (c) a pumping means for withdrawing air or water from said at least one water storage reservoir, and for depositing said withdrawn air or water into said at least one pressurized air and water storage tank;
• (d) a plurality of one-way flow valves, wherein at least one of said one-way flow valves prohibits water and air from flowing from said pressurized air and water tank to said pumping means and another of said one-way flow valves prohibits water and air from following from said pumping means to said water storage reservoir;
• (e) a nozzle having a narrow orifice therethrough, said nozzle being affixed to the end of said barrel;
• (f) an avenue of release connecting said nozzle to said pressurized air and water tank;
• and,
• (g) a controlling means for regulating the flow of water and air through said avenue of release, said controlling means being actuatable by said trigger.
