Claim 18:
19. The water gun of claim 1, wherein the shuttle valve and the integral housing provide deceleration of the shuttle valve prior to the shuttle valve reaching its engaged position comprising:
at least two mechanical impedances defined between the shuttle valve and the integral housing which impede the flow, the at least two mechanical impedances comprising:
a first mechanical impedance defined within a first clearance between a first shaft segment of the shuttle valve entering the integral housing having a first diameter and a first mating segment of the integral housing for restricting flow of water; and
a second mechanical impedance defined within a second clearance between a second shaft segment of the shuttle valve entering the integral housing having a second diameter, the second shaft segment being connected to the first shaft segment, and a second mating segment of the integral housing for restricting flow of water

wherein the first diameter of the first shaft segment is less than the second diameter of the second shaft segment;
wherein the first mating segment and the second mating segment are axially spaced apart;
corresponding first and second mating segments of the shuttle and the integral housing are axially spaced, to act together, providing impedance to flow which decelerates the shuttle prior to the shuttle reaching its engaged position
wherein a volume of water between the first mating segment and the second mating segment is displaced and the volume displaced is proportional to a difference between an area of the first diameter of the first shaft segment and the second diameter of the second shaft segment of the shuttle valve and an axial distance traveled by the shuttle valve;
wherein the first mechanical impedance and the second mechanical impedance decelerates the shuttle valve prior to the shuttle valve being in the shuttle valve engaged position, such that the deceleration is proportionate to the volume of water which was displaced though the first mechanical impedance and the second mechanical impedance and associated magnitude.
