each player one form of which is illustrated in fig6 alternatively disappearing ink could be used instead of water so that no target in necessary now referring to fig7 an alternate embodiment of the marker tag gun may be seen in this embodiment the water output tube 66 does not go directly to needle 64 for loading the marker tag dart 62 but instead goes to a valve 69 which controls the flow of water in the water output tube 66 in particular when in position 1 as shown the water pumped by the initial pulling of the trigger is provided to the marker tag dart 62 through needle 64 prior to releasing the marker tag dart 62 as in the previously described embodiment when valve 69 is in the second position water flow is blocked so that the marker tag dart 62 will be released without having supplied water to its forward tip in that regard water pump 48 is a rather leaky pump so that the trigger 42 can still be pulled even though water flow is blocked when valve 69 is in the third position water is supplied not to the tip of the marker tag 62 but rather through tube 70 to output nozzle 72 to shoot a stream.
