Abstract
A toy that can sense contact with a fluid. The toy preferably contains a conductive member and an adjacent conductive screen. An indicator circuit has one terminal connected to the conductive member and another terminal connected to the conductive screen. The screen and conductive member are in relative close proximity so a fluid which flows through the screen will provide an electrically conductive path between the two conductive members. The conductive path closes the indicator circuit. The indicator circuit has an audio unit and/or light source that are activated when the circuit is closed by the fluid. The conductive members can be attached to a shield which also has a spray device. A player can spray another player with the spray device of the shield. The player can also block the spray of an opposing player with the shield. If the fluid makes contact with the conductive members the indicator circuit provides an indication that a "hit" has occurred. A player must therefore expose himself to a possible hit when attempting to spray another player. The toy may have a counter which shuts off the spray device if the player has been hit a certain number of times.
