The present disclosure provides a portable wireless electroshock device. The portable wireless electroshock device includes (A) a fluid reservoir containing a conductive fluid and (B) a pump in fluid communication with the fluid reservoir and a terminal having an orifice. The orifice is operable to emit a fluid stream trajectory of the conductive fluid there-through, and the terminal is operable to deliver an electrical current through the fluid stream trajectory.

A gas powered fluid gun for propelling a stream or slug of a fluid at high velocity toward a target. Recoil mitigation is provided by a cavitating venturi that reduces or eliminates the associated recoil forces, with minimal or no backwash. By launching a quantity of water in the opposite direction, net momentum forces are reduced or eliminated.
