ABSTRACT OF THE DISCLOSURE A symmetrically balanced unitary portable self- contained tool, suitable for single-hand operation, for ejecting a stream of granular particles toward a target site combines a supply hopper containing the granular particles, a portable propellant container carrying compressed propellant liquid, a propellant release valve delivering propellant from the container via a constricted Venturi orifice to a mixing chamber positioned above the uppermost level of particles in the hopper, a delivery conduit connecting the lower portion of the supply hopper to the mixing chamber, and a nozzle connected to deliver a stream of granular particles aspirated from the supply hopper through the mixing chamber by the negative pressure differential created at the Venturi orifice.
