Knock-down test of a 109 mph (175 km/h; 49 m/s) vortex ring gun. The vortex ring gun is an experimental non-lethal weapon for crowd control that uses high-energy vortex rings of gas to knock down people or spray them with marking ink or other chemicals. The concept was explored by the US Army starting in 1998, and by some commercial firms.
