Abstract
A whistling spinning grenade has a body defining a body axis and having a sidewall and a hollow interior, the body interior containing a teargas generation component and an ignition component, the body sidewall defining a plurality of passages, each passage communicating from the interior of the body to an exhaust aperture, each exhaust aperture penetrating the body sidewall and defining an exhaust aperture axis, and each exhaust aperture axis being angularly offset from a radius connecting the passage to the body axis, such that it has a tangential directional component with respect to the sidewall, and wherein rotation of the grenade about the body axis is propelled by the expulsion of exhaust gas through the exhaust apertures. The teargas generation component may be proximate the ignition component such that combustion of the ignition component ignites the teargas generation component. The passages and exhaust apertures may be all coplanar.
