Claim:
A stun grenade comprising: a canister; a compressed gas source installed within the canister supporting gas flow at a predetermined minimum rate; an inflatable bag having a target pressure and a target volume to initiate a shock wave of an intensity selected to achieve a minimum noise intensity at a prescribed distance upon rupture; the inflatable bag incorporating a seam which parts at a tension and extension occurring at the target pressure and target volume to produce the rupture; a conduit connecting the compressed gas source to the inflatable bag; the compressed gas source supporting gas flow to the inflatable bag through the conduit at a predetermined minimum rate to achieve the target pressure and volume for parting the seam within a fixed period; a valve in the conduit for controlling discharge of gas through the conduit from the compressed gas source to the inflatable bag; and a manually actuated external trigger installed on the canister to activate the valve to discharge gas to the inflatable bag.
