Abstract

A toy grenade, designed for launching large numbers of plastic BBs at once, consists of a cylindrical shell with an O-ring interface. The cylindrical shell has circumferentially angled guide portions that allow the O-ring to flex inwardly when moved towards the remote ends. As a result, users can safely unload all the BBs if they wish to do so.
