G-20 Glop Grenade
manufactured by Merr-Sonn, these detonation devices release a chemical foam when triggered. The foam has incredible adhesive properties, and clings to everything it touches. When lobbed into a mob or battle phalanx, glop grenades can quickly immobilize attackers. It required a special "glop dissolver" agent, often in aerosol form, to remove the glop. Because these grenades didn't exploed so much as crack open, the shell could be recovered and cleaned for reuse.
