[Source] The adhesive grenade was a type of grenade used during and after the Jedi Civil War, around 4000 BBY. Designed as a method of riot control, the adhesive grenade exploded with an incredibly sticky substance that anchored a target to the ground and slowly dissolved so as not to trap targets for long periods of time. These grenades had a similar effect to the Merr-Sonn G-20 Glop grenade used four thousand years afterward.
