The G-20 Glop grenade was a strange weapon created during the Galactic Civil War. It exploded on contact and sent out a small wave of "glop". The glop attached to solid objects and instantly froze to a solid form. Larger variations of this weapon were used to stop incoming vehicles on the battlefield. These grenades, due to the fact that they release the liquid through jets rather than exploding, can be reused by simply refilling them.
