The Ethereal Bomb or Ether Bomb for short, most feared weapon the Ghostbusters ever designed. Also known as an Ghost Bomb, this weapon has one sole purpose; to disintegrate all ectoplasmic entities in a fifteen yard radius, ripping their ectoplasm apart molecule by molecule within seconds until there nothing left. It is done by super energize the mutated tissues inside bomb’s four containers until they reach critical mass that results into hyperspace implosion that will ripple through the ethereal plane thereby causing hyper accelerated ectoplasmic decay by every ectoplasmic entities, disintegrate them in its wake of the explosion. 
The Ghostbusters only use these weapons as last resort.
