The Void Unfolder. This is the end point in evolution for a device that could harness nothingness, compress it into a small payload that would then "unfold" on contact with solid matter or after a short delay. The Void Unfolder is a weapon that does this especially well. with it void reservoir, you fill it in with emptiness and you're set for a good while.
The trigger shoots a payload while the thumb roller lets you control the volume of void to shoot out. when a payload hits solid matter (it manages to pass through both gaseous and liquid matter), it immediately unfolds space. This is empty space, no gas, nothing. This naturally causes some pretty destructive warping to begin with, but if it's shot in an environment within an atmosphere, the vacuum fills itself with a loud pop, further ripping apart matter around the impact point.
and do keep in mind, it creates empty space, so the actual radius warped by it is much bigger than the pocket it creates, bending space around the impact point.
