For a few different reason that I can't tell you, I put together this package. The idea is a sort of black hole / stasis weapon that cleans up the environment of, well... anything!
The coolest part of this effect, IMO, is what happens behind the scenes. To avoid having every asset flagged as a rigid body which would add tons of CPU overhead, I scripted the system to add a rigid body component to any prop that is within range of the vacuum, on the fly. It worked out shockingly well in the end (yay for Unreal 4!). I`m sure there are better ways to handle that, but I had only a week to put this together and just needed to get it done.
