Boom tube

A Boom tube.

A Boom tube was an extra dimensional doorway used by the New Gods to move through interstellar distances. Boom tubes were activated by Mother Boxes, and could be programmed to transport single individuals, as well as entire gangs and armies. When in use a 'tube' coated in arcane technology appears for the user to pass through accompanied by a loud 'boom' noise (hence the name).
