Vacuum is a double-barreled period 46 glider gun that was found by Dietrich Leithner on February 21, 1997.[1] It uses three copies of twin bees shuttle stabilized in various different ways to produce the stream of gliders. Its name comes from the fact that it can be extended and used to pull blocks and beehives, as shown below.
