Vacuum is a double-barrelled period 46 glider gun that was found by Dietrich Leithner on February 21, 1997. 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 pull blocks and beehives with the tractor beam, as shown below.
