air_bubbles is a static non-solid point entity that continuously creates small blue air bubbles that slowly rise up.

Usage

Simply put air_bubbles in the map. The bubbles travel upwards a distance of around 200 units and disappear. If placed in shallow water, they don't disappear on the surface and will continue floating in the air. These air bubbles do not appear in Deathmatch, regardless of spawnflags. Can be killtarget'ed.

The first use of it in the game is in E1M4, grabbing player's attention to swim down to the underwater building with Super Nailgun. Another (and last) use of it is in E2M3.
