- "You got yourself caught in the zero gravity trap?"
- "I don't know what you call it, man. I... Oh!"
- —John Constantine and Gary Lester[src]
Zero gravity trap is a type of a magic spell which creates a small zone of zero gravity within a certain place.
As Gary Lester lock-picked his way into the millhouse, trying to meet with John Constantine, he somehow activated the trap, ending up being in it for hours before John Constantine and Zed Martin returned, freeing him.
- It is unknown how exactly the trap is triggered, but it might be assumed that it is somehow connected to the lock as the only time it caught someone was in case lock-picking.
