Sitting in a tub of water and farting while squeezing your legs together and trying to keep the fart bubble from coming out below your knees.By carefully raising or lowering your legs you can actually contain the bubble midway between the anus and the knees,thus attaining level.
Doing the carpenter's level in the tub is almost like playing one of those B-B in the maze games.
