Do toilets flush different directions on the northern and southern hemispheres?

Not really... A misconception continues to propagate in popular culture, that the Coriolis effect determines the direction in which bathtubs or toilets drain, such that water always drains in one direction in the Northern Hemisphere, and in the other direction in the Southern Hemisphere. Several science broadcasts and publications (including at least one college-level physics textbook) make the misunderstanding. Many people who misunderstand the Coriolis effect compound their misunderstanding by incorrectly claiming that drain water spins clockwise north of the equator, and counterclockwise south of it, which is reversed from direction of spin that would result from the Coriolis force if it were a determining factor.
