Water spins down a drain in different directions

Plumbing Trivia: The notion that water spins down a drain in different directions depending on which hemisphere we happen to be in is a myth. The Coriolis force (an apparent force as a result of the Earth's spin) is much too weak to have any affect on small, short-lived rotating bodies of water. Instead, any small irre...gularities in the shape of the drain will determine which direction the circulation occurs.
