Many people think that water draining from a sink rotates in a particular direction due to something called the Coriolis effect, which is generated by the rotation of the earth. Furthermore, such people frequently argue that the direction of water flow is reversed in the opposite hemisphere. In reality, the Coriolis effect in that situation is too small to affect the direction water drains from a sink or toilet. The drainage direction is instead related to the shape of the sink bowl or the direction water flushes into a toilet.Which statement best describes science?
