    It's down under... surely the water should pour out of the plug hole.
    Everything is self-evident.

        According to the Scientific American, the following is the explanation:

        "The tendency of a circulation in a fluid to develop in a clockwise direction in the Northern Hemisphere and a counterclockwise direction in the Southern Hemisphere can be traced to the earth's rotation. Imagine a cannon fired southward from any latitude above the equator. Its initial eastward motion is the same as that at a point on the spinning earth. This initial eastward velocity is less than that at a point later in its trajectory, because points closer to the equator travel in a bigger circle as the earth rotates. Therefore, the cannon shell is deflected westward (to the right), from the perspective of a person standing on the earth. A gunner firing a cannon northward would find that the shell is also deflected toward the right. These sideways deflections are attributed to the Coriolis force, although there really is no force involved--it is just an effect of being in a rotating reference frame.

            Thanks for that Vico - so what happens if you're living on the equator - does the water just pour straight down the plug hole without any circular motion ?

                Ceremonies aboard ships to mark a sailor's or passenger's first crossing of the Equator, as well as crossing the International Date Line, have been long-held traditions in navies and in other maritime services around the world.

                    Tanoa International Dateline Hotel offers accommodation in Nuku‘alofa. Located on the waterfront, guests can enjoy the on-site bar.

                            I was looking at a Grandpus in the Atlantic near Cape Verde last week.
                            I google because I'm not young enough to know everything.
