A golden oldie that appears to have puzzled scientists, Universities, sink manufacturers and laymen alike for Centuries, is WHY water apparently swirls down the plughole anticlockwise in the Northern hemisphere and clockwise in the Southern.

I have surfed the web on this elementary subject until my keys ran hot and have seen it all from complex scientific explanations by Universities, scientists, sink manufacturers and just about everybody from the sublime to the ridiculous, until I ran out of steam. Result ? NONE, totally inconclusive.

Some say that Coriolis has an effect, some say it does not.

If I could see positive information that the majority of people in the Northern hemisphere saw their sinks drain ACW and the majority of people in the Southern hemisphere saw their sinks drain CW, then I would start to believe there is definitely a scientific phenomena present and therefore there must be a scientific solution. Other than that, it is just a myth.

Meanwhile I support this conclusion :-

One can find both counterclockwise and clockwise flowing drains in both hemispheres. Some people would like you to believe that the Coriolis force affects the flow of water down the drain in sinks, bathtubs, or toilet bowls. Don’t believe them! The Coriolis force is simply too weak to affect such small bodies of water.

So what do you think about this schoolboys riddle that has beaten science for a very long time ?
