Water goes clockwise down the plug in the North hemisphere and anti in the south. What happens on the equator?
Contrary to one of the earlier answers it is NOT an urban myth On one of the Michael Palin Pole to Pole episodes he conducts a rather simple experiment whilst standing directly on the equator He floated a small stick in a container thet had a hole in the bottom to allow the water to drain, by moving a few hundred yards either side of the equator the stick rotated in either a clockwise or anti clockwise direction (dependant on whether he was south or north of the equator) but when stood on the equatorial line itself the water just drained out and the stick did not rotate in any direction
