Water Experiment

Everyone knows that if you fill the bathtub with water and start to pour it, the swirl of the water in the Northern Hemisphere will twist counterclockwise, and in the South - clockwise (the Coriolis effect). During the fasting experience by the author (location Moscow - Northern Hemisphere) with a friend in Perth, Australia - Southern Hemisphere, it has shown that the statement does not always work. This is due to the fact that the Coriolis force caused by the earth's rotation acts on tightening the water, but she was too weak to change the direction of the drain in the water, and to a greater extent associated with the construction of the drainage system of the house, but in this video is very clear.
