You might have heard about the myth that the direction of rotation of a bathtub or toilet vortex is determined by the hemisphere it happens on. It is said that toilets and bathtubs drain differently in the Northern (i.e. Sweden) and Southern Hemispheres (i.e. Australia). Although theoretically Coriolis forces (category of gravitational forces) affect the draining flow, practically, there are many other stronger factors, such as turbulence, temperature distribution that dominate.
In 1908, the Austrian physicist Otto Tumlirz have done some experiments which demonstrated the effect of the rotation of the Earth on the outflow of water through a central aperture. He proved that the myth is true in the laboratory, but in real life, other factors are more important. So it is not necessary to see the water in Austalia or any other country of the Southern Hemisphere running the other way from this of the Northern.

I hope I have answered to your question.
Have anybody done this experiment at his school?
