Hi,
hubby is going to sydney on tuesday - biggest problem is people have showers in oz rather than baths, but i will ask for a scientific experiment in the sink re which way the water swirls
regards
ela

It's not to do with magnetism even if it IS true.
I've just tried it in my bathroom sink, and it depends entirely on which way the water is swirling to start with. If I don't swirl, it just goes straight down. Perhaps your sink has a drain pipe which favours drainage in one direction. I'd bet a tenner that it's 50/50 if you try a random selection of sinks!
Given the speed the earth rotates (ie 1 revolution every 24 hours) I really can see no phenomenon related to magnetism, gravity or anything else which would provide enough of a force to make any difference. If you work one out, let me know as it could be a great way to generate free electricity.
Regarding the video, you can make the demonstration show whichever answer you want. The guy slooshes the water round all over the place, and any force from the Coriolis effect is going to be swamped by all the other stuff going on.
Also, just because the BBC have shown it doesn't mean it's true, minty! It was on Pole to Pole; I didn't believe it then and I don't now.
See the Wikipedia article for further debunking of the myth, as well as calculations which show the magnitude of the force is tiny.

Oh, by the way, if it WAS the Coriolis effect causing this, then it'd be the other way round - counter-clockwise in the north.

It's a fraud...
