Flushed

In case you're wondering - and I bet you have been for a while now - our toilet down here in Argentina flushes in a counter clockwise direction. However, it does this not because of the Coriolis Effect (the effect of the earth's rotation on things like bathwater, which, if applied to a toilet, would cause the water to spin in a clockwise direction in the southern hemisphere), but because the water squirts down the right side of the toilet bowl, forcing the water to spin counter clockwise.

So, over the last few days, rather than relying simply upon the limited sampling of our toilet, I took a few hours to use the bathroom in as many restaurants as possible. Of the 24 restaurants I visited, 7 of the toilets flushed clockwise, while 14 of the toilets flushed in a counterclockwise direction. Two of the restaurants were staffed by assholes who wouldn't let me use the bathroom, and one had a toilet that I couldn't get to flush at all.

My conclusion (unless you all can prove otherwise by flushing and posting) is that the Coriolis Effect has no effect on toilets, which, due to their design by Argentine manufacturers, tend to flush in a counterclockwise direction.

A better test might be the draining of our bath tub, but I imagine it will be harder to test other tubs around town.
