[Central Scrutiniser]

For that matter some "science" teachers have taught that toilet bowls flush one way in the Northern Hemisphere and the other way in the Southern Hemisphere.

Once, on a flight from LA to Lima, Peru, I went to the bathroom as we were transiting the equator. I flushed, wanting to see which way the water would flow. But, you know, them damned 767's and their suction toilets! FWIW, the water in the sink went straight down, but hardly a scientific laboratory!
