Lol - that would be an interesting lecture... maybe it could be used to try to demonstrate the Coriolis force or something (the whole 'the Coriolis force means that water always drains anticlockwise in the Northern Hemisphere' theory... which isn't actually true anyway)?
It's funny you say that, because I was just researching that very thing! (mind thinking on a similar direction!) Most of the reliable stuff out there says no it's not true, the water in the toilet bowl - opposite directions/opposite hemisphere thing.
However, when I was in Brazil back in 1985-86, in the periphery of my consciousness, I kept noticing something was
different whenever I flushed - before finally realising the water was spinning down the bowl in a different direction than that to which I was accustomed. And I asked my friend there, who had also lived in the US, & she said that yes it did. Now I want to know why it did - if the Coriolis-toilet bowl thing isn't true?!
I swear that I saw it. Is it just different plumbing systems or something?
Just further going to show how obsessed we Americans are with toilets!
