TG,
It is a well-known Scientific fact down here, that water circles the drains in an opposite direction to the Northern Hemisphere.
Don't ask me why, those are "just the rules"!. [Linked Image]
Drain a bath or a Kitchen sink and you will see the water spiral in a Clock-wise direction.
I've never been to the Northern Hemisphere to try that concept out, but if I was there, I'd usually have more important things on my mind!. [Linked Image]
