Not that this has anything to do with either magnetism or coriolis -
but NEITHER of these factors affects the way your water goes down the
drain. Watre is not magnetic, and coriolis acts on far too large a
scale to affect small-scale circulation. The shape of the basin and
any manual force one may exert on the fluid are virtually the only
things that determine whether the imparted rotation is clockwise or
counterclockwise. That's a fact.

Not entirely true. If the basin is perfectly symmetrical and the
water is allowed to dampen out all vortices from the filling process
(i.e. allowed to rest for a day or two) the Coriolis Effect does make
it drain counterclockwise. It works the same way all over the globe.

Doesn't water going down a drain form a vortice that spins clockwise in the
northern hemisphere and counter-clockwise in the southern hemisphere?

You got that right Ace.
