The water will go down the toilet in the opposite direction. You'll
have to use your starter to turn off your car.

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?

Oh yeah. At the equator no twist, the force is zero.

This is true, but again, only on large scale circulation - not on sinks
and toilets.

The scale does is not a factor of the Coriolis force. The magnitude of
the force is constrained by latitude and speed of matter. It is a force
stemming from the inertia of mass having a rotational spin placed on it
by the motion of the earth so it affects all matter even the water in
your sink.

If you don't believe me then you can do this experiment yourself. Fill a
sink with water and after it is very still open the drain without
disturbing which way the water spins down the drain. Do it a couple of
times and you will notice a tendency for the water to spin clockwise.

H-Y-P-O-C-R-I-T-E ALERT!!

No, it doesn't. The coriolis effect at the scale described by dxAce is
too small. This is one of those scientific myths that die REALLY hard.
