ROTD Riddle of the Day

Sue is traveling by ship from south of the equator to the north.
She has a nice little cabin with a bathroom, but no window.
Sue has no compass nor other instruments. Just the general luggage one brings on board a long cruise. Yet, without leaving her room or talking with anyone, Sue will be able to tell when the ship has crossed the equator. How?

When she flushes the toilet, or lets water run down the drain, the water will go down in the opposite direction.

Okay, I really have to take back the answer I just posted to this question. Apparently my thoughts were based on utter nonsense, though commonly believed.

Dennis this is the answer I had...

Sue can fill the sink and watch it drain. When the water reverses direction when going down the drain, she will know they have crossed the equator.
