Re: What direction does a toilet flush at the equator?

Here is an answer already posted on our site:

However, I have never been convinced that the direction of the toilet flush 
has anything to do with the rotation of the earth because the water ports on 
the toilet direct the water in a certain direction.  Hurricanes, however, are 
big enough and otherwise undirected that the coriolis "force" does decide what 
direction they rotate.  If the "hurricane" gets started right on the equator it 
is unclear which direction it would rotate.  Possibly as soon as it went north 
or south of the equator it would begin to rotate in the direction of that 
hemisphere.
Try searching for information on coriolis force.

I hope this helps!
