Is there any simple way of using the Coriolis effect to determine what hemisphere you are in? I have heard from many people that sinks do not empty in a particular pattern depending on what hemisphere you are in, but I have also heard from people who adamant that a sink of water would empty clockwise in one hemisphere and anti-clockwise in another.

While I acknowledge the above idea is probably a myth, is there any simple experiment that one can do do determine what hemisphere they are in, utilizing the Coriolis effect, or otherwise?
You can use the Foucault pendulum to determine the hemisphere: Its plane of movement rotates:


anti-clockwise in the southern hemisphere;
clockwise in the northern hemisphere. 


The rotation of the plane can be explained by the Coriolis force.
