Hi,

I'm having some questions about this effect.

Please watch the full video below to understand, video starts at 30s:



In the video you can see that this effect only happens when the earth is rotating and the poles oppose eachother.
It's required that the poles oppose eachother, otherwise there won't be a difference where you are on earth. Water would just move faster when you are at the edge.

How would such effect be possible if the earth is another shape than a globe (or globe like shape)?
