Down the Plughole
The Earth's rotation is anti-clockwise as viewed from the North Pole.
Water swirls down the plughole anti-clockwise in the Northern hemisphere and clockwise in the Southern hemisphere. Well - does it ?
I am assuming that water swirl is entirely caused by the Earth's rotation and gravity. I see no other parameter. Coriolis effect is not applicable since the volume is far too small.
So why do you think that water goes down the plughole anticlockwise as viewed in the Northern hemisphere and clockwise as viewed in the Southern hemisphere ?
