I thought that clockwise/anti-clockwise thing with the water was a trick. Or a joke, perpetrated by Globetrotters to fool stay-at-homes. I didn't take that question seriously, and I forget how I answered it. The joke version said it was clockwise north of equator, anti-clockwise south or vice versa [I forget], but the fact is, so I was told is that it's the same for both, or varies in both. Sigh. I forget those details too!
Lotsa Joy!
