Here are My facs to this topic:
Location: Amsterdam - Well on the northern hemisphere
Lived there for seven years. Bathtub drains COUNTERCLOCKWISE.
Every single time. I verified it a lot of times, yep, COUNTERCLOCKWISE.
Now I moved to a new location:
Sydney, Australia, obviously southern hemisphere.
I live here for seven months now, and I have a very similar bathtub in my house.
Water drains CLOCKWISE. Every single time. Just tested it again.
Again, CLOCKWISE.
I verified it visitin Europe again, also at my parents place, its counterclockwise, and at friends Places here in Sydney, it just is clockwise.
So? What about urban myths and debunking?GW
