Many friends have asked me to flush the toilet while in the Southern Hemisphere and report back on the direction of the flush. They believe it will flush the opposite direction as the Northern Hemisphere. Really?
I have confirmed the myth is false! Not only have I observed it personally, the science does not add up. The Coriolis effect is more relevant to weather than toilets. Watch this video for a longer explanation.
Even astrophysicist Neil deGrasse Tyson weighed in on the subject:
Toilet Bowls drain however they’re designed to circulate water. It’s irrelevant whether you live above or below the equator.
