Debunking the Toilet Myth

At one point or another we have all had this thought cross our minds Why does the toilet water spinĀ  clockwise as it flushes? Interesting question. Chances are you have probably heard the very interesting answer. It flushes clockwise in the Northern Hemisphere, but counter-clockwise in the Southern Hemisphere because of the Coriolis Force.

The Coriolis Force

The Coriolis force stems from the spin of the Earth. Because the spherical world turns on its axis, a floating object pushed in a straight line will appear to veer to the right. If you imagine standing in the Northern Hemisphere facing South and push a floating object due South it will veer West because the Earth beneath it is always moving and as you move closer to the equator, the world becomes wider in diameter.

It is nearly impossible to notice over small distances, but if an object is pushed far enough, the effect can be measured. This (supposedly) applies to toilets because in the northern hemisphere, the water on the northern end of the toilet has less distance to travel than the southern end. As a result, the water spins clockwise in the Northern Hemisphere and opposite in the Southern.

In truth, a toilet would need to be well over a mile wide to be affected by the Coriolis Force.

So Why Do Toilets Flush Clockwise?

Well, the truth is that not all of them do. Also the reason for the direction of their flush is much less exciting than the force of the Earth. Toilets have spigots in the bowl underneath the rim that shoot water into the toilet when flushing. In addition, many toilet bowls are design to flush a certain way. This is all to prevent splashing as the toilet flushes waste away. Yep, that’s it. It is just the spigots of water that refill the toilet bowl.

Some people say ignorance is bliss. The myth supplies the toilet with a level of intrigue– a connection to the larger forces of the world. Really, it is just engineering. Sometimes the truth is boring.
