If water spins clockwise when it drains in the northern hemisphere, and water spins counterclockwise when it drains in the southern hemisphere...which way does it spin at the equator?

Its not a myth at all! I don't know why you ppl are saying that. My Earth Science teacher is American but lived in Australia and he spent like an hour long lecture on the spinning toilet water. There are many factors but it has to do with the Coriolis Effect...not magnetism.

Its a bit of an urban myth that it spins different directions depending on nothern/southern hemisphere. It only affects very large swirls in oceans (Coriolis Force). In sinks in the home, differences in the style of sink, and where the tap is has a greater effect so it can spin different ways in different sinks in the same house.

On the equator, it will spin one way or the other depending on the influence of other factos like water current etc.

It spins the same direction no matter where you are. Have lived in both Northern and Southern Hemispheres.

It's a myth, I'm afraid.
The way the water spins when going down the plughole depends upon factors including the shape of your sink/bath, faucet design, water pressure etc and not on where you live in the world.

According to the Coriolis Effect...this is untrue...Water drains the same way in both hemispheres.

This MYTH was started on an Episode of the Simpson's. Water drains clockwise in both hemispheres.

Here is a website that will prove me right. I sincerely hope that everyone reads these websites...they are correct and from very reliable sources...my elemental geosystems professor at the University of Arizona in Tucson, AZ

This has nothing to do with the Coriolis effect if this is what you mean. Water spins in a sink in a certain direction because of the shape of the sink, and has nothing to do with that urban myth !

It DOES drain straight down, without swirling at all. But you have to be right on the equator line, a few meters either way and it'll swirl.

That's how they used to find the equator line, by the way.

It spins both ways depending on the week.

Your premise is wrong. It doesn't have a preferred way to spin in something as small as a sink or a bathtub

You have to poke it down the plughole with your finger.
