why is it that water when flushed in australia goes in the opposite direction?

Answer 1

The Coriolis effect isn't a myth as previously stated and it has absolutely nothing to do with magnetic fields. In the absence of other, stronger forces, the rotation of the Earth causes a tendency of object to rotate in a specific direction. Counter-clockwise in the Northern Hemisphere and clockwise in the southern Hemisphere.

The force is a constant and relatively weak force but influences the direction of rotation of natural phenomena, such as storms and hurricanes.

However when it comes to toilets the turbulence and direction of the water release from the tank are much greater forces. So if you survey all the bathrooms in your neighborhood you should see mixed results.

Answer 2

What Brian K was attempting to say is that the Coriolis forces are much too weak to affect a body of water as small as a sink or toilet. The fact of the matter is that toilet water does not swirl in the opposite direction in the southern hemisphere. It is, in fact, entirely random in both hemispheres and will have much more to do with the design of your toilet or the currents set into motion by the splashdown of your turd.

Answer 3

The magnetic field pulls in the opposite direction south of the equator.

Answer 4

The opposite pull of the earth's magnetic field. It would also be that way if there were toilets in Antarctica and South Africa.

Answer 5

Because of the earths magmatic field. Northern part is one direction and the southern part in the opposite direction,

Answer 6

Because of something known as the Coriolis Acceleration, inherent to the part of the world, north or south, that your are.

Answer 7

It has to do with magnetic field. In the North it rotates anti-clockwise, in the South clockwise. Surprisingly, though, at the equater: its clockwise, but slowly (I presume)! The law of the nature!

Answer 8

Because it's down under :P

Answer 9

It doesn't. That's a myth.

Answer 10

cuz theyre upside-down.
