# Frequent question: Does the toilet flush in the opposite direction in Australia?

Contents

Australian Toilets Don’t Flush Backwards Because of the Coriolis Effect. … The real cause of “backwards”-flushing toilets is just that the water jets point in the opposite direction.

## Do toilets flush the other way in the Southern Hemisphere?

Can you actually use a flushing toilet to figure out whether you are in the Northern or in the Southern Hemisphere? Sadly, you cannot, because toilets tend to angle the jets that pass water into the bowl to drive the direction of draining water.

## Why does the toilet flush counterclockwise in Australia?

Because of the rotation of the Earth, the Coriolis effect means that hurricanes and other giant storm systems swirl counter-clockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere. In theory, the draining water in a toilet bowl (or a bathtub, or any vessel) should do the same.

## Does water swirl the opposite way in Australia?

For any normal bathtub you are likely to encounter in the home, however, the answer is no. “The tendency of a circulation in a fluid to develop in a clockwise direction in the Northern Hemisphere and a counterclockwise direction in the Southern Hemisphere can be traced to the earth’s rotation.

## Does water go anti clockwise in Australia?

Objects not attached to the surface of the earth (water in a sink going down a drain) will create a vortex going the opposite direction. So in the Northern hemisphere, it moves clockwise. In the Southern hemisphere, it moves counter clockwise. On the equator, water goes straight down.

## Why Coriolis force is zero at Equator?

Because there is no turning of the surface of the Earth (sense of rotation) underneath a horizontally and freely moving object at the equator, there is no curving of the object’s path as measured relative to Earth’s surface. The object’s path is straight, that is, there is no Coriolis effect.

## Why is Coriolis effect different in Southern Hemisphere?

Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. … But because the Earth rotates, circulating air is deflected.

## What direction do toilets flush in Australia?

Australian Toilets Don’t Flush Backwards Because of the Coriolis Effect. File under “News to Me”: you know that old story about how northern hemisphere toilets flush counter-clockwise, and southern hemisphere toilets (and buckets, drains, and such) flush clockwise, due to the Coriolis effect? It’s bogus!

## Why do toilets flush backwards?

The Coriolis effect is probably the most scientific excuse humans have for staring into toilet bowls. The effect makes objects on the Earth curve when they should go straight, and it’s why some people insist that toilet bowls flush in the opposite direction on the southern hemisphere than in the northern hemisphere.

## Do all hurricanes go counterclockwise?

Do All Hurricanes Rotate in the Same Direction? … All hurricanes in the northern hemisphere rotate counterclockwise, while hurricanes in the southern hemisphere rotate clockwise. To be technical, hurricanes in the southern hemisphere are not called hurricanes, they are called cyclones.

## Which region of the globe actually moves faster?

The top (and bottom) of the earth travel slowest, while the earth rotates fastest in the center.

## Does the Coriolis effect affect bullets?

The Coriolis phenomenon affects the flight of a bullet in the Northern Hemisphere so that when firing north or south, the bullet sways to the right and in the Southern Hemisphere to the left. The more your firing line is in the east-west direction, the less the effect of the Coriolis.

## Does the rotation of the Earth affect baseball games?

However, they can’t seem to agree on the role that rotation plays in the way toilets flush and baseballs travel. … Basically, the Coriolis effect refers to the way that the Earth’s eastward rotation influences how we see the direction of travel of certain moving objects.

## What happens when a hurricane crosses the equator?

If a storm did cross the equator though, what would it do? Nothing at first, but as it moved further into the opposite hemisphere, Coriolis would be working against the storm and it would spin down, become disorganized and cease to be a hurricane, probably becoming a remnant low.

## Why do hurricanes spin counterclockwise?

Particles traveling from the equator to the south experience a similar curve in the opposite direction. … This creates a circular spinning pattern as air travels from areas of high pressure to low pressure. That’s why hurricanes originating in the northern hemisphere rotate counterclockwise.

## Why does water circle the drain?

Before opening the drain, the water already has some motion, although it might be too slow for you to notice. As the water moves toward the drain, its rotational motion gets amplified, i.e., it starts swirling faster (see Figure 1).
