It will spin either way.

The twisting effect of the Coriolis force is real and does influence certain large things like the movement of air masses, but the effect is so small that it plays no role in determining the direction in which water rotates as it exits from a draining sink or toilet. The Coriolis effect produces a measurable effect over huge distances and long periods of time, neither of which applies to your bathroom. Toilets and sinks drain in the directions they do because of the way water is directed into them or pulled from them. If water enters in a swirling motion (as it does when a toilet is flushed, for example), the water will exit in that same swirling pattern; as well, most basins have irregular surfaces and are not perfectly level, factors which influence the direction in which water spirals down their drains. The configuration of taps and drains is responsible for the direction of spin given to water draining from sinks and bathtubs to a degree that overwhelms the slight influence of the Coriolis force.

It is anticlock wise in norther hemisphere and clock wise in southern hemisphere of the earth (Corialis effect). This due to sphere shape of the earth. The angular velocity of any point in the earth is same at any time. But the linear velocity of different points in the earth at different latitudes are different. Suppose, consider two points in the northern hemisphere, one near the north pole and another near the equator. The angular velocity for both the points are same. But the linear velocity of the point near the equator is greater than that of point near the north pole. As the earth rotates from west to east, the point near the equator passes longer distance than the distance by the point near the north pole from west to east. Now come to the point. When the water escapes from the drain hole of a tank or container, the water comes under the control of earth's gravitation. This force is transferred to the water existing the tank or container giving anticlockwise spin. If the same phenomenon occurs in the southern hemisphere, it is clockwise. eg. the cyclones spin in anticlockwise in norther hemisphere and the reverse is true in the southern hemisphere.

As Mike A says, it truly is the CORIOLIS result. The Earth's rotation looks to pull falling products to the right contained in the northern hemisphere and to the left contained in the southern hemisphere, therefore draining water swirls clockwise contained in the north and anti-clockwise contained in the south. on the equator, water falls instantly down. Gravity does not reason the swirling.

It spins counter-clock wise. Its because of lower pressure caused by the water rushing out at the bottom of the bowl. Its alot like low pressure systems spinning counter-clock wise in the earth's weather.

Depends what hemisphere you're in. As in, on Earth. North and South produce different directions.

In the western hemisphere it's clockwise in Australia it's counter clockwise

it goes anti clock wise

i used to think that it depends on the Earth hemisphere - until i tried it and found out that you can get both clockwise and counterclockwise whirl in the very same tub!

Depends on where you are. Remember when the Simpsons went to Australia.
