Why does water spin in different directions at different parts of the world?

Click For Summary
Water spins in different directions in the Northern and Southern Hemispheres due to the Coriolis effect, which is a result of the Earth's rotation and spherical shape. This phenomenon is often misinterpreted in everyday situations like water draining, as it does not consistently dictate the direction of water flow in sinks or toilets. Instead, the Coriolis effect is more prominently observed in large-scale weather patterns, such as hurricanes. At the equator, the Coriolis effect is negligible, meaning water does not spin in a particular direction.

Why does water spin in different directions at different parts of the world?

Also, which way does it spin on the equator?

If you are talking about the idea that water going down a drain in the Northern Hemisphere spins one direction and water the the Southern Hemisphere in the Other, It doesn't.

The Idea come from the fact that hurricanes follow this pattern. The reason for this behavior is The Coroilis effect.

The Coroilis effect is caused by the fact that the Earth is spinning and shaped like a sphere.

Oh, but in X-Files it does
 
I built a device designed to brake angular velocity which seems to work based on below, i used a flexible shaft that could bow up and down so i could visually see what was happening for the prototypes. If you spin two wheels in opposite directions each with a magnitude of angular momentum L on a rigid shaft (equal magnitude opposite directions), then rotate the shaft at 90 degrees to the momentum vectors at constant angular velocity omega, then the resulting torques oppose each other...
