SUMMARY
The direction of water swirl in sinks is influenced primarily by initial conditions rather than the Earth's rotation. While the Coriolis effect theoretically affects fluid dynamics, its impact is negligible in small-scale environments like sinks. Disturbances such as pre-existing water rotation play a significant role in determining the swirl direction. Popular science channels like Veritasium and Smarter Every Day have explored this phenomenon, emphasizing the importance of initial water movement over geographical hemisphere effects.
