Do you ever wonder why the water in your sink forms a whirlpool when it goes down the drain? This phenomenon, known as the vortex, is quite fascinating.

Contrary to popular belief, the rotation is not due to the Earth’s rotation. Understanding the science behind this swirling vortex can help demystify this everyday occurrence.
