Those large masses of air and moisture are subject to the Coriolis effect, which is a proven factor. Water in sinks is far too tiny a mass for Coriolis to have any effect whatsoever. Hence the controversy.

Large long range ballistic artillery shells are subject to Coriolis.

That is what I think Hugh in company with others, but nevertheless it is still inconclusive.

They say it takes 24 hours for a full sink to settle before you pull the plug. But even pulling the plug can determine which direction the vortex takes. It only takes a tiny disturbance to dictate which way the vortex spins.
