And it doesn't really seem to be dependant on which tap you use. As long as the water is reasonably steady (ie: not visibly swirling anti-clockwise) it goes out clockwise. Ordinarily it swirls out clockwise from any sink or tub or bath I use. I would think it should be the same in New Zealand... Out of interest I will check it out on a airplane when I next cross the equator. It may be, as other posters have suggested, that the mechanical vibrations will prevent getting consistent results but it would be interesting if it was consistently swirling out clockwise on one side of the equator and anti-clockwise on the other. Has anyone tried it yet?
