dd - no the water still spirals down into the plughole - only it does not always turn to the right as in the northern hemisphere or to the left as in the southern hemisphere - it will go either way depending on the initial movement of the bathwater relative to the orifice. In a truly random universe 50% of your baths will end with clockwise vortex and 50% with an anti-clockwise vortex down your plughole at the equator. Even in the northern hemisphere you can get a clockwise vortex if you give the bathwater the necessary stimulus by stirring it in the right direction to get it started. Isn't this a gloriously pointless thread?
