oz for the water swirling down the plug'ole to be done to prove the point successfully, you would have to set up two tanks, each holding a minimum of 10 litres of water, with a single hole with a spigot in the centre of the bottom, one each side of the equator at a minimum of 1 kilometre distance from the equator, and allowed to stand to settle for a minimum of 24 hours, to ensure there were no little swirls or movement in the water of any kind. Then you will get a true reaction when the spigot is opened. The reason being that any disturbance could upset the natural flow of the water to the extent that it could be influenced to flow the 'wrong' way. Just thought I'd let you know. ;o}
