Dave is correct. The Coriolis force is proportional to the radius of the rotation of the system in question so it manifests itself in the movements of huge systems (like the North Atlantic gyre or the movements of entire weather systems) but is several orders of magnitude too weak to be detectable in movements of pots or (as the popular conception has it) in the swirling of water in toilet bowls or sinks. ;-> The Wikipedia has a rather good (although somewhat technical) entry on the Coriolis Force at: http://en.wikipedia.org/wiki/Coriolis_effect Cheers, Chris _._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._. _.
