Morning Tig. I hope you didn't pay to see that phenomenon in Africa. The Coriollis Effect as it is named is a 'global' effect not a local effect, it requires enormous physical forces such as the spinning of the earth and other geotechnical inputs. It also requires time to become established, for example the direction of cyclones and anticyclones in the N or S hemisphere.
Believe me, it doesn't happen in a bucket or bowl and it will never happen just 3 feet apart!
Quote from Scientific American:
"..."There is an African country near the equator where entrepreneurs have set up two toilets, one just north of the equator, the other just south of it. For a fee, they will allegedly demonstrate that the toilets flush in opposite directions. It is only for show, however; there is no real effect. Yes, there is such a thing as the Coriolis effect, but it is not enough to dominate the flushing of a toilet--and the effect is weakest at the equator.
"The telling comparison is between the magnitude of the Coriolis effect and the initial amount of angular momentum in the water--that is, how much is it spinning anyway, regardless of the earth's rotation. Coriolis acceleration at mid-latitudes is about one ten-millionth the acceleration of gravity. Because it is a very small acceleration, it needs a very long distance for it to produce an appreciable curvature--and hence directionality--to the motion. A toilet or sink is just not large enough. The Coriolis effect influences because wind velocities may be hundreds of times greater than the motions in a sink and because the distances involved are far larger than the tiny draining diameter in a sink or toilet...."
