The effect is real enough and others have repeated it elsewhere. In hindsight I'm glad I was quite specific in describing the water 'jet' in my experiments. viz/ a tightly-concentrated stream of droplets rather than a 'solid' stream of water as John seems to have isolated this as a possible 'culprit'. The Moss Effect! ... fame at last! :-) ...move over Henri Coanda!.. but he's another story ;-) With apologies to any who have found this off-topic thread tedious. Tony Moss
