Convex pimples make dark spots in the light reflected from the water surface to a screen, while concave depressions make bright spots. It was definitely a bright spot, a depression in the water. But note well that this only occurred with an abnormal "thread." The usual "threads" make 5mm holes in the mist, while the one which made the surface-dimple was also creating a large region of obvious turbulence many tens of mm across. The more common threads are too weak to create easily detected surface deflections. > > 2/ Have you observed those airstreams on a solid collector? A friend has seen "spiderwebs" extending into the space around an oil-wetted surface of an x-ray DC power supply. The "spiderwebs" had to be back-lit in a darkened warehouse. It is possible that all these phenomena are created by Electrospray, where a droplet clinging to a charged surface begins emitting a series of microscopic charged droplets. An older form of ink-jet printer was based on this type of electrostatic droplet-series emission. (((((((((((((((((( ( ( ( ( (O) ) ) ) ) ))))))))))))))))))) William J.
