From Other ExperimentsA tight column of spiralling material occurs during electric discharge experiment![]() To more discharge images of spiders The next image shows the result of a dark-discharge (no arc) from a laterally-stationary probe(my finger) lowered toward a plastic lid, containing sifted and strained dirt, on the monitor (powered on for this phase). I could feel strong air movement as the material was removed, note that the centers were not disturbed in either feature. The small one was made second as charge equalibrium was occurring. ![]() ![]() The additional features were made with the power off.These next images are from the pass-over monitor experiment![]() The crater-like features and the negative-spiders are two ends of the same discharge.![]() There are interior features in these crater-like circles which may give us a clue to dendritic ridge formation. |
