When I run my "big" [18" sparks, but only 35 microamps short-circuit
current] VDG everything within several feet stars to show visible
discharge. If they sharp points are close there isn't much voltage
rise. If I approach it with my hand I'm liable to get zapped, but if I
hold a pin in my hand [pointed toward the terminal, of course] and
approach nothing much happens. Same phenomenon.
"St. Elmo's fire" is another manifestation of the same sort of thing.
