Re: Sparkles in the arcs

Hey everyone,
What I photographed is a bit more than your everyday average "sparkles in
the arcs", but I doubt it would work with a full sized TC.
Check out the link below. You can decide for yourselves what is happening
here...

On the left is a screwdriver which conveys about 10kV 2-3mA -at- 20KHz into the
heart of the flame. Right: a ground wire held approx. 1cm from edge of
flame. Center: ???!!!
Plasmoid maybe?
Safe coiling,
