Hi all

Just to support John Freau assertion I extract some frames from a video, as you
know video is to slow to capture spark growing on one bang: on video you have
15.4 millisecond capture 1.3 millisecond black or 60 frames by second with a
pause of .0013 second between each frames. On tesla coil if you studied one
bang
you find: The bang duration is in the order of .2 millisecond depending of the
frequency, coupling and quenching check that paper from Terry
 http://hot-streamer-dot-com/TeslaCoils/MyPapers/modact/modact.html
and for the video capture
