I have a fairly small coil driven from a 15KV 60Ma Neon Xformer that
throws around 30" sparks. I have tried hanging on to the end of a Flouro
tube and drawing a few sparks with that but even though my coil runs at
over 300Khz, it was fairly unconfortable, i.e. I got a pretty strong
tingle down my arm.
I am also intigued by how these guys draw off huge arcs using larger
coils that run a lower freqs. Maybe they use hidden earth wires.
