I believe that this is the link! Holy Moly! That arc is racing by! Now we know what a Jacobs ladder looks like when there are several hundred amps behind it!!!

: Sorry, I posted the wrong link. I am trying to find the correct one to the

: I think you told me about this one some time back. See above link. A

: Anyhow, I will try and find the link to the parade arc/jacobs ladder.
: Sorry for the confusion!
: Thanks! The above link is really scary - I just think if one of those

: I have also seen the parade clip, but I lost the link. If I recall, it was
: either a Mylar balloon or maybe a blast from a confetti gun (with Mylar
: strips) that was accidentally aimed towards the lines. The event triggered
: the phase-phase flashover and magnetic forces took over. If not
: interrupted, an arc will race along a pair of conductors, heading in a
: direction away from the source of power due to Lorentz forces. Sort of
: like a plasma rail gun...
: This effect has also been seen on occasion on electric railways if an arc
: occurs between the third rail and main rails. Scares the heck outta' the
