Over here in Michigan, Consumers Power Co. has a really nice electrical
safety demo that they do.
They use a pole pig hooked up backwards with a big line cap to limit the
current through it.
Standard demos include setting dry wood on fire (showing it's not much
of an insulator at those voltages), and showing how an arc can reach
through a pinhole in linesman's gloves and cook a hotdog into a cinder
in a few seconds, etc.
They also show a really good non-hokey video showing a whole
subdivision where all the houses are catching on fire and spitting
