What you want to know about is called a "Tesla Coil"
It is a simple high voltage, high frequency (well....low rf anyway)
arc generator, sort of a fore-runner to the early arc transmitters.
A simple unit I built a few years ago generated approx 180 KV and was
30x30x45 cm and operated off 6V dc using an induction coil.
I would suggest you find a book on Nikola Tesla.
The other device is known as "jacobs ladder" which when used with a
high voltage source such as a tesla coil, is rather fun to play with...
It is just two thick upright wires shaped as: \ /
\ /
The arc starts at the inside curve of the \ /
ladder and rises to the top to eventually / \
"blow-out" when the arc distance cannot be ==|==|= mounting base
maintained.
There are a few other tricks that you can do with a good low power coil...
like holding a flouro light near it, or plasma displays (try an old globe)etc.
Hope this is of interest.
