	You first need about 15,000 volts AC. More if you can get it but this
is the easiest to find. I used a spark lighter from an old furnace. 60 Hz works
very well. The element may be made from somthing as simple as a straightened
coat hanger. Use some good insulators on the bottom. Space them a good two
inches appart. The bottom of the elements must be farther appart than the
bottom of the V which is about 1/4 inch appart, depending on your voltage.
The V should split appart about 1 inch for every 6 to 8 inches.

	If the spark does not ignite the elements are too far appart If it does
ignite but doesn't go up widen the gap at the bottom of the V.

	The angle of the V and the heat of the spark will determin how fast the
spart rises. Humidity and voltage will determin how high it goes.

	Please be careful with these things. Not only is the voltage dangerous,
The spark will set things on fire quickly. It also kicks out large ammounts of
ozone, concentrations of which is corrosive.

	HAVE FUN. I did
