There's all kinds of fun you can have playing with an electric
arc. The concept is simple: Turn on NST, draw a continuous arc between
opposite poles, have fun with the arc. On my 12000/30 (360VA) neon
transformer, the arc is hot enough to disintegrate aluminum, melt
steel, and get about half a CC of granite to glow shades of red,
orange, and white. Pictures as soon as I take them.
