How to make a Jacob's Ladder -  You will need 12K-15K volts AC (50/60) Hz at say 20-30 mA. A neon sign (luminous tube) transformer is the usual source though an oil burner ignition transformer will work in a pinch (some say better and cheaper) or you could build an inverter type power supply.....(Circuit design added 11/06)
Jacobs Ladder -  People have long been fascinated by electric arcs--and perhaps put off by them.  They show up as lightning, Tesla coil discharges, and long sparks that sting as you reach for the doorknob on a cold, dry, winter day. This Jacob's Ladder project turns electric arcs into a dramatic but harmless conversation piece..... [Tony van Roon's circuit]
Jacob's Ladders (mistertippy) -  A Jacob's Ladder does not serve any real purpose other than that it shows the properties of an electric arc, or as a visual display. It is composed of two vertical rails that are close to one another at the bottom and gradually spread out, forming a "V" shaped structure. A sufficient voltage to breakdown the air gap at the base of the "V" is applied to the two rails. As the ionized air is heated, the arc begins to rise with the more conductive hot air.....(electronic Circuit diagram added 03/03/03)
