Jacob's Ladder

A Jacob's Ladder is essentially a high voltage travelling arc. When high voltage is applied to the gap, an arc forms across the closest distance between the two wires at the bottom. As the heated arc and the ionized air rises, it carries the conducting current path with it. As the trail of ionization gets longer, it becomes more and more unstable, finally breaking, only to restart at the bottom.
