5M20.3 Jacob's Ladder

[Setup Time: 10 Min.] [Current Condition: Good]

Info

A very long set of two parallel wires is held vertically. The wires are connected to a neon sign transformer that is connected to a varaic. At high enough voltage an arc will jump between the wires, and the arc will rise up the tube as the air heated by ionization rises.
