EM3.1 Electric Spark (Jacob's Ladder)
This is two metal poles that are next to each other, narrow at the bottom and farther apart at the top. (See picture) A spark appears at the base, travels up the length of the rods, and then dissipates. When it dissipates, another spark begins at the bottom. The spark is generated by a spark coil on the same shelf. The better the initial spark into the coil via the switch, the better the results. Performance varies with humidity.
