APPARATUS
Jacob's ladder 202-13-F

DESCRIPTION
This consists of a step-up transformer connected to a set of rabbit-ear electrodes.  The voltage is sufficient to ionize the air between the electrodes at the bottom where the gap between them is small.  The arcing heats the air and the hot air/plasma rises between the electrodes.  When the distance between the electrodes becomes too great, a new spark occurs at the bottom and the process repeats.

NOTES

This produces lethal voltages.

Place plexiglas cylinder over electrodes.

This can be set up in the display case.
