Jacob’s Ladder 2007 (59" x 17" x 15")
 
It doesn’t matter if you’ve already seen one of these, they are always mesmerizing.  Step on the foot pedal and an arc of electricity climbs up the electrodes, or in this case, salad tongs.  The meter panel reads input voltage, and output to the pointless  indicator light.
Materials:
Night stand, vacuum cleaner, hurricane lamp, neon sign transformer, volt meters, baking pan, foot pedal, salad tongs.
