In this experiment, around 18,000 volts are applied near an apple, and the electricity jumps through the air instead of touching the wire directly. Air normally acts as an insulator, but at very high voltages, the electric field becomes strong enough to break down air molecules, turning air into a conductive path. This phenomenon is called electrical arcing. Once the arc forms, current rushes into t
