Tesla demonstrating the effects of high frequency and high voltage electricity

In this experiment the operator's body is charged to a great pressure by a direct connection with an oscillator — The photograph shows a sheet of tin of determined size, held in hand — The operator is on the top of a stationary electrical wave, and the bar and sheet are both illuminated by the violently agitated air surrounding them — One of the vacuum tubes glows brightly, being affected by the vibrations transmitted to it from the operator's body.
