Karl,
Thanks for posting the YouTube film. It's great to see some of your work.
Jetijs and Inquorate,
As for why Karl was not electrocuted, there are a number of reasons. First, he's immortal! Second, he knows that Tesla discovered that the body presents a circuit of this type more of a capacitor than a resistor, so the energy just flows through. Electrocution is only a problem when your body presents the opportunity for a significant "voltage drop" to the system. But, in this system, already in a "short circuit" condition, the body presents a very high impedance so no energy can be "dissipated" in the body.
But like Karl says, don't try this with ordinary electric power.
Inquorate,
TWO Solipsists! Very funny!
