The radio shows were particularly well received and quite a few people 
came forward to participate. In one we were talking about the large 
Tesla Coil we had as part of the stage set for the shadow play 29 and it 
came upon me that electricity at very high voltage was less dangerous 
because of the minute current it contained.30 I couldn't communicate 
this to Hank, because we were on air, other than to say I was about to 
commence the demonstration. "This is what happens when you touch the 
secondary of a Tesla coil as was done by Nicola Tesla in front of the 
Royal Academy at the turn of the century."

Hank was more shocked than I was about to be and his feelings were 
obviously sensed by the audience, some  of whom covered their eyes so 
they wouldn't see me die as I put my hand on top and asked him to turn 
it on. I don't remember much except a tingling sensation and I probably 
looked quite sparkly.  There was a relieved exhalation of breath from 
the direction of the audience when it was turned off that moved my tie, 
and we immediately went on to "Back, Back, Back!  To a time before 
history...," the CAVE MAN section of the show.
