Just what I used to do about forty years ago.
There was a 25 kW medium wave transmitter the
antenna being guyed with eight wires attached to
four concreted beds on the ground. Each wire had a
few insulators between the antenna and the beds.
The last insulator was located near the concrete
bed. I used to climb on one of the concrete stands
and short circuit this last insulator with a thin
copper wire. A stable arc with length about 5 mm
was produced (frequency was 1242 kHz), the copper
melted slowly and the sound from the arc was the
AM program they were sending. If I accidentally
touched the guy wire above the insulator, I got a
small but painfull burn on my skin.
Despite those foolhardy experiments I managed to
survive and later became an engineer in
electronics. When I've told this story about a
radio consisting only a piece of copper wire to my
colleagues, they have not been able to believe a
word of it. Perhaps I should use this video and
try to teach them something about electricity.
