When I was about 13 years old, my buddies and I were exploring the local
woods. We came to the chain link fence boundary of a hunting preserve.
It had a wire running along the top of the fence. One guy picked up a
branch and touched the wire with it. He felt a strong electric tingling.
Being 13, we all ended up trying that.

Then one guy found a metal pipe and tried touching the wire with that.
The reaction was much, much different. Nobody felt an urge to repeat
that experiment.

I thought that the classic test of a suspected electric fence was to
urinate on it. Said to result in very certain results :-)

A well known educational technique. You only do that once.

Leaning over a car in the rain holding a plug wire to check
spark is equally attention-grabbing.

In the fifteen or so years I designed and built ultra-high voltage (up to 1800V, scary stuff) thermionic tube hi-fi (with electrostatic loudspeakers up to 5500V), I gave myself only one shock, fortunately a brushing contract at mains source rather than enhanced voltage or boosted current. Once was enough to make me take care in the rest of my time prototyping high tension gear.

Sample you can build if you're skilled and careful: http://www.audio-talk.co.uk/fiultra/...trafi-crct.jpg

A chap I worked with at one period once stated that he had paid
someone to urinate on the spark plugs of a running engine. He said
that it provided a very visible indication of whether the ignition
system was operating :-)

At the time I commented that it probably gave some sort of indication
of the level of electrical knowledge in the general public :-)
