To get back on topic hear - there don't seem to be any strong opinions about the "third rail" theory.

I have one.

A small stream of liquid exits a nozzle at a constant velocity. As gravity acts on the stream the liquid accelerates toward the ground per the above information regarding fatal falls from a chair.

As the liquid accelerates toward earth a given volume of liquid is "stretched" over a distance of ever increasing length. The result of this is that the steady stream quickly breaks into a stream of discrete dropletes that are not connected.

Unless the daring individual's peepee was quite close to the third rail (inches), I don't believe it would be possible to have the steady stream of liquid which would be necessary to complete the circuit between the peepee and the rail.

I vote for FALSE on this one.
