This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

By taste.
Fun fact: A skilled linesman can use their tongue to tell the difference between 9V DC and 115kV AC.
The more you know*
You can tell it's 14.4kV by the linemans muscle spasms and sudden loss of consciousness. If he bursts into flames or is immediately vaporized, that's the 115kV.
Although, the way you can tell if the lineman really knows what he's doing is if he gets someone from the right-of-way crew to do the tongue test for him.
A great tip for those who need a little cooling off after the end of a hot day; who would have thought to include AC with power lines! What will they think of next?
well, they can, once....
