Q: If a man hangs on an un-insulated wire using both his hands what will happen and why?
Hanging off of power lines is a very effective way to get yourself killed a lot. Turns out that the voltage in power lines is high enough that it can jump a fair distance (given the chance). Electricity is a lot like water, with electrical current being a lot like water current, and voltage being a lot like water pressure. Same thing would happen if the wire snapped; you’d become part of the wire. By the way, and I can’t emphasize this enough, as safe and fun as hanging on power lines might seem, it’s both deadly and boring.
