Many, many years ago I worked with an old electrician that would occasionally test circuits in a breaker panel to determine if the circuit was hot. He would do this by sticking one hand in his back pocket and then drying his finger tips on the other hand by wiping his shirt. He would then delicately touch the hot and neutral bars with his index and middle fingers. If the circuit was hot he would get a mild tingle from the path down one finger and up the other. (Don't try this at home, kids.) Dry skin is a very good insulator. [emphasis added]
