tongue shock

Our friend Aulvie showed us how to trace wires in your house using a battery.  I was tracing alarm wires in our house and this worked pretty well.  On one end of the wire, have someone hold a 9-volt battery on the red and green wires.  Then, just touch all the other mystery ends to your tongue until you feel electricity.  Saves you a lot of time.
