    You can test if a 9 volt battery is good or not by touching the 2 prongs on the end to your tongue. You’ll know if it has juice or not.

      A basic AAA battery has enough amperage to kill a human without the ohmage that the skin provides.

      One time a guy got curious and poked himself with copper wires so they would be in direct contact with his electrolyte-filled blood. Those wires were attached to a 1.5v battery, and he electrocuted himself and died.

      You can do the same with any two wires to test if they’re live.
      Depending on the voltage, either you’ll know, or the people around you will.
