Take an old Lamp Cord and, seperate the wires by about 12", then strip 1/2" of the insulation off each end.
Using some CA, glue one end of the bare wire between the Thumb and Forfinger of each Hand.
With the help of a 3rd Hand, plug this into an electrical outlet. If you get Shocked, then the CA should work for the Battery Packs too.
***NOTE: This is ONLY a Joke. DO NOT try this at home !****
