Allan, you're terrible

Something else impressive....drop a knockout down the back of a service panel, then fire up service. You will have a full grown thunderstorm inside the building, complete with clouds, lightening and thunder. Works best with at least 660v, don't try this at home, your results may differ, offer void in any state that would sue you.

What you did reminds me of high school and working on cars. Have someone hold your hand, then grab that spark plug wire that is popping fire to the manifold. You won't feel it, they sure will. OR, do like someone I know.......get mad at your tractor and change out the 6v coil........with the key on. If I wasn't mad before, I sure was after. Dang, those things pack a punch.
