The title says it all. You borrow a coin and a cigarette, slowly but surely you push the cigarette through the coin. Just as slowly you remove the cigarette, and just as surely as you started there's hole, just a coin and cigarette which you return to their owners completely unharmed. No resetting you can do again instantly. Yes the precision made coin does almost all the work for you. Watch their jaw drop, this is real stunning magic. If they don't worship you after this, give up.
