"Sure it will." Dean smiles. He takes a quarter out of his pocket and a pack of matches. "This is the part that John has to help you with. You can't play with matches, got it?" Dean smiles.

He peels off the part of the pack that you strike the match with, bends it slightly and lays it across the quarter so that the black side is face down and arched away from the coin sort of like a bridge. He lights a match and then lights the striking paper.

"Now you just wait until it burns."

Dean waits then blows off the burnt paper. "See the brownish stuff that's left on the coin? Give me your fingers."
