Necessary equipment. One cup of water, one piece of tissue paper (toilet paper, etc), one dime, cigarettes for the contestants.
To start, wet the tissue and place it over the cup. (I don't remember whether you wet the whole thing, or just the edges.) In the middle place a dime. 2 players then start taking turns. In each turn you must burn one (and only one) hole in the tissue with your cigarette. The person whose hole causes the dime to fall in, loses.
Cheers,
Ben
