The cracker is pulled by two people, and, much in the manner of a wishbone, the cracker splits unevenly. The split is accompanied by a small bang (produced by the effect of friction on a chemically impregnated card strip). The person with the larger portion of cracker empties the contents from the tube and keeps them. Typically these contents are a colored paper hat, a small toy, and a motto, joke or trivia on a scrap of paper. Crackers are often pulled after Christmas dinner or at parties.
