what are xmas crackers

Christmas crackers are a traditional British festive confectionery that are typically made with a cardboard cylinder, filled with a small trinket or toy, a paper hat, and a small slip of paper that contains a joke or trivia. They are pulled apart by hand, producing a loud "crack" sound, and the contents are then revealed. Christmas crackers are a staple at many British Christmas celebrations and are often considered to be an essential part of the holiday experience.
