Christmas crackers are a fun and festive way to add excitement to any holiday gathering. To use a Christmas cracker, first, take the cracker in both hands and gently pull it apart, making sure to hold on to the ends so it doesn't explode in your face. When you pull the cracker apart, it will make a "pop" sound and release a surprise inside, such as a small toy, a paper crown, or a joke. Each cracker also contains a small piece of paper with a cheesy joke or riddle written on it, which you can share with your friends and family.
