Christmas crackers are a fun and festive tradition in many parts of the world. To open a Christmas cracker, simply hold it at both ends and pull. As you pull, the cracker will make a loud popping sound, signaling that it has been opened. Inside, you will find a small gift, such as a toy or a piece of jewelry, along with a paper crown and a joke or riddle. It's a great way to bring some holiday cheer to your celebrations!
