Christmas cracker
A Christmas cracker is a hollow card tube covered with brightly coloured paper twisted on each end. When pulled apart, it makes a pop sound. It usually contains a small gift, a paper crown hat and a joke. It is generally used at Christmas celebrations, usually shared by two family members to compete by tugging on each end until it breaks apart, the person who retains the tube containing the gift gets to keep the gift.  It is a British tradition which started back in the 1840s.
