"Crackers" are very common at any festive events, especially at Christmas. They consist of a beautifully decorated cardboard cylinder containing a tissue party hat, a motto (British joke or riddle), a snap (popping device), and a small gift. At dinners and parties, crackers are used to decorate individual place settings and are usually opened prior to serving the meal. Crackers are usually shared between two individuals, one pulling on each end producing a small **BANG**. At Christmas, crackers can also decorate the tree or the stocking. You can also use crackers as welcoming gifts, invitations or gifts for special occasions such as Valentine's Day and Mother's Day.
History of Crackers
Christmas crackers were invented by Thomas Smith in 1846.
During a visit to Paris he came across the bob-bon, a sugar almond wrapped in tissue paper (with a twist either side of the centrally placed sweet). Thomas decided to try selling similarly wrapped sweets in the lead up to Christmas in England. His bon-bons sold well at Christmas but not at other times of the year.
In the early 1850s Thomas came up with the idea of including a motto with the sweet. As many of his bon-bons were bought by men to give to women, many of the mottos were simple love poems.
In about 1860, Thomas added the banger, two strips of chemically impregnated paper that made a loud noise on being pulled apart. At first these novelties were called 'cosaques', but they soon became known as 'crackers'.
Unfortunately for Thomas, his 'cracker' idea was copied by other manufactures and so he decided to replace the sweet with a surprise gift.
When Thomas died his two sons took over the business. The paper hat was added to the cracker the early 1900s and by the end of the 1930s the love poems had been replaced by jokes or limericks.
