This is the box of eight Christmas crackers that each pop open to reveal one of eight plastic whistles tuned to individual notes for playing along to a traditional holiday song as an ensemble. Renowned as an English Christmas tradition since their invention in 1847, each cracker makes a safe, festive “pop” when pulled apart at either end by two celebrants, revealing one of the whistles, including other traditional items such as a paper hat, joke, and trivia question. Each whistle comes with a numbered card that corresponds to a numbered, sequenced part to be “tooted” along with one of 21 Christmas carols, including favorites such as Jingle Bells, Good King Wenceslas, and Deck The Halls. Includes a plastic baton for directing the impromptu octet to reverent music-making or to cacophonic, delightful chaos. Boxed set 13 1/2" L x 10" W x 1 3/4" H. (12 oz.)
