Growing up in Australia, we always had Christmas crackers on our plate when we sat down to Christmas dinner -- cardboard tubes covered with crepe paper that you pulled (with the help of the person sitting next to you) until they broke open with a "crack" noise. Inside was a tissue paper hat which was then worn throughout the meal to add a silly air to the festivities.
Well, when I saw this idea, I had to make my own crackers, complete with an assortment of materials so that we, and our six guests, can each make our own hat tomorrow.
I'll post photos of the results. Only one more sleep!
