Dove Vanish Box

The magician shows the audience a box covered by newspaper sheets. He lifts the lid, and puts a dove inside. After a magical gesture, he punches his arm right through the lid, breaking the newspaper that covers it. Not finding the dove, he then proceeds to punch through, one by one, all the pieces of newspaper that cover the sides and bottom of the box… the dove has incredibly vanished!
