Vanishing bird cage
The vanishing bird cage, also known as the flying birdcage, is a classic parlour magic effect that was invented by French magician Buatier De Kolta. The trick has also been used by magicians Carl Hertz, Harry Beardmore, Harry Blackstone (Sr. and Jr.) John Mulholland, John Angel, Sabrina Vera, and Tommy Wonder. The magician displays a bird cage, holding it between both of his hands. The cage is rectangular, about six inches tall by six inches wide by eight inches long, and made of wire on all six sides. Often there is a bird, though in modern performances of the act it is usually fake, inside the cage. The magician will offer the cage for inspection by an audience member, but he will never actually release his grip of it. Then, without covering the cage, the magician makes a sudden motion and the cage (and anything inside) vanishes from sight. A variation of the trick was featured in the 2006 film The Prestige. Method The bird cage is designed to collapse if it is not supported from both ends. Two of the opposite corners of the cage pull away from each other so that the box becomes somewhat of a tube,
