Designer: Guy Jarrett

Guy Jarrett described the effect in his book Jarrett Magic. A box is hung on the front of the “grill” (the bars of the jail door). The assistant stands inside the cell. A door is placed in front of the box, closing it. The magician explains it’s necessary to hide the method because otherwise criminals would escape from jails across the country. The door is removed from the outter box and the lady is shown to have penetrated the bars of the cell.
