Magician shows an empty box to the audience and asks someone to examine the box. The question is: "Make sure there are no trap doors, mirrors, decks of cards, or mirrors..." The magician then causes the box to fall open revealing the only thing inside is... a bunny rabbit, mirrors, and decks of cards all inside a trap door.
The box folds up completely flat for storage and comes with a cloth bag to keep it safe. It also makes for a great box to hold your other props throughout your show. Examinable Box has been Blake's GO TO piece for years and now it can be yours. This is Examinable Box.
