"The magician sealed him in her mystical chamber, waved her hands around and opened the box... the trick was great! Ken was gone."
—Becky, Detective Barbie: The Mystery of the Carnival Caper
A magician asks for a volunteer in the audience or uses his assistant to place him or her in a regular cabinet. He then closes the cabinet, waves his wand to tap the box, opens it to reveal that the person is gone! It is believed that there is a trap door or a hidden exit in the box to make it all an illusion.
A Running Gag in this trope is that the person either escapes or doesn't know how to get back in, leaving the magician flabbergasted and the audience booing. For a more dramatic twist, instead of the volunteer reappearing alive and well, the magician opens the box and a corpse falls out. Sometimes, a curtain will be used instead if the subject is bigger.
Since it is a Discredited Trope and easy to perform, children are usually doing this magic trick. A magician will have to really make it presentable or impossible in order to wow the audience.
