You tell a person that you will clasp his hands together in such a manner, that he shall not be able to leave the room without unclasping them, although you will not confine his feet, or bend his body, or in any way oppose his exit.
The trick is performed by clasping the party’s hands round the pillar of a large circular table or other bulky article of furniture, too large for him to drag through the doorway.
