It twitches, dances, and rises as if a restless phantom is struggling within its folds. The room fills with gasps and nervous laughter—your audience can’t believe their eyes. Is it a trick? A spirit? You decide how long to let the mystery linger before revealing the secret—or keeping it deliciously unsolved.
