A new and different production trick, with a fresh touch of magic. The performer reaches into his empty hat and says he will produce a rabbit. But he produces only a handkerchief, which, when opened, reveals an image of a duck—not a rabbit.

Surprised, the performer shakes the handkerchief, and the image of the duck has turned into a rabbit! The change is magical—you simply shake the handkerchief and it changes to show the rabbit, even though your audience realizes it’s the same picture, just flipped!
