Imagine holding a small tin that reveals an intriguing collection: a prediction, a long pin, and a blank business card. You captivate your audience by illustrating a voodoo doll, asking a spectator to mark a point of pain with a subtle X. The left arm becomes the target as the spectator drives the pin through the chosen spot, creating an illusion of a mystical injury. The twist? The prediction shows a single red dot, deepening the mystery. When the spectator flips the card, they find the voodoo doll perfectly pierced through that very red dot. This entire setup invites scrutiny, leaving your audience in awe and eager for more.
