6. Box of Spears
In this classic trick, an assistant climbs into a cardboard box that is pierced with several spears. While the spears appear to penetrate the box, the assistant remains unharmed. The secret lies in the design of the box, which features strong rubber flaps and a protective vest worn by the assistant. These elements redirect the spears away from the assistant’s body, giving the illusion of danger without any real risk.
