The Illusion:
* A performer stands with their head resting on a platform, seemingly held by only a thin rope.
* The platform is then "lifted" up, leaving the head seemingly suspended in the air.
The Secret:
1. The Platform: The platform is not a solid object but a thin metal ring or frame.
2. The Rope: The rope is actually attached to a hidden support structure under the table or the performer's clothing.
3. The Head: The performer uses a clever technique to keep their head stable. They lean slightly back, and a hidden support, often a collar or neck brace, keeps their head upright.
How it Works:
* When the "rope" is pulled, it actually pulls on the hidden support. This pulls the platform upwards, creating the illusion of the head being lifted.
* The performer's head appears to remain stationary because of the hidden support.
Important Note: This trick requires a great deal of skill and practice to execute convincingly. The performer must maintain their posture perfectly and avoid any sudden movements that would reveal the secret.
The "beheading" effect is simply an exaggeration of the illusion, adding a comedic element to the trick. Daniel Radcliffe's performance on QI highlights the absurdity and the cleverness of this classic magic trick.
