What is the most famous magic trick of all time?

The most famous magic trick of all time is likely Houdini's 'Metamorphosis.' This classic illusion involves Houdini being handcuffed and locked inside a trunk, which is then locked inside a cabinet. His assistant stands on top of the cabinet, drops a curtain, and then in a matter of seconds, the assistant steps down from the cabinet and Houdini is standing on top of it. The curtain is dropped again, and when it is lifted, Houdini is back inside the trunk and the assistant is back on top of the cabinet.

This trick is not only impressive due to its complexity and speed, but it also has a sense of danger and drama that has captivated audiences for over a century. Houdini himself performed the trick numerous times throughout his career, and it has since been adapted and performed by many other magicians around the world.
