The 'Cave of Magic' card trick is a timeless illusion that highlights a key principle in magic. If you haven’t experienced it yet (or similar versions), give it a try and observe how it unfolds. It’s truly astonishing on the first attempt, especially if you don’t spot the trick right away. Make sure to attempt the trick yourself before reading any explanations.
Similar to numerous magic tricks, this one depends on suggestion and the human brain's tendency to overlook minor details. To understand the trick better, repeat it while selecting two or three cards instead of one. Try it again, jotting down the cards from the initial deck and comparing them to the final deck. You’ll notice that every card has been altered!
Most people, when attempting this trick, perceive the first deck as simply 'a group of cards.' The brain doesn’t retain the specific details of each card. When the second deck is revealed, the brain again interprets it as 'a group of cards.' The fact that all the cards are different goes unnoticed because the brain assumes they are the same, having not stored the finer details.
This same principle enables a magician to perform the 'sawing a person in half' illusion. When the assistant is placed in the box, her head and feet are visible at either end. As the magician rotates the box, the assistant pulls her real feet back and substitutes them with fake ones while the audience’s view is obscured. Being a contortionist, she tucks her legs into the upper part of the box, allowing the magician to 'saw her in half.' Since we initially saw her feet through the holes, we assume they remain there throughout, making the illusion utterly perplexing!
