* Illusions: The most common theory is that he uses a hidden compartment or a duplicate body to make it appear as though he's vanished. This could be achieved with clever staging, mirrors, and possibly even smoke and mirrors.
* Distraction: The act often involves a lot of movement, flashing lights, and loud noises, all designed to distract the audience's attention and make it difficult to follow what's happening.
* Misdirection: Magic often relies on leading the audience's attention away from the key moment of the trick, making them focus on something else.
It's important to remember: Criss Angel's "dematerialization" is a performance, not a real-life event. It's a carefully crafted illusion intended to amaze and entertain the audience, not to be taken literally.
