Decipher the magic screen through David Copperfield's Great Wall

In fact, David took advantage of the light to fool the follower's eyesight in this performance.

The key to this performance is the ultra-powerful rear projection lamp that shines directly onto the white curtain to reveal David's shadow. But actually due to the angle of the lamp, the light only brightens part of the curtain.

In the audience's view, David entered the iron frame covered by the curtain. In fact, there was another person who looked like David had been waiting there. While David pretended to go on stage and quickly retreated to a corner without lights, the viewers believed that the magician was going through the real wall when David quickly fell into a secret room below. That is the small staircase that is close to this iron frame.

David also took advantage of the dark corner that was not illuminated and dropped to the bottom.

Then, right in front of the audience, this real staircase containing David would be moved to the other side of the castle wall openly.

On the other side of the wall, David's two partners will perform a small performance to increase the drama before David appears. Thanks to the light effect, they used their own hands to mistaken the viewer to think that David was trying to rush out of the wall.

When the white curtains were set up, David would actually come from the secret room below to step on the dark side without the light coming and make the movements as if he had just come out of the wall.

The white curtain was pulled down and David Copperfield appeared in front of the public on the other side of the wall.

To increase the authenticity of this magic show, during the show David also attached a small chip on his body so that people could follow on the radio screen, the chip emitted a signal across the wall. .
