There are several "tricks" in Jerome Murat's incredible and beautiful piece. At the beginning, his right hand is inside the second head and there is a fake arm/hand attached to the staff he seems to be holding. At the point when he begins shoving the head out of his way (to see more clearly) he cleverly removes his hand from the second head, removes the fake hand from the staff, and takes the staff with his real hand. He releases the staff very soon thereafter and it appears as if he has been holding the staff the entire time. (At this point he is manipulating the second head from the outside, with both hands.) When he opens the lid to the box he slyly attaches a pole to the head, which he uses to show the head trying to fly away; it extends how far he can push the head away. Next, when he brings the head close again, he removes the pole and attaches invisible string/wire from the ceiling to the head, wires controlled by someone in the rafters. Then the lightning strikes and the lights go out, and he begins to "remove" his own head. At the same he pulls the headpiece from his own head he pulls a black stocking over his head/face and it appears that he has removed his own head (since the stocking is the only thing not glowing in the black light). The person in the rafters floats the second head (which is also a mask) over to him and he pulls it over his stocking-covered head, so it seems as if the second head has replaced his original head. I hope that explains it well enough for you. It's an absolutely brilliant work of art, a combination of mime, magic, and poetic art and symbolism. The beauty of the piece is not diminished at all by knowing how he acheived it. Bravo, Jerome Murat, Bravo!
