So this video is an illusion of a woman being impaled on a sword by a magician. The sword is sticking straight up in the air and the woman is wearing a black bikini (but notice the back brace on it). The magician lifts her up and places here on top of the sword. He then spins her around and it looks like she is drilling down on the sword (and faking being dead). Finally he lifts her off the sword and she is fine again. As far as I can tell she has a steel back brace built into the biniki which is supporting her on the sword. When the guy spins her around the sword on the bottom screws down into the base and the woman releases a sword from the front of the bikini. When the magician guy takes the woman off the sword he lifts her up and his hand at the top of the sword telescopes it back into the bikini.
