How to do human levitation magic

Magicians don't reveal magic secrets. But I know a few. But I can only reveal one, I only know these few tricks, completely revealed, friends see it, how can I show friends ah!

Practice: put a rope with a knot at both ends. Then put it to the back of the neck, with two big fingers through to the center, counting one, two, three, the two hands of the big fingers slowly close, and then counted to three, the left hand of the big fingers released, with the index finger of the left hand to hook the right hand of the rope, and then pull out is it, to be fast, quick eyes, quick hands. I have been practicing for more than a month before others can't see it. This is the illusion of others!
