Is the levitaton a trick supported by any scientific technology or truly a proficiency gained by trial?
I wonder about the levitation when I saw in the Utube, and some other magicl scenes that they travel from one building to another just like that and curious to know wheather any tricks in it or it is just a practice of levitating whole body in the air for hours to move up and cross over the building? if anyone got idea pls tell me.
Yes, you can levitate. You only need to place a mass similar to Earth close enough so that you are in the middle of both centers of gravity, and, voila, you have zero gravity.
They are all tricks. You will often hear the people who perform these tricks, referred to as Illusionists. They have perfected a way to trick the people watching in to believe the illusion. No one can really levitate.
I have watched one episode of Breaking the Magician's Code where they showed about that trick, the person that was flying was actually held by very thin ropes, so thin that they can be invisibly projected on the camera. These ropes are connected to the man's body and to a crane, parked on a far place, that manipulates the levitation of the magician.
