Is The Street Magic Shows On Tv For Real? No Actors? No Camera Tricks?

On TV, there’s a lot of street magic shows like David Blaine, Mondo Magic, The Mentalist and lots more..I wonder if there are really no actors or camera tricks used by the producers of this shows although they say there are none because no one is gonna sue them if they lied anyway.. If it’s true, is it possible that they use black magic because some of the magic they show are really awesome and i am like cant think of any ways that humans can do them…

Is It Me Or Does It Seem Like The People On The David Blaine Shows Are All Just Bad Actors And Camera Tricks?

i mean, there’s def. more stuff that goes on behind the camera that we don’t see on tv… i just wanna know his tricks
