I posted these before watching them all, but some of these tricks are damn good. Did you see the one where the guy pops a woman's cell phone into a bottle, then has a friend call the woman's cell phone while it's in the bottle? Evil spirits? Or was the woman a plant and using some props bought at a musician's supply shop? I would have to think on that. Hmmmmm. Occam's Razor says evil spirits. Definately.
In his concluding video, Xendrius uses a very talented mask changer to prove it was demons. But mask changing has been around for many years and I've seen some pretty bad ones (which always screw it up for the good ones). It's done through the use of silk screens that can be snapped into place in a fraction of a blink. Even cameras can't detect it. In fact, on some you can actually see the wrinkles in the silk.
Now all this doesn't mean I don't believe in evil spirits. I do. But there's a reason these things are called tricks. I've seen Kreskin do some amazing things with the power of suggestion. I also think he's a gifted reader and don't know if he's a psychic or not, but both he and Randi have million dollar offers on the table.
