He is bad if you understand how most of his tricks work.

The voodoo one is all fo sho. Nothing real. The blood is something he presses and it comes out in a little hole which is colored to look like his skin.

With the knife one he talks to people in the back and they tell him where it is.

With the shadow one its probably an easy explanation.

As for how he levitates. It is magnets. Or artificial gravity.

Making people dissappear is common throughout magicians.

The needles thing can be explained as his belly button is a fake. Already filled with needles.

As for how he goes through a window. It SLIDES UP. The guy inside is his accomplice.

If you have no idea what I am talking about then watch his videos on youtube.

End.
