Okay, I am going to disagree about him being an idiot. I have seen this guy perform some masterful illusions. He is no novice goober.
Most illusions involve the Appearance of risk rather than actual danger. I'm sure the trick was rehearsed numerous times before going on camera.
But, as the master magician Florian Zimmer would say,.....scheiss happens.
Now...did something actually go wrong or was it planned to look that way?
