I can't tell, the second boom where he holds the resistor in place was that on purpose? If so holy shit that's a dangerous way to make the point. If it was also an accident then he is lucky to be alive since he doesn't seem to know what he is doing.

I know this video is supposed to be funny, but I couldn't bring myself to laugh. Too many people die making the same mistakes.

He does know what he's doing and it certainly was deliberate. While most of his stunts probably hurt he doesn't set them up exactly as he presents them (I.e. it's usually not mains).
