He's a braver man than I would be - holding the combustion chamber right next to his right ear/head/neck when he fires it off. If anything goes wrong with the cheap PVC pipe he won't make it to the hospital.

Soon-to-be Darwin Award winner? :-/

Well, the guy did seem to know what he was doing, but yeah, holding that combustion chamber so close to his head, definitely qualifies for the "dangerous" category.

My alltime favorite Darwin award was the story about the guy putting the JATO tank onto his Impala (even though that was later confirmed to be fictional)
