Watch? I was like, "Dude! You're doing it wrong!"
Ok... um... Ya see, my dad drives a cement truck. I hang out at his shop soemtimes, and they do use explosives to clean out the barrel of a truck. But, the guys at the shop drill holes in cement that's as deep as it was on the show. (I was watching the guy with one arm do that. He let me get in the barrel to get a good look.) Anywho, then they put a LITTLE explosive material in there (wasn't TNT, dad's not sure what it is either) to crack up the cement where they can chip it out with air-hammers and sledge hammers. Dad tells me it can take up to a week to clean out one truck.
He just told me he had to do it to his one time. Apparently, a hydrolic line burst and the drum stopped rotating with a 6-yard load (that's a half-truck).
Ok, so babbling done with, I wonder why the Mythbusters didn't just go to a redi-mix plant or two and askhow they do it. Dad says it's a pretty common practice... *shrug*
