Mythbusters co-host and explosives geek Adam Savage chimes in with his review of the Lost season finale. "First things first: the explosives. We blow a lot of things up on MythBusters, so I know from experience that last night Lost missed the mark. The 500 pounds of C4, that whole movie thing about "dummy triggers" and fake tripwires-it's all a load of crap. Nobody does that. At least that's what my friends at the FBI tell me." I've never seen the show, but what comes next sounds like spoilers.
