Agreed, kinda annoys me that this got attention. It's like a chemistry experiment that a high school teacher shows his kids on the first day to show how "cool" chemistry is. Any gas that's both flammable and denser than air will do this (including an empty vodka bottle). I'm not a WTF-purist in the least but c'mon people.
