So I'm reading Cormac McCarthy's The Road, which all takes place in some vaguely defined post-apocalyptic setting that seems to be the aftermath of a nuclear war, and there's a scene where the main character finds a can of Coke and gives it to his son. The father first pops the top and sniffs it, and carbonation tickles his nose. The book doesn't specify exactly how long ago the war was, but -- given that the kid was born days after it happened, and now seems to be six or seven -- well, that Coke's about six or seven years old. That it still hasn't gone flat doesn't strike me as impossible, but it does make me wonder how long a sealed can of soda pop would retain its carbonated properties. Anybody?
