There’s few things worse than a glass of flat Coke. OH WAIT, a glass of Pepsi is far worse. But anyway! An incredibly bored person wanted to find out exactly when Coke went flat so he timed it.
His method, which is completely unscientific, was to pour a glass of Coke and then count the bubbles that existed. After 34 minutes, only six bubbles were left. I personally think Coke stays good for at least two hours (it’s heavily carbonated, yo!) so I call shenanigans on this guy. Someone get Mythbusters on this. [BuzzFeed]
