Coke Zero Day

I've been a Coke Zero drinker since early 2006 because it allowed me to drink free sodas at my old job continuously throughout the day, but it didn't have the disgusting aftertaste of Nutrasweet-based Diet sodas. I'm still on the Coke Zero bandwagon (as evinced by the 140 cans I bulk purchased at Costco because they only stock it once every ten years), but I still get irritated by Coke Zero's penchant for premature bubbling. You can try this Mr. Wizard experiment at home to see what I'm talking about:

• Take a chilled can of Coke Zero from the fridge and gently pop the top.
• Have a sip or two then gently place the can on your desk.
• Go back to work writing missile guidance systems, or whatever you do, and allow time to pass as time does.
• At some point between 2 and 10 minutes later, you'll hear a ruckus coming from the opened can as if some of the Coke molecules got excited about the new season of Fargo and started a pep rally. The can will start to carbonate loudly until all of the remaining soda is affected, then everything will go quiet.
• Take another sip of Coke. It is now mostly flat and not nearly as enjoyable.

It is left as an exercise for the reader to explain this phenomenon.
