What Happens When You Open a 15-Year-Old Can of Soda [VIDEO]

We were cleaning out the storage room in order to create a video production room and uncovered this gem, a near 15-year-old can of the good 'Doctor'.

What were we supposed to do? Of course we opened it, hoping for soda remnants and nope. No powdered soda, no sticky mess of condensed sugars, no mold, and no creatures. Where in the hell did the soda go?
