That Was a Bottle of "Pop!" All Right...

Had a bit of a laugh while making lunch. There wasn't quite enough RC left in the two-litre to fill the tumbler, so I upended the bottle in it to drain while I went downstairs to get another. As I came back up the basement steps I heard a soft "Pop!" and a clatter. Thought at first the kittens were doing something, but found the empty bottle rolling across the kitchen floor. Quickly figured out that enough gas pressure built up from the evolved CO2 to push the last of the cola out, which buoyed the bottle high enough to overbalance and fall.
