We've all been there: you drop your bottle of soda at some point and when you try to open it, it bursts into foam.
My question is, then: why does shaking a carbonated drink make the dissolved gas escape?

Although Why can't CO$_2$ mix back with the liquid after a soda bottle has been shaken? is a duplicate to this question, I'm not sure it's a great answer and it would be good if someone could come up with a better answer here.
The accepted wisdom is that shaking the bottle creates tiny bubbles and these act as nuclei for bubble formation when the pressure is released. Without these nuclei bubble formation is mostly by heterogenous nucleation on the bottle walls, and that is slower.
However I have never seen a paper that demonstrated this is the case, for example by light scattering measurements on the shaken but unopened bottle. The nearest I've seen is this paper, which seems reasonably authoritative though it's not from a peer reviewed journal. If anyone knows of such papers, or feels like doing the experiment, I'd be interested to see the data.
It is known that the pressure isn't increased by shaking/dropping the bottle (the article I linked measured this) so some form of enhanced nucleation does seem the most plausible mechanism. It's just that it would be nice to see it proved.
