When I open a tap over a water surface, we get to see a lot of bubbles ("half merged in the water") coming out on the surface.

Now what I saw was that two such nearby half bubbles merge to form a bigger one. But I couldn't really think of what goes on at the point of contact between them. How exactly does air gets transferred from one to the other? Another point which I wanted to mention was that in such mergers, the bigger bubble gets bigger and the smaller one vanishes which is opposite to what I read in my high school about bubble mergers.

So someone please clarify what goes on at the interface.
