Just like any other liquid you pushing air into it causes the oxygen to rise. Due to the surface tension of liquids, eg water, which is less dense than milk, the air rises and escapes to the top. But since milk is thicker(heavier/denser) water the bubbles hold on longer and tighter and you get that furious lifting of bubbles.
I’m sorry I can’t explain like I’m five. Does anybody else have a better explanation
