>*Don't they burst because the source doesn't stop before the bubble gets larger than what it can be? (...) The source stopping would just lead to a deflation where it slowly gets smaller if the air hole is still open

To continue my analogy, I prefer to visualize them as flying uncontrollably while shrinking very quickly (but not immediately as a puncture would), propelled by their own deflation discharges...

So, this kind of thing: https://www.youtube.com/watch?v=6CTnTi1Lq60

Sounds like your analogy is more about balloons rather than bubbles. Bubbles make me think of these: https://www.techexplorist.com/wp-content/uploads/2020/02/bub...

I guess you're right... I think of it the analogy more like baloons than water bubbles...
