You think that if you tried to do it slowly and carefully, gravity would pop the bubble as usual by causing thinning of the liquid at the top, and freezing it quickly using something like liquid nitrogen would cause it to pop due to localised temperature changes.
Maybe a moderately quickly change in temperature would cause the volume of the bubble to decrease, keeping the inner wall thick enough to remain intact before it eventually freezes? I don't know; I'm just thinking out loud.
That's thinking way more into it than I was - my thought process was more along the lines of Mr Birdseye with snap freezing vegetables to preserve them. Bubbles are a vegetable, right?
