What is the scientific explanation for the rumble noise inside Devil's Cave system?

my band practices in the white room.

You play with Cream? That's awesome! My band is "Skim Milk." We play light rock.

Air Bubbles on the Ceiling make a Rumble Sound that my Wife can't stand. My Wife and I were Cavern Diving Orange Grove and we were watching some Cave Divers come out from the shallow tunnel and our bubbles were moving on the ceiling making a noise that she felt uncomfortable.

She has good instincts. In unstable caves, those air bubble rumbles can (and sometimes do) cause serious percolation, and even rock fall.

Especially if those bubbles make it up into a fissure that holds debris. Won't cause a collapse,but will look like Niagra falls.

Hopefully your wife doesn't read Forrest's comment below.

And shame on you Forrest, if she does.

Is his a case of being too PC? One should never say things that might make somebody uncomfortable, whether they are true or not? It worries me that there is a growing tendency to want to live in a bubble (so to speak) where all things are sweetness and light.

Yeah, likely air. Now if you want to hear a real rumble check the Amtrak schedule and dive Edwards...

Tursiops,
I think Michael might have been joking a bit, although I agree that the political sensitivity BS is a bit out of control these days, I don't think that's what he was going for.

Ok, thanks. I guess he hit my hot button, which obscured my sense of humor.
