      I’m convinced people that “can’t” just don’t know how.

      It’s the same movement as closing your throat off so you can open your mouth underwater, and you just push “up” past that till it puts pressure on the eustachian tubes, and the rumble is your muscle fibers contracting against that which resonates on your eardrums.

      Anyone can do it, it’s just hard to explain

        That’s a minor sound when I do it if I understand correctly. Audible but light. I can flex the muscles in my jaw/tongue as one would to attempt to pop ears, but pushing out from the back of the mouth and pulling my jaw backwards. I think it slightly restricts blood flow and makes it turbulent past the ear. Sounds like pulsar tinnitus (probably not relatable) but constant as long as I hold it.

          Yeah, that’s it.

          I think some people just do the “water lock” thing to close their jaw off naturally to try and stop a yawn, and that’s how they “discover” they can do it.

        Ooh, I can make a little rumble thunder happen if I do that! But why would anyone want to? And weirdly, just yawning doesn’t really do it, but squeezing the eyes while yawning does. Huh.
