Why does the air exhaled by the diver drop instead of rise? Is the video being shot upside-down? (Probably not.)

  It's filmed upside down.

    Oh, OK: divers can adjust their buoyancy. Make it high enough and the buoyancy will press you against the ceiling sort of like a negative gravity.

    There also the possibility the video was flipped later.

      Where it says "filmed upside down", pretend it says, "shows the bottom of the scene at the top of the screen".
      • code_duck 5y ago
        Why not just say the video is displayed upside down?
        • hollerith 5y ago
          Yes, that is better.
