    Plus, have people never tried to push floaties or balloons underwater? It’s not even a matter of strength, you can’t really fight buoyancy. Even a large heavy adult would only be able to force a very small air bladder under long enough to actually swim.

        Could be weighted with rocks. As long as you exhale back into the bag, it would maintain its buoyancy, and would give you 5-10 minutes of usable air.

        That’s not what they are doing here, of course, but it’s certainly possible.
