    your strength literally wouldn't matter
    the boat would want to correct itself or float up
    even if you could keep it upside down, you'll float up towards the surface

        Perhaps you are ignoring the boat likely has over 1000lbs of buoyancy in it

        the buoyancy of that much air would need like a literal ton to keep it down

        it's not about weight, it's about density and buoyant mass. how does a metal air craft carrier float? it's heavier than a skyscraper (literally)

    what the fuck is this bait

    water would just fill the whole thing up, what? You gays think boat design features some sort of void that repels water?

    I'm not even considering the fact that the boat would turn and since you're fully underwater you're very easy to move around. Who thought water wouldn't simply fill the gap? Why would there be a gap?

              That's true, but in most cases watertight surfaces are also airtight. A boat is definitely airtight.

        You truly believe the pressure applied by the water in this case is same pressure applied by the water in the OP?

        No, really. Why won't the cup fill? Because the internal pressure of the air (trying to escape) is higher than that of the water trying to go inside. You believe that is the case?

        Are you aware human lungs BURST with much, much less effort? They're at (some part of) the bottom of the ocean, and you think your little physics experiment plays here? And I'm the retard? You can't even go without equipment past a certain depth because the water (only the water, with no hyperpressurized atmosphere like in the OP) crushes your eardrums, eyes and other soft points. And you think you'd be fine in a bubble of air surrounded by such water?

            You don't understand. Your little cup thing works with a little centimeters of water attempting to push the water in, no more. They're at least 4m deep. All the water placed directly upwards would push down into that little gap of air.

            Are you female by any chance?

              That's nothing. Every 10m of water adds 1 atmosphere of pressure. So their air pocket would shrink to half at 10m, to a third at 20m, a quarter at 30m etc.

              No, really. Google "Diving bell", midwit.

              Diving bells need an external air supply when going deep enough for the air to compress.

                Air doesn't just compress if it's not even touched by compressive forces because there's a bell in between. Are you stupid? The air is for the length of the excursion.

          You're a retard. The only unrealistic part is them being able to keep the boat down. The airpocket existing or them breathing from it is perfectly possible.

          Thing is you're 95% water yourself, so you don't feel the pressure. Only if you dive/surface too quicky.

          Deepest dive without gear was 250m, which appears several times deeper than OP pic.

    You'd just need a heavy enough boat to counter the buoyancy of the air and then it's not even a feat of strength.

    You would have to sink the boat to even get it down to that level and sinking means no air so yea, it's impossible. Like others have said, with enough weight on their bodies, theoretically, there is a point of enough downward force that could push the bubble down and displace the water but that force is guaranteed to rip a human body in half.

    It's not really a matter of strength. It's more like being able to anchor yourself so you can actually hold yourself down.
