impossibly strong. literally beyond the power of flesh strong.
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 how massive they are
Perhaps you are ignoring the boat likely has over 1000lbs of buoyancy in it
Looks like I'll start doing more lat pull downs
i weigh more than air why would i float up
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)
>i weigh more than air why would i float up
>i weigh more than air why would i float up
>i weigh more than air why would i float up
you would have to attach some weights to your legs to make this work.
Start with a plastic bag over your head and fill your socks full of rocks..
>what is carbon dioxide
what the frick is this bait
water would just fill the whole thing up, what? You homosexuals 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?
Nice bait, the reddit spacing completes this
He is right?
The water would simply fill the gap, its that simple.
Utter fricking moron detected
You never tried shoving a cup upside down below the water as a kid?
Damn wooden boats are as airtight as cups now, pog
Boats are well known for being completely porous and failing to keep water out
Yeah thank God we had alien technology.
Airtight and watertight aren't the same thing.
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 moron? 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?
They're in shallow waters. You ever heard of a diving bell, genius?
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?
No, really. Google "Diving bell", midwit.
HAHAHAHAHA FRICKING moronS! GET BAITED!
>I was only pretending to be moronic
Somebody googled it.

Fricking moron

read it and stop posting
Outside of the moronic buoyancy issues an upside down watertight simple boat performs the exact same task as a crude diving chamber
If they just tied rocks to it in the image it would be fine
>they're at least 4m deep
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.
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.
it is compressed from below
Oh yeah I suppose it is.
There's a big difference between saying "The movie fudged the numbers a little bit because it's more fun" and saying "Lmao that's not how it works, the boat would just fill up all the way and they'd suffocate while their lungs burst lmao"
You're a moron. The only unrealistic part is them being able to keep the boat down. The airpocket existing or them breathing from it is perfectly possible.
>You can't even go without equipment past a certain depth because the water crushes your eardrums, eyes and other soft points
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.
Yes, wood is airtight. If you think it's not, you are antisemitism.
Got me good
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.
I think you would just need to be extremely dense
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.
