I hate this cop-out >dude, the movie has orcs and magic and shit, who cares if the entire physical law is changed just to fit one stupid trailer-bait scene in?
It's not a copout, it's acknowledging that fiction isn't beholden to realism, and that this is especially true when other elements are explicitly unrealistic. Expecting an adventure movie to conform to the laws of physics is nothing but pedantry
The idea of having a bell shaped object trapping air under water is perfectly possible. It was how early deep divers were supplied with oxygen without needing to resurface. However, said bells were ballasted with heavy cast iron elements.
In OP's pic, while the boat could perfectly trap the air if properly forced into the water, two men wouldn't be enough to keep it down, especially when the two men natural tendency is also toward the surface.
Air is lighter than water so it pushes upwards to get free from water, a human body has air in the lungs that also pushes him upwards, they would need weights on the boat to keep it down since 2 men wouldn't be able to hold it plus weights on them to keep them from also going upwards. they would run out of oxygen fast and all that weight would increase the effort making them consume the oxygen faster
Why not? For every 10 meters you descend into water you gain 1 atm of pressure. Humans aren’t adapted for being under high pressure, so becoming pressurized has some serious consequences. According to Boyle’s Law, there is an inverse relationship between the pressure of a gas and the volume it has. The higher the pressure, the smaller the volume. In other words, as you descend to an area of higher pressure (i.e. under water) gas compresses proportionally. This means that in the case of Jack and Will, they would have quite a small volume of air stuck under that canoe – not enough! And since they are breathing in oxygen and expelling carbon dioxide, in conjunction with exerting themselves, they would quickly run out of oxygen. Buoyancy would be another factor – they would have to have huge weights attached to the canoe to keep it from bobbing to the surface. These are only a few reasons why this is impossible – think again, Captain Jack!
>inhale gas from inside the canoe >exhale gas into the water >displace volume of gas from inside the canoe to outside
they breathe until the canoe fills with water
wow.
main problem with this is if they breathed the bubbles underwater outside of the canoe, the british would spot the bubbles at the surface. If they breathed them into the water under the canoe, it just goes back up into the air
Jack and Will were barely 10 meters underwater, the camera pans and you can clearly see the dock above them as they walk along. They only appeared to have walked for a few minutes, if that. The only thing that makes it unbelievable is the weight due to the buoyancy.
look at this fricking nerd hahahah you know that you'll never have sex right? you're probably an asian or a streetshitting pajeet. I've seen a lot of guys like you trying to force your le scientific facts down everybody's throats and i always wanted to tell you that when you're gone the girls laugh at you and call you a bookworm loser who spends his nights studying to better his life. Eventually you'll find a used up roastie with 3 Black person kids and you'll marry her. She will still cheat on you with a white guy. Always remember who's the real boss of this country and we can get rid of you people whenever we want.
Wrong, the air bubble is too stronk and is impossible to keep down. What they didnt account for is the massive weight of jack sparrow and turner's balls, they did flip a whole black pearl after all
>boat full of air >floats >can hold multiple people and cargo and still not sink >turn boat around >magically sticks to the bottom
You don't even need to know the absolute basic physics that debunk this. Just basic logical thinking should tell you this is impossible
So it's only possible if the life boat is dense enough to maintain a relative neutral buoyancy while holding an X sized air pocket. So now you just have to solve for X in the hypothetical. The problem is the air pocket is going to be too small for two people to continually take breaths to make it a distance of what looks like about half a mile.

Is this possible?
Pretty sure myth busters determined you could do it with a smaller air pocket where Johnny and Orlando would have to have themselves weighed down and be totally submerged, bobbing up into the air pocket to get a breath before coming back down to hoof it every 30 seconds or so. Might be good for a few dozen yards but not one end of Port Royal cove to the other
>The problem is the air pocket is going to be too small for two people to continually take breaths to make it a distance of what looks like about half a mile.
Oh no, that's quite doable, I forgot the exact number but the air you breath in is made of 21% oxygen and the air you breath out is like 20% oxygen at most. They could definitely last half a mile with that volume of air assuming they don't stop to smell the roses, the problem is keeping the boat underwater.
Ignoring that the boat is completely filled with air in the inside shot, if the amount of air inside was not enough to give it buoyancy, I bet they could swim under this submerged boat, rather than walk on the sea floor with relative ease.
For how long would be unclear, but you don't have to completely fill a boat with water for it to sink, I bet you could fit in a few breaths worth of air in there without it floating.
they neglected to mention that Jack and the other dude whatever in the motherfricking goddamn shi his fricking damn name frickign was are BAPPING furiously to meek feeding the sealed air vacuum.
No, the control panel is in the way.
If the bars weren't there, also no because that's clearly just a toy and doesn't have any propellers.
If it were real and the bars weren't there, it'd fall off the treadmill before it got enough distance to take off.
If it were real, and the bars weren't there, and the treadmill was long enough, it would take off.
I always thought this was a cool scene so therefore yes.
No, but it's a movie with skeletons and shit so it's ok.
moron, you act like skeletons are some fantasy myth…what the frick do you think we turn into after we die?
Ectoplasm?
gods not real anon neither is the supernatural stop seething and cope.
I hate this cop-out

That's simply not possible. I don't find
this funny anymore.
you've never done this in a pool?
wow you're moronic
They are a little deep to be able to hold down the boat with their weight.
You can't even do it in a pool.
> It never was supposed to be. Why isn't it possible?
>It's just not.
Why not you stupid bastard?
>Because I tried that with Paul Allen in Yale just last weekend.
Why isn't it possible?
It's possible if they weight 2 tones. So it's only feasible if it was your mother

Why. not. you stupid bastard

It’s just not you stupid bastard
Because I had dinner with him twice in London, just 10 days ago.
Yeah but they’ll need to be super strong
The short answer? No.

The only non-moron in this thread. Although non morons don't feed moron bait threads so I guess I'm part moron too.
What if they breathed the air in the boat but exhaled the carbon dioxide underwater?
>inhale gas from inside the canoe
>exhale gas into the water
>displace volume of gas from inside the canoe to outside
they breathe until the canoe fills with water
wow.

this was debunked btw
you can totally do it
Given how bright it looks, there, they're probably only, like, 20 feet below the surface.
>what is a wienerpit airbubble
moron

that's not a short answer
short answer followed by the long answer moron-kun
you're a fricking moron
I’ve done this exact same thing when I raided the HMS QE for grog. So yeah it’s possible
It doesn’t appear to be that deep underwater
What if they brought some plants with them
>plants producing oxygen
This has been debunked as leftist liberal propaganda

Dude chill...
>anti science/logic/reason
You just know whos behind that post.
What if the boat was made of metal?
It would rust
i did this with a big plastic tub in my friend's pool when i was a kid so definitely yes
Yep they did it on mythbusters
Is this a psyop?
yeah the glowBlack folk are monitoring google/youtube search now
Wrong, the air bubble is too stronk and is impossible to keep down. What they didnt account for is the massive weight of jack sparrow and turner's balls, they did flip a whole black pearl after all
yes.
Nope, didn't mythbusters try it? Two people can't hold the boat down.
I'm pretty sure MythBusters tested this.
nah, they would float at the surface with this much air under the boat
is this a trick question? If it isn't possible, how did they film it?
>literally shown doin it per OPs clip
are chuds this anti science?
Yes, absolutely.
If they would hang some cannon balls on the dingy we'll yes sure.
Duh of course it's possible uhhhh how did they film it????
I would think the boat would naturally float up.
This. It would take a lot of weight to keep it down
nah, cuz they're holding it down
They're not heavy enough, especially not with filled lungs
what are you talking about? they're literally doing in the pic.
stfu
Of course it is. You see them literally doing it.
How do you think submarines work OP? Of course it's possible. Don't listen to the wannabe scientists in the thread.
Very heavy boat
Imaging pissing in that tube
hows their head is not under water if they walk on seafloor?
Well it happened in the movie, dont know what to tell you. I saw it. So clearly it is possible.
Are skeletons coming alive at the full moon real? Who fricking cares
My skeleton is always alive
if it isnt posible how did they film it?
The CIA wants you to believe this isn't possible.
Yes, boat was made of steel with wood paneling
I think we'll need to have this thread every day for at least 5 more years before this question will be settled
>boat full of air
>floats
>can hold multiple people and cargo and still not sink
>turn boat around
>magically sticks to the bottom
You don't even need to know the absolute basic physics that debunk this. Just basic logical thinking should tell you this is impossible
Which begs the question, why would they write such a scene
Because it's a fun scene and this is a fantasy movie
If you were to weigh the boat down, a lot. You would need so many big rocks that there would barely be room for Jack in there.
what if the boat was really really heavy?
Even a steel boat will float really well. Even with thick walls. Where are they even finding a boat that is designed from inception to sink?
Yes.
t. had to do this for a merit badge
Taucherglocke means diving bell
>You CANNOT do this! Do NOT even try
it's theoretically possible but not with 2 men.
why would you ask a question you already know the answer to?
Isn't this the one where he swordfights on a giant wheel
no. Also the giant wheel is probably more believable than what OP's asking about
They copied the underwater boat scene from The Crimson Pirate. Great film btw and probably the best early Pirate caper.
Yes, you can watch de ORIGINAL scene from 1952 The Crimson Pirate.
I don't think the question was "do air pockets exist"
no
I don't think you understand how buoyancy works.
nah its fine homies dont swim anyways
missing the point, they wouldn't have the strength to pull against the buoyancy
So it's only possible if the life boat is dense enough to maintain a relative neutral buoyancy while holding an X sized air pocket. So now you just have to solve for X in the hypothetical. The problem is the air pocket is going to be too small for two people to continually take breaths to make it a distance of what looks like about half a mile.

>three days
>60 hours
Gettin' some mixed messages
they neglected to mention that Jack and the other dude whatever in the motherfricking goddamn shi his fricking damn name frickign was are BAPPING furiously to meek feeding the sealed air vacuum.
what a man, i would have killed myself 4 hours in tbh.
I should really rewatch pirates.
He also spent that time.
>in the dark.
he had flashlights
or he could just smile
real life is not a cartoon
No, this thread is moronic.

I done it with a bucket in the swimming pool, that works at least
