@VirtuaSavage is incorrect. The fact that it's a pool does not make a difference. Pressure does not depend of the volume of the water, only the depth. The reason why the diver descends is that there's two forces that work to influence how deep he's inside the water: buoyancy and pressure. Buoyancy is o/f where o is the density of the object and p is the density of the fluid. As water can't be compressed, it's density doesn't change if you dive deeper. However, the density of the body does change! The deeper you dive, the more the air in the lungs (and other parts of the body) of the diver will be compressed, meaning the density of the body changes. This has basically the same effect as breathing out, except it only decreases the volume of your lungs, not the amount of air inside them. So, at a certain point, the diver will become heavier than water, making them sink effortlessly. The pressure is bearable for two reasons: Firstly, the body consists of large parts of water itself, held in place by cell membranes. As liquids aren't compressible, the water in the body doesn't compress either, and the cell membranes are so thin they can't be compressed in any meaningful way either. The only parts of the body that do compress are those filled with air, but in a healthy person, this should only be the lungs, sinuses and the digestive system. All these body parts are flexible, and so they just deform until the air pressure in your body and the pressure of the outside water are equal, making you feel like there's almost no pressure at all. For this to work properly after a certain depth, free divers plug their nose and ears, otherwise the equalization would happen through the eardrums, making them burst. This only works for free divers, though! If you dive with oxygen tanks, you have to do regular equalization stops, otherwise you'd have to little or too much air in your body, and especially the latter one can be deadly.
@@red13emerald The only part that makes me a little confused are the first steps (that are 5m, 8m, 10m and 12m. I know for sure because I've been there myself not long ago) and ad 5-8 m buoyancy is still pushing up. Even ad 10, although less so. In the video he is going down right away. Therefore I am to believe that he went down with his lungs partially empty. That makes the dive even more impressive. PS: the safety rules for everyone else require to use a tether going down the well. It's forbidden to just get to the border and casually jump down. :)
@@petercastelletti8948 "the safety rules for everyone else require to use a tether going down the well" probably he was allowed because he had a few ppl around him? just a thought
Body buoyancy decreases with increasing depth. Depth of neutral buoyancy(body neither sinks nor floats) is at around 10m. Going deeper and you sink like a stone. Though he probably also uses weights as he sinks in rather shallow water, too. Free divers calculate how much weight they need to carry based on their target depth. Swimming/diving against buoyancy costs energy/oxygen -> releases CO2, which will decrease your time underwater :)
@@rearm2046 that infact ain't true. what he is doing is either of two things. One he could use weights that's why he sinks or if he is really good he pushed the air out of his lungs and just sank (obvi this is really hard to do but yea). and the fact that water isn't salty does help but still you can't sink even if the water ain't salt water.
@@nejc2045 what physics are you following dude hahaha damn bro hahahahha salt water and fresh water are different that is why there are boat made to float to the sea water and fresh water
@@rearm2046 read my comment 5 times and you'll see that i didn't say anything wrong. I mentioned even what you said but went into more specifics since I know a lot about diving... up to you if you like my answer or not but read it twice before you laugh at something

Who else is holding their breath while watching this?
Ur mum for sure
you caught me
Your lungs be destroyed 💀
me
Who came to watch this from shorts 😊
me😹
Me
Me😂
Me
🫣😂
Is he still down there?
Yes
@@준수박-l5yhas he returned yet?
@@준수박-l5yhe is I asked the water
Legend has it
Yes i was the water
This is absolutely incredible
I also came here from YT shorts asking myself how he came out of that long journey 😮
Legend has it Hess still down there looking up.
I literally holding my breathe throughout the whole video
(Relatable as 8-9 years old)
We together fam😂😂
Yeah I’d be out of breath in about 20 seconds
this video needs more views.
Oh hell no! I wouldn’t even get as deep as the beginning of the tube
Wow, respect
I watched this along time ago but i just saw short from it so i came back
Excellente!
Why don’t they show him coming back up?????
The guys who jumped with them with camera will handover an oxygen cylinder
he's still there
Amazing 🔥🔥🔥🔥💯
I wish I could hold my breath and stay under water this long, I’d be heaven
That is one DEEP POOL.
Amazing
Sooo I just watch this video on the shorts and I was hoping to find the full video to see if he made it up.
Bro is falling so epic
HOW IS HE SO CALM?!
I wonder how long someone stood there with a garden hose to fill that thing.
nobody talks about how many time this guy must do this diving stunt?
look at how many angles the camera man took.
He went down once on this attempt. There are like 5-6 cameramen
Champion du monde d'apnée Guillaume Nery.
I don’t understand the physics how is he descending effortlessly without any weights on and his lungs full? Also how is the pressure not unbearable?
Cause it's a pool

@@red13emerald well, this being a pool kinda make difference vs sea/ocean as the water isn't salty
How long can he hold his breath?????
only for so long
@@talktalktalktalktalk 🤣🤣
@@talktalktalktalktalk yeah i walked into that one with open eyes. 🤣🤣
7 minutes👍
world record (with oxygen pre-breathing) is 20+ mins, without oxygen it's ~12 I think
Bro maxed out his lung capacity 😅
First of all, I would like to express my respect for going all the way to the bottom, but I would like to see a video of how they made it back safely.
1:57 IRONMAN❤❤❤
amazing!!
Wow
He came back right?
Yall can't trick us we know that's aquaman 😂😂😂😂😂
Who came to watch this from shorts 😁
i hate that hole it just is so dark and scary
이제 어떻게 올라가지?
How does he sink like that?

Je suis jaloux de la compensation hand free 👃
What is the depth on that tube?
Return video?
노래 좋다
So how did he cone up. Obviously, it's with an oxygen tank.
Being underwater feels like your on the moon
its is said that this guy used is also a chain snoker
Yeah l d be out of breath in about 20 seconds
Who came to watch this from shorts?❤😊
Right here 😂
I didn't see him equalize once.... someone explain this to me. He have a nose plug in or something?
Thats nightmare-ish bro, came from shorts btw
凄いなあ…生命の神秘
It seems to be a film adaptation of fertilization.
Anyone in 2024😂
Repect to the cameraman who was recording him WHILE doing the excact same thing
Did he dive?
he just sink
How u dont float up?
Its water not sea water you float on sea because of the salt in water you sink in pool because it is just water

They edit this well

I see why they named it y40 .... like y would I even do this 😂
For the TikTok clout!
40cm
Nah, fk that!!! You cheated me! I need to see him reemerge!!! Swim sir swim!!! 🏊🏾♂️
They were giving him oxygen, couldn’t you see the bubbles at some point?
@@matthewsichalwe926 i never said nothing about him holding his breath.... I just wanted to see him swim back to the top you goof 🙄😒
Ha fiato da vendere..

From shorts say Hi😂
Hi

Who’s here from Reddit 😂

That guys got a set of lungs 🫁
Howwwwww
Camerman never die😂
How did he get back up
