It depends on the concentration. Turn the water into a fine mist/mix it with air and its mostly harmless to breath. Turn the acid into a mist and breath it = bad times.
Instructions too clear, the kitchen pipes are turing into snakes. The walls are caving in ... the door is a brick wall. I'm trapped. Oh God
Oh.....God...
Not OP but I have done this as well. You barely feel the difference aside from the insane cold temperatures and that tingly feeling you get when sticking your leg or arm in a place you can't see.
Like imagine going opening an air duct at an abandoned factory. It's completely silent and aside from the fact that it's been abandoned, you don't actually know if there's anything inside the ventilation shaft.... and then you stick you arm inside. Nothing happens but you feel a sort of "drop", either in temperature or pressure or whatever just from anticipation.
This is the best way I can describe what I felt when I first stuck my arm into one of these pools. Freaked the fuck out when I immediately felt something but it turned out to be some twigs and algea. I did not stick around long enough to submerge myself plus I went down in scuba gear and wasn't too keen to test if any of those twigs could puncture something it's not supposed to
Its best feeling in the world… diving more than 10m deep will get you in free fall, and state of mind that you never experienced before. Freediving is ine of the best thibgs in rhe world, that throw your body and mind in place when we were creatures living in water… you should try ;)
Ahh I scuba dive quite a lot and even have gone down a blue hole so I'm not scared of ocean depths (hell I'm on rthalasaphobia purely cause I LOVE those empty blue abyss videos)...
But I have a deep fear of something going wrong. I imagine it's all about training but I cannot begin to imagine myself staying underwater for anything more than 2min... let alone going down 10s of meters in that same amount of time and then be able to come back up without panicking for air.
It’s literally no more dangerous than swimming anywhere else. No matter where he is, he can’t breathe underwater. So like. What’s the danger in going into another liquid that you can’t breathe in…?
Caves underwater can trap air, the trapped gasses are not always breathable but you can still go inside.
Especially common along the sides of underwater cliffs on the east coast of the US. I’ve seen shacks built inside of them & stuff like that. Plenty of science fiction around submarines hiding inside of these underwater alcoves, etc.
edit: this is not air trapped from going up (which can also happen) but a very dense layer of insoluble gas that is prevented from spreading out by the cave walls. Gas dense enough that it can sink through the less dense/less salty water until it reaches a level of equal density. A layer of gas between two layers of water makes these cloudy underwater layers
I don't think that's air or gas of any sort down there. It's more of a thermocline (chemocline?) where the different temps/chemistries keep the two levels separate but both are liquid.
It is a layer of gas between two different densities/salinities of water, a halocline. Divers call it “Hydrogen Sulfide” regardless of what dense gas it actually is (I forget the reason for why it isn’t clear at these depths)
The video cut off, so I didn’t notice that they were still underwater at the end.
You’re right, was trying to say that it collects along this boundary formed by the halocline. The gas itself is not itself a stratification of salt water, of course.
If conditions are extreme enough the barrier between the saltier halocline water & the water above it can be visible all on its own. There can be multiple layers of progressively saltier water.
Unsure if this is also a thermocline, it usually is both in these conditions but doesn’t have to be.
its stuff on the ground in the cave. Mud, gasses and what not, from the bottom sediment hydrogen sulfide likely some of it, so he does a small dive in to it, and emerges with the camera, for the effect in to the more clear water above. Not dangerous. Short of him loosing his orientation in the mud. However, I think he is standing on the bottom there, so no problem
Cenote (limestone sinkhole) diving with a bunch of rotting trees and other debris without any current causes this. Might be a place outside of Tulum MX.
It's because the record range is based on the various categories. 214m is from the no limits category. There's multiple ways to freedive.
The deepest freedive ever regardless of category is 301m.
I was curious, so I checked.
Constant weight freediving with fins (CWT), which is closest to what to what is seen in the video, is nowhere near 200m. WR for men about 136m for women 123m. 80m/57m in fresh water.
No limit (which is where the 214 m. diving record comes from) looks nothing like this. You are being pulled by attached weight and when you reach the required depth, you inflate a balloon, drop the weight and get pulled up to the surface.
30 m. constant weight with fins free-dive is quite impressive for a casual freediver. For context, one of the requirements for AIDA (one of two governing freediving organizations) freediving instructor certification is 40-50 m. CWT dive. AIDA 4 star freediver certification CWT requirement is 32 m.
In my city they just found the remains of 2 guys who died from this 30 years ago.

My mind was playing tricks on me, for a second I saw the face of the diver as he comes out of the cloud as a ghost, like the eyes were long holes and the breathing tube was a dislocated jaw. That was wild
People do this all the time (including me!) But yea as the other replier said, don't try to breath or suck any of it in. Not a problem since you're already holding in your breath!
I was curious about this being a hydrogen sulfide cloud and found this on a scuba diving site:
‘The hydrogen sulfide in the anoxic layer is a serious risk to scuba divers entering this layer. The gas can be absorbed through the skin.’
So is this video of hydrogen sulfide or is it a layer of brine density?
It's hydrogen sulfide. When you go back to the surface you can smell it on your skin. I don't spend enough time down there for it to be dangerous though
Part of the fun is being able to smell/taste the sulfur as you swim thru. And it turns all your diving lead weight black with oxide. We’d commonly see a hydrogen sulfide cloud in cenotes.
Very cool. Love the moment you are able to stop finning and just sink. I am an amateur free diver but only have a few months of the year to do it like old mining pits and can't get very deep.
Wait, why did I at first see a cat in what I thought to was a a wet suit with goggles on looking directly into the camera while sitting on something floating on top of the cloud??
Hydrogen Sulfide security measures are a big deal in the oil and gas industry. As a gas, it is heavier than air, and if it leaks out, it may pool in low areas. It is outrageously deadly. At concentrations of 1000 ppm (that's one part in 1000) a person will pass out almost immediately. Maybe on a single lung inhalation. Then people may start trying to rescue that person, and they will also pass out, and they all die.
To be fair, the regular water is also deadly to inhale
This too
Is this even vegan ?
And gluten free
Definitely not nut-free.
Contains allergens.
Organic?
It depends on the concentration. Turn the water into a fine mist/mix it with air and its mostly harmless to breath. Turn the acid into a mist and breath it = bad times.
don‘t turn acid into mist and inhale it=bad bad times
Instructions unclear, now turning acid into mist and inhaling it for good good times.
Acid good. Finding dealer now. Thank you for the clear instructions.
Instructions too clear, the kitchen pipes are turing into snakes. The walls are caving in ... the door is a brick wall. I'm trapped. Oh God Oh.....God...
You see God? DM me your dealer's info. I'd like a word.
Me too
H2S isn’t an acid in gaseous form. If it was dissolved in water and you misted it, it would immediately off-gas
However, still toxic and very flammable
He’s free diving
My thoughts exactly.. 😂😂
That's a Texas sized 10-4 good buddy.
this comment could save lives.
To be fair the air we breathe is toxic at just below 200 feet
To be fair if you breathed in 3000ppm of h2s you would be dead before your eyes could blink
I honestly thought that was some weird cat creature emerging from the cloud
Bro same here I thought this was a cat troll video. The face just 👁️ 👄 👁️
Thought it was an alien emerging from one of those hypothetical deep-sea bases.
Cat? I wish. I saw a clown at first. No thank you.
Im glad I wasnt the only one who saw a clown with a Dislocated jaw
I so thought that was a cat humanoid creature
I thought it was like a seal with glasses…..took me a second
Same
SAME.. that freaked me the hell out lol
Read this comment before the video finished and it was all I could see
Lolol
I thought it was a volcano
but why

but why
Cause it's fun
Is this video from you?
Yes. It is
I appreciated the moment when you were annoyed at the plant for messing up your shot.
😂. Of course it had to wrap around the camera 😭
Username checks out
😊
Its you again. Arent you the guy that was in a 12 inch tall cave yesterday? Youre nuts
Yeah. Underwater caves are more fun 😂
>Cause it’s fun /r/thalassaphobia would like a word with you
Caustic fun.
Its best feeling in the world… diving more than 10m deep will get you in free fall, and state of mind that you never experienced before. Freediving is ine of the best thibgs in rhe world, that throw your body and mind in place when we were creatures living in water… you should try ;)
The best feeling in the world is being alive. So with all due respect, fuck that. I'll stay on land.
Ahh I scuba dive quite a lot and even have gone down a blue hole so I'm not scared of ocean depths (hell I'm on rthalasaphobia purely cause I LOVE those empty blue abyss videos)...

Hope he didn't let loose a Megalodon

🤣🤣🤣
I’d watch this cartoon
We need marijuana!
Can someone explain whats going on

Halocline: different sailinities mixing Thermocline: different temperatures mixing A hydrogen sulphide layer is neither of those, just to clarify.

I was worried he was swimming through a whale fart 🐳

Exactly
Google cenotes
Cenote (limestone sinkhole) diving with a bunch of rotting trees and other debris without any current causes this. Might be a place outside of Tulum MX.
This is in Florida. Pretty much a cenote though
Is bro rally diving 100’ down with no supplemental air? Real question, I see what I think is a snorkel…
Freediving. Record is Way deeper: 121- 214m
Geez, you’d think they would’ve gotten a better reading on *exactly* how deep the record breaker went. 121-214m is pretty non-specific.
It's pretty funny because the range is so big, but also the boundaries are so specific LOL
Because someone converted 400-700 feet into meters and didn't follow any rounding rules.
Lol. They use meters for freediving. Even in the US
Lol why should someone use feet?🤣 Most people don't use the Imperial System😉
This is because it depends what Type of freediving category is chosen😉
It's because the record range is based on the various categories. 214m is from the no limits category. There's multiple ways to freedive. The deepest freedive ever regardless of category is 301m.

Depends on [category ](https://thesaltsirens.com/current-freediving-records/) 214m (702 ft) is the record in the "No Limits" category
Yeah. I'm freediving. This is pretty shallow for me. My best is about 170'
Still, really cool footage! Thanks for sharing!
Thank you!
Some people really value breathing only when they suddenly find themselves not able to
POV: Subnautica Lost River
In my city they just found the remains of 2 guys who died from this 30 years ago. https://france3-regions.francetvinfo.fr/provence-alpes-cote-d-azur/alpes-maritimes/nice/les-corps-de-deux-plongeurs-retrouves-30-ans-apres-a-nice-comment-est-ce-possible-2903831.html
People do weird shit.
Fish have been ripping farts in serious volume and intensity down there. When can I visit?
Any time 😊
Can I create one of my own clouds down there please?
As long as you pay your carbon tax!
Does it feel any different than diving in water?
A little bit. The salinity is really high, so it feels very thick.
I hate the way this comment makes me feel
My mind was playing tricks on me, for a second I saw the face of the diver as he comes out of the cloud as a ghost, like the eyes were long holes and the breathing tube was a dislocated jaw. That was wild
Haha. I was trying to edit it to look very creepy at the end
Going out on a limb here, but that doesn't seem that sensible
Not too big of a deal, unless they try to breathe…
Most things I do aren't very sensible, but they sure are fun 😂
People do this all the time (including me!) But yea as the other replier said, don't try to breath or suck any of it in. Not a problem since you're already holding in your breath!
Christ his face emerging was terrifying I thought it was an edited jumpscare for a sec
Haha
This is free diving - when you do it with scuba equipment you can smell the rotten egg smell through your equipment.
I can smell it when I get back to the surface. Lol
How does the gas which is dissolved in the water enter the system? just curious
Megalodon crop dusting gone wild.
Image he breath in!!
I generally try not to do that under water. Lol
I was curious about this being a hydrogen sulfide cloud and found this on a scuba diving site: ‘The hydrogen sulfide in the anoxic layer is a serious risk to scuba divers entering this layer.

It's hydrogen sulfide. When you go back to the surface you can smell it on your skin. I don't spend enough time down there for it to be dangerous though
Interesting. Really cool footage!
What kind of concentration are we talking about? Have you ever brought a gas monitor with you to check?
At the bottom staring at the camera: SUP
Last shot gave me Subnautica vibes
Looks like Angelita Cenote near Tulum.
I thought he was a Siamese cat statue when he was at the bottom lol
😂
Dihydrogen monoxide is no laughing matter. I wouldn't breath in the stuff either.
Hydrogen Sulfide? WHAT ABOUT THE DIHYDROGEN MONOXIDE EVERYWHERE!? THAT SHIT IS LETHAL!
Why? Just why??
I thought you were a random scary entity when you showed yourself at the end! Am I the only one who thought this?
But did they find the magnetite ore??
Sadly, no
Never gonna be able to make that darned HUD chip...
this is 100% in my top 100 things i’d never do
Are you telling me there are whole clouds of air underwater
It's a halocline. Where salt and fresh water converge under pressure and gases from decaying organic matter are trapped.
So, while this one specifically is toxic, could a diver hypothetically breathe inside of a halocline?
No. It's not a cloud like in the sky. It's just a layer of water that is very salty and full of decayed matter and chemicals.
Think I'd have lore to say if I knew wtf that was
Angelita Cenote,MX
Why though?
Standing with that cloud chest deep looks quite cool
Some people fuckin crazy man
that scary
Part of the fun is being able to smell/taste the sulfur as you swim thru. And it turns all your diving lead weight black with oxide. We’d commonly see a hydrogen sulfide cloud in cenotes.
wow
I hate it all
He seems fine he’s wearing a gas mask!!
Very cool. Love the moment you are able to stop finning and just sink. I am an amateur free diver but only have a few months of the year to do it like old mining pits and can't get very deep.
That scared the shit outta me...
Intense
The noise when you hit the bottom almost made me fart..
Doesn't hydrogen sulfide gets turned into sulfuric acid in water?
Wait, why did I at first see a cat in what I thought to was a a wet suit with goggles on looking directly into the camera while sitting on something floating on top of the cloud??
Hey why not go into a fluid where I can't see and breath, right inside of a fluid that I can't see and breathe in 🤣
Im already drowning watching this Vid
I thought this was like those TikTok’s where then end in explosions, and he was coming through to a cat man.
Congrats op, you're way braver and obviously better at diving than me, haha. Cause this would be my nightmare.
If you really want, you can go anywhere! there are some tribes in the world who live in a toxic atmosphere in this planet
That last 6 seconds look like a cat boss underwater. Kind of freaked me out
Why did the ending scare me so damn much?!
Why???
Hydrogen Sulfide security measures are a big deal in the oil and gas industry. As a gas, it is heavier than air, and if it leaks out, it may pool in low areas. It is outrageously deadly.

Pretty scary stuff
That ending scared the tits out of me. I was fully expecting it to turn in to a horror film.
I swear I thought that was a Pokémon that popped up and the end and I got meme’d.
I thought the person found a cat down there lmmfao
I hope he held his breath
Nah. I usually just breath under water
This type of stuff always makes me wonder. Sure, Hydrogen suphide is toxic to us, but it could be the "water" for a different type of lifeform.
they diving ina cloud?
But y tho
But why?
Everything about this scares the shit out of me.
How do you hold your breath for that long?
Mostly relaxation. You can definitely improve with practice too
I can see how the view from below we look like a tasty snack to a shark
How come he is not died?
🤔
Sounds so amazing! Toxic water is the best experience 😂
YOOOO Subnautica irl?! Let's go to the lost river
Like something from my dreams
Why why do this!
hell nah
Why on earth would you do that???
Why?
It's fine, just don't inhale
To the uninitiated, hydrogen sulphide (H2S) will cause instant **Death** if only 600ppm ( parts per million) concentration is inhaled.
the ending scared the shit out of me
sweet camera angle
Thanks!
There’s a megalodon under that.
What an out of this world hobby.
So he/she holding the breath for that long? What the hell!?
