Is going 10 feet deep deadly?

That’s what I always thought was the issue. That you couldn’t push the volume of are contained in the entire tube. Never thought about the pressure…now I fell dumb. At least you fixed my ignorance!

Ok

Why wouldn't you breath out through your nose?

I came here to mention the pressure discrepancy. 👍

Pressure against your lungs will not allow you to breathe in

If you have any law questions go ahead and ask, I specialize in bird law though

Well if you got enough water into your lungs the pressure would equalize right

@@CharlieKellyEsqOhh ok

@@CharlieKellyEsq is it legal to marry interspecies? I'm a cockatoo and want to marry a chicken, would like to know the ins and outs abt it.

The oil lubricates you lungs to help the air slide in easier

@@LawrenceTimme 🤣🤣🤣 you're so right!! Then an oil free compressor Is NOT a good idea 🤪

Just use olive oil. Maybe a little garlic and a sprinkling of parmesan cheese. Delicious.

The replies, omg

You'd not be able to keep the air in, the failure point is your tongue or throat not your lungs, so you'd just be forced to exhale.

@@bscutajar No, the failure point is the alveoli in your lungs. Very easy to damage, they'll rupture much sooner than your diaphragm gives way. Think about it, if your diaphragm was the weak point, you'd just exhale on the way up and it wouldn't be very dangerous. Part of scuba diving training is learning to always be exhaling just a little bit whenever you're not taking in air. ALWAYS. Trust me, when I was getting certified, I forgot after taking a break and floated up about 3 feet and my lungs _hurt_ for days after

I heard that deep diver has to hold themselves at certain depth for a set of times before raising out of the water to avoid sudden un-gas of the dissolved oxygen and nitrogen in their blood that will surely be very painful and lethal as well.

@@bscutajar False. Pulmonary barotrauma(over expansion of the lungs) is very real and very dangerous risk in any compressed gas dive.

@@axe4770Not even deep divers. You can build up dangerous gas levels from even like 60 feet of water. It depends on how long you are underwater at different levels of depth. Learning how to safely ascend from diving is one of the most important parts of your training. Also a reason why dive computers are an absolute lifesaver

Now I know what SCUBA means, thanks!

I didn't notice since he didn't capitalized it.

​@@lucasthechThat should be common knowledge

@@RealMTBAddictDon’t shame them for not knowing, I’m sure there was a time when you didn’t know that.

@@colorado841 My bad, sorry.

True

Yes I can't believe they completely overlooked this. They should have used a vacuum hose

Yess

That's exactly what I saw too! I kept thinking, how come I'm not seeing any air being exhaled? Are they trying to exhale back into the hose that's got kinks in it?

The rubbery nature and unnecessary length of the hose definitely contributed to the issue

Whoa. I hadn't ever considered about sneezing underwater. I don't ever recall having the sensation. Interesting.

​@@huykedyeah fr I think I'd will through it if not fuck me 😂

For me, I recall a slight/quick (but sharp) inhale at the exact moment RIGHT BEFORE the actual sneeze… Maybe it's not the same for other people… But if it is, then wouldn't you end up choking on the water that your body is trying to inhale in order to sneeze??? 🤔 (Sorry if what I'm saying doesn't make a lot of sense.😅)

@@savage___stomp It makes perfect sense. You just have to prevent that by controlling it. I do best when trying to limit my sneezes by breathing out my air, then my sneezes are mostly just lung convulsions without moving much air.

The mermaids at wiki wachi here in Florida have to learn to breathe with a underwater hose. They train for months before being allowed to do the show.

This answers the question I had. I was confused about how divers can use SCUBA gear if their lungs aren’t able to inhale.

@@KyleT1990 Glad I could shed light on that for you.

The first stage of the regulator regulates to about 150 psi above ambient, the second stage regulates to ambient. I used to service and repair SCUBA equipment in the '90s, not sure of the exact numbers but they're close.

Thanks for this, I was wondering how scuba divers can breathe

​@@HighlanderNorth1Thanks, we aren't interested in your scam scheme and we actually want to live when we go under water

Crazy... You inhale more air per air and don't even realize

@@thecoolereraserii6082 Sometimes it's regular air. Sometimes it's a gas mixture. Depends on how deep you are.

Interesting. Thanks for explaining that. I wish this dummy would have put that info in the slide also

I love watching the dive talk channel and never learnt that!! Does the lower air pressure affect the amount of air you inhale/absorb?

@@JUNIsLuke The volume of your max inhale doesnt change( it's fixed by lungs/ribs size). The deeper you go, the more pressure there is, meaning for the same volume you'll need more and more air, therefore the deeper you dive the faster you will go through a tank. Naturally that does come with side effects( like decompression sickness, gas narcosis, etc), but smart people invented ways to diminish them( as much as possible).

Wait but how is inhaling from the tank different? Is it because it's pressurized?

@@zacharydefeciani7890 Yes, the tank is at higher pressure than the water and is reduced by the regulators in two stages. So, pressure of air inside lungs = pressure of water pushing from outside.

@halfsourlizard9319 I wrote this and then he started talking about the compressor so I had a feeling that was why

Confirm x2. For one of my PADI certs, we practiced one of those ascents where you blow bubbles and swim to the surface. Your intuition looking at the distance is that it's a long way to swim on a single breath of air, but that's the thing... It isn't really a "single" breath. As the air expands, the bubbles just keep coming, and it's easy to go that far with a constant exhale. Very weird experience. It's like having a magician pull an infinite scarf out of your mouth.

@@clairecelestin8437 Yeah, I knew that's what ought to happen in theory, but it was still bonkers to exhale and exhale and exhale and still have air.

Did he die then ?

source: trust me bro

@@best0616 his body was eventually recovered yes. This happened many years ago and I dont even remember how I heard about it but yes he did die. They think by the time he started passing out he couldnt drop his ballast in time and surface.

Guy should have used two hoses.

@@babyboo600 I have none. I think at this point I heard that story 15 years ago on the radio I think. I honestly would love to know if i am remembering that right or not

This is what I was thinking of too - what about a stainless still tube or smth

Yep, in the movies they usually used some sort of Reed/Bamboo. Rigid wall, Bigger the Bore the better. Still not going to do much though to help below a few feet. Your mileage may vary! 😁 Mike in San Diego. 🌞🎸🚀🖖

yep, I'll believe its a pressure issue if they use a pipe or supported tube.

Came here to say this :)

I bet on this theory😂

you would only use the hose for intake and exhale through your nose into the water. but the reason this won't work anyway is because the pressure of the water presses the hose closed. You need something like a hollow pipe that will stay open.

@@headhunter1945 You can find videos of people trying that with a hollow pipe, still doesnt work deeper than 1-2 feet because of the pressure needed to inhale.

@@markopolic9964 What if you brought an upside down bucket with you with a weight attached. You could then use that as an air source because it would be compressed at the same pressure, right?

@@jimaylan6140 the air's pressure doesn't matter, it's your body's pressure. the water is crushing your lungs closed and they're not strong enough to expand. the way scuba suits work is the air tank actually senses how much water pressure there is and forces air into your lungs with that much extra pressure, so it forces your lungs out from the inside. that's why as he mentions divers must exhale before resurfacing because all of that pressure will be in their lungs and without the water continuing to press it in then it'll explode

Yea me too 😂

Never been outside or what?

dont do that, except if it has a exhale valve. Cause else you inhale the air, that you just exhaled and die.

@@neutronenstern. Exhale valve, that's genius, now I can safely try this at home!

@@neutronenstern. the pipe was fairly narrow. I didn't try it for long.

@@neutronenstern. It has to be a really wide or long tube to hold that much air, unless you are breathing really shallow breaths.

@@neutronenstern. it should work aswell if you exhale through your nose instead of back into the tube right?

Good advice for anyone, really 👍

@@Parmetheus It's actually... Never HOLD Your Breath!

@@thomasfplm That's what I learned in the YMCA program.

@@majorbuzz, and I learned from PADI.

JESUS AND GOD LOVES EVERYONE SO MUCH TURN TO THEM BEFORE ITS TO LATE

Another conversion they taught us in diving class was 1x atmospheric pressure (14.7 psi) for every 10 meters, in line with what you both mentioned.

Yeah I came here to say the same thing, you'd be hard pushed to survive 433 psi water pressure

@@beardy_welder You'd be hard pressed at 433 psi....

@@gorkyd7912 I didn't even realise I'd said it that way but now you mention it 😂

You can get a filter for that. They are used for air brush painting. I don't know how good or suitable it would be for breathing, however.

@@matchrocket1702 Yeah do not do that. Airbrush clean and lung clean are different worlds. It isn't even so much the quantity of contaminant as it is the type.

@@Teth47 Good advice.

I highly recommend never doing that again. You could have easily caused major problems and even killed yourself. It isn't hard to give yourself a embolism with what you were doing. I know it's fun to find ways to stay under water, but it's also very dangerous.

compressors for breathing air need to be oil free or they need a scrubbing system plus a carbon monoxide detector. oiled compressors can actually produce carbon monoxide which will kill you.

I'm doing it right now....the main issue so far is texting under water. Its hard.

@@jackiec498 Yeah, I can imagine. My touch sreen never works when I'm underwater. Might try a laptop next time.

@@weppwebb2885 I'm sure you would need to bring ur PC to the bottom of the pool for this...

@@rey_nemaattori I'm not sure about the logistics of taking electronics underwater so I'm just gonna try this with a toaster instead

Very impressive! I was able to do the same at 8-9ft, but that apparently "doesn't qualify" due to my "highly suspicious green blood and metal skeleton"😒

I did that with a plastic PVC pipe, we had a pool at a holiday home and i laid flat on the bottom and basically stayed under until i got bored of it. I was kinda surprised that they only used the flimsy tube and not something more solid to compare to, or at least included the vacuum in the tube in the explanation. He didn't need to show the bottle and the bag, he could've just mentioned how the tube clogged up because of the pressure. But yeah, he now made it sound as if it's not possible at all to breathe underwater.

​@@Games_and_Musicbecause he doesn't know what he's talking about. And people listen to this. Science lab my ass. I'm a certified commercial diver. Check my comment in comment section. I lay out how he's wrong.

You can see multiple times how the tube is collapsed down near his mouth. Of course you can’t breathe in lol.

@@brendanberry7403 😆😄😆😅😂🤣 it amazes me how he didn't catch that. Seems so simple and easy to notice.

4/3 the pressure (1 and 1/3 atmospheres) would mean 3/4 the volume.

Ty so same loss of volume from 0 - 10 feet as 10 - 30. As I recall in from my scuba training in shallow water even a couple of feet can cause your lungs to burst if you take a breath of compressed air hold it then rise in the water column. This is why one of the rules others have mentioned is you are always breathing in or out.

Videos like this one made early youtube. Could have also been from 2009 in some kind of mythbusters episode

😂 man said rating of vessels.. funny but good info

That's only an issue if you have breathed in at depth(and thus: under pressure). If you hold breath and dive, the air wouldn't rip your lungs apart. Since compresser diving isn't a regular thing, this generally only happend when SCUBA-diving, and they'll train you ad ifinitum about not holding your breath while ascending.

Still wouldn't work with all the pressure on your body.

still, better include the warning before people go test this for themselves in deeper waters without proper knowledge ;p

@@yannicfreson2974 the person above you is suggest there should be MORE WARNINGS on this video...because its more dangerous than shown.

@@diox8tony i misread that as "impossible", my bad xd

Thats mostly to reduce nitrogen in the blood, not related to the volume of air in the lungs. Two problems related to breathing in increased pressure, but different ones.

I dive alone quite a lot. Needs additional training and equipment. I prefer it to going with random buddies - seen too much BS. The risk of them being a liability rather than a help is there.

@@svr5423, ideally, you should have someone who you know and have enough training. I do recreational diving, not professional, but even among professionals I still hear the first rule. The second one I heard professional underwater photographers say they break to get some pictures.

@@thomasfplm Professional divers tend to go in teams, same with technical diving. But they are trained for this and the requirements are much higher than for recreational diving. Under PADI, you can for example do the Self Reliant Diver course. But yeah, standard is with a buddy and there should be a reason why someone would deviate.

@@svr5423, that's true. Also, in this case, the main point was the second rule about not holding your breath, that is more relevant to the subject of the video.

There're already videos of people trying that with a pipe online, they couldn't go deeper than 1 or 2 feet.. At 1 meter, the added pressure is about +0.1 bar[ 1bar being the pressure of atmosphere at 0m]. According to ncbi.nlm.nih maximum negative pressure humans are able to make is about -0.1 bar, meaning you'd have to try your hardest just to be the same as your surroundings on 1m, and you'd need at least a bit more to start inhaling.

You're on the right track. Certified commercial diver here. He's wrong. I laid out why he was wrong in the main comment section.

Based on doing this as a teenager, breathing at 2 1/2 feet down (mouth to surface, lying face up) through a rigid tube is brutal. You'll only be able to take a few dozen shallow breaths before your diaphragm tires out. You need to keep your lungs near the point of maximum inhalation strength, which is somewhere around the mid range, so you're straining hard to keep from exhaling too much then really hard to inhale a bit. I think his "3 to 4 feet before we couldn't take a breath at all" estimate is high.

@@jmodified that's because you're trying to intake and exhaust through a single tube with no one way valves. Maybe I should make a KZfaq video showing why he's wrong.

@@charlestannehill7537 Sure, with a check valve you can inhale at somewhat lower pressure because you can relax between inhalations. And, you could attain much lower pressures by repeatedly using mouth suction, though I'm not sure if you could get air in fast enough that way or keep it up for very long. Mouth suction is much stronger than lung suction, maxing out at about -7 psi, so the limit would be 15 feet or so. But this video was about breathing through a tube (no valves), so how does that make him wrong?

@@jmodified he was referring to as why a snorkel with a longer tube wouldn't work. And he's wrong, plain and simple. Who says a snorkel can't have a one way intake valve? And a one way vent valve? Unified into a single mouth piece? While being ridgid with a float ball attached to have vertical buoyancy? Anyways, this was very poor half assed attempt at busting this “myth". Which he failed and got wrong. He didn't understand the principal of lungs only being able to pull and push so far. Nothing to do with pressure. If air is only going in one direction, there's no carbon dioxide to rebreathe in. And your lungs have to do no work pushing it out. So it's not as stressful as you might think. At 33 feet, you have two atmospheres pressure. And every 33 feet after that. Even at that depth (33 feet) with the proper setup to what I'm talking about, it would feel like being able to take half breaths. Basically your lungs strength to intake air. And not everyone is the same. You learn that quickly in dive school. He could've asked ANY submariner, commercial diver (like me) or deep sea rescue team. But he didn't. He took that jank ass tubing without understanding the core principles. Now that I know he's wrong on this, I wonder how many other things he's wrong on. I will not build it, nor do I care to build it. I can slap on a Kirby morgan 27 and weight belt and walk on the bottom. And I live in Oahu. So, yeah....

I don’t really think so because you’ll still be “pushing” against the hundred/thousand pounds of water again

@@officiallychelz6508well no, sucking through a small tube would be much harder than sucking through a large tube, it’d be like breathing through a straw. I’m curies if they keep their head in a whole tube would they be able to breath

@@pennywisenibbles4949 I’m not quite sure about the tube thing, because it’d have to be airtight to make sure there’s no water that’ll come through the open spaces around the neck/head when the tube is out in them. And I imagine it’d be hard to take it off (the tube).

@@officiallychelz6508 well yea but the point being I don’t think it’s because of the weight on the lungs I’m pretty sure it’s because he’s trying to suck air through a massive straw

It's not the pipe. It's his lungs

Tube rigidity doesn't matter. At 10 ft depth you're essentially trying to breathe with 300 Kg weight on your chest.

@@saitama2379 Why doesn't it apply to divers with a tank?

@@Kolbein837 They use a regulator which adjusts the pressure to that of the surrounding water.

like 0 feet

the problem is that one's diaphragm cannot overcome the pressure at-depth; gas mix has no effect.

You could go 80% deeper ofc😂

You would damage your lungs if you breathe pure oxygen.

12 feet. Any deeper and it becomes toxic. (Assuming 14.7psi atmosphere pressure at the surface of the water). I was able to pull air at 3 feet, but just barely. Any deeper and the water pressure just pushed too hard.
