The world’s deepest swimming hole, located in Brussels, Belgium. Nemo 33 is a submerged structure with platforms at various levels that plummet down 108 feet! It holds 2,500,000 liters of non-chlorinated spring water that stays a toasty 86 degrees. Divers often use this facility to train, and there are even simulated underwater caves.

Simulated underwater caves

Holy shit, that's amazing.

[–]defiantately 84 points85 points ago

There's a rock-climbing place near me called A.I.R. (Albany Indoor Rockgym) that has a gigantic indoor caving system. It even has zip lines connecting some of the cave entrances. It's also pitch black and claustrophobic so there are points where you'll feel like you're in The Descent. If you're ever in Albany, NY you should check it out.

[–]NuclearExchange 48 points49 points ago

There's a place in Louisville, KY called Mega Cavern that's a decommissioned Civil Defense shelter. It has something like 17 miles of roads inside and there's a zipline tour through some of it.

[–]muffinhunter 34 points35 points ago

Did you catch some sweet nar-nar on that zipline tour?

17 miles deep? That's nothing. Maybe you've heard of a little place called Your Mom.

      I love A.I.R!! Some of those tunnels in the walls get insanely tiny. They should really expand for the amount of time they have been in business, and open a place twice as big. Somewhere preferably situated in a location other than a back street behind a pizza place.

      [–]obotray 12 points13 points ago

      Ups for referencing the Descent. Fighting mutated cave people I can handle...getting stuck in a crack, not so much. That was the scariest part of that flick for me.

      [–]reali-tglitch 2 points3 points ago

      I couldn't breathe during the entire seen where she was stuck in that small tunnel. That was the scariest part of that movie.

        Is it a "dolphin rapist" if you rape dolphins or are a dolphin who rapes things? I read it the other way around.

                            Since the water is non-chlorinated, do they sanitize it with bubbled oxygen? The US Olympic Swim Team practices in pools that do this, and they much prefer it to chlorinated pools.

                              Maybe I'm nitpicking, but shouldn't it say somewhere here that the depth is 33 metres? As in, the reason why it's called Nemo33... Saying it's 108 feet deep strikes me as completely pointless.

                              You sent people to the convention, and you signed the fucking treaty.

                              There were originally 17 countries involved with this treaty (some of those countries no longer exist). The Metre Convention was signed on 20 May 1875 by representatives of the following seventeen States:Argentina, Austria-Hungary, Belgium, Brazil, Denmark, France, Germany, Italy, Peru, Portugal, Russia, Spain, Sweden and Norway, Switzerland, Turkey, United States of America, Venezuela.

                              [–]AFatDarthVader 122 points123 points ago

                              It's a treaty about measurements. Most countries can't even be bothered to observe real treaties.

                              it's was less of a Protocol, and more of an Accord.

                              An Accord some in government were in disagreement with.

                              Some would say that there was no accord in how to work the Kyoto Accord.

                              [–]GAD604 7 points8 points ago

                              Which I find very amusing because Honda has an Accord that works beautifully.

                                    For context and perspective. Some Americans seem to perceive the metric system as some foreign shit, but while it is some international shit, the US has been involved in it since close to its beginnings.

                                    [–]touchy610 13 points14 points ago

                                    Many Americans are also taught the metric and imperial system from elementary all the way through high school. Science and math classes will very often deal with simple-to-complicated problem-solving in metric measurements.

                                    [–]metrication 7 points8 points ago

                                    True that. Jefferson, Franklin, Washington, Hamilton and others were all "metric" advocates before the metric system was invented. Jefferson drew up a decimal measurement system, but his bill to introduce it got tied up in the US Senate and was delayed.

                                    Ten years later, the French introduced the metric system and the US lost out on the opportunity of introducing an international decimal measurement system. /r/metric

                                            That puts the depth into perpective for me. My personal record for depth is 55 M (180.446 feet) in Rathlin Island, Northern Ireland. It was dark so unlike the photo you couldn't appreciate how deep you really were.

                                            Awesome experience, all the same. As a no stop diver I only had a few minutes at that depth but it was quite a buzz. I am certified with CFT which are the Irish branch of CMAS although I started out with PADI.

                                            PADI is the only one which is in the English language. It stands for Professional Association of Diving Instructors. It is a very common scuba diving certification around the world.

                                            CMAS (Confédération Mondiale des Activités Subaquatiques) is the world’s first international diver training organization and was founded January 1959 in Monaco by a confederation of fifteen countries, including the United States, to establish an international diver-training standard. Organized under the direction of Jacques-Yves Cousteau the co-founder of the “Aqualung” and father of the modern sport of scuba diving CMAS has grown to a membership of over one hundred countries.

                                            CFT stands for "Comhairle Fó-Thuinn" which is Irish (language) for "Irish Underwater Council". We get our authority via CMAS. Diving clubs issue certification according to the rules and regulation of CFT and we train our own people to dive and become instructors, rescue divers, etc.

                                                To put this in reference, the deepest constant weight freedive is 125 M (407) feet and the deepest no-limits dive is 214 M (702 ft)

                                                  That filled me with a certain sense of fear that I had never even felt before.

                                                  Would it make you feel better to know it's not 100% real? It's an awesome short film, but it is a work of fiction (the description under the video makes this clear, but lots of people don't read those.) It was edited pretty heavily and he didn't actually hold his breath the entire time because that would be impossible at that depth for that length of time.

                                                  As a recreational SCUBA diver I can say that the REAL parts of this film are super awesome and required some serious talent, but it wasn't quite as scary or dangerous as it looks.

                                                    I don't think he'd be awfully happy to cut his balls off in an emergency. Nor would he be able to cut through the steel!

                                                          The uniflippers seem oddly inefficient for human physique. Am I simply ignorant? It seemed a great many of the divers enjoyed them.

                                                          well swimming also seems oddly inefficient for our physique, but people seem to make it work.

                                                          Swimming is really inefficient. The question is really more of why they would choose the uniflipper (which is more expensive, AFAIK) over two flippers if it's less efficient. Or is it?

Unless that whole thing only applies in the ocean. Like I said I'm no expert.

                                                                    [–]Guy_Dudebro 75 points76 points ago

At 108 ft, it's at ~61 psia; then down to 14 and some change at the surface (or 47 psig down to zero; thanks Dogmeat). That'd suck.

                                                                    [–]Realworld 53 points54 points ago

                                                                    You can comfortable ascend to the surface without new air. As you go up, the air in your lungs expands. As Guy_Dudebro said; you actually need to continually blowing out a small stream of bubbles all the way up, to keep from rupturing your lungs from relative over-pressure.

                                                                    [–]Guy_Dudebro 26 points27 points ago

I'd imagine at that depth, they'd feel like a million bucks as all that oxygen is squeezed into their bloodstream and goes to their brain.

                                                                    Problem is, on the way up it rapidly goes back into their lungs and they have to worry about passing out before they reach the surface. You'll notice they have a buddy come to meet them to make sure they stay conscious.

                                                                    [–]failedexile 34 points35 points ago

                                                                            Certified Diver here. They teach us in training that when surfacing from depth, you slowly let air out of your lungs as they expand from the pressure drop. You essentially let out a small continuous stream of bubbles as you come upward. In short, ruptured lungs are not a problem if you know what you're doing.

                                                                            The larger problem with quickly rising from depth is the possibility of nitrogen bubbles forming in your bloodstream as the pressure drops. It can result in "The Bends" where nitrogen bubbles get lodged in your joints and cause immense pain, sometimes crippling people for life.

                                                                            [–]cyburai 16 points17 points ago

As someone who survived a 90ft ascent after a catastrophic equipment failure and a moron for a dive master (didn't give his octo reg to supplement my lack of air), I didn't walk away from it. But I did survive with minor injuries.

                                                                            After I relalized there would be no help from the dive master (who was the closest to me), I began my ascent on the air I had. While I made it to the top with out the bends or blown lung, I was hyperventilating and blue in the lips. Divers boat has no oxygen on board. They haul me to the beach where an ambulance takes me. I reoxy'd my blood over 2 days (two 5ft tall tanks), but avoided a hyperbaric stay.

                                                                            Oh, all this the day after my proposal to my wife. Any they stole my underwater camera. I might, I say MIGHT, still hold a bit of a grudge over this. But I doubt it. ;)

But at the time, I was trying to control the panic that was starting. I'm pretty buoyant anyhow, so I figured it would be better to take my own life in my hands and risk going topside.

                                                                            [–]flyingponytail 4 points5 points ago

A good dive buddy of mine did it from 70ft - his buddy was too far away. As long as you steadily exhale, I think that can be the right choice.

                                                                                The depth of an open water emergency surfacing training is supposed to be 30', I believe (If some open water instructor wants to correct this, feel free, it's going off memory|I updated it). The idea being you let the air escape your body as you ascend to avoid and air embolism. I'm sure people could do it from 108'.

                                                                                PERSONALLY, during cave training, I was given a simulated out of air half way through my breathing cycle just prior to inhaling. Longest 20-30' swim of my life. It was painful to be in a relatively tight area, with no air, finning as to not kick up silt, get the attention of my buddy, and get a working regulator.

                                                                                Edit:

                                                                                http://www.youtube.com/watch?v=xUlE4ZxfDfY some people freediving the pool.

                                                                                [–]GeorgeTheWild 2 points3 points ago

However, when we were in the pool, we did an out of air drill from the bottom of our 18' dive well at the University of Texas swim center. The dive instructors shut off our tanks and had us breath the line dry so you felt what it was like to run out of air. We then had to wait while they turned our tank back on before we began ascending again. It's certainly not an an experience I'm likely to forget but I'm glad it was part of the training to do it in a controlled environment.

                                                                                [–]failedexile 1 point2 points ago

It's something you want implanted so you don't say "HAHAHAHA, it's cool". It sucks. I'm pretty sure drowning would suck.

All submariners used to ascend its 30m depth from an escape trunk at the bottom until 2009. That's when they came up on the wrong side of a cost-benefit analysis.

If the free divers were to take a breath at the bottom of the pool it could be catastrophic i believe

Freedivers absolutely can and do sometimes get decompression sickness (aka the bends.) Advanced freedivers conducting repetitive deep dives for long periods underwater, with little recovery time at the surface have developed decompression sickness from an accumulation of nitrogen in the body. There have a lso been many instances of commercial freedivers (those making a living harvesting pearls, sponges, lobster, fish, etc.) doing breath-hold dives for several hours in a day, to depths of 60 to 90+ feet, for periods of two minutes or more per dive, have displayed signs and symptoms of decompression sickness.
