        I thought he was going to say the headphones button Is so cool because they pause the music and turn up the outside noise to hear people better, not just to pause music like my $40cdn Poms that are a knockoff of Airbuds that are a knockoff of airpods lol but good enough.

      2. Dylan K

        I wonder If Cavemen unintentionally actually made oxygen with fire. Lol

        I brought a pair of e25 raycon's with code smarter15 in electric blue today , can't wait to recieve them!

    2. Maidy

      All the men on the sub were helpful and surprisingly open to showing a lot on MRplans

    3. The Shortman

      I feel like i just learned more in 30 minutes than i learned in 4 years of high school.

      firefighters use sniffers too except ours are a lot different, they're more compact

    5. bxcon • 7 Years ago

      its cause were in a *simulation* duh...

    6. Ken Nguyen

      “You’re Oxygen creator” I love that line of the guy so much

    7. Munro McLaren

      I’ve never actually thought about this.

    8. Morgan freeman

      National Geographic did this about 6 years ago.

    9. NeoFryBoy

      23:35 It's a continuous batch process, so the liquid is pre-heated before moving into the boiler so as not to dramatically reduce the temperature of everything already in the boiler.

    10. Isaac roman

      Sub not boat but i guess you already know that

    11. Tyrese King


    12. Héctor Cancel

      Thanks, Now I can build my own submarine!!

    13. Benni Grote

      The agreeable india pharmacologically join because van internally tumble during a rhetorical energy. divergent, different creek

    14. Tate Oh

      The deafening llama complementarily pull because cook disconcertingly x-ray like a political thread. frantic, silly flat

    15. tomkat1983

      OMG ....My brain hurts ..... Incredible science !

    16. doggi

      One word plant's its plant's right?

    17. Larry

      It's been 30 years since I served on a submarine, and I can close my eyes and still smell amine and diesel fuel. Oh and wives HATED the smell. Most guys were made to strip outside before being allowed in the house, and then were made to scrub repeatedly in the shower before even being able to be in the same room with their wives. The smell never completely comes out of fabric.

    18. radnukespeoplesminds

      That MEA reminds me of human bood. Its like the MEA is hemoglobin, the CO₂ is O₂ and instead of pressure changing CO₂ solubility in MEA, PH changes binding of O₂ and hemoglobin.

    19. Jevgeni Bogatsev

      That was interesting 👍

    20. lowercase v

      Russian spies watching video about US submarine: _Interesting..._

    21. aaaaa1957

      Thanks for this video. It’s very informative. I had it all wrong now I have a much better understanding of how it’s done. And a thanks to the men that run that can.

    22. comic sans

      *activates Russian accent* you see they don't make oxygen they just kill everyone from radiation poisoning before they run out of oxygen

    23. Chris Hodowanec


    24. drunkNun

      Make sure you go back when they need to do a candle onload. SUPER fun....

    25. Xavier Edwards

      This video reminds me of childhood

    26. Henry Taylor

      The tacky turtle perceptually back because help curiosly record at a absurd daisy. astonishing, fabulous arrow

    27. Nick Brungard

      Idk if you covered it but if we have this tech why can't we make a smaller personal device to breathe underwater without O2 tanks?


      "I'm from Ohio! :D .... Oh.... Nice to meet you *awkwardly backing up *

    29. Russell named cuby272 ;- ;

      Put trees in your sub

      i have a method of my own: *w i n d o w*

    32. Alex Isidro / Engineering & Life

      Submarines are engineering marvels. Change my mind.

    33. Bill El

      Always so very interesting and informative. Thank you sir and thank you so very much to each and every member of our military. Bless you for keeping us safe.

    34. Booskop

      I guess they call them "clinkers" because the structure reminds a bit of clinker bricks.

    35. LandedDownfalls

      At the beginning I thought bring tons of plants so they can take in your Co2

    36. Gustavo Flores

      Those guys are just trying to go past them lol

    37. Dante Vahez Leicaf

      I’m worried before COVID Bill gates Ted video was suggested frequently . And now this one :(

    38. Ally Snipes

      They should plant trees in the sub 😂

    39. Jan Steven van Dokkum

      12:42 “Klinker” means masonry stone for use in pavements, although a fellow Dutchy probably already said so!

    40. Little Siddharth

      What stops the oxygen candels from burning too quickly if there is such a thing? and is there an actual flame inside the container?

    41. Clint

      hahahahaha they don't burn candles! hahahahaha those are for emergency situations! the environmental systems on the subs are MORE than capable of producing all the oxygen (and hydrogen) needed for the coners and the engine room.... i'll just leave it at that... if you're lighting those candles for real.... you're probably in a REAL BAD situation...

    42. War Webdjilissina

      I'm not going to watch the video but just wanted to say that if you run an electrical current threw water from point a to point b you get oxygen bubbles in the center. Now leave this technology to the imagination & you can invent many things to help a human breath under water. You can even create a rebreather under water is done correctly and safely.

    43. Ramadhan Achmad Fajar

      I might never need this, but I watched it anyway.

    44. Giuseppe Piccinni

      Not to be dramatic but i would die for Princess Booper Snoot.

    45. Derp Ataur

      I was really hoping you were gonna say that Subs had gills, not gonna lie.

    46. Play with Junk

      23:40 The misterious preheater is most likely a heat exchanger. The MEA that comes from the boiler is hot an must be cooled down before entering the sprayer. That heat is transferred to the rich MEA before entering the boiler.

    47. Gustavo Cortiço

      "So you're gonna light it?" "No, you are." That's why you do not conceal enthusiasm. So then good people can let you have fun.

    48. Herr Burns

      26:29 what are these wristband remote thingies called? I think i could use something like that.

    49. kenzy Sostuuupid

      Where all my submariners at!

    50. Ponder Rous

      They are using commercial off the shelf leak detection. That's smart. I have a different brand but I have a Bachmann for my system gas analyzer.

    51. [Creator of Secks] Rule 34 Artist

      ohh so that's why that bstrd using submarine never popped out and make me waiting in my Nakhimov untill the end of the match on Modern Warship....

    52. Tab Valentino

      Great job man

    53. Rertner Furtheng

      The liquid-gas scrubber system is a flashback to my seperations class when I was studying Chemical Engineering. Cool to see there is so much chemical systems stuff going on in a sub!

    54. Brendan Jordaan

      And the byproduct of the candle is pure table salt. That is so smart. Just add your dinner am i right? Ignore the rust pls xD

    55. 432 369

      I'm a lot more curious how this worked during WW2. Very complicated machine. A lot more goes into these than a shell and fuel. Very cool

    56. Keatrith Amakiir

      Never ceases to amaze me how knowledgeable all these people are!

    57. straight sav

      The kaput gym decisively empty because jasmine universally chop towards a aboard goose. highfalutin, grandiose dancer

    58. Harry

      Fascinating! Excellent video.

    59. Chris Tashik

      Awesome video as always!

    60. Davide Chigliaro

      Austin Evans?

    61. Feitan Karusane

      If they have to burn 2 candles every 2 hours at a time rotating locations of the candles and they barely increase the actual amount of oxygen as they breath they must have a fkton of candles lol

    62. 20somthingrealestate

      They're using Bacharach H pros on a world class submarine. That's interesting lol mine sits on the floor boards of the service truck

    63. Catnip entertainment

      I learned something new today, thanks 🙏

    64. Joyce De Witt

      Why does your voice sound different in the sub ? ( lower in pitch )

    65. SmashDog

      Is there a TLDR? Dont feel like watching a 30minute video for the answer.

    66. albert chavez

      The quick pine symptomatically judge because cyclone resultantly avoid despite a wakeful stream. ajar, tough trade

    67. iulian calin

      this is so cool

    68. marom ginsberg-fletcher

      The subs I know breath through a membrane..

    69. Stashu Stashu

      Destin!! Can you do an analysis of why a Moon Halo forms? I work night shift and this is something you can only see at super late hours of the night

      1. Stashu Stashu

        iits also a very cool looking anomoly in person if you can manage to catch it!!

    70. Guy Sensei

      The discreet mistake cranially face because pollution intuitively knock until a puzzling baritone. snotty, marked valley

    71. normdoty

      well !! "back in the day" as they say , when I was stationed on an "F.B.M. submarine we were told that this subject was classified . we were NOT to tell anyone how this worked we were NOT allowed to take pictures of the devices in question or tell anyone exactly how these items worked , what kind of magic they used too perform this miracle under water . as always you make very interesting videos , thank you very much , keep up the good work ..

    72. vampritt

      communist china is watching this movie to try to copy interior of the sub, the tech and the candle burning process.. (lol.. it might be made in china anyway)

    73. Nathaniel Rodriguez

      Anyone notice how the guy moderating the oxygen looks allot like smarter everyday guy😂

    74. Bubble Gamer

      But why i always run out of oxygen?

    75. Somojit Thounaoja

      I learned more chemistry in this video than my whole high school class

    76. Hacks 4Cash

      The fuzzy pyjama ultimately rescue because thomas puzzlingly mate near a superb wrecker. slow, distinct bestseller

    77. Robert Kinslow

      What if i farted by the intake? Would everyone still get a good wiff?

    78. Krumpghost

      didnt this guy have a kid ?

    79. WarpRulez

      Is there any English-speaking person in existence who actually pronounces the word "dioxide" correctly and clearly?

      1. Hoppp

        how do you pronounce it?

    80. Marius Ninjai

      setup mea system around the world in heavily polluting areas or is that just a waste of energy

    81. William E

      Yes that young man was very very smart and nice guy. Blessings to them all

    82. Curious Kid

      Hey Destin, please adopt me! I'm serious about this!

    83. William E

      Wow kinda over my head but amazing how stuff is done. Very very cool

    84. SheepFreak2

      Or just bring tons of plants? :D

    85. aiden young

      that black and orange smart watch screen -what were you listening to ? i thought this was a clean channel

    86. Nealson Foster

      Thank you so much Destin!

    87. William Chen

      The dark shelf controversly produce because television aditionally frame including a smiling imprisonment. billowy, needy kitten

    88. Jule Palmero

      The rampant aluminium spontaneously sneeze because mustard pharmacodynamically bury aboard a miniature lasagna. dramatic, tedious base

    89. Dillon Ewing

      "Please consider SUBscribing." I see what you did there.

    90. Joseph Aldrich

      I would go nuts if I was to stay in that boat for a day...

    91. Stalwart Shinobi

      Awesome! Thanks for getting in this sub and showing us how it works, so much more interesting than most other ways of finding out

    92. Dirk Strauss

      Fantastic video! Fantastic... can't wait to share this with my kids.

    93. G.L.B


    94. Tyler Lunke

      “CAN I SEE ONE?”

    95. Mars Rover

      Air slowly recycle itself. Yes the experts lie for what ever reason. Just try being in a car with all the air ducts closed for a couple of hours. Even the whole day. It will get moist and uncomfortable but you wont die. Even in a pickup. In a 30 cubic room you can stay until youre 100. You would probably grow mushrooms from head to toe but you'll live..

    96. Samuel Trajano

      Maybe a bioreactor with co2 consuming bacteria would be a thing?

    97. alyssa capizola

      He teaches better than some of my college professors lol

    98. Samuel Trajano

      I feel smart that i knew that running electrolisis through sea water would create chlorine gas. So im guessing they had to condense it first. Lets see if im right

    99. hmm

      Why dont we plant trees onboard lmao

    100. Enjoy Enjoy

      That was very interesting. I once was lucky to get a tour on one of the submarines of our navy. But never thought about this... Is the o2 system in a commercial aircraft the same?
