        Thank you for the video, so interesting to me. Didn't know exactly how this worked, never actually thought about it. Amazing engineering.

      I thought that the sailors just held their breath😂

    6. kebman

      What happens if someone onboard a sub gets contageous influenza?

    7. Will Carter

      As a Submariner, the real limiting factor in how long a Nuclear submarine can stay submerged isn't oxygen, it isn't food or supplies, or even fuel. It's crew sanity. 😅

      19:05 - 19:40 the amount of awkward eye contact is uncomfortable

    15. Northern BC Fly Guy

      Are the methane or hydrogen sulfide concentrations ever a problem? Are meals designed to reduce flatulence?

    16. morvous1

      "A-Ganger, basically mechanics for 90% of the boat." Like the reactor doesn't take up almost 50% of the boat. Gotta show respect for the Nuclear mechanics too buddy.

    17. Taylor Morrison

      I feel like I should thank you, I've used information from no less than 2 of your deep dive videos to complete checkouts as I work towards my submarine warfare qualification. So, thank you Destin.

    18. ASMR Therapy

      Burn is not the right term. It should be called applying heat

    19. Joshing_you 7

      That guy is from West Jeff!!!!

    20. Wen-Wei Tseng

      Another chemical potassium superoxide could generate oxygen and scrub CO2 at the same time.

    21. Justin Franks

      It would have been way cooler if you used the ISS as an example. Everyone can understand the idea of a air purifier...

    22. Uyummi 5468

      Plant several plants in there?

    23. kushaditya

      austin evans side job is to work in submarine. Cool

    24. AmoriLinguae

      With the amount of CO2 in the atmosphere, I'm a bit surprised there were no allusions to why the CO2 removal technologies on a submarine are or are not similar to proposed/potential CO2 removal from the general atmosphere.

    25. Sovspot

      Oh man they use Bacharachs, that's like the worst brand of leak detectors.

    26. Moses

      I am very surprised that you were allowed to take a camera on the sub.

    27. Hazmania

      This Dow guy doesn’t like to explain his responses very much lmao


      This ain’t no ordinary sausage...

    29. James Coleman

      when the oxygen level suddenly dramatically raised.... houston we have a problem! everyone is dead lol

    30. Jack Sampson

      It’s crazy. Dustin likely knows more than these guys but you could never tell. Amazing

    31. Kagens

      I love stuff like this. My brain tends to ask wired questions. and this was one of them. Also, have you done an episode eon how solar panels work?

    32. brendan sweeney

      Not all Subs have reverse osmosis units, some have stills.

    35. Voidex

      Russia is very interested in such videos keep them going ;)

    36. Dynamite Dingo

      that Sub is as old as i am. it was commissioned on my birthday

    37. Ricardo Cazares

      Destin you need some portable lighting on your rig, brother.

    38. Anarchy Won

      This was very interesting. Great work.

    39. Mark Reynolds

      i'm so jealous of the toledo. im on the USS Ohio and i would've loved to meet destin. oh well. maybe i'll get that chance later.

    40. Workin Alday

      Nuclear Submarine "Deep Dive" ... I see what you did there 😏

    42. Alan Hazard

      Suck & Blow think they call them the Hilton sisters.

    43. Bright Soul

      subs are so scary im afraid of anything bad happening like that one russian sub that where a bomb blew up inside and killed a lot of the crew, then the survivors went to the back where it was safe; for now. and then a second explosion happend which killed more peeps. the only people who are alive by this point are a group of peeps who are in the very back part then, due to the oxygen generator breaking in the blast, they start running out of oxygen and it begins getting harder to breath them, being smart they tried to jumpstart the gen using some (some type of science tablet) but one of the peeps drops a couple into the salt water, making a third blast killing almost everyone. with the rest (injured surivures) they sufficate on carbon dioxide.

    44. Bright Soul

      entertain me dont make me think

    45. keegan davidson

      So the oxygen candles are essentially the same as the oxygen generators on passenger planes? Little less high tech than I thought but I guess less things to fail in a vital process.

    46. Uncle Ned

      I am insanely jealous of you. You got to start a class delta fire. In a submarine. On purpose. To help people breathe. That is so counter-intuitive yet so genius! I love every aspect of it!

    47. TeeJation

      2:02 "Where you from?" "I'm from Ohio" "Oh." :l

    48. Xander Original

      Thank you Destin, that was very interesting!


      2 of the 3 ways .. Very good.

      submarines 60 years ago didn't had this much technology dedicated to produce air alone oxygen, they were still using filtration systems from the late 40's if they had any, for oxygen I don't know what were they using.

    52. Takahashi

      Using plants Duhhh

    53. L C

      so if you are a cigarette smoker or a nicotine addict you can't work in a submarine.

    54. dog breath

      These guys remind me of my grandfather. He spoke slowly, and didn't use a lot of technical language, but inside he was incredibly intelligent and understood his job, and the world around him. He worked on an aircraft carrier for the US Navy in some job related to nuclear power (which he never gave any details on).

    55. Billy Stink

      Sometimes subs do run out of air, when good content creators leave us breathless.

    56. GeneralMills66

      Great Vid!

    57. Adam Parrish

      A submarine is a Claustrophobe's Nightmare.

    58. ALFREDO

      So, here is a challenge for you and probably for your other smart friend, the one who made the explosive baseball bat. What would happen if you get one of those huge fireworks that we see on the 4th of July and send it to the border of the atmosphere on one of those weather balloons and make it explode there. The real challenge is: how would you figure out how to film the explosion at enough distance to be able to appreciate the explosion and what would happen. Is there going to be enough oxygen for the thing to explode?

    59. Cl Arice Tayag

      The ugly reminder concretely radiate because bangle connolly sound like a sour internet. ruddy, scared bee

    60. Jolly Goodbeard

      This stuff is so I know and understand they had to view and remove any footage that you made for Clearance my question is did they keep any footage or delete anything you filmed or are you allowed to say??

    61. Viswas V

      Informative Video thanks 👍

    62. Jonathan Nocon

      Are these ‘candles’ available to civilians? ‘Tis fascinating... I wonder if they light a dud/bad candle, would that produce negative/harmful gasses instead. Who would have known burning can produce o2 hmmm... 🤔 Crazy stuff 🌈

    63. brxn

      I love this channel so much

    64. AG.

      Thanks for the informative video.

    65. Denzil Buchner

      These guys are playing Oxygen Not Included but in real life

    66. kwartylion

      2:52 Funny it even looks like it was taken out of a fallout

    67. ThatsNot Damxz

      Heat of absorption of CO2 and partial pressure of CO2 with aqueous solutions of MEA has been measured in a reaction calorimeter CPA122 at 40, 80, and 120 oC for 30 wt% MEA solution and at 120 oC for 10 and 70 wt % MEA solutions. Heat of absorption measured in this work is also differential in loading, i.e. CO2 has been added to the reactor in steps. An experimental set-up used by Kim and Svendsen (2007) has been used in this work after a small modification. Experiments show that heat of absorption depends both on loading and temperature, though the temperature dependency is not as high as was reported earlier.

    68. High King Trasher

      Well isn't that useful? An oxygen monitoring system that takes 2 minutes to get results. Seems like a weak point since it only takes 2 minutes to suffocate

    69. Isaac Howard

      Thanks Destin! Your questions are on point!

    70. Will Lowe

      According to my command, this is top secret information and this is treason!

      1. Cristian Londono


    71. Zoidberg227

      A subtle meta-analogy there between the oxygen candles and the reactor on the ship. The candles work by producing more oxygen than they consume, and the reactor works by producing more neutrons than it consumes.

    72. Krotan

      That dude is pretty cool, also looks like Dave Grohl. edit: Meant the guy with hat and glasses.

    73. ThatsNot Damxz

      This is Fire 🔥😏 Pun intended

    74. TDT Records

      I want to know how they keep the electrolysis electrodes from decomposition !!!!!

    75. Pyroon

      It's important to note that for each requirement, there is a power independent method of satisfying the requirement

    76. Hieki Nakamura

      whoa, i'm learning something new from this channel

    77. Richard Rejmer

      16:00 We don't want premature ignition, now - do we?

    78. A B

      I expected them using trees

    79. Richard Rejmer

      12:44 they are called "Clinkers" because in many industries the waste created if it is semi-solid and porous, it's called 'clinker'. e.g. the cement industry. For example, the ash formed by burning coal in a boiler will deposit 'clinker' ash or a glassy slag on the walls or surfaces of the boiler. Some bricks are also called 'clinker' bricks because of the porous appearance of them.

    80. Jim Dear

      4:34 and ill just head down here, uh nope nevermind

    81. Invigorous

      This series makes me feel like destin is plotting something malicious

    82. social3ngin33rin

      This episode is amazing :)

    83. Ben Ghist

      So if I remember correctly... carbon dioxide has 2 oxygen molecules... is there a way to separate the oxygen molecules from the carbon? Thereby creating breathable air from the waste air?

      1. Cristian Londono


    84. Daniel Walsh

      Given that the problem is too much CO_2, and not enough O_2, I’m surprised the solution doesn’t involve a chemical process that strips the carbon off of the CO_2, completing both the oxygen generation and carbon dioxide scrubbing at the same time.

    85. TwoStomach

      my house uses reverse osmosis

    86. Matthew Rhodes

      "you did this in 6th grade science or something like that" Unfortunately, I think we got the "something like that.." part...

    87. Andrew H

      Why not store liquid oxygen? Is it more efficient to ''store'' the oxygen in a solid state like the candle?

    88. Gavigu

      Yooo Dow was from west Jeff, it’s kinda sick I live there

    89. José Carlos S. A. Tissei

      people that work on submarines are so smart omg

    90. Kenny kohen

      16:15 imagine if the candle just decided to blow up that day

    91. skg901

      Can that good gas bad gas display detect who has a bad stomach...😂😂

    92. D B

      I spent 30+ days on a sub a long time ago and had no idea about the candles......thanks Destin for sharing this whole experience

    93. PelloTap

      The animations are extremely helpful for understanding the topic. Thank you for taking the time to make and include them.

    94. Mutantcy1992

    95. Mutantcy1992

      Always fun to watch Destin do some chemical engineering

      I appreciate that you did this, and explaining things to us. It’s too cramp for my liking
