        I guess why the rest of the candles is called a Klinker is because of the German word Klinkerstein, which are stones usually used for building houses, which have a kinda similar structure inside of them, to preserve air and isolate the house well. Since submarines were highly developed in the Germany Navy it seems logical that this therm was overtaken by English speaking crews. YAW.

      5. Daye Jung

        Dustin, it would be cool if you talked about sonic booms underwater.

    2. Rueben Didit Fidget

      Is this not a security breech of navy intelligence?

    3. Yasu Leone

      Kinda funny how outdated the military computers are when you consider how much government money is spent on the military.

    4. 0MoTheG

      Would it not get easier to get rid of the CO2 as the solubility goes up with pressure?

    5. Ken Haley

      As usual, an absolutely awesome video--I learned so much! Thanks for all the effort you put into making these educational gems. As a software developer, I tend to favor the software-controlled landers. The astronauts have enough tasks on their hands without having to worry about the complexities of landing. What if the software/hardware fails? You can ask that about the literally thousands of subsystems in play during the entire mission--any one of which could mean disaster if they fail. The answer lies in thorough testing and failover backup systems. Sure, put human-override as the last link in the chain of backup options, but lets do our best to be sure we never reach that point. Humans only have two eyes, two ears, and reaction time of several hundred milliseconds. Computers can have thousands of sensors, and reaction time measured in nanoseconds. And they don't get hungry, thirsty, tired, or distracted.

      What about nitrogen

      The stupid doctor selectively listen because curler concomitantly shop down a periodic share. pointless, unwieldy flower

    8. abrahameby fugui

      This dude wants to see everything. Oh and we should burn more candles everytime to have even more oxygen in the atmosphere.


      On a submarine or in a submarine? 🤔

    10. No LB

      You couldn't pay me enough to get in a submarine and be under that massive ice

    11. Fenborg Mathias

      Hey Destin! Ever thought of doing a compilation video with Taofladermaus? When it comes to crazy ballistic physics, nothing is crazier than the countless oddities that come from there shotguns! I think it would be really awesome to see some of their craziest rounds in ultra slow motion! Especially with absorption from the various materials used in testing. There's a lot of real potential to check there!

    13. Andrew Hobbs

      Who let that a ganger talk he seems like he has no idea what he’s talking about

    14. Matt Black

      So how do you make Nitrogen? Kinda need around 70% nitrogen and 20.8% oxygen in every breath.

    15. Isaac Woo

      ok wellllllllll what about space

    17. stellarfirefly

      Why would you not just keep the sniffer always set to detect "small" leaks? It seems like that setting would also detect large ones.

      1. wmopp

        "small" setting may show false positives

      Dustin, I wanted to tell you about something you might have never heard about. Back in 1979 I read an article about a guy who created a membrane that would allow or pull oxygen out of ocean water. Its made of plastic with red blood cells mixed in with the plastic. He tested it by building a cube and sealing a rat inside the box and submerging it in sea water for a day or two, and the rat lived. I think the guy was a scientist in Israel, but I'm not sure of this. I think I read this in Popular Science. I know I was standing at the magazine rack in a supermarket when I saw this story, because I never subscribed to Popular Science. Then again it might have been in Scientific American. The article went on to say that the Navy was interested in his invention. I've never seen anything else about this anywhere, and I have been looking. Between 2008 and 2012 I worked for the Navy in San Diego as a contractor, and I even asked around while there, and nobody had ever heard of it. So I don't know if it was really a working thing. It could have been and it just went dark. I would love to know if it would really work. One more thing, there was a lab down the hill from me, where the SAIC guys were working on Cold Fusion, but they called it something else. And they got results and it was posted on USfilm. Then they shut down the project. Our tax dollars at work.

    23. lmw lmw

      Yeahp, smarter every day...and learning from the best, US Navy. Awesome.

    24. RB

      Why is there iron in the candle? Thanks

    32. Jonathan Friesen

      Are not gonna talk about that guy's haircut at 12:17 ? That looks manly compared to alot of goofy silly hairstyle nowadays 😜

    33. dlj rocket

      All very interestig and informative. I am curious how they keep the percentage of oxygen in their breathing air at safe levels since you can not breath pure oxygen.

      1. Eddie J. G.

        They don’t evacuate the submarine’s atmosphere before they submerge. The nitrogen remains as it isn’t consumed.

    34. random269

      Wish he could talk like a normal person.....

    35. Rafael Guillen

      Since the air we breath is ~79.2% nitrogen and 20.8% oxygen, in a sub does the Nitrogen levels remain the same? and if it doesn't, how is it made up to keep the same ratio?

      1. Eddie J. G.

        The nitrogen isn’t consumed. It just stays.

    36. The Murph77

    39. Rainbow Squash

      Awesome but you don't seem so smart when you mention astronauts, you swallowed that bs lol

    40. WypmanGames

      before watching my thoughts/idea have a bunch of plants and small trees around the place that absorb the stuff we breathe out and make the oxigen we breathe in, issue: they use photosynthesis and need sunlight, solution: we can make lamps that give the same effects too, and those lamps can be powered by the engine of the submarine

      1. WypmanGames

        @Eddie J. G. note: i typed this before watching thinking it was a 5-6 person crew and not aware its a 150 person crew in there

      2. Eddie J. G.

        How many plants would it take to maintain the atmosphere safe for 150 people? How much fresh water would be needed to maintain the plants?

    41. Enila5

      19:41 father and son

    42. Juan Gabriel Falcon

      Why is the need of scrubbing the CO2? Shouldn't be enough to add the oxygen? (I don't understand why is more CO2 released in the air)

      1. Eddie J. G.

        We exhale CO2... as in, our bodies produce CO2 as a byproduct of metabolism. We’re constantly making CO2.

    43. Klipk

      "So is this you job" LOL

    44. J Steensgaard

      Amazing video as always, but there's one thing i don't understand. Where does the Carbon come from?

      1. J Steensgaard

        @Eddie J. G. Alright cool. Thanks man

      2. Eddie J. G.

        @J Steensgaard yes... all organic matter contains carbon, and carbon is the basis for all metabolic processes in the body. We get more by eating it.

      3. J Steensgaard

        @Eddie J. G. But wouldn't that mean that the people are eventually 'emptied' of carbon? The people need to get the carbon into them somehow. Is that all through food?

      4. Eddie J. G.


    45. wabs05

      So interesting thank you! Will discuss this electrolysis method in my science class

    46. B Person

      Do they sing "happy birthday" when they light the candles?

    47. Andrew Murray

      All you need is a bit of greenery - plants produce oxygen and consume CO2 although....a bit hard without sunlight.

      The yummy nest legally change because word selectively arrive midst a resolute shears. somber, exciting exclusive russian

    53. Joe D

      This was an amazing video

    54. Fenrir Nobody

      When he said it was "self oxidizing", I realized it was a form of thermite reaction, where O2 was an output of the reaction, released into the atmosphere. Amazing.

    55. Sniperbuddy Dex

      i dont understand to it... so they are making oxy-hydrogen gas and separating hydrogen and breathable oxygen? because otherwise they could die due to poisoning from "browns gas" and i thought that this process of electrolysis is able to use only in welding technique or cars and not even thinked about it can be used as oxygen generator to submarines. nice video

      1. Eddie J. G.

        We purify water, then we use electrolysis to separate the oxygen from the hydrogen. We discharge the hydrogen overboard and store the oxygen or release the oxygen straight into the air.

    56. dsfgh zxc

      so... the mea doesn't scrub the carbon off of the co2... it actually takes the co2 out of the air

    57. rollonbc

      What happens to the co with the lithium hydroxide method?

      1. Eddie J. G.

        @rollonbc I don’t know much about rebreathers.

      2. rollonbc

        @Eddie J. G. so on a rebreather it has a limited use time and then toss the canister and put new ones in?

      3. Eddie J. G.

        The lithium hydroxide combines with the CO2 to become lithium carbonate and... just stays that way. We’d just throw it away.

    58. Silvia Fox

      Fun Fact: We are capable of scrubbing the CO2 out of this planet's atmosphere similarly to the way described in this video in amounts equal to or greater than what we produce. We have already built and used facilities to do such, with the largest currently being built in Texas. It is a 1 Megaton atmospheric CO2 plant, which is the equivalent of 14,000,000 trees in that one CO2 plant. It works great and we would only need 40,000 of those facilities across the world to capture all of the CO2 produced on Earth. Sadly all our anti-CO2 funding is going into monetarily inefficient "green ideas" hyped by the mainstream environmentalists funded by certain institutions focused on selfish goals which are not going to help the majority of our people prosper while keeping our environment healthy.

    59. Dalton Cloninger

      The Clinkers are named after an old blacksmithing term. When a blacksmith burns coal, some of the coal's impurities cant burn and are left behind, so you end up with a chunk of hard rock like materials in your forge. But when those chunks fall in your forge blowing fan they will "clink" around until settling or falling out.

    60. Jeffstan F

      Oxygen not included. Both way applied.

    61. Open your eyes

      4:40 the dude in the back lol

    62. Bryan Overton

      "We own practically 90% of the boat" I'm sure that TM div and M div totally agree with that statement.

    63. scubaseppy

      Could you burn this in your house in an emergency for heat?

    64. Tom Liu

      Destin when not filming: Haha I sabotaged your oxygen supply! See ya! ( is among us dead? )

    65. Nate

      Great, now I have the science I need to hide from other humans underwater indefinitely.

    69. Jason Garfitt

      This is a great video

    70. Trevor Johnston

      Is this... like... "legal?" I mean, isn't showing all this stuff kind of like revealing somewhat sensitive information, possibly harmful in the wrong hands? I mean.. shows where and how all the mechanisms for one of the most vital functions keeping our nation's service people *alive*... seems kind of sensitive,

    73. Michael Lederman

      About 40 years ago when I was a teen I bought an Oxygen Welding device from Sears which used a small version of those candles with a red substance on the tip, you'd light them just like you would a match and they burned at a phenomenal rate of heat.

    79. Daniel Curtis

      I could be wrong but I believe NaOH can work for scrubbing CO2. I always thought lithium hydroxide was used because it’s the lightest available hydroxide available. And on a boat or in space I hear weight is a bit of an issue...

    80. Dan Ostrom

      so what do they do with the salt (NaCl) that is left over from process?

      1. Eddie J. G.

        Out with the garbage.

      He's looks so young yet knows every little detail when questioned. Props to Dow from Ohio

    90. Darth Vaper

      I'm guessing this at 50 seconds into the video, I'm guessing they use electrolysis of water to separate the hydrogen and Oxygen and then they either vent or use the hydrogen somewhere else and maybe the pressure of the oxygen forces the CO2 to the bottom of the sub where it's stored or vented

      1. Ptao Tom

        Plug.. Hole😂😂😂

    95. Hazy Skies

      I came into this video thinking for sure it was electrolysis from the seawater, but you completely blew my mind when I learned chlorine gas would've also been produced from this reaction. Now I'm *very* interested to hear how they do it. Perhaps by somehow removing the carbon from the CO² to produce O²? Guess I'll find out... **Presses play again**

      1. Hazy Skies

        Oxygen producing candles... ... ... ... Nope, I got nothing. I'm speechless.

      2. Hazy Skies

        Oh, so it *is* still electrolysis, just after filtration... Well that's a little disappointing, oh well :/

    96. Riadul Islam

      Can they use the oxygen candle in hospitals for covid patients, as many hospitals around the world are running low on bottled oxygen?

    97. Alex Fox

      use the oxygen candle for deep diving!
