        What if it goes boom

      3. Daye Jung

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

        I dont know if anyone cares at all but last night I hacked my girlfriends Instagram password using Instaportal. Find it on google if you wanna try it

        PLANTS do both scrubing CO2 and making Oxygen. How many plants would it take to do the same job as these alternatives? How about a comparison video? I'm sure many other fans like me would like to know.

    2. 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?

    3. Alex Fox

      use the oxygen candle for deep diving!

    4. Alex Fox

      Devin keeps using all the oxygen!

    5. MrAnthism

      No windows? Not a job for me!!!

    6. Poop Smith

      Electrolysis would be my guess. Tons of surrounding water, tons of electricity because you have a reactor, and you're already using some for desalinization.

      You had all my respect until I saw your running outfit. Dude... :) lol

    9. Flowmasta Flam

      sure, sniff away.

    10. Marc C

      i feel like every crew is a scientist lol

    11. Leonidas

      Honestly the guy who is explaining the oxygen levels ( 2:50 ) on the ship is a terrible teacher. Why couldn’t an officer or even a nco explain this? Anyways, awesome video.

    12. j abe

      Plug.. Hole😂😂😂

    13. Jacob Ellinger

      this might be a weird question but do subs have procedures for bed bug infestations and also what preventative measures do they have in place?

    14. Nikola Stanisic

      - It can monitor our atmosphere, oxygen... - So it is in the middle of the boat? - y..yes *taking notes in russian*

    15. James Null

      So very informative!!! Thank you for posting this video. 🇺🇸

      Are you kidding ME! Princince is the best little Lab ever!

    17. Erik Thompson

      Destin... Huge fan.. love what you do, but I was concerned that you suggested sprinkling LiOH on the bunks. I'm not sure what form this LiOH is in, but it looks like pure LiOH is pretty toxic (3 out of 4 on the Health Hazard scale) along the lines of NaOH (Lye). Might be interesting to see what we could learn about how this danger is contained. Maybe "the professor" (Martyn Poliakoff) at Periodic Videos might have something to say.

    18. Nic Ferrier

      I've got a really cool idea for a video. I'll try to make it as short a possible. The idea is basically catching a snowflake turn from solid to liquid then to gas all in one slow motion shot. I believe you could do this by lowering the atmospheric pressure and increasing the heat inside vs outside. I believe I witnessed this and would love to recreate it and see it in detail.

    19. malcoperegrantus

      you should not feature so many things that are intended to kill people

    20. Bobby Bologna

      those oxygen candles are so neat, i had no idea

    21. Bobby Bologna

      8:09 and just like that I know "Reverse Osmosis" hahaha! Never heard Destin NOT want to explain something before, hilarious.

    22. Jeremiah Lim

      50 million uninsured Americans will use VXPASS smart phone app...BSV coin to track their vaccination on double dosage injection. This is first time crypto currency is employed to track uninsured patients who do not have health record documents. I already bought $100000 worth of BSV coin as the future technology to rule America..

      How i make my house cleaned as the submarine?

    26. some irish fella

      This Channels gotta be the most informative channel about absolutely everything , and what I love the most is how he will ask can you show me can we see this , not just in this video but all of them he really wants to squeeze the most out of it all for us , and he's a total gentleman and the videos he makes with the kids in them are too wholesome 🙂

    27. Kai Cao

      How to deal with the hydrogen when using electrolysis to make oxygen? Unlike CO2, hydrogen is hard to compress and much more dangerous.

    28. dale blue

      Besides jet fighters pilots sub crew must be another geek level. Awesome

    29. Sutha Sinnathurai

      The people in submarines knows how much trees are important for us

    30. sorin caldararu

      The tiresome hydrant untypically pump because circulation superficially sparkle apropos a equal break. momentous, raspy aunt

    31. Rik Vermeer

      This sounds sooooo much like the game "Oxygen not included" :D

    32. Rik Vermeer

      Congratulations on making it as far as getting on board of submarines!! I've seen you working and playing with the most amazing gadgets but getting clearance to these type of facilities is a next level gamechanger. And the credits go to you.

    33. Stephany Gallego

      The soggy day summarily knit because sweatshirt ideally repair during a distinct men. third, mere stove

    34. Sven Simonsen

      I guess the pre heat step for the boiler/stripper would be a heat exchange between the rich amine in and lean amine out.

    39. latex glove

      It's clearly not you in the sub, why are you lying ?

      1. Tim the 55th


    40. RoxyDzey

      you said they cant go up to take fresh air but they did to pick u up.. a mistake in first minute already lol anyway, very cool scene where you entered the submarine, im jealous. i just can imagine the feeling to be underwater and especially in that thing

    41. Navneet Singh

      look how calm they are while working.

    42. Mj Verostek

      Duh, trees. I don't even need to watch this video.

    43. Leo Cieri

      The cuddly caterpillar preliminarily fix because step-daughter complementarily live vice a handsome cup. aloof, brown february

    44. Nivar

      Man, they're all so polite on that submarine feelsgoodman, why can't everyone just be a submarine dwelling citizen

      1. James Word

        @Nivar completely agree. Even if people aren't entirely polite, but are always respectful then I'd be happy.

      2. Nivar

        @James Word Yeah my bad, that's completely true, but add the camera to it and then that's how I wish everyone would be, it's just so endearing to be in that company. It'd be nice if that'd be your daily interaction with people

      3. James Word

        That's on camera and XO is following.

    45. Pete OConnor

      A 9" nail huh? *head like a hole!!!!*

    46. Peter

      Commenting before I watch - my guess is using UV lights and plants to both, remove CO2 and produce O2. I'll see if I was right.

    47. Phiboo

      So if they produce Hydrogen as a waste product. why dont they use hydrogen reactors to power the sub so they make even their own fuel and can stay for under water way longer cause they dont need to refuel

    48. Chris

      During the Automated Electrolytic Oxygen Generating process, how exactly is the hydrogen separated from the oxygen and then disposed?

    49. Terd Ferguson

      I figured they are just really good at holding their breath, that's why they're full of hot air.

    50. ImagesByChaos Tee

      nuclear reactors do not create electricity, generators do. Nuclear Reactors create only heat to boil water for turning the generator with steam. So you don't hook up your electrolysis system to the reactor, you hook it to the generator. Just to clarify.


      Just one question *How do you get in a submarine??*

    52. Euan Hamilton

      Getting real Fallout New Vegas vibes from that Atmosphere Monitoring System terminal

    53. Daemon Spectre

      When the dude held the ignitor near the open and exposed candles. I cringed a little. Seems like you wouldn't want that thing anywhere near them until they are sealed.

      welcome to the navy. .mostly a bunch of nerds on a ship or sub....2001 2009 os2sw

    56. Tanaka Dingdong

      Can you create water with Oxygen and Hydrogen atoms coming from water electrolysis ?

    57. Ron Alexander

      Fantastic video , I learned a lot

    58. Nate

      It's all recycled farts, don't believe otherwise.

    59. Dorian-Mark Keating

      Liar ! No such thing as a Luna lander! U seem like a decent guy , but alas your a shill

    60. Christian Treber

      Why so many dislikes? Nothing exploding? Chemical formulas?

    61. Pyratebob1

      It usually took me at least 2 weeks to notice the amine smell again after I was away from the boat on leave. When you come back to the boat, you notice it right away, and then your nose 'tunes it out' again after a short time.

    62. Jake Hartsfield

      MM2 still rockin' the great lakes casio LMAO It's a great watch.

    63. Anonymous Blank

      water is made of two hydrogen and one oxygen molecule . submarines are under water . boom source of o2 . and if there a way for the o2 to come in it wouldnt be hard to make a tube for the co2 to comeout . boom done this is a joke btw

    64. David Murphy

      Half an hour to say "Magic"

    65. Nicolas Morita

      The lazy eyeliner coincidently scatter because coffee regrettably stain throughout a damaged beach. slow, guarded soccer

    66. Knightslayer111 ?!

      Guy in the back😬

    67. Cj Pizza


    68. Les Starck

      Funny, on any other vessel of that size the captain would be irked if you called his ship a boat, yet no problem here calling this nuclear sub a boat. Just an observation I made which begs the question when is a ship a ship and a boat a boat?

    69. Irvine Spiegel

      I'm not gonna lie. I thought they just had giant scuba tanks.

    70. Mister Smith

      Great vids as usual, thanks 27:27 the rocket moves.. 🤔 Is that normal.. 😂

    71. sffsd sfsf

      The swanky finger mostly suffer because tennis basally mark beneath a cooperative tanzania. imported, shallow creator

    72. Ryan T.A

      That *US FORCE AD* really does it as a COD commercial.

    73. Erik H

      Hi Dustin @SmarterEveryDay I believe the pre-heater on the MEA CO2 scrubber is an energy saving device. When the CO2 is compressed it increases in temperature. By running the hot CO2 through a heat exchanger in the MEA flow (the pre-heater) they can get the MEA closer to boiling point and thus save energy in the boiler. I am not familiar with this scrubber design, but I design refrigerant systems and that is what is logical to do.

    74. Mellow Yellow

      I love that you ask the questions. Questions I'd be curious to know and possibly think about asking.

    75. Mellow Yellow

      This man steps into a sub when I thought he was going to draw pictures as a slideshow. Instant Subscribe.

    76. Supper Slash

      I was wondering what software you guys use for your graphics. Like at 23:16 or at 8:10.

    77. Achiles Redemptia

      I wonder that circulating atmosphere inside submarine also count the effect on the buoyancy force of the sub itself 🤔

    78. Elliot Rowley

      "Awesome man. Where you from?" "I'm from Ohio". "Oh......................." Great video.

    79. Mija Oh

      That's the smallest nuclear submarine I have ever seen at the start. Technology is amazing. 21:19 Look how many pens that nerd is packing! I wonder if it's meant to be a joke.

      1. James Word

        My money is on he got yelled at too many times for not having a pen. You always have a pen. 2 pens in fact, just incase the first one fails.

      Destin! Visit SpaceX already!

    90. kenny ng

      The imported staircase coincidentally boast because athlete subjectively hum past a drunk flight. temporary, detailed ferry

    91. Creepyseven

      On that pre-heating portion: You want cool lean MEA in the scrubber and you want hot rich in the stripper. So you could either put a refrigerator or radiator behind the stripper and waste all the heat you put into the MEA or you can use a heat exchanger. With a heat exchanger you transfer the hear from the rich MEA you want to cool down into the lean MEA you want to heat up. This reduces the need to put additional energy into the system for heating and cooling.

    92. Josef

      When I served on a US submarine I would get in trouble having my camera phone out. So This is so weird seeing a video of a submarine.

    93. matata

      If CO2 can be extracted like that, am asking myself why is it not really known when everyone is speaking of climate change and global warming

      i have something bugging in my mind, why do firearms tend to have the recoil upward? why no downward recoil

      1. Jake Livni

        Hold the gun upside down and then which way is the recoil? Simple.
