    "Please consider subscribing" That sounds so much nicer than the typical line <3

    The earsplitting vibraphone arthroscopically enjoy because mom admittedly crash absent a sturdy bongo. dreary, chubby foam

  3. BladeTheWatcher

    This is probably as much as WWII or early cold war submariners knew about sonar. Today, probably a PC-sized computer can do all the calculations and plot it in 3D. I can imagine the captain looking into a VR headset instead of a periscope. :)

    What a great guy !! Didn’t expect that. He’s just excited and proud of what he and his company are building as the guy asking the questions. I bet it’s not the first time he’s explained it either, but he’s still proud and excited about the process.

    The “murder” of George Floyd was only a watershed moment for the US in that a lot of people eyes were opened to the unwavering misinformation campaign being waged by the mainstream media.

  7. Agung SP

    Do some general or high rank officer announce that youre gonna make these videos? the crews are polite and helpful, good manner 👍

  8. Leon Moto

    I can't believe that this slow monitor is the way of monitoring the oxygen level on a submarine, but that's just me :D

  9. Ted Tedness

    BOAT? in the Navy, EVERYTHING is a ship or in this case a submarine.

  10. Robbie Goldman

    Thanks Destin, now i can finally build my own nuclear sub without worrying about oxygen, isn't that cool !

  11. We are not livestock

    "Our normal way of creating oxygen is down" hahaha very reassuring...

  12. iKoyyy

    The submarine serie is great but this video in particular was by far the best. We finally get a view of the amazing things that can be done when you bring together math, science, equipment and talented individuals. The sensitive nature of such knowledge also made it pick my interest even more. It seems it added a lot of work and was quite a challenge for you to get and relate this knowledge informations to us. Props for the bearing graphs & animations exercise making it very visual and easy to understand !

  13. Brian Erwin

    biggest takeaway, princess booper snoot is great

  14. Burnt Mcgurnt

    Fix your watch there Dow

    What happens to the hydrogen? Is it used or just pumped away?

    thanks so much for makin this video man n introducing me to this alien tech physics manipulation demonstration!

    From a former line cook that was very enjoyable! Looks like working a cramped diner

  27. Kevin SFS

    You should work with Mr. Beast, and basically make "How many gloves does it take to stop a Supersonic ball ", or slightly faster than that. It'll be cool 👍 Like if you agree, I legit want this to happen lol

  28. LadyLeasara

    12:45 "We call these Clinkers. Honestly I have no idea why we call them Clinkers" Clinker bricks are clay bricks that are too close to the heat source in the kiln. They come out overcooked, a darker color and usually misshapen and made a metallic ringing sound when you 'clinked' them together. They were rejects and discarded until their use was popularized during the Arts and Crafts architecture movement. Modern kilns are able distribute their heat more efficiently so they don't produce clinkers in the same way, but you can still buy bricks that are molded to give that misshapen and fire glazed look.

  29. All Espant

    Thanks bro. Am like touring insidr the sub 😁 what a nice

  30. Eric

    Off topic. How is the storage solution going? Floor full of loose drives again? Just watched the wholesome "160TB Server with Linus!" video again for pre pandemic nostalgia.

  41. Douglas county Kansas Railfan LKARFP

    Yeah but what if it was a toy gun maybe you guys should train it to look at the tip to make sure it’s orange

    Woah that's not a name you hear everyday that's a really cool name Dow, Dow Jones

    So cool!

  49. JaThe Winner

    I have two questions left from the torpedo video: 1. Where does the additional sea water that went into the second tank go? 2. Why do we give bullets a spin around their axis but not torpedos?

    1. Eddie J. G.

      1. Out the tube as it pushes out the torpedo. 2. Torpedos have control surfaces, navigate themselves and are self-propelled. They don’t need a spin to keep them straight any more than the submarine itself needs one.

    Oxygen stores, filters 'n scrubbers. Adios.

  52. Jez

    For the non native english speakers who struggle with the accents, the noise and the technical terms in this video, turn on the subtitles :)

  53. Nabman11

    That isn't Dow. I saw Austin Evans steal his uniform and sneak inside the submarine after he spent a week long bender smoking crack and playing MGS.

  54. MrFrosty Vlogs

    cant they use a thermal camera or temp camera to find the leaked pipes? that would be easier and fast

  55. Random Entertainment videos

    2 days later at school, how do you make oxygen in a submarine,,,,,,,,urinalysis

    you did the cool stuff dudeee,

  64. Jim Brohard

    excellent video - you made a complicated subject very understandable.

  65. Erbi Gimbi

    It's totally fascinating.

  66. Davy Jones

    Clinkers: a term from the coal burning boiler days when spend COAL ash had SLAG deposits that were called clinkers. The Clinkers were more of a solid mass then a powder ash.

  67. John Cook

    The fragile man biosynthetically object because increase erroneously bat save a steadfast blowgun. marvelous, deeply colt

  68. LynxEng

    They probably spend more time repairing that Xerox MultiFuntion Printer than they do repairing anything on the sub

  69. SSS Smile

    inlove you

  71. Octo Games

    Video Idea. Will you consider an episode on gold and off world mining and how mining elements off world would effect traditional market value and manufacturing?

  72. Josemanuel Piceno Vasquez

    Is it acceptable to call it a boat when it's a sub?

    1. Eddie J. G.

      Yes. Submarines are affectionately known as “boats”.

  73. Oli_Ing

    This guy meets so many ppl

    No beard net?

  75. DerAltruist

    I can't wrap my head around it, to me it looks like you're getting extra energy from nothing

  76. 1Maklak

    There are two pieces of physics to understand blocks and tackles: 1) Tension (force) on both sides of a block must be equal, otherwise it would equalize. 2) Since W = F * s (where W - work, F - force, s - distance), you can do the same work by trading force for distance. For example with one block attached to the thing you're pulling and one end of rope anchored, you're using half the force, but have to pull twice as much rope to move the thing the same distance.

  78. Viva Wö

    Why don't they simply use plants?

    1. Viva Wö

      Alright, that's a good point ;) I actually have no clue how much oxygen a plant produces. But at least, they'd look nicer 🌱

    2. Eddie J. G.

      How many plants do you think you’d need to make enough oxygen for 150 people? How much fresh water would they use up?

  79. Palitzonsky

    I would be amazed but i saw lars splitting an arrow coming towards him...

  80. Serial Chiller

    did u see that bass pro cup? i wont tell the time go look for it
