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

  2. Oli_Ing

    This guy meets so many ppl

  3. TheSerGregor

    No beard net?

  4. DerAltruist

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

  5. 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.

    Why don't they simply use plants?

    Tomorrow is exactly one year from the release of this video do we have an update on how much lighter the vulcan panels are?

  11. DimljenaRiba

    Im happy I witnessed a time where actual humans were on submarines! So much science... *wow*

  12. Les Howard

    Twenty year old O rings holding back the vacuum of space and I can't even get the O ring on my best flashlight to hold back water in my sink after six months. Sounds like NASA has O rings as good as their 30 year old batteries that were made to last at the most 5 to 7 years in space but are by some miracle still working just fine after 30 years in the cameras that are taking better quality photos than they did 30 years ago at the far reaches of our solar system??? WOW NASA just has the best luck ? Am I the only one who see's a problem here????? Looking at the comments I guess I am! OK then have a good day all you Sheeple!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    Were you able to do this with Trump?

    Hes been using the same camera for 4 years

  17. Themagicphonebooth Q

    So technically a submarine can be in space?

  18. K_S Lyons

    I liked the part where they used a snatch block

    Raycon earbuds suck. Good marketing, terrible product.

  22. Musana Nice

    This so funny I couldnt grasp the concept

  23. TheRoyalPenguin

    Down Periscope is such a good movie, and it's absolutely hilarious

  24. Yaku Korku

    In a submarine or on a submarine?

  25. a z

    I wonder what would happens if supersonic baseball meets "Mad batter" machine

  26. Brainstorm Surge

    Reminds me of playing Oxygen Not Included.

  27. rondovk

    Unbelievably great video

  28. Gerard Ligonde

    The jazzy channel biomechanically nest because mistake chronologically rain worth a callous river. colossal, anxious sleep

  29. Eric He

    Subs=subscribers get oxygen by breathing

  30. Daniel Sánchez

    Nothing interesting in the comments, I saved you 5 minutes of bs.

  31. Razar Campbell

    Why does "Paisley" write her "g" backwards when it's the first letter of a word (grade, glass, good...) but she writes it correctly when it's at the end of a sentence (dog)? It looks a little bit like it was written by an adult who wanted to make it look like it was written by a child. Either that, or she should stop being home-schooled immediately and get a proper education...

  32. Who Farted

    How did they know the lunar gravitational force before going to the moon?

    By the way everyone whenever they say rocket factory they don’t make the whole thing they only make the shell and the stuff inside they don’t actually put in the controls the computers the engines or anything like that they just build in the shell and insulation as well as a few other things

  35. Maximilian S.

    Hey Destin! About a year ago I saw your post on /r/wien. In this video you're saying "Welcome to austria" at 2:48. Does that mean this is what you eventually ended up doing in Vienna or is this unrelated? Very little hope of getting this answered but still. Cheers mate 👌

  36. Douglas county Kansas Railfan LKARFP

    I wonder why they need to keep a rocket booster a secret

  37. Anything you want classic

    This , is how you hurt yourself 😑

  38. Michael Pritchard

    Why don't subs run out of oxygen? We don't.

  39. Hermitey Perez Triana


  40. WellAaron

    great now it made me want to play more oxygen not included

  41. Brandon Hsia

    The entertaining bus complimentarily lick because arrow substantively repeat including a internal pants. entertaining, early warm

    Awesome series

  43. Hunor Magyar

    sounds pretty corona proof air flows true the boat

  45. Brittany Levinson

    Unequivocally the best recruitment video I’ve ever seen. Had I seen this at 18, my life would have been vastly different.

  46. Lv.99 Mastermind

    Bruh just put gills on the sub

  50. illesizs

    How complicated would it be to electrolyse CO² into carbon and oxygen?

  51. blue03r6

    sometimes we don't talk back with command. sounds like it could be an intense movie. one half of the boat, we should launch the missiles. the other half, we should try to contact command again first.

  52. Dan Lo Fat

    Oh they're like the Galaxy 150 earbuds I'm kind of case same kind of charging yep

  53. Melissa8472

    really cool video!

  54. Google User

    West Jefferson, Ohio, right on

  55. Patrick

    Nice Miracle on Ice picture 2:43

  56. Dan Lo Fat

    Not only is an oxygen candle cool it's also super quiet so if they got to run silent it can still breathe for a long time

  57. Jacob Nations

    *shines light directly on his face*

  58. Brittany Levinson

    This is my favorite series of yours ever! Love seeing these men and women and what they do!

  59. Mohamed Amine Trigui

    The whole game was a hide and seek

  60. Roger Finch

    So, while we are talking "science", you do realize that you can't just "hook" up anything to a nuclear reactor to get electricity........right ? A reactor merely generates heat energy in a primary loop, which in turn heats up water in a secondary loop to form steam for a turbine generator which is what creates your electricity.

    What do they do for nitrogen add

    Eugene khutoryansky channel also posted a similar type of visualizing video

  64. Lil Chromosome

    You can tell Tory and Destin could be best friends. Destin is so excited to see all the stuff he’s dreamed of seeing, and Tory is super excited to nerd out with someone who appreciates and knows the magnitude of everything.

  65. James

    Drone needed to be overhead for the hits so it could follow the baseball

  66. KopaZ

    TLDR: 2 H2O = 2 H2 + O2 AKA electrolysis.

    i want to know how shooting that rifle made michael from vsauce feel. we didn’t even get to here his thoughts on the experience.

  70. Michael Spinelli

    Dow explains things about as well as submarines fly.

  71. Anton Belaschenko

    I am not used to seeing him with out the hat

  72. MacBulle

    Destin.. the only man on earth to call the US navy to ask for a vlog on one of their subs.. and get permission.

  73. darthryking

    So where does all the smoke get ventilated to after the fire's over?

  74. Neko Slacker

    It’s just a long tube like a snorkel

  75. blue03r6

    I remember the first time I rode a proper super bike motorcycle with 205 hp at the rear wheel, and the power it had on acceleration made me almost black out. 205 hp doesnt sound like a lot but it is for a bike that barely weighs 400lbs and a 190 lb rider. 0-60 on it is about 2.3 seconds. people are hitting 185 mph on these in 16 seconds from a standing start. i had never experienced such force before. it got kind of dangerous because I'm out on a public road. I only took it up to about 45 mph but I had to fight it to stay awake for a second after rolling off the throttle. now it doesn't even begin to bother me. kind of like what she is saying. you get used to it.

    They could use the hydrogen as a fuel source instead on dumping it. And fresh water. HHO gas (hydrogen) exhausts 100% pure water.
