I explore the world using science. That's pretty much all there is to it. Watch 2 videos. If you learn something AWESOME, please subscribe if you feel like I earned it.

Contact: I currently get lots of correspondence so please forgive me if I'm unable to reply. I mean well, but want to focus on being a better Dad.

  • 1:45 when the impostor is sus

  • Which camera do u use bro for slomo

  • So freaking cool do more do more PLEASE!

  • is 15:04 where nine inch nails got the band name :p

  • I’m commenting to increase interaction fir this video

  • Me: many tree

  • Off topic but you want this, here is a possible suppressed free energy idea, the stirling engine, using the same flame you can increase the torque to get more power without more flame, you do it all the time on your tires, you add pressure, do the same on a stirling engine, increase atmosphere pressure and you get more torque with out adding more fuel, it s easy, go as high as your metal allows psi pressure.

  • I bet the mess hall never serves beans on that boat while the buckeye is burning those candles.

  • Preheating of the MEA is mostly likely a heat recycle, where the hot lean MEA is used to heat the rich MEA in some heat exchanger. This also effiecently cools the lean MEA, which increase its ability to absorb CO2 since cooler liquids have greater gas solubility.

  • After that tank hit by a missile, I was expecting loud ear ringing noise effect:D

  • When I read the title, I thought they were using electrolysis to get oxygen and just pump out the co2

  • What about Methane?..........human farts.

  • 26:47 best part of the video 😍😍😍😍😍

  • Saying Gif is .. child first saying Muma .

  • Before anyone says "We should just use CO2 scrubbers to reverse climate change" - CO2 scrubbers takes a LOT of electricity to run. Also, you are just capturing the CO2, not getting rid of it.

  • Imagine playing Pokemon Go with that.

  • I always like the way you explain stuff.....your facial expressions are really good!!

  • why would you say no to aviator sunglasses in that situation????

  • The plant environment contrarily try because lamb postoperatively whistle a a deep penalty. symptomatic, energetic step-sister

  • 5:24 *SHINEI KAKYOIN!*

  • Snatch blocks? I thought this was a video about NBA 2k21

  • The smart apartment distally water because leaf essentially battle down a guttural H habitual bass. hulking, damaged hamster

  • They just roll down their windows..duh

  • I did electrolysis for a science fair project (testing the effects salt had on speed) and decided to take a sniff of the "oxygen" side, during a run with saltwater. Didn't even clue into the fact that since the house smelled like a pool something might be up. 😬 Glad I had the sense to step outside immediately into the fresh air as my airways drastically restricted! Needless to say, I stopped experimenting for the day!

  • You are like Phil Coulson to me.❤️👍👍

  • Linus a million dollar worth company CEO and never feels disrespect sitting on floor What a man 👍❤️

  • As a retired U.S. Navy anti-submarine and multi-sensor specialist, I can assure you that all our nuclear subs CAN break through the ice to "get fresh air". Mainly they must have this capability to launch ballistic and guided missiles. They also have the ability to release "sensors/transmitters/receivers" that can break through the ice when necessary. The technology on our newest boats is mind blowing indeed. Just wait until you see the 6th gen fighters and bombers!

  • what about the weight of the pulley system at the bottom ? the more the heavier... but it could be insignificant to the weight being moved

  • How the liberal mind works was summarize most eloquently by Ronald Reagan. It's not that are liberal friends are ignorant it's just that they know so many things that are just not so.

  • I am surprised that electrolysis is fast enough to be practical for something like this.

  • How fast would an iron bullet go in this canon?

  • He is just showing of the creations of other

  • 9:36 to your left the smoothest guy in the crew

  • One can also use Calcium hydroxide a.k.a. slaked lime to absorb CO2. The products of the reaction are Calcium carbonate and a pure water.

  • That's a nice Vulcan rocket. 🤣 See what I did there? 🖖

  • Answered my question why subs don't ping all the time like the Seaview on "Voyage to the Bottom of the Sea." Great soundtrack for a TV show but not practical to broadcast "here we are, here we are, here we are, ..."

  • Oh I get to learn of the sn774 I have a toy if it

  • So I'm not that smart 🤔 but what I'm hearing is even though you said many times "light a candle," you mean not just ANY old candle but a special candle that isn't manufactured for public use?

  • O2 partial pressure of 153 torr is normal where I am, but obviously the ambient pressure on the sub is higher so you'd be aiming for what? 160 torr? 200 torr would be a fire hazard.

  • So my question now is: When Destin get's home and gets on the backwards bike, is it the normal way to ride a bike that means he can't ride the backwards bike, or is it the backwards way and he can't ride a normal bike. I'm intrigued to know.

  • “Then you have a leak” hahahahahaha yeah not a problem

  • Destin, I have a friend who has an LLTV sitting in his shed at work. I was fortunate enough to get a tour of his "work" and I can honestly say as much fun as it looks... yeah, no... His work is the same AFRC mentioned in your video. I was most impressed by the Peroxide thrusters mounted on every corner and axis of the unit. A tour of the Armstrong facility was the most incredible thing I have had the opportunity to experience. if you are ever there ask about the LLTV and perhaps they can take you to the closet for a look see. God Bless you man, I love your take on science.

  • My dog is cuter than yours. Jk cute puppers 😂

  • I work on this stuff for a living, developing and testing. Very cool video, well explaining the basics, showing stuff that a lot of people never knew.

  • What do you do with the leftover Chlorine? Do you have leftover Chlorine?

  • Lol easy, just bring some enough small trees and bushes they make oxygen 😎😎

  • My first 2 seconds thinking: Oh, that's really simple Next 2 minutes of thinking: Okay, there are a million problems I can't answer

  • If we paid only half the attention to our teachers as we pay to this guy we'd probably all be A students.

  • this is bs... the nuclear reaction with sea water creates oxygen...

  • 3:00 I was expecting to see the ammunition levels in the UA 571-C Remote Sentry Weapons System :)

  • I'm guessing the cut after Linus mentioned the quantum computer was probably to remove 30 mins of pure nerding out.

  • We aren’t going back to the moon, not with lunchbox Joe in power.

  • The amount of times he asked “Can you show me” makes it sound like he’s a spy, lol. But so glad they did though. I learned a lot 🙂

  • Don't watch the whole video! In Submarines they have a machine who gets the Oxigen out of water! (H2O) End of video!

    • @zuygj bnsv No, it's not! There never will be an enemy or a spy inside a submarine!

    • Basically, a sub is Among Us irl.

  • What about the nitrogen component that's what we mainly breath.

  • I was on the 705. Its amazing that nothing much has changed since I left back in 96.

  • Right now ALL of the yardbirds are WTF CAMERAS?! NOOOOOOOOO!

  • With the new Mars rover having the MOXIE to create oxygen from CO2 - if we have the means / science to convert CO2 to Oxygen and have power from Nuclear Reactor of Sub why would they not use a MOXIE to take CO2 and remake Oxygen without having to use these candles.

  • Our AEOG was also always down. Thank God for O2 candles!

  • Captain Sean Connery is watching everyone on the sub

  • It's like watching a grown 8 year old...

  • Welcome to the US military. I am sure my phone has 100 times more memory than the CAMs system on this $1.5 billion

    • But then its probably as robust and reliable asf ... no viruses or hackers

  • 5


  • I freakin love military science.

  • "That's a Class D fire. We can't put those out." That's a pretty good reason to keep the lid closed :)

  • crazy vids !!!!

  • "that is a very bad thing and it would kill people" but kaaaaarl xD

  • Very interesting

  • Wow! Great video! I think the military is going to be giving you guys a call

  • I love the Alabama accent

  • how did u managed to get there?!?! how???

  • When I saw the thumbnail I thought the guy on the thumbnail was joel kinnaman 😶

  • Obamium

  • I always wondered why the crews of subs in films feared seawater getting to touch the batteries . I learned something today .

  • I truly appreciate how he makes sure it's understood all people who make this happen, not just pilots are Heroes.

  • Nice painting skills right there, appreciate it

  • Linus didn't drop that thing?

  • I love your videos Destin, but I am put off a bit at the more recent military-centric episodes.

  • Basically, a sub is Among Us irl.
