@4-Methylaminorex this is incorrect the % of black neighbours doesn't decrease the value of a home. What the study you are referring to said was that areas of similar properties had a clear disproportionate price range, the homes and neighbouring properties in black communities were cheaper. Not that the same properties lost value as black neighbours moved into a majority white neighbourhood. What the study aimed to show was that black people were disproportionately affected. What they discovered was that black families were being more money savvy and buying cheaper properties and with a more family focused attitude with the only demand for housing being their descendants that created less demand. Where as white families moved to the city more often and city prices have always grown faster in price.this was in the USA . It's funny they only looked at certain areas. in the UK a similar thing was done but it was Asian communities that saw the boom in greater London

In the 90s I worked with a man in Scotland that served on a UK experimental submarine by peroxide, he told that the scientists on board used movie cameras to record the engine performance dials as the moved all over the place and were hard to to monitor.
I have to blame the loss of Kursk on "Russians", not "hydrogen peroxide". Those torpedoes were very old when placed aboard the Kursk; Russian sailors were scared to death of them, with good reason, and those torpedoes had been 'retired' decades before. But Russia never throws anything away, and somebody (no doubt seeking promotion) decided to try them again, in a big naval exercise the Soviets were about to start. They were "practice torpedoes" so they didn't get any special maintenance or thorough goings-over, they just filled the peroxide tanks and put them aboard Kursk. Thus it was, there was rust inside the torpedoes that nobody thought to look for or remove - and rust is one of peroxide's catalysts. There were further really stupid mistakes made; the Wikipedia article on the loss of Kursk is an eye-opener.
@@jrmckim No. Kursk admittedly, made many widows 😥 - but Kursk was K-141, an Oscar II class SSGN ( - "SS" = "submarine", "Guided" = it was built to shoot explosive guided missiles at ships, and "Nuclear" - ). The actual 'widowmaker', known to Russian sailors as "Hiroshima", was K-19, the first Hotel-class SSBN ( - only difference being the "B", meaning "Ballistic" = built to shoot thermonuclear ballistic missiles at enemy cities - ). K-19 had no official name BTW, as the Soviets didn't name their submarines back then, and was built a long time ago - it was commissioned in 1960, had so many problems that it wasn't used much, and was scrapped in 1991. K-141 "Kursk" was commissioned in 1994, was one of the last-built and most modern Oscar-II's, and after a horrific accident that blew off its nose and sank it, it was raised off the sea floor, towed back to Murmansk and broken up for scrap. Several Oscar-II class SSGN's are still in service with the Russian navy, but the Hotel's are all long-gone - and very, very happily, neither the Hotels nor the Oscar-II's (nor almost any other submarine in the world) ever fired a shot in anger. 😄
@dennisyoung4631 Quite a few nations used peroxide in their torpedos.But the russians were the ones who really embraced it to a large degree. One of these cooking off in the forward torpedo compartment is what killed the kursk back in the 2000s
@@dennisyoung4631the British tried it first, had similar results and swiftly retired them. The Russians embraced them, in typical contrary Russian style - deny a potential major issue until a somewhat expensive vessel and crew were lost. High test peroxide, makes a great mixer for scotch - if your goal is to make it to orbit quickly... If so, mix well, pour onto brass and enjoy the light and sound show.
Isn't that also why the Bismarck was sunk? The Royal Navy was in chase but had lost them, then Bismarck sent a lengthy radio message so the British fleet could triangulate the signal and sunk the ship.
@@urkraft3858 Yep. That was how the Royal Navy located the Bismarck, but that does not answer where the Bismarck was going then. IIRC, the Royal Navy originally calculated that the Bismarck was returning to Norway but they quickly realized that she was going to Brest.
The third weakness was that the wireless units were not yet able to be directional enough. Because of this, UK/US listening posts were able to intercept and decipher messages constantly.
Doenitz was keen to newer technologies, but grew up in the WW1 era navy and was slow to implement changes. The type 17 took resources and time away from the type 21 or just being so late on modifying the type 9's with snorkels.
Finally, for 50 years I have wondered about the details of the hydrogen peroxide submarine and why it went nowhere. Thank you Simon and the excellent team that supports you.
This didn't even mention its "best" features: Peroxide molecule is quite unstable and can decompose spontaneously releasing heat, which increases chance/rate of further decomposing. So if tank can't dissipate heat forming inside it, result is thermal runaway and whole content going up in whoosh or bang with superheated steam and oxygen spread all over the place. And many things can start/catalyze that decomposing. Most transition metals and their compounds do it, lots of organic compounds (splash of peroxide on wool would turn it to flaming torch) ordinary dirt in its various compositions and universal availability. Any randomly named substance has 50-50 (or better) chance to catalyze the reaction. John D. Clarke's book Ignition! An Informal History of Liquid Rocket Propellants has whole chapter from the joys of it. Google for book's name +pdf and you'll find it.
I know it was war and all but making people get into a machine like that is pretty evil, the plane i get it, it was desperate and it worked, but the submarines wtf.
Sometime in the mid 1950s, there was a Hydrogen Peroxide explosion in Newport, R.I. at the navy’s NUOS (Naval Underwater Ordinance Station) that killed two of my father’s coworkers who were working on a torpedo. I was around 5 to 8 years old but remember it well. The Hydrogen Peroxide powered torpedo was eventually scrapped.
Fun Fact: Post WW2 3 unfinished Type 21 pressure hulls were converted into beverage tanks for a german beverage company (Rossmann, Frankfurt am Main) and remain in use today.
Actually it wouldn't do instant serious damage to skin... There are far more reactive things. Like how about substance igniting already oxidized things like sand? Or really anything, including asbestos, bricks and concrete? Just read John D. Clarke's book Ignition! An Informal History of Liquid Rocket Propellants for whole lots of fun. Google for book's name +pdf and you'll find it.
'boot' ? - as in shoe? I think you'll find that the German 'boot' for 'boat' is actually pronounced closer to 'boat' than the way and Englishman would pronounce 'boot' meaning a a shoe with a partial shin covering.
@4-Methylaminorex and yeah I know what you really meant by BP. Just thought I'd fk with you since you're too scared to use the actual words. No race is superior to another. All innocent people deserve to live.
I read somewhere that some Scandinavian countries were in the 1980's experimenting with Diesel powered submarines that had a huge, super-insulated tank of liquid oxygen on board. They could run the Diesel while submerged. Not as good as quiet as a nuke boat, but still useful under some circumstances.
Not just in the 1980s: Some of the newest Swedish "Gotland class" submarines operate in a similar way. They do indeed have a large and very well insulated liquid oxygen tank, and have conventional diesel engines, but they only use those for surface running and do not use the oxygen to run the diesels while underwater. There is actually a pretty good reason for this - if you feed pure oxygen into the air intake of a diesel engine instead of air, it runs far too hot and can even melt the pistons and cylinder heads. The combustion is so much hotter (especially when you take into account the fact that diesels run at high compression ratios) that it is just about impossible to pump enough coolant through the engine to take the excess heat away fast enough. Using aluminium cylinder heads and pistons was tried for this (since aluminium is a much better heat conductor than steel), but that presented an even bigger and more catastrophic problem - when fed with pure oxygen, the aluminium cylinder heads would not only melt but actually burn the metal. This was discovered when the first experimental engine was started up and promptly spat huge clouds of aluminium oxide out of its exhaust pipes, followed shortly by the cylinder head explosively separating itself from the engine block. The Swedish company "Kockums" came up with a much better idea: They retrofitted the submarines with an extra section which housed a large and fairly powerful Stirling engine. This operates a bit like a steam engine, except using air as its working fluid instead of steam - and since it is an external combustion engine, the same charge of air filling the cylinders can be re-used over and over again, so it does not need to take in fresh air from the atmosphere. This type of engine works by exploiting the flow of heat from a heat source to a heat sink, and in a submarine (or in a surface ship, for that matter), the surrounding ocean makes an excellent heat sink. For the heat source, it burns diesel fuel in a continuous combustion chamber, using oxygen from the big tank. The exhaust products are expelled overboard, using an exhaust compressor to do this at depth. The Stirling engines used in Swedish submarines generate 100 horsepower, which is enough to propel the sub to 5 knots submerged. The oxygen tank holds enough to maintain this power level and hence submerged speed for about 2 weeks, and I think some of the boil-off oxygen gas can be used to replenish oxygen for the crew to breathe - though this is a miniscule amount compared to how much the engines use, since the Gotland class is fairly small, with less than 30 crew. It is an incredibly capable submarine though - in war-gaming exercises it has demonstrated the ability to infiltrate American aircraft carrier battle-fleet by stealth, achieving an attack position where it could have sunk the carrier if it had fired a torpedo, without being detected by either the carrier itself or any other ship present. It is therefore fortunate for both Sweden and America that they are allies, so the Americans responded to this by asking the Swedish government if they could borrow one of the Gotland class submarines to find out exactly how they managed this.
My father was a fire control officer on a tin can in the North Atlantic. He told some wild tales of horrendous weather and, of course, U-Boats and depth charges. ASW was my warfare speciality and logged over 4000 hours in P-3s. Acoustically, a diesel sub on battery is just an acoustic hole in the water. I’d rather go against a nuc.
AW 1986-2012. Monitored the Kursk message traffic. Only squadron with hot contact on the Mike....the Komsomolets. Was on a cold pattern looking for him, returned from debrief, only to learn from CNN on AFRTS that he went down.
The scary modern thing: the latest nuclear submarines are just as quiet as diesel-electric subs running on battery power. Reasons: quieter drive systems, better insulation of coolant pumps for nuclear reactors and even quieter propulsion blades, thanks to a shield around the propellers. I believe the USS _Virginia_ class subs have these features.
John D. Clarke's book Ignition! An Informal History of Liquid Rocket Propellants has whole chapter from the joys of it. Google for book's name +pdf and you'll find it. In short molecule is unstable and there's exothermic self decomposing going on at some rate. And if you can't keep tank holding peroxide cool, you'll have thermal runaway and whole content going up in big whoosh or bang.
I got a drop of 30% hydrogen peroxide on my fingernail once. I thought it was water. I didn’t think much about it. About 20 minutes later my finger hurt. My fingernail had turned white and fell off.
Interestingly, the Type XXI electroboat was a follow-on to the peroxide-powered Type XVII u-boat. The kriegsmarine set-out to make a full-sized ocean-going u-boat based-on the Type XVII, the Type XVIII; this boat would've been a wonder-weapon, capable of cruising at 25 kts underwater; but even with the lower half of the hull being one giant peroxide tank the Type XVIII had disappointing range; plus, the hydrogen peroxide was as you mention, hellish stuff, and so difficult to make that supplying enough of it to feed a whole class of u-boats was not realistically feasible. So the designers of the Type XVIII were moping at the bar one day, disappointed at their dream u-boat design being a non-starter, and one of them said (in German, I imagine) "Hey - I've got an idea! That big peroxide tank that takes-up the whole bottom of the Type XVIII? Why don't we fill that tank with batteries and equip the Type XVIII with diesels and big electric motors instead of Walter turbines?" Thus the Type XXI was conceived - and virtually every postwar diesel-electric submarine owes a great deal to the Type XXI. If you find yourself in Bremerhaven, I heartily recommend a visit to the Wilhelm Bauer; one of its advanced features was the fitting of small (relatively-speaking) creep motors for silent running; these motors turned the main propeller shafts slowly, via rubber v-belts; hence, they were virtually silent.

VERY interesting! I wondered about the use of hydrogen peroxide for AIP purposes. Given current AIP systems, it would be interesting to know how they solved the problem. I'm sure it's too classified for casual interests.
We were taught at Fleet Sonar School that if we heard an underwater explosion while pursuing an unidentified sonar contact to classify it as a soviet "Quebec" class. They were Russia's attempt at a hydrogen peroxide sub. In 2000 Ivan lost the Kursk due to one of their hydrogen peroxide torpedoes cooking off. Poor maintenance and even worse record keeping killed the whole crew.
The torpedo that sank the Kursk was also a dummy training torpedo, it didn’t have an explosive warhead, and part of the reason why it exploded. The welds weren’t to a higher standards because it was a dummy torpedo, and the manufacturer didn’t know that peroxide was being used and just pumped out torpedoes shell housing l, so neglected the manufacturing quality standard.
they should have replaced the ships inner atmosphere with an inert gas and have the crew wear breathers - that would probably help make it less volatile
I did watch the UA-cam video on the Messerschmitt Me-163 and I must say I'm not too keen on breaking the sound barrier while I'm screaming in agony being dissolved alive or while my plane is pointing straight down at the ground. Or both.
The torpedo was also a dummy training torpedo, it didn’t have a explosive warhead, and part of the reason why it exploded. The welds weren’t to a higher grade because it was a dummy torpedo, and the manufacturer didn’t know the danger of peroxide, and that these torpedo needed to be made to a higher standards as a normal torpedo
Very informative. Fills the gap between diesel-electric and nuclear propulsion development. However , "Boot" in German is not pronounced like footwear but "boat" as in English: U-Boot is pronounced U-boat.
How about a fuel cell boat? remove the engines, replace them & the batteries with fuel cells. replace the fuel with cryo tanks for LOX & Liquid hydrogen. reduce the crew - no more need for engine mechanics. should be super quiet. not really sure about the range, though.
"Don't stop here, this is bat country!" "I don't want to kill you, I just want to carve a little Z in your forehead!" "Look over there, two polar bears fucking!" One of the funniest and most quotable movies ever.
Is the thumbnail click bait? You be the judge. No and Yes. Did this type propulsion system cause a sub to be lost/go down with all hands possibly meaning that the crew did in fact dissolve? Yes! Is there a story in the video with Hunt for Red October style excruciating play by play detail about an entire crew being completely dissolved? No
Hydrogen buildup from water in the batteries (electrolysis?) + an oxygen rich environment = BOOM! (My guess before watching the vid, anyway.) (Edit- Nope, i lose: I forgot about H2O2. Yikes.)
Surprise!! It didn't actually happen, as so many people are crying about in the comments. "WHY WOULD SIMON LIE TO US?!? WHY??! 😭🥺😥" 😂😂😂 Relax my dudes it's nbd

I read somewhere that some Scandinavian countries were in the 1980's experimenting with Diesel powered submarines that had a huge, super-insulated tank of liquid oxygen on board. They could run the Diesel while submerged. Not as good as quiet as a nuke boat, but still useful under some circumstances.
Not just in the 1980s: Some of the newest Swedish "Gotland class" submarines operate in a similar way. They do indeed have a large and very well insulated liquid oxygen tank, and have conventional diesel engines, but they only use those for surface running and do not use the oxygen to run the diesels while underwater. There is actually a pretty good reason for this - if you feed pure oxygen into the air intake of a diesel engine instead of air, it runs far too hot and can even melt the pistons and cylinder heads. The combustion is so much hotter (especially when you take into account the fact that diesels run at high compression ratios) that it is just about impossible to pump enough coolant through the engine to take the excess heat away fast enough. Using aluminium cylinder heads and pistons was tried for this (since aluminium is a much better heat conductor than steel), but that presented an even bigger and more catastrophic problem - when fed with pure oxygen, the aluminium cylinder heads would not only melt but actually burn the metal. This was discovered when the first experimental engine was started up and promptly spat huge clouds of aluminium oxide out of its exhaust pipes, followed shortly by the cylinder head explosively separating itself from the engine block.
The Swedish company "Kockums" came up with a much better idea: They retrofitted the submarines with an extra section which housed a large and fairly powerful Stirling engine. This operates a bit like a steam engine, except using air as its working fluid instead of steam - and since it is an external combustion engine, the same charge of air filling the cylinders can be re-used over and over again, so it does not need to take in fresh air from the atmosphere. This type of engine works by exploiting the flow of heat from a heat source to a heat sink, and in a submarine (or in a surface ship, for that matter), the surrounding ocean makes an excellent heat sink. For the heat source, it burns diesel fuel in a continuous combustion chamber, using oxygen from the big tank. The exhaust products are expelled overboard, using an exhaust compressor to do this at depth.
The Stirling engines used in Swedish submarines generate 100 horsepower, which is enough to propel the sub to 5 knots submerged. The oxygen tank holds enough to maintain this power level and hence submerged speed for about 2 weeks, and I think some of the boil-off oxygen gas can be used to replenish oxygen for the crew to breathe - though this is a miniscule amount compared to how much the engines use, since the Gotland class is fairly small, with less than 30 crew. It is an incredibly capable submarine though - in war-gaming exercises it has demonstrated the ability to infiltrate American aircraft carrier battle-fleet by stealth, achieving an attack position where it could have sunk the carrier if it had fired a torpedo, without being detected by either the carrier itself or any other ship present. It is therefore fortunate for both Sweden and America that they are allies, so the Americans responded to this by asking the Swedish government if they could borrow one of the Gotland class submarines to find out exactly how they managed this.

In short molecule is unstable and there's exothermic self decomposing going on at some rate.
And if you can't keep tank holding peroxide cool, you'll have thermal runaway and whole content going up in big whoosh or bang.
I got a drop of 30% hydrogen peroxide on my fingernail once. I thought it was water. I didn’t think much about it. About 20 minutes later my finger hurt. My fingernail had turned white and fell off.
The burning question. How do you get a droplet on you in any circumstance that you might think it was water?!?!
Neal Stephenson wrote of such a sub in his book Cryptonomicon. I wasn't sure if it was a fictitious invention.
So the thumbnail was click bait bs and no crew was dissolved. Color me shocked
It doesn't say it did just says "dissolved crews" you made the implications that it happened... that's on you
@@kingjellybean9795"Dissolved its crew alive" ... might implicate it did exactly that. The guy in the Me 163 also didn't get "dissolved" btw...
“Thanks for watching!” - Factboy, allegedly.
Really? Thumbs down, then.
@@kingjellybean9795It says “dissolved its crews alive!” That implies crews were literally dissolved.
Interestingly, the Type XXI electroboat was a follow-on to the peroxide-powered Type XVII u-boat. The kriegsmarine set-out to make a full-sized ocean-going u-boat based-on the Type XVII, the Type XVIII; this boat would've been a wonder-weapon, capable of cruising at 25 kts underwater; but even with the lower half of the hull being one giant peroxide tank the Type XVIII had disappointing range; plus, the hydrogen peroxide was as you mention, hellish stuff, and so difficult to make that supplying enough of it to feed a whole class of u-boats was not realistically feasible. So the designers of the Type XVIII were moping at the bar one day, disappointed at their dream u-boat design being a non-starter, and one of them said (in German, I imagine) "Hey - I've got an idea! That big peroxide tank that takes-up the whole bottom of the Type XVIII? Why don't we fill that tank with batteries and equip the Type XVIII with diesels and big electric motors instead of Walter turbines?" Thus the Type XXI was conceived - and virtually every postwar diesel-electric submarine owes a great deal to the Type XXI.
If you find yourself in Bremerhaven, I heartily recommend a visit to the Wilhelm Bauer; one of its advanced features was the fitting of small (relatively-speaking) creep motors for silent running; these motors turned the main propeller shafts slowly, via rubber v-belts; hence, they were virtually silent.
HMS Exploder (Explorer)😉
Blond bomb-shell takes on a different meaning.
Don't forget the HMS Excaliboom.(Excalibur)

Two boats that brought their own depth charges, potentially saving the enemy the trouble.
A really interesting video!
I had heard of Germany's "Elektroboots" but I hadn't heard of these submarines until now.
Very Bizarre Submarines, Cheers from oversees the United States
Overseas* oversees is a very different word
@@cleverusername9369Overseers (verb- they oversee) could also kinda apply, though, given the post war German scientists that went to the US/UK/USSR...

So many "electric boots" I now have Benny and the Jets from Elton John stuck in my head.
Keep trying to replace it with memories of Das Boot, but no that not great song is still in my damn head
Buh buh buh BENNEH!! BENNEH!!! BENNEH AND THE JEHHHHHHHTS!!🎶
Good story. You spoke lots of words. 👍
Hint: double vowels ( aa, oo, ee) are pronounced like the name of the letter in German. So "Boot" is pronounced like "boat" not the footwear.
Nice and informative vid!
VERY interesting! I wondered about the use of hydrogen peroxide for AIP purposes. Given current AIP systems, it would be interesting to know how they solved the problem. I'm sure it's too classified for casual interests.
good content always
What were the electrical stats of the drive motor & batteries?
ie: volts, amps, watt-hours, etc...
Should talk about U-480. The first stealth submarine.
HTP, what turned the Russian Kursk into a permanent submersible
Actually the Kursk was refloated & moved to a dry dock. The remains of the forward torpedo room was cut off.
14,601 tons...i don't know but i'm going to guess that means they sunk one ship?
Maybe more like 2 or 3 small ones? They mostly sunk merchant ships as far as I know
I find it funny that the US was like nope to dangerous not interested and Britain I think you said was very interested in it.
Wow 😮
And I thought human spontaneous combustion is uncanny, I never thought there would be another in the form of submarines
We were taught at Fleet Sonar School that if we heard an underwater explosion while pursuing an unidentified sonar contact to classify it as a soviet "Quebec" class. They were Russia's attempt at a hydrogen peroxide sub. In 2000 Ivan lost the Kursk due to one of their hydrogen peroxide torpedoes cooking off. Poor maintenance and even worse record keeping killed the whole crew.
A history of submarines would have been a more appropriate title for this video.
"Boot" in German is pronounced just like "boat", not like the shoe. 🤦♂️
The torpedo that sank the Kursk was also a dummy training torpedo, it didn’t have an explosive warhead, and part of the reason why it exploded.
The welds weren’t to a higher standards because it was a dummy torpedo, and the manufacturer didn’t know that peroxide was being used and just pumped out torpedoes shell housing l, so neglected the manufacturing quality standard.
Adding in the bit about the Kursk at the end was very interesting.
You my friend are amazing. I could listen to you all day.
I do, tap in to the Whistlerverse via podcasts while driving, superb
I love pointing out to people who are putting Hydrogen peroxide on their cuts...that it's torpedo fuel :)
Excellent video.
they should have replaced the ships inner atmosphere with an inert gas and have the crew wear breathers - that would probably help make it less volatile
Also, the aesthetic.
I want to see the surviving electric u boat converted to lithium batteries and compared to the old version
Remake Silent Service Pleeeeese!
Is it just me or does Eugene B. Wilkinson look like Fred Armisen?
I did watch the UA-cam video on the Messerschmitt Me-163 and I must say I'm not too keen on breaking the sound barrier while I'm screaming in agony being dissolved alive or while my plane is pointing straight down at the ground. Or both.
Free submersible cookies!
Ah.....pre EV submarine
Sssshhhhhh, if Elon hears we'll end up with a T-boat (Teslaboot) ---- lol
Nice
Someone should find out how to pronounce the German "boot" or translate it as "boat" - seeing it has nothing to do with foortwear..
How do you translate foortwear 😂
Note to self;
1) Never join the Navy.
2) DO NOT EVER NEVER GO INSIDE A SUBMARINE!
didnt know a peroxide torpedo took out the Kursk.
The torpedo was also a dummy training torpedo, it didn’t have a explosive warhead, and part of the reason why it exploded.
The welds weren’t to a higher grade because it was a dummy torpedo, and the manufacturer didn’t know the danger of peroxide, and that these torpedo needed to be made to a higher standards as a normal torpedo
Very informative. Fills the gap between diesel-electric and nuclear propulsion development. However , "Boot" in German is not pronounced like footwear but "boat" as in English: U-Boot is pronounced U-boat.
I have to wonder why Russia thought this was a good way to propel torpedoes after knowing the risks.
Damn, that guy's forehead just keeps going up! 1:11
Bahhaaahahahaa kinda thought it was a gag and would just keep going 😂
HTP torpedoes were phased out due Kursk incident in the Russian Navy. I thought it was the last one to use those.
Four person crew, blonde and tear shaped. It's the Beatles yellow submarine
The flickering effect you put in the videos is making me nauseous and giving me headaches
Strange to pronounce the word "boat" as in German, but nothing else - e.g. Doenitz 😉
Germans don't even pronounce it like that, it's more like 'bort', definitely not like the footwear 'boot'.
How about a fuel cell boat? remove the engines, replace them & the batteries with fuel cells. replace the fuel with cryo tanks for LOX & Liquid hydrogen. reduce the crew - no more need for engine mechanics. should be super quiet. not really sure about the range, though.
Nautilus was the first true "submarine". What went before Nautilus were in fact SUBMERSIBLE torpedo boats, not true submarines!
"The Sschnokell" 😊 My girlfriend can't understand Simon. 😅 Meanwhile I love the accent dude. ❤
Germans know how to build good boats .
So glad they found a safer alternative. Just wish Russia would have paid closer attention to the missiles before the K
Is that Herbert Lom with the binoculars at 9:30?
Torpedoes were developed pre WW1, not WW2 as stated here (timestamp 11:34 )
The first manned spacecraft also used hydrogen peroxide to power its turbopumps.
and secondary to the script's intent was the blithely entertaining simon abjectly butchering the german language. good vid, tho!
Thumbnail is misleading
I was kinda thinkin of that film Fear&Loathing when he threw that orange at dr gonzo
"Don't stop here, this is bat country!"
"I don't want to kill you, I just want to carve a little Z in your forehead!"
"Look over there, two polar bears fucking!"
One of the funniest and most quotable movies ever.
How did it affect the wales?
1943: Let's make a submarine that can dissolve it's crew. 1944: Let's make a rocket plane that can dissolve it's crew. Talk about not learning.
Is the thumbnail click bait? You be the judge. No and Yes. Did this type propulsion system cause a sub to be lost/go down with all hands possibly meaning that the crew did in fact dissolve? Yes! Is there a story in the video with Hunt for Red October style excruciating play by play detail about an entire crew being completely dissolved? No
So, America took the rocket nazi, and Britain got stuck with the hair bleach submarine nazi?
Does simon own this channel? Or still under contract
The schnorqul?
Admiral 'Durr-Nits'........Not 'Donn-itzz'..😉😂 Great video as always though!
I love your channel but the music in the background of your dialog is very distracting
Hydrogen buildup from water in the batteries (electrolysis?) + an oxygen rich environment = BOOM! (My guess before watching the vid, anyway.)
(Edit- Nope, i lose: I forgot about H2O2. Yikes.)
Okay, never-mind; I don't want a submarine.
From the thumbnail for this video, I read "dissolving the crew alive" and I was like, nope, I'm not watching that. See you guys in the next video.
Surprise!! It didn't actually happen, as so many people are crying about in the comments. "WHY WOULD SIMON LIE TO US?!? WHY??! 😭🥺😥" 😂😂😂 Relax my dudes it's nbd
The Russians developed peroxide torpedos that were extremely dangerous. A failure of one may have sunk the Kursk.
“Bizarre Thumbnail Click Bait”
I paid attention to the end disagree with the click bait accusation.
Don't vacuum distill H2O2, in case you were thinking of it. 0/10, would not recommend.
Peroxide was also the culprit of something like Kirsk.
It’s Kursk, not Kirks
The German word “boot” is pronounced the same way as the English word “boat”…
No.
Wrong.
