"It's kind of like trying to throttle a full size and very angry snake... Which by the way, I've done." Jaime Hyneman 😂
which brings to question what animals he had in his pet shop pre-mythbusting days
@Adj72 how did mythbusters start
@@TheVindicitive An Australian producer had the original idea. But their production company didn't think it would work. So they sold the idea to the Discovery Channel who had connections to Jamie & Adam. & the rest as they say is history or Myth Busting.
lolololololololol
I love how casually he emptied that gun. He's an absolute machine of a man. Impressive in every way.
6:31 I agree with Jamie that being in a boat blown upside down by an explosion would be "Kind of upsetting."
A "significant emotional event"
A "mild inconvenience" one might even say.
seeing Jamie coming with the gun is both awesome and somewhat terrifying XD
@viirrvill shut up nerd
a classic case of * don´t worry of a bullet with your name on it, worry about the hundreds with "to whom it may concern" on it.*
That makes no sense.
@@pistonburner6448 Clearly you've never been in a battle.
An M60 barrel, straight from the factory, would not be destroyed after a few hundred rounds. I wasn't able to find numbers on the quick but the barrel lifetime of common machine guns is typically stated as at least 3,000 rounds.
Sure, in combat, the barrel is commonly exchanged after only 100-200 rounds of sustained fire. Why? Mainly because of heat, to a lesser extent because it gets dirty (fouling), e.g. carbon residue from the burning propellant and copper residue from bullet jackets. But those are usually fixable by letting the barrel cool off a bit and, if necessary, giving it a good cleaning.
21:16 "Ticking away the moments that make up a dull day"
"Fritter and waste the hours in an off-hand way..."
"Digging around on a piece of ground in your hometown...."
"Waiting for someone or something to show you the way"
admit it, we ALL want their job
We dont need to, we can do it on the street (at home you cant)
One other detonation that could be the cause of the 'being blown out of the water' phrase might be a magazine explosion in a heavily armoured vessel like a battleship. There's reports from the sinking of the USS Arizona at Pearl Harbour and other magazine detonations of the ship 'being lifted 10 feet or more' by the blast, which makes sense if you think about how the armour on a post dreadnaught battleship's armour is laid out. The thickest armour is on the sides (the belt), with deck armour protecting from falling shot (and in later years, air attack), but practically no armour on the bottom and all the ship's most important or vulnerable components (such as the engine and the magazines) inside this open bottomed box. So if the magazine goes up, the easiest route for all that explosive force is down, and Newton's 3rd law of Motion accounts for the ship moving up (and given we're talking somewhere between 30 and 50 thousand tons of steel moving up, 10 foot of movement is a *lot* of movement).
As an aside to this, the idea that it comes from submarine crews has some merit as well. Torpedoes generally strike a ship below the armour belt (there is anti-torpedo defences, but they work differently to armour plate and a lot of older vessels either had poorly designed anti torpedo defences or none at all), so a torpedo strike can have a better chance of hitting a ship's engine spaces or magazines etc. So, although I admit I don't have any solid proof of this, I can see the logic that they saw a fair share of ships being lifted up in the water by an explosion. Not flying through the air, granted, but still 'lifted out of the water' even if only a little way.
There is actually footage of this, Tirpitz for example was hit by several tallboys and many eye witnesses saw the ship literally being lifted and tossed to the side, from the bomber footage, it does support this somewhat although its hard to see if the ship is really being lifted.
There several footage of merchant ships being torpedoed and splitting in half literally being lifted in the middle and both sides tossed to their sides, but thats hardly the entire ship.
Really appreciate the uploads! Plenty I've seen already back in the day, and TONS from S6 and on I've yet to see. Thank you 🙂
34:30 "Where's the Kaboom? There was supposed to be an earth-shattering Kaboom!" XD
This has already been tested in full scale using battleships and aircraft carriers, in something called Operation Crossroads. It would have been epic if Adam and Jamie had replicated it.
34:30
the nemesis of every explosives gag ...
who gets to go check the bomb?
In the Battle of Jutland in WW1 some of the British battleships were really flying into the air!
I miss this program. Science made fun .. they sometimes missing important clues,but got back on some of them.
Im still hoping Discovery Channel will get this show back for the next generations.
Btw,loved the teenage mythbusters episodes,but it was definitely written by the makers and not honest young mythbusters reactions in my pov. 🤔😉
@44:49 "Your only supposed to blow the bloody doors off" (Charlie Croker, 1969)
I'm surprised a wiper motor wasn't used. Right speed, right action, easy voltage, OTS from a parts store
You should call that machine "Robo Rambo"
This deserves more than one like folks...
@@toddbob644 Fishing for likes of your own joke.. how low can you get?
That' was awesome! Wow!!!!
I cant believe this is where I'd get breaking bad spoilers
9:22 Thats bad-ass! 😂
never stop doing this Guys.
they stopped eight ys ago...
What they don't do is try the boat from different tank sizes, only 1 size, so very hard to say half depth is conclusive
Since before WW2 torpedoes were fitted to detonate under enemy ships with magnetic detonated when it sensors a steel hull. They could also use a contact fuse against a detonate on the side of the hull. when detonating under most ships could break a split of the hull as the ships center was lifted up and a ships back broken. At the time magnetics were still unreliable in part due differing magnetism of different region. And many other US torpedoes had faults that US Navy leaders would not investigate the faults that were actually easy to fix. But thousands of lives were lost during the war due to these failures. Basically sending out defenseless subs on useless mission. Once the navy agreed to test the faults the US submarines became very destructive of the Japanese. Many heavily armored ships like battleship could survive an underwater detonation despite heavy damage. And may require more hits to sink. One of the worlds biggest battleships had 17 torpedo hits plus air dropped bombs to make it sink. Once the battleships ammunition was blew it in half.
The whole tank of water lifted off the floor pmsl
I have never been a fan of red cars and the mark 4 has never been on the top of my list but i must admit this one has changed that it looks so good. Job well done. 👏
"The boat has GONE AWAY."
while I see Jamie firing using a bipod, I'm just waiting for the tripod scene... I don't think that is going to come however...
I recognise that Airfix PT model boat from my childhood. Oh, about 40 years ago. :)
9:22 i thought he had googley eyes there for a second
The tumbling rounds would be as a result of going through the car - as a ricochet.
The amount of explosive used was massively excessive. A quarter of the amount would have been enough and maybe have worked.
You're gonna need a bigger boat :)
why did the announcer call the bipod a tripod?
Glad to know you're not the only one irritated by that.
Actually, from what I've seen, when the explosion happened, the boat was hit and the various part separated:
The steel hull actually lifted, but wasn't totally seen because of the geyser that covered it and sank almost immediately
The wooden superstructure, well... it detonated.
That's why we saw only little wooden debris, because the steel hull sank before the geyser fell down
If the expression "blowing it out of the water" came from submariners they'd be firing torpedoes that exploded on (or near) impact with the target, not depth charges that exploded well below the target; or maybe the ship blew up after taking damage to sensitive areas or cargo, i.e. an explosion within the ship, not dozens of meters/yards below the surface. It seems to me they skipped the part of trying to replicate the actual myth after one small scale test and went straight for replicating the outcome with that one. Still fun of course but a bit out of character.
It also seemed to be missing a lot of detail, I mean... there was no thought given (or at least, none shown in the final cut of the show which we see) to the relative sizes of the explosive as compared to the boats/ships (a whole torpedo's worth of ANFO compared to that tiny boat is just... _so_ far removed from being in any way comparable to a submarine torpedoing even the smallest of military vessels, it's _wildly_ overpowered), or how heavy vessels being fired at by submarines would be (which would affect the dynamics of how the explosion affects the ship _enormously_ ), or even to like... practical realities of testing like the pressure wave reflection from the huge explosion in the tiny little small-scale tank, and it's honestly a little disappointing for that reason. As you say, it feels much more like a race to see a boat pop out of the water at any cost, rather than an actual thoughtful test of the supposed myth at hand.
I think it compares especially poorly to the level of detailed thought which was shown going into the other story in the show; we see a lot of the practical nitty-gritty of like... what are the physical and engineering concerns, what are the potential edge-cases, what's realistic in the context of the myth, etc., which is wonderful to see! It's sadly absent in what we see of the boat story though, and having the two of them in such sharp contrast side by side make the difference seem very stark.
Even Jamie's comment at the end is odd and feels out of character, like... "unless your boat is very strong"? I mean... if it really came from submariners torpedoing vessels, then a decent chunk of their targets would be fully loaded with fuel, supplies, weapons, etc. and armoured specifically to try and withstand (or at least mitigate the damage of) things like torpedo strikes? Somehow I doubt the lightly constructed and as far as we see entirely empty little boat they had was designed with "withstanding 1000lbs of ANFO going off 10m below the water's surface" in mind. There are just so many variables which we don't even see being considered or discussed which really feel like they would have had a huge impact on the myth.
Potential alternate explanations also never figured into the episode; one which occurred to me (admittedly an actual idiot) came from the small scale test... the explosion seemed to displace a lot of water downwards, so maybe it just _looked_ like ships were blown out of the water, as water was blown away from the ship's hull, temporarily revealing more of the hull below the waterline?
Agreed -- pretty sure I have seen footage of boats getting hit and lifting up in the middle and cracking in half?
My thoughts on this one is they didn't investigate the size of the explosion without the boat on top. The small scale tests showed a bubble of a particular size. They should of done a full scale test with the anfo near the top and measured the resulting bubble that pushed below the water to get an estimated size. Then drop the anfo to a depth that would mean just the top of the bubble, or maybe the top one 5th is all that reaches the boat. Just to replicate the myth. But I do agree, a torpedo only explodes once it hits a target, unless it is remote detonated.
@@crazyphrog6289 To be fair, I think some torpedoes (even as far back as in WW2) are/were equipped with like... magnetic detonators? Using the magnetic susceptibility of steel ship hulls and how they affected the magnetic fields they sailed through to trigger detonation.
I went through a bit of a naval architecture hyperfixation/special interest phase a couple of years ago, and though I was less interested in military stuff I seem to remember hearing or reading that magnetic detonators were a huge problem for... I think the US(?) navy? Because they were tested in one particular area of the world, so their sensitivity was calibrated for that particular area, but the differing strengths of the earth's magnetic field around the world kept meaning that they weren't detonating properly when they were fired at ships in other places that they weren't calibrated properly for. (and if I recall the story correctly, the body responsible for designing/testing them outright refused to consider the possibility that their torpedoes and/or procedures didn't work as intended or had any flaws, and so blamed submarine captains/crews for "just being rubbish" (paraphrased) for ages?)
So with potential non-contact detonations, it's possible that torpedoes which may or may not have given rise to the myth might have detonated with some distance between them and the ship's hull
an additional thing I've thought of now is like... what if a torpedo managed to rupture a ship's hull, breaking into an ammunition or fuel or some other kind of explosive/flammable material storage, setting off an explosion which then had a convenient breach in the hull (presumably pointing downwards) to direct the force, which could help to push the ship upwards? Another aspect which wasn't considered in the story a shown on screen
You're only supposed to blow the bloody doors off!
Iconic, my cocaine line lol
that explosion made my jaw drop, that was WAY bigger than I expected. No wonder the thing got obliterated.
Since you've asked Adam, I've not seen breaking bad, but I'm not really upset by the spoilers.
Love the fact thay used a British frigate instead of a US one in the cartoon
9:27 Jamie in those mirror glasses would have looked cool, but.... A reflection in them makes him look like a cartoon
The tank tanked
My favourite weapon to fire during my time in the Australian Defence force. Watching tracer fire at dusk is a sight to behold...
That intro has Devil Went Down To Jamaica vibes
An M60 is not artillery, it fires 7.62 mm bullets, artillery is above 20mm. And it was not a tripod, but a bipod, having only 2 legs...
Artillery is used as a colloquialism as a comparator.
"get out the heavy artillery"
30:25: The Mythbusters have inadvertedly caused the develompent of a game called: Getting over it
Very cool
Another kink in the armor of the boat-out-of-water myth is that their test boat wouldn't have been built nearly as sturdily as a warship would
They are not taking into account that in the ocean, there’s more than 30 feet to the bottom (at least where the subs were operating). The ships they were firing on were usually in better condition, and that when the ships WERE blown up out of the water, but not immediately blown up, something WRONG had happened.
Lurv the M60 -in-the-trunk, completely awesome reconstruction of one of the outstanding moments of an outstanding series, well done guys.
Modern torpedos can be programmed to destroy ships not by direct impact but by exploding under de keel, breaking it as show on the first part of the video, methinks that it was throughly tested before deployment
ThunderfOOt busted nice myths too.
Couldn’t have done that first test outside? PANIC! WATER IN THE SHOP!
Warships are much more robust at the hull!
>They're testing a WW2 myth
>at 2:20 they show a 1950s Whitby-class frigate graphic
>evening ruined.
I know I am getting old when I watch the explosions and all I think is: "man the poor people who have to clean up that mess"
Since the bomb was made using a septic tank, you could say they used a shitload of explosives there.
Walt got lucky, yes. But he also had the luck of a protagonist.
i like to think that off-screen, walter would have done a test firing before the big event. he's not the kind of guy to leave something like that to chance.
The Discovery Channel couldnt sell the show to networks anymore so they decided to run them on yt and make big money, I think this is a trendsetter for other production companies to release full episodes on YT. I wonder if Adam and Jamey are receiving royalty's on this?
would lowering the ampere of the motor work?
I hate when they "bust" these myths based more on their own failures rather than truly proving it couldn't be done. Remember that the halfway distance from the model test was based on the size of the shockwave of the cherry bomb. We have no idea what the shockwave size was of the bomb they put together. Is it possible that it could be done? No idea. Was their test conclusive? Not at all
They used too much anfo at the end lol
21:00 im getting scary idiocrazy vibes watching this..
The last is plausible as I see it, but then they have tinker with both depth and amount of explosive and that would have take a really long time and money which they understandably don't want to bother with.
9:31 Specifically, 7.62x51 NATO. The military equivalent to .308 Winchester. Also probably not realistic to shoulder fire this thing :P For peak performance it's best for it to be mounted to something, like a Humvee or a heli. 11:50 that's a bipod btw ;)
Bang boom boat astromting what a grazing
Nowadays the "Don't try this at home" disclaimer could be replaced with "Try this in Kerbal Space Program"
The M60 is a direct copy (or direct evolution if you like) of the German MG-42. That applies to other combat rifles as well.
Hell, pretty much all "western" weaponry developed after WWII, Including everything from handguns to tank guns, artillery and missiles, is based on German WWII designs.German engineering back in WWII was simply at a whole different level.
This is wehraboo nonsense. The one feature that modern belt-fed machine guns copy from the MG42 is its cammed track belt-feed system. Otherwise they are all gas-operated instead of short-recoil operated and thus mechanically vastly different guns. While it's true that the M60 specifically has a lot of german parentage as a kludge of a FG42 action with a MG42 belt system, the vastly more popular (and better) FN MAG pairs the belt feed mechanism with an upside-down and beefed-up BAR action instead.
Further, WWII era German firearms have actually had very little influence overall. Modern handguns owe basically everything to John Browning and Dieudonné Saive, German WWII rifles are notoriously *bad* outside of the StG 44 (and aside from proving the viability of intermediate cartridges in select fire rifles, modern rifles take no technical elements from it), their optics were trash, I could go on. The technological story in WWII is actually Germany getting distanced by everyone outside of a select few areas that idiots exploit to create a nonsensical mystique around it.

Use water based explosive instead of ANFO
Ok I know its been off the air for years...but the boat has to be In an ocean or deep enough lake the blast waves wont bounce off the bottom and you should use a metal boat ex: a WW2 PT boat.
I believe they said it was a metal boat when they were hauling it in and it still got disintegrated
@@TheTrueBatBrain I wonder how much of the metal hull was destroyed. Maybe the hull instantly sank and the upper wooden parts are what was thrown up high in the air.
WWII PT boats were made from various species of tropical timbers and plywood. There are several documentaries on TH-cam which show some of the steps during construction of PT boats.
i belive the bomb just wasnt deep enough.
Uboat captains seeing a boat lifted out the water would have been if they hit a warships magazine or munitions transport and not from the power of the torpedo, doubtful that even the japanese kamikaze torpedo/subs would have had the tonnage of explosives required.
The demonstration of explosion below the boat was closer to the attack on the Tirpitz by minisubs that damaged its spine by either lifting it up or simply displacing enough water for it to lose the support or a combination of both. Not to forget the tallboy earthquake bombs dropped by the RAF to seal its fate.
Describes it as 'Quite a nice machine.' 🤷♂
Someone knows the Track DI of the intro track?
Too bad they closed the Chabot Gun Range. I used go there all the time, even got my hunting course and license there.
After the first cherry-bomb I was wondering how long the tank would last! Second one got it. I know the Mythbusters know this but water doesn't compress meaning that lovely expanding sphere of destruction pushes the water outward with some force - what is the tank made of? Cool content, explosions are so mesmeric, is it just a bloke thing?
what the name of intro song?
Picking a mid-point between the surface and bottom is totally arbitrary. Why they didn't calculate the relative distance from the boat to the explosive in proportion to the amount of explosive used in the test, I don't know. This seemed very unscientific.
9:22 Jamie looks like he has BOGGLE EYES, like a villain from " Who Killed Roger Rabbit"
Can you try to shoot an object moving away from you at high speed while you are Stationnary to see if this will affect the bullet penetration
Let try test
This one is the last last episode?
Anyone know?
The only boat I know of that lifted out the water was the prince of Wales or the hood can’t remember which one
Hood I think after the ships magazine blew up
@@RobertHarrison-oe3qg yep that was it only like 5 or 7 survivors out of hundreds ….. poor buggers
That was too much explosive, they needed to try a smaller explosive in my opinion. Also i m not sure what they did in smaller scale, scale linear in larger scale.
science *chuckle*
if u look frame by frame it looks like the boat really flew out of it but stayed i the cloud of water and at a certain point u see a big splash maybe the top flew of and the rest sunk ?
same amount of explosive and you need a bigger boat guys lolz
Though I'd have liked to have seen the damaged boat under the water.
And now every fish is dead in that lake.
Blowing a ship out of the water is very much possible. Except it will break apart in two at the point of explosion and it doesn't actually leave the water. It just pushes up far and breaks its keel.
Yeah, I wondered about that, too. Why would the boat leave the water? The water will be displaced by the explosion and push upward and the boat will ride on the water. Since the displacement will be spherical, the force is not evenly distributed along the hull and it will always push harder in the middle than on stern and bow. No ship is made to withstand this kind of force. It will break under its own weight and crack in the middle.
And that is what people saw. The boat was riding on a water sphere up out of the water, breaking apart. Nobody ever said "blowing it out of the water" meant it was literally hovering above any water. It was just above the surrounding water level, but well within (or atop) the water sphere/geyser.
The only reason they declared the Myth busted was due to them not having the funds and time to try again, after their half-cooked plan fell apart. Whatever they said, I do not believe the story that the results of their plastic boat with black powder in a tank can be scaled in any way to a metal hull boat in a flooded quarry with ANFO. That are just too many variables and a lot of them unknown or too hard to calculate. Not even considering that the explosive was probably the correct size, but the boat was not a war ship, its hull too thin. As others suggested, a Patrol Ship or a small Frigate would be the right size.
In my opinion, this myth is NOT busted.
11:00 full 9 yards
Anyone know that intro song?
Sptisc tank
I would not stand under a 48000 lbs boat hanging from straps...
they missed a vital component of the car machine gun it wasnt firing through the side of the car when the trunk popped it raised into position
Not so vital considering it still tore through the building, the side of that car might as well have been a sheet of paper.
Its a bipod!
"blowing it out of the water" if that comes from WW2, than the "boats" in question would most likely be made out of German Steel and not painted Wood.
May I remind you, that the good old Bismarck was under concentrated fire from British ships für about 2 HOURS until the German Crew Scuttled it ?
Exceptionally durable, CHECK.
I stopped watching after Kari, Grant, and Tori were no longer in the show, so these episodes are brand new to me😊
The volume of water and surrounding landmass wasn't accounted for I think... Its not a whole ocean... Less volume more energy concentration
