But thez weren't doing it right. Especially the reading part, using a gramophone stylus can't work, because they work with special shape of the grove. They'd need a laser scanner and some advanced reconstruction to be able to do it.

@@mrkv4k If you can record sound with a fat needle on malleable clay or a fluffy paintbrush on paint you should also be able to replay sound with the same tools. You wouldn't be needing a laser scanner.

​@@stompsandsynths If something recorded a signal by mistake the signal would be so bad and weak that it would require a really precise instruments to read it back.

@@stompsandsynths Fat needle nor fluffy paintbrush are made for sound recording. They can pick up air vibrations (aka sound) and transfer it to the clay or painting, but the signal is going to be weak and its quality gonna be very bad. If you'd want to pick it up, you'd need precise instruments and post processing for reconstruction. Now, the original myth isn't about being able to record good quality sound, but about being able to pick up something. And that is definitely possible and has been done successfully - with the right tools. What they were doing is pretty much nonsensical.

@@leucome 1: to accidentally record a sound the system still needs to be able to record sound in the first place to whatever extent 2: no system has infinite resolution, which means that it will reach a point where it's just not able to represent the information. The less the system is optimal the lower the resolution

Pi-CASS-Ooo!

The wouldn't have redone anything if they didn't have their own doubts or received an overwhelming number of protests about a factor possibly even supported by some independent source.

I mean, it was a tv show, not a scientific journal. I'm sure in many instances the "flawed testing methodologies" have a lot of "producer magic" attached to them as well.

@@alecguevara1835 There are actually episodes where they get upset because the producers are asking them to change how they test to make it _accurate_ to the myth

@@dungeonsanddobbers2683 any episodes besides the palm? cant think of any more off the top of my head, but that might be because "straw through palm" was recently uploaded

They used a way smaller nossle in the follow up tests and didnt compare that to what that nossle would do without the salami. Of course a smaller nossle will make more thrust.

Base test had no nozzle nor any ignition (nox degrades at high temperatures and yields energy :]) the only real thrust they got off the rocket was from pent up pressure releasing once the "super heavy duty nozzles" exploded and released said pressure (also why the 2(?)/8ths worked better than the 5/16ths) You can also see the detail of no flames once the nozzle explodes (like in the original rocket) meaning there's no combustion, just nox venting. Dogshit tests because they didn't have the balls to admit being wrong.

@@viciousslayer They just weren't very experienced with rockets and explosives yet this season. they got way better later on.

I completely agree! They treated it like they were expending something mystical or magical. The brushes were supposed to represent the stylus and the paint was supposed to be the thin medium that can dry up leaving the small waves printed.

It is true that they held the brushes in a way that it is not in favour the recording to happen. But the real problem is that paint is fluidic and the tiny fluctuations of the brushes caused by soundwaves would instantly disappear before the paint dries. When making a vinyl record, they use a very strong needle and they drive it with several hundred watts of power, on a lacque which is already dry and stiff. You see that it is kind of super far from the paintbrush version?

@@pakuma3thing is the recording techniques weren’t invented yet so people have no way to comprehend that they could record anything onto a medium they just considered good for making pots. Anyhow the engraver should be rigid (not like a brush but a straw) and would need to fixed and connected to the sound source or a cone to create any usable results.

Yeah, i immediately facepalmed during the intro shot of Kari screaming into the brush. The paint will not respond to the vibrating brush hairs even if they managed to make them vibrate individually, because the paint drags the hair down and because of it being a rather thick fluid, it will act more like a cushion and not compliment the vibrations. And yeah, putting pressure on the brush also isn't a good idea, plus every hair will have a different vibration reaction to the sound, plus the hairs that actually touch the surface will be smothered by the hairs on top of it and the weight of the paint and pressure put on it. I mean, i'm not an expert, but those are just a few things that we can spot as casual viewers, pretty embarassing sometimes. But yeah, i do love the show still, it's just sometimes i wish that they were a bit smarter. Having said that, i'm not sure what they could've used to record and play it. Not having watched this episode yet just the intro, i guess you need something that can spin at the speed of sound, or at least at the speed that it takes for sound to travel through a hair(or more likely something a little more rigid), and then kinda like a clay kebab spinning fast and the stylus carving the line on it while quickly going up (or down) as to prevent crossing lines. But i'm not sure how they can make the stylus vibrate, other than bass lines and kicks, because the stylus has to be really thin to vibrate fast and strong enough to be picked up by the fast spinning kebab. Maybe they could record 2 seconds per meter or so, if they can actually record, and play it back. (Edit: and also, if the kebab doesn't tear itself apart at those speeds, maybe a centrifuge would be better, with the stylus in the middle radiating outwards onto the clay.)

Not to mention they didn't prep the canvas and used the most basic type of paint. I do not think the masters would have been so loose on their masterpieces

Was thinking the same thing, but likely the impact area and time of contact makes that negligible here.

In this case it doesnt matter since normaly with a sword, you do a downwards swing to allow gravity to do its thing. With the contraption they are just removing the human aspect of how it is normaly used. Even if it was a cutting motion or the contraption, it wouldnt matter as the edge still hits the target.

@@eliaslaban As part of that downward swing, often you would pull back at the same time, which changes it from purely chopping to include slicing as well. There's a reason a proper swinging action cuts easier than just chopping straight

I remember drivers doing this in Australia. My father, a long distance truck driver, didn't believe the hand would work.

That makes it even less likely since japanese swords in the 1700s were still often made using the very poor quality steel and iron in japan compared to much of the developed world at the time.

I think this rocket experiment is still very badly executed. The force they measured is clearly just one explosion, with a few milisec duration. Which can come from the nozzle exploding, or that the rocket is kinda blocked, as you can see on the footage, and the explosion is when the nox is released and gun powder ignites, there is simply a lot of pressure building up and being released quickly when the blockage is shattered. Thrust on a rocket is never one quick explosion. If there would have been any true chemical reaction going on inside the rocket, it would have lasted for at least a few seconds after ignition and the explosion. I love the mythbuster guys, but they sometimes clearly did not give a f, and you could clearly see this on them here as well.

Rocket motors are rated in terms of total impulse, for that they should have taken the integral of the force over time and not peak force.

Because it saves time... Even with superhuman strength, none of the tests worked

@@GCCG76 I don't know how you think a trucks engine could break a windscreen lol but it's funny

I think, if a gun barrel is hot enough... You can make some dent in it with strong cutting strike. Not enough to cut even remotely through but enough to start a myth.

Feel free to volunteer!

OR it's a joke!

Or they assume the gunpowder won't contaminate other foods, especially wrapped in aluminium foil?

I think it would be possible to correlate the vibration the paintbrush was under while painting if you looked at the resulting stroke finely enough. It just would be on a scale so minutely and certainly not encoded in the thickness of the paint readable by a vinyle player that everything they did was doomed from the start.

Nah, the s5 shock resistant tool steel mason sword.

That is Mike Boom, sticking through his head.

There’s something dodgy about it, indeed.

Probably because masterchef was show airing after them and the bbc had the rights to air it in the UK? I don’t know tho…

I guess that it's where the source file is taken from, BBC that is (was probably aired when they had masterchef going). But it's a good thing since the other sources have the awful mono narrator, where as these don't.

MasterChef became really different show after a while.

Wouldn't make a difference.

Yeah, you always cut at an angle, that was a bit annoying, but i do think that it wouldn't have mattered much, as metal on metal at an angle likely just results in a glancing blow. And if it was any hotter, then you might as well hit it with a baseball bat, because at that point anything could cut through wobbly metal.

Doesn't apply to metal. Doesn't have fibers.

I guess it wouldn't have made any measurable difference

It's irrelevant. The myth is about putting pressure on the glass to brace it against damage.

I wasn't happy with how he put his hand against it, i was expecting a full flat palm, ideally right at the spot where the BB hits, to theoretically have the hand simulate a laminated effect. But yeah, on the other hand (pun intended), that type of glass just isn't made to stay in one piece once it has major cracks, so i'm not sure if it would've held together even if the initial blow was softened.
