Steam Powered Machine Guns and Lie Detectors | MythBusters | Season 5 Episode 24 | Full Episode

[@atkelar]

What the lie detector thing was missing, is the "penalty for a false positive" - i.e. in real life, if it's wrongfully telling somebody did something wrong, they have consequences to fear. So their truthful answers will also be given under stress. In this case, a false positive would have no consequences, so the answers are much more relaxed by definition.

[@Damaged7]

It doesn't "say someone did something wrong" it only gives you clues that someone is being deceptive. This is why they are not admissible in court.

[@AeonLibertas]

Adam keeps playing gleefully with balls and what's basically a simple metal tube, nothing more. Jamie: "Yeah, I know it's fun, let me get back to work." That's probably the most succinct characterization of the two possible..

[@sethstatler8480]

Supposedly the two of them couldn't stand each other whatsoever. I'd have to agree Adam is way more enthusiastic than Jamey. As the beginning of each episode says they have a combined 30 years as actors and special effects experts. This is absolutely one of my favorite shows growing up. I am truly grateful for all the years and truly wish I could make a living myself having the time of my life everyday. I'm at a point in life where I am stuck. I have done just about every occupation in one way or another. I am crippled with option overload.

I mostly miss the myths, though. I miss Tory, Grant, and Kari doing stupid stuff and looking like they loved life. I miss learning I was wrong in a fun way that never felt insulting. I miss learning I was right, even if I told no one about it because I didn't want drama in my life. I miss the format, I miss the fun, I miss Myth Busters.

[@Zouna92]

Okay not to be the boo man here, but the last test had them all steal either the ring or the watch which means the lie detector test was a 50:50 chance for all participants... I think they should have done at least 2 runs with someone not stealing something and see if they would have falsely accused someone. Still a very entertaining episode to watch!

[@Gamer3427]

Agreed. A better method would be to have a bunch of items in the drawer and ask each of them. For each item it decreases the chance of accidentally getting the right answer.

[@MatecaCorp]

There was no myth on this show that was less interesting and more flawed than the "lie detector test". No wonder they packaged it with the sweet steam cannon.

[@un2mensch]

It always disgusts me how the polygraph people lie about the accuracy & efficacy of their stupid pseudoscience machine, and about the related scientific research. The fact of the matter is they *need* people to believe it works, in order for it to have the intimidating effect that the operators rely on. The process needs to intimidate people in order to put the subject under stress in order to break their composure and force mistakes and inconsistencies in their answers. A "lie detector test" is less about the stupid machine, and more about the interrogation techniques of the operator. In theory, you might think, if someone is telling the truth they shouldn't feel the stress, right? Wrong! The "false positive" rate of a polygraph "test" is estimated to be about 50%. That is, assuming you're being truthful, there's still a 1-in-2 chance that the operator will conclude that you are lying. For most honest people, simply being falsely accused of something is incredibly stressful, and polygraph tests are *not* designed to be reassuring in any way. Polygraph tests have been an integral part of innumerable false convictions and forced false confessions. If you are someone who cares more about justice than about securing a conviction (ie, you're a normal person, and not a police detective), I believe the more you look into this ridiculous tool of injustice, the stronger your moral conviction against it should be.

[@DasKantholz]

I guess overselling the polygraphs ability is necessary to make it work. If anybody would think they don't work, the polygraph has nothing to detect. Like magic tricks, its about convincing the audience.

[@asadabdulqaabir4006]

You got the point. Polygraphy has never been about rate the sincerity (or insincerity) of your answers. That's scientifically impossible, the mere concept of truth is not about facts but moral standards. Polygraphy Is about press you enough to confess (whether you are guilty or not). And that put it at the same level of sleep deprivation and other forms of psychological torture.

[@XanderShadow]

Part of me wonders if the steam machinegun wasn't fully intended to kill, but was meant to be more of an intimidation factor? I mean, you didn't exactly want to charge a musket line to begin with, even with how innaccurate they could be at range. Would you, as a civil war soldier, want to charge toward a line with a couple of these strange machines hissing and bellowing steam; that suddenly start hurling shot at you in rapid succession? Even if the rounds couldn't penetrate like in the MB tests here.. considering it still broke bone? you hit someone in the chest, head, throat? and they're still going down with internal trauma, concussion ext depending where it hit em. Given the time period, weapons n such of the day and what was going on; I think it'd still have been effective in certain areas of combat, even if only as a deterant.

[@Decastorm666]

Most soldiers would look at that and laugh. But in a serious note not many men of the Union Army would understand velocity, range, or ECT..

[@GaijinGamerGirl]

Yes, add rifling to a spherical projectile, because that'll work...@@AbeYousef

[@HappyBeezerStudios]

There is also the idea that injuring an enemy soldier is more effective then putting them down. With injuries you take more people out of the fight. Think about what it takes to get a soldier back from the front lines. All that equipment and manpower isn't there to shoot back.

[@bambae7669]

You have to understand that the comparison point is artillery fire, from cannons. There aren't a lot of things scarier than artillery fire, but civil war era cannons firing shots you can see travel towards you as you are advancing towards your death would be something else. If artillery can't act as a deterrent against advancing infantry, no amount of blowing steam a mile away from the line will. Anything that doesn't cull men in the thousands where they stand is not comparable to artillery fire by any metric.

[@aj7419]

weapons are designed to kill & maim, not just scare, and this steam gun thing was no exception - when they found out it wasn't good at it, they abandoned it so as not to waste precious time and resources as someone pointed out, artillery would be the benchmark of the day of the most effective killing machines, and this steam gun wouldn't come close to matching even the weakest contemporary gun take the example of a line of these steam guns firing at an opposing line of infantry - cannon loaded with grape/canister shot would be far more devastating to the opposing infantry, and probably far more intimidating as well - not to mention the artillery can fire other shot at further ranges most weapons that have been used as purely intimidation/propaganda were failed or obsolesced prototypes that kind of necessitated some kind of use to mitigate the investment of production (personally i am thinking of numerous big, weird armored vehicles from the interwar/ww2 era)

[@petesbeats483]

The best way to get through the lie detector is to lie on every single question even if it's a simple question. Lol

[@steelwasp9375]

Yes, the best, and which will get you caught. By simple logic and the fact that you're held to your words in court. You'll also have to do mental gymnastics for every answer, and it doesn't really matter what you say if your vitals spike when key subjects are mentioned. The better one is to simply refuse to cooperate and keep silent. Even that will not stop a discerning and capable interrogator from getting at least something. The better better best one, is to actually believe you are innocent. Without a shred of doubt, not deceiving yourself, but knowing you are spotless. A great actor that can fully immerse themselves in their role, mentality and all, should be able to pass just fine. The alternative better better best one, is transcended equanimity, serenity, detachment. But that's just a cheat in general. Of course, the better better better best one is to have the ability to not have to go through the lie detector if you don't want to, in the first place. Or have the machine display the results you want.

@@kaptein1247 depends on how you define lethality. If it's a chance of penetration, it will definitely help, since the pressure would increase.

That car will probably hurt you and might even kill you, but, the worst case scenario, it will be because it crushed your bones, not because it went through you. Besides, a smaller ball at a higher velocity will be more accurate since it can resist gravity a bit better.

The pellet size seams to have been ideal in transfering all the energy to the target nevermind penetration

[@steelwasp9375]

It's just a slingshot equivalent. Maybe at best Joerg Sprave's kind. Very cumbersome, hard to manage, and wasteful slingshot equivalent. Certainly not fit for war in any way. It's a like a barrage of small hammer swings transitioning to punches at a distance. And it will probably break itself after a while and need repairs. It's only effective short range, and a regular old wooden shield will block everything, plate and padded gambeson will do well, too. It lacks a turret, it cannot aim, it needs high precision machining and balance or it will break itself - it was probably never built. Not by the horse and wagon type of guys. It is so wildly ridiculous, the story that this thing was built during the war because they were running out of gunpowder. If they had the leisure and resources to... Why build this thing if you can put a cannon or a just a few gunmen on that armored chassis?

You mean have a huge contraption and a team of engineers manning it just to try and hit some unlucky fella's face? If you tech this thing up a bit, a low to medium velocity mass driver seems feasible. And with supermaterials for the arms, electromagnetic bearings and power, in an airless environment... this simple catapult may be of some use. It still has to be balanced and send an equivalent load backwards if we're to really talk big and high energy here. But a smaller setup may handle the vibrations just fine. In concept, It is very similar to a railgun, except the energy stored is limited by the material strength of the arms, and not the capacitors.

I'm surprised they didn't ramp up the steam machine gun to see what it would take to make it lethal

[@Nikagor]

Well the thing broke, I guess with it being able to spit the bullets this far you could increase the weight and hope it carrys more force, but a higher diameter would also cause more space for said force to disperse upon impact. I actually believe this thing is lethal, yeah one hit might not kill you but a barrage of steelballs raining down range breaking your legs, arms and rips are effectiv enough.

[@mentaya11]

@@Nikagor You could increase weight without increasing size. You'd just need something more dense than steel. I rather agree. Even if not, if you could consistently fire 400 rounds per minute in a cone in front of this contraption that consistently broke bone on any hit into a crowd charging you, beginning fire at 500 yards... this would do a lot of damage and seriously hurt morale. It'd probably take a lot of rounds to keep it firing though.

And what about evidence?

I love these guys! Thank you, Mythbusters, for the greatest show ever.

[@JonatasAdoM]

I don't get it, if they were not allowed to test cards chips why hasn't anyone on KZbin done it?

[@calumhughes2778]

Damn Tory was proper mad the whole ep haha

43:00 ice cold oh hell no!

[@Logetastic]

If they beat the polygraph, they wouldn't say how to on national TV.

[@Wickedincarnate]

They dont have to polygraphs are not scientifically sound and you should never let one touch your body in the first place.

[@NeekSquad]

The show bullshit did

20:57 leave it to a woman to chicken out from a fake crime

[@mathewdearborn3695]

I thought I've seen every episode but I guess not

[@ohheyitsjoshhinac495]

Fun fact the KGBs lie detector test so so bad if you puckered your butt you could beat it

[@mistermigraine2779]

The polygraph experiment is flawed. The subjects face no real consequences, so, honest or not, they know it is just a game.

[@the_listamin]

45:12 But imagine the horror a weapon of this sort might induce in the opponent that doesn't know but fears it might kill.

[@blankfrankie3747]

I'd be willing to bet the polygrapher had them all pegged before they even took the test.

[@Nikagor]

Yeah the problem being that they knew someone was lieing, meaning at this point their chances for success was that much higher and most likely more based on opinion than facts.

Soo 6x11-15 is 54? :D

Damn Carrie !!! She is steak sauce !!!

[@MLawrenz-w4z]

Fun fact: the guy who "invented" the Polygraph was lying, his wife came up with the idea.

[@hashinta]

Except he didn't get married until after he invented it. Funnily he got married to one of the women that was a suspect in the first case he tested it in. After that case he didn't believe it worked to a high enough accuracy to be used for criminal conviction. It's actually a really interesting story of a well intentioned invention getting twisted into something sinister.
