- Former President Obama challenges Adam and Jamie to revisit the Ancient Death Ray myth! Will it finally work?
Using science as a tool, Hollywood special effects experts attempt to debunk rumours, urban legends and popular myths that have captivated the minds of many individuals.
#MythBusters #FactOrFiction
Obama was like bros can you test this weapon of mass destruction for me
Jamie got the same shirt on even meeting Obama, lmao
Not exactly the same shirt, it's higher quality, and better ironed.
You can't improve perfection.
Yeah, he was maybe a little underdressed ... Obama, that is. But I'm sure his Royal Mustacheness didn't mind much.
Obama was the one who had to dress up to meet Mr Hyneman.
@@AeonLibertas It's only obama, can't take thst guy seriously anyways
I mean, unless the guys on the boat are wearing completely encapsulating clothes, 140 F is planty enough to cause skin burns if applied for more than 5-10 seconds. I imagine it's more the case that the soldiers had burns from focused sunlight, went back and said "It felt like I was on fire" and someone just wrote it down as "ship burned by sun laser"
yeah, according to the net 125°F is enough to cause burns over a 2 minute duration and 130°F in 30s, so a good 140 ~ 150 would burn a person.
Even if they would not get the temperatures that high, i am pretty sure blind people or at least visually impaired people, do not make the best soldiers.
@@mountbuckekreative4044 pretty sure five hundred soldiers with bows and arrows would be more effective than maybe blinding the soldiers of one ship that happened to stand still enough in the water for you to hit it xD
@@MLF4468 Honestly the mirror holders would most likely be women and children during a siege. Although they still might be better served carrying around supplies and ammunition or other defending tasks. And since it was a siege, it's very likely that enemy bows couldn't really quite reach the top of the wall and anyone who got close enough would be screwed up by the defending archers. I'd say it's not an awful idea for some people to try this in a real siege, especially if they've got tons of manpower and perhaps a lack of weapons or ammunition and some creativity
The myth isn't about slow cooking long pork. It's about setting the boats on fire.
I am teenager again after 17 years...good times
I like that Adam has to wear a suit to visit the White House, but Jamie can just stick to his normal outfit.
he didnt have to, he got to. he probably enjoyed dressing somewhat like the secret service. also Jamie is wearing a shirt, his standard outfit is fairly smart as it stands
the editing during the mirror test was on point. Really felt like a scene from some historical-ish action movie. Adam's motivational speaking was also great.
Seeing Adams wearing a Dacian War (102AD) armor in an Archimedes Myth (212 BC) only hurts the heart of a history nerd 314 times
only llike 3 centuries off, not that bad in the big picture but I respect the detail man
I forgot about this, lol. Time when Mr. President appeared on Mythbusters was peak, lol.
13:42 Someone got distracted by Jamie's... pants
Well, that many people with mirrors and zero training? Split them into small groups to get used to finding its own reflected light. I think it requires at least few days of training to aim mirrors precisely.
Half of them wasnt even aiming at the lakes general position xD
@@3604marine True.
The hellboy car flip was a faulty test... a superhuman from hell was planted on the ground not falling and susceptible to loosing downward force when the car hits.
Agreed
Not to mention not forgetting to factor in the presence of comic book grade plot armor
The Hellboy myth wasn't really tested well.
The downward force has nothing to anchor it in place the way hellboy's body does, so as soon as it makes contact with the vehicle it begins to be pushed backwards stopping it from delivering it's full downward force abrubtly.
If they had driven a vehicle into a downward angled fist anchored in place aimed directly at the corner of the bonnet/grill I would guess they would get some degree of lift on the back-end even without any downward force from the punch.
And then what would you do when it doesn’t flip and runs into your rig?
@@kyuofcosmic conclude that the myth is busted and has been tested well. (edit*) actually I'd build another rig that has the fist dropped on a giant lever so that it is anchored in place and delivering downward force, then if it still doesn't flip I'd call it busted :)
@@kyuofcosmic build a second rig that has the fist attached to a lever system that is placed at a right angle from the line which the car passes so that it would have downward momentum and be anchored (think a right angle triangle build of steel with a fist on one of the none 90 degree corners, the rig is built to drop the triangle into a horizontal position so that the corner with the fist makes contact with the car but the triangle shape braces the impact and provides added points that can be secured to stop the rig turning or warping) I would assume the size and strength of the triangle would mean it is plenty resistant to a 30mph misfire and if not it would be a simple enough structure to re-weld and fix, and as it is to the side of the vehicle if it misses completely it will be out of the way and sustain no damage. if the vehicle still doesn't flip I'd call the myth busted. yes there is a chance the rig may still get too damaged too many times before any verdict can be given but that is a common situation on mythbusters. sometimes all you can do is hope everything works and see what the result is.
Was actually about to say this, the fist should have been weighted to more than the car so it would be less likely to move after the impact maybe or like you said have it fixed
There were some experiments on the archimedes solar Ray in UK too, that really managed to damage some stuff. The unintentional test were held at 20 Fenchurch Street in London.
hahahhahahahah totally mate! XD
There must be one of me for every model of car that the Mythbusters destroyed, but those old Cherokees from mid '80s to early 2000s, were amazing vehicles if you get the straight six. I used a '94 with 400000 plus kilometers (250000 plus miles) to pull a small boat from Toronto to Calgary, lived there for a year, then drove it home with the boat. It was over 490000 kilometers (almost 305000 miles) when i got back. I've driven two of them to dust. Those old jeeps saved me so much money. They are amazing vehicles if you take care of them.
When I studied for engineering even long after myth busters had stopped airing, I remember how frequently mythbusters testing a species myth and how they did it just came up regularly in conversation.
We had all seen and grown up with it. And enough that when people would reference specific episodes it was just a given that everyone saw and remembered it.
I guess mythbusters really was a key point for a whole generation if not more of future engineers.
And basically on a global scale, as it was huge show in loads of countries.
Really quite cool when you think of the scale of it.
The problem with the Hellboy myth is nerds have no natural sense of collision physics. Anyone who's played a sport like rugby could have told them the key isn't how hard the punch comes down, but rather how solidly grounded the whole mechanism is. Run into me while I have my boots on the ground and I'll be able to use my core and leg strength to push back. Take my feet off the ground and there's nothing but my mass for resistance. Dropping a weight from above is all but useless for what they were trying to do.
What they needed was a giant version of Grant's battlebot, Deadblow, rooted to the runway with a whooooole buncha those trench plates and swinging its hammer down with Hellboy-like power.
mate it's a superhero who's actually Lucifer with a giant rock hand
we came for that, not for physics
nerds have no sense of physics? do nerds not study physics?
@@ThePurpleCheesecakeZebra Athletes have a natural sense of how to position their bodies for a collision that is far superior to other people. Nerds tend not to be athletes. They completely missed the most important part, which would have been blatantly obvious to anyone who's ever spent much time knocking other people down.
@@scrivener68 Any "nerd" (why don't you grow up?) should be able to tell you your understanding of why it doesn't work is completely flawed. The car is effectively not solid enough, even at the engine block to provide enough resistance to transfer the force of a Hellboy fist into the required flip. this is a pretty good example of why you cannot directly apply your lived experience of athletics to collisions between objects made of different materials and densities in an intuitive way.
Well, I might not know what I'm talking about here... but in the movie the punch also stopped the car. Perhaps transfering it's forward momentum into that flip trajectory.
Here, a weight was simply dropped down on the car without countering, stopping, or otherwise altering much of the energy moving the car forward.
Remember: Hellboy didn't budge at all, but remained static and unaffected by the physics involved in the motion of the car, as opposed to this weight that seemed to travel with the car. In other words; after the "punch", the energy left behind the forward momentum of the car was transfered to the weight.
I think that factor was overlooked.
This "punch" needs more stopping power.
Perhaps striking the car with even more force combined with hitting it diagonally down.
Do you even need forward momentum from the car?
I am pretty sure that I can flip a toy model car by pushing it's hood down using my thumb, and that I could stomp that RC vehicle and make it flip in the same way. My mass makes that of a toy car completely insignificant. You cannot replicate that result in full scale without applying the same variables in physics. In my mind, if the conditions are scaled accordingly, provided the structure of the car won't get comprimized too much, you should be able to flip a full sized car, no problem.
The time is long past that such a response would get them to re-test it (what with one of them no longer with us) let alone the fact the show isn't going still. But stellar response, sometimes their science does be sloppy, but I appreciate that they're transparent about when they fuck up.
Ah the solar ray thingy, I still remember to this day that fans just doesn't want to let go of this, being salty fo no reasons and just let this one go. Good times.
What disappoints the fans is that the kids were morons, shining at anything but the black sun on the sail they had to shine at.
Or concave mirrors? Pretty sure Archimedes would've been more than capable to calculate a focal point
@@danicorvin Adam I think still brings this up. The requirements of the muth specifically mentions flat mirrors
@@TheTrueBatBraindidn't know that. Still feels odd. I was nine when i discovered I could burn holes in the table cloth with my grandma's glasses. Surely Archimedes was many levels above me.
@@danicorvin But it's refraction, not reflection, it passes through the glass and gets focused on a point you can easily aim and concentrate.
The thing about that myth is that in school when I was learning old Greek and Latin, the myth was not that it is to set on fire but to exactly do what they did distract. And make it impossible for the archers to aim properly. But the own archers have it easy to aim. As well as distracting the steering of the vessels so they can get to close together and even hit each other. So actully they have proven the myth, cause in the literature I don’t remember that the boats get set on fire by the sun rays but by archers. But of course it can be that in some ways that was transported through time as the sun ignored the vessels cause with that army of mirrors you probably wouldn’t see a flaming arrow.
Mythbusters forgott one thing. In the time of archimedes, there was no airpolution. Sunrays had much more power. If someone truely wants to check the "Death Ray" he has to go to an area with only a minimum of airpolution.
One of my favorites!
The fact that Jamie was on the boat during the solar array test gave away the fact it was going to fail as a weapon. If they thought, there was a chance the boat would catch fire, do you really think they would have allowed Jamie to be on it?
i mean, he's in water, it if catches fire, he can jump off
@@terrorhuhn9192 say he got trapped on the boat, his clothing got snagged on the rigging or something
@@reviewflicks jetskis with extinguishers
Obama episode. I remember this one when it originally aired
id like to see wither of the last 2 presidents appear on a tv show so casually
I loved that while the car always crashes into the fence but has never reached the end of the runway and into the water
Imagine Trump appearing on Mythbusters asking them about Sharks and batteries and whether they prefer being eaten by sharks or electrocution?
Remember Lord of the Rings, how in sync were the elves?
This needed that, flip and point one mirror at a time and then the soldier holds position. (I guess 1~3 secons to aim and then stand still).
so the beams will be perfect.
The solar ray myth is not busted in my opinion - just hard to replicate. We all know that parabolic BBQs work but scaling it up to take down a warship is just too damn difficult.
I think they should focus the mirrored rays into some sort of lens to enhance the burning power. They could use an antenna dish shape packed with mirrors, focused into a lens. if correctly done, even the dish shape with mirrors alone could be more effective than all of their experiments about this mythical invention.
@@HighExplosiveSerenade Yes I wonder of Freznel lenses in front would do it !!
I'm here for the Hellboy myth.

Was looking for this comment, in all seriousness, there are worse combinations of things
Putting up a black net and then aiming through a white net.
Somebody had to paint that net white.
And indeed they did. Adam told a story about it in one of his QA sessions.
@@Treviath interesting, probably aiming through a white net is easier, as there is more reflection.
Or did the black net took too much of the light on the ship?
A Roman Segway 😂❤😂❤
You know it completely slipped my mind that Obama had a guest appearance in Mythbusters.
I can‘t remember the bronze mirrors they had but what i always thought is, that if you are going to polish your bronze shield to do this, you‘d do that to the inside, right? Because it‘s a slight dish with a fairly far focal point and not an outwardly curved surface that would disperse the light no matter what.
Edit: nvm i just calculated that, a shield that is anywhere remotely normal would have a focal length far below 10 meters. But that also means shields are shit at that job in either orientation 😂
20:20 Well you can theoretically calculate the time needed to release before, but it is very short and there are so many variables like the reaction time of the sensors and electronics, the reaction and release time of the holder etc. It's really not that easy, can't blame them for that 👍
Edit: Ok I got it: You'll need a heavy punch downwards to give it momentum downwards, but then also a second force instantly stopping it. That may work.
Edit 2: And for the solar mirror,they just couldn't focus steady enough. With an apparatus stabilizing each mirror, that ship would easily burn.
They cut so much of Obama out of the UK showing of this episode.
I swear so many of those mirrors were pointing in the strangest of directions. I've gone through boot camp, your mind would be blown with how people can fail at the simplest of tasks
"... occasionally, you blow things up, which is always cool, but, i have a personal interest in this, as a president..." - Obama out of context 2011
What about using concave mirrors to focus the light like a magnifying glass with a focal point somewhere near the distance of the boat? I am sure that Archimedes was smart enough to figure that out instead of using flat mirrors. That would have increased the intensity many-fold as it is all about focussing the energy of the sun over a large area into as small an area as possible.
There were so many awesome collabs, even the president appeared on the show 😂
Now that's Adam from "Tested" -- he actually built on an Ancient Roman chariot facade to his segway.. For a two second shot.
Thanks Obama!
,
Nah
they could have tested with something to catch the weight and the car just passing on the side
The fist shouldn't have been dropped vertically. The car's momentum had to be arrested by the hit, allowing the energy to contribute to the flip. I'm not saying it'd work, just that we wouldn't know without a better setup.
I'd think a pneumatic telescopic arm mounted to a stationary mass. I think the objective would be to punch in the bonnet with enough force to establish a low rotational pivot point below the centre of mass of the car. The downward energy of the punch would add to the rotational energy from the car's momentum. I imagine the car may have to go faster than 30mph and it would be way more destructive than in the movie, but it might work.
The car flip clearly wasn't going to work because they forgot to factor in the magic physics of Hellboy's plot armor. They needed to put an untsoppable object directly behind the impact point anchoring the impact device, clearly.
The driver was likely braking
I think, removing the suspension would have made a world of difference. So much energy goes into compressing those springs and not enough into creating torque.
Here's a small experiment everyone can do. Take a coin. Put it on something rigid with an edge slightly going over. Now smack it with your finger. Then repeat it on something soft.
To figure out if it was possible to flip a car, they should’ve pulled down from the leading edge of the car. Find a concrete pit, big enough to anchor a pulley to the ground inside the pit, but small enough to drive over. Pull the car until it lifts and starts to flip. If it’s possible.
Pulling the car towards the pit, with an open pulley over the pits edge, then when the car passes over the pit, the force is transferred to the anchored pulley, pulling the front end down fast. This would be the best chance at doing it. It provides the forward momentum AND the speed required for the suspension to push back and aid the car flipping.
"we need to keep the youth interested in science"
I think that ship has sailed a long time before that....
The kids absolutely focused on the boat or on Jamie. It's simply shitty coordination and dumb trolling by the kids...
And the net should've been further away, because the spread on it was more distracting than helping them it seemed.
The small test with the net was more focused, because it was a smaller group of people with smaller mirrors, it would be easier to find your beam on that.
Plus it just needed a couple of tries at least, they clearly weren't trained to do this right on the first day.
@@Games_and_Music Very sound analysis! I fully agree!
@@Games_and_Music I mean the most straightforward thing would've been to mark out positions in a parabolic pattern like a satellite dish. Archimedes would've been able to do that, draw a massive parabola, mark positions down to the angle of the mirrors and literally just have people stand there
@@HeavyMetalorRockfan9 That's a good point as well.
They make it sound as if they were freehanding this thing, but it would make more sense to have people take position, rather than aiming it on the fly.
Although the position of the Sun does change, but yeah, it's gradual, not something that suddenly sneaks up on you.
And i'm not entirely sure what exactly they used to aim with, because shouldn't it be fairly easy to track your light if you point it at the ground first and then follow it up towards the boat?
There shouldn't be a whole lot of deflection or depth change if they're just standing on the shore like that.
@@Games_and_Music the beauty of a parabola is that it doesn't matter where the incoming rays are coming from, its focal point is always the same, its why satellite dishes are shaped the way they are (technically they're parabaloids and a parabola is just a slice of a parabaloid, so 2 dimensional)
If the shape was correct they could literally just fix mirrors and any time someone went through it would light them on fire lol
Edit: If they wanted to make a reusable weapon they could make an adjustable tripod style thing
During last car punch test the weight itself has stopped car fripping. Because when it touched the car, it slid to the centre pushing it down
Yeah, and it was released a bit too late as well, it should've hit only the plate, but it partly hit the beams as well, and yeah then slid farther back.
This was a very cringe episode eventually.
@@Games_and_Music Front wheels are the axis of rotation, the weight hit at the very back edge of the plate, making the lever length nearly the same as it would have been on a perfect bumper hit. It looked so stupid when they were making tests on a toy car and hitting the front wheel axis or even behind it, getting it to jump only by suspension rebound. The final test car would have likely flipped were it to be hit on the front edge of the plate.
2:22 nah he 100% got the mythbusters in for that hospital
Nitpicking but...sun moves?
This video is that old😮
You can flip 2cv just by applying the brakes. I've seen it done.
Tiny inboard brake pads on the front wheels only and a rounded hood. Funny to watch.
I’m probably completely wrong but rather than using flat mirrors Could you not use multiple parabolic mirrors with the same focal points all directed towards that focal point to create a (for lack of a better term) super focal point, especially if you arranged all the mirrors in a parabolic configuration.
Using students for this task was a mistake. Even the grownups couldn't do it. The theory is extremely simple, if focused on one spot they could definitely set the boat on fire.

@@satchelgeddon4042 Is this another conspiracy theory?
imagine the rejection mythbusters would've given if trump wanted to be on this
but that's a joke already, thinking he trusts science and objective fact like a regular person
Always remember, if you are too stupid or untrained to do somthing, it means it can't be done at all and the myth is busted.
When they are figuring out how much weight they have to put on the front of the car to make it touch the ground - who says Hellboy punches just with that amount of force? I mean 5000 pounds may be enough to put the front down, but still Hellboy could have a punch of 8000 pounds... or 15000 pounds... who knows?
Yeah, it was based on a wrong assumption from the start.
Clearly Hellboy punched with more force and kept in position, which basically turned him into an immovable object.
They kinda had to make a giant hammer with a ball on the end to ram the car down and be small enough for the car to go over it one way or another.
But yeah, testing that would've been pretty difficult, but wasting 4 cars on faulty assumptions is a bit too lazy.
@@Games_and_Music Yep, even when they use the lever later, for one although they are saying the weight hits exactly where it should it does not, it's mostly the front part of the car again. And the construction they built is mostly stopping the car from flipping because it when the lever hits the bottom it stops the back of the car going up...
@@gordonbrinkmann Yeah i agree, the weight definitely did not hit it "exactly at the right spot" as the narrator claimed and Tory pretended it to be.
The lever might've worked if they pitched it up a bit, kinda like the see-saw that Jamie made to launch the girl in the air.
That way, the weight would have had more time pressing the car down, plus it would've acted like a brake once it hits the ground (simulating Hellboy staying in position), plus it could've helped the plate to hook behind the weight to assist the lever to do its flipping thing.
Because, yeah, they already showed in the small scale test that the rig would've prevented the car from flipping once the plate hits the ground.
I thought it might've been possible, but it would've needed a super accurate shot at it and a perfect hook around the weight, otherwise the car would just stop halfway the flip again.
When Tory was explaining the rig, it did not have the yellow supporting beams on it yet, and i kept saying: "It's gonna collapse the roof!", at least they added the beams, but it was a very wasted episode in the end.
@Games_and_Music
Yes u are right, I am pretty sure they have could pulled it of, even with 3000 pounds or something, the problem was that the car didn't come to a instantaneous stop, therefore the linear motion didn't transfer into rotation.
@@anettemeier5167 Indeed, the weight was added to the car, which basically is the opposite of wanting to let the car fly.
And yeah, because the weight wasn't going straight down on the lever, and in fact moved along with the car, that definitely messed with the instant motion transfer as well.
Jamie's a bit starstruck.
I'm gonna fuckin pre
Anyone else wondering how Trump would have navigated this? 😂
There's something to Obama that I can't explain, you will respect him not as a president but who he is.
that is true🙏🏽 Greetings from Germany

@@UltiMogr Right.
wow, a war criminal special!
hey, cool! Mr the president himself!
Polls of historians and political scientists rank Obama among the upper tier of American presidents. He has been described as one of the most effective campaigners in American history (his 2008 campaign being particularly highlighted) as well as one of the most talented political orators of the 21st century. Historian Julian Zelizer credits Obama with "a keen sense of how the institutions of government work and the ways that his team could design policy proposals." Zeitzer notes Obama's policy successes included the economic stimulus package which ended the Great Recession and the Dodd-Frank financial and consumer protection reforms, as well as the Affordable Care Act.
Ah yes, but what if the shields were polished on the back side? A parabolic mirror. Would`ve loved seeing that.
The problem with parabolic mirrors is that they couldn't be used as an actual weapon. Due to the focal point the target has to to stay at a fixed distance, enemies don't tend to do that.
@@kingcosworth2643 That`s a fair point, however it would be better than a standard flat surface dispersion for which Adam used a net for better aim. Sorry, English isn`t my first language. The ancients did a lot more hard math then us these days, so i believe focal point problem would`ve been solved
I love Obama. Perfect.
Obama is a really nice man. Even though I myself never met the guy, I could just feel that his aura tells me that he has genuine caring heart.
2:28 this hasnt aged well xD
Wish we could have just reelected him. Back then, Reps only argument was racism and nothing crazy. Now both sides are so crazy on their own extreme ends it reached the part where it stopped being funny and it's actually sad.
God i miss the Obama years
Of course Obomber was interested in death rays. I would have thought that they would use mirrors that are curved so as to focus the beams.
Oh look the president wants the myth busters to make a weapon. Who knew.. could have tried to make accesible algae food. Or cleaning air. Or saltwater to drinking water.. nahhh. Let's make a death ray. Ffs
I mean, under his administration, he dropped around 20k bombs, embraced drone programs, and carried out more air strikes than Bush, so why are we surprised 😂
Those aren’t myths. Deep breath; it’s edutainment.

Here’s an experiment showing how you’re emotionally immature far past your age, would you be okay with a show you love and enjoy using a politician you fundamentally disagree with for a cheap cameo? I thought Seth Rogan was the most cringeworthy, but.. wow.
So, this is where a bunch of corporate and governmental bureacratic people start deciding for the mythbusters what they are, and it was terrible ever after this point. I see a pattern.
Bring that black man back to rule
OBAMA, GROSS.
