Somebody should try and blend in with the shadows by using a black cowl. If you want as well they could fully dresses up as batman and try to accomplish the same thing.
As long as mud is wet, it will draw heat from the substrate to dry. So your body heat will actually get wasted on drying the mud, instead of actually heating it. That is why I believe it works so well. That is also why you would constantly feel cold while covered in it.
I suspect even the outer layer of the body would affect it too, like if you just climbed out of a really cold river like Arnie did, the outer layer of your body would also be very cold, so your body would first have to heat up your skin and other extremities, and then dry out the mud before actually fully heating it up.
Also, it was night time in the movie, cold, Dutch was basically shirtless, had been in the water, and was covered in mud which - as stated - would leech heat from the body to dry. That being said, I know it got down to 42° where they filmed (Mexico, mainly) but they were supposed to be in Guatemala which generally doesn't get very cold at night except in the mountains. Still, I have to imagine being wet, covered in mud, and half-undressed at night is going to drop your body temp at least a bit.
@@johnplaysgames3120 not to mention, in Texas, I imagine the heat and humidity(being he said it had just rained) also hinders the performance of all thermal devices so in this situation he was colder than most of his surroundings and worked flawlessly. Had it been at night it would probably not work as good unless fresh.
@@JDGansGaming no, the predators movie had this scenario again. And an alternative vision mode let them see/sense heartbeats. But if they have hounds......
Something to also consider. When Arnold first hides from the predator he has just climbed out of a raging river which most definitely cooled his resting body temperature. Making his thermal signature even more faint. I feel most people don't mention that when talking about this scene.
I think location of South-American damp jungle is even bigger effect. Difference between body heat and enviroment is less and damp air makes heat transfer slower. Temporary dip in surface body temperature is not much and equates real quickly.
The movie mentions the Predator shows up during the hot summers. If the jungle was reaching 90-100 F, then the difference between skin temperature and the environment would be less. And is it just a thermal camera? It was presented that way, but that was also for the viewing audience at the time. Talking about "augmented reality" would have drawn a blank look to most people in the 80s. (This was still years before the WWW was created, let alone the Internet or VR as they are now.) There would be more to it than just temperature. If it was only thermal vision, it would be hard to see where you are walking. Adding a layer clay might have confused the over-optimized computer algorithm that was designed to emphasize flesh and fabrics, and de-emphasize foliage and the general jungle environment.
@@mmattson8947 The Predator definitely sees in the thermal spectrum with its bare eyes (because it's "reptile" like?), although they certainly capitalized on the very new-at-the-time thermal camera tech to portray it in the film. The mask just adds heads up displays, and apparently "dims" the thermal image like sunglasses. When the Predator takes off its mask to confront Arnold face-to-face, we see a POV shot of the predator's vision getting "hotter" as the mask is removed.
as the mud dries the evaporated water cools at the same time it also blocks the body's IR emissions, its the same reason why animals roll on mud to stay cool, as the water evaporates it cools them. however it will stop working as soon as the mud dries and it starts hindering your ability to cool naturally instead. however its important to note that depending on the humidity of the jungle it wouldn't work as well, since the mud would need to absorb more heat to start evaporating.
Old guy here. I saw this movie in the theater the day after my bother passed away. I saw it 3 times that week, as a sort of get away from my grief. However, I clearly remember thinking every time I saw the movie "that's not going to work". Wow, I was wrong! Thanks guys, this was an excellent video.
I LOVE that someone used the ACTUAL name for the Predators, the Yautja is ever rarely said unless it's deep analysis of the franchises. This made my night!
I gotta say, I hate that is the supposed actual name of the Predators. It sounds nothing like their vocalisations in the movie and looks just like a generic fantasy/sci-fi name. No consideration for how they were depicted on screen.
I think these experiment/Mythbusters style videos are some of my favorites that you guys make. I love all the VFX stuff but testing these seeming ridiculous ideas from movies is so interesting to watch!
@@ez230z I think he simply meant they knew to look for Jake from a specific area. The opposite would be just giving thermals to someone, tell them to walk around, and see if they notice anything.
Mud is known to be used by spec ops units like in Vietnam war when Vietnamese VC and NVN special force lie down in mud for days to avoid dogs and thermal visions. Another way is climbing up very tall trees with a lot of leaves and branches so they block the thermal vision naturally. The later is specifically used by US trained “Rambo” units to spot armies moving inside the forest.
This makes me wonder if they tested this with thermals in the movie or if it was a lucky guess.... especially considering that modern thermal optics was in it's infancy. The effectiveness of a simple layer of mud to defeat high end modern thermals is mind blowing.
Modern thermals aren't defeated by mud at all. They're just using cheap thermals with low contrast. Police or military grade thermals would even be able to block everything out in a certain temperature range. For example, anything above or below 90-100 degrees could be made to appear completely white or black. That would be enough to make any person, even wearing mud, stick out like a sore thumb, and remove most of the unimportant distracting details from the environment.
Also, another thing to take into account when recreating tests like these, Predator take place in a Central American (heavily implied to be Guatemalan) Jungle, where the temps average 80-90F(26-32.22 Celsius) during the warm months, which would also make it harder for the ambient heat to be filtered out and pinpoint the body heat of a human. Add to that the Yautja code of honor that caused Savage/The Jungle Hunter to discard his mask made it even harder for him to differentiate the temps (Considering the mask works like a kind of night vision enhancement would for us, essentially he's fighting in like, dim light at best), it would have been even harder for the predator to see Dutch.
Exactly. They did fake the thermal images for the movie, and they did it because the jungle was hotter than body temperature. The only thing that Predator got wrong about it is that at those temperatures, you don't even need the mud.
IDK bout the current canon, but it was filmed in Guatemala and said to be so in Predators. IIRC the first dark horse Predator comic had it to be in Colombia.
Brandon Herrera?! DONUT?! A Predator thermal experiment that actually worked?? I thought this episode was gonna be OK, but it's the best thing on the internet today. 👏 👏 👏
I always knew this was true when I saw the predator in the 90s when I was 8-9 , I’m from India and we have a lot of things made with mud like plates, jugs, homes and everything and let me tell you mud house will cool you in the summer and trap enough heat inside your homes when winter, we use water containers made with mud to chill hot/warm water because we didn’t have refrigerator. So I knew mud had that kind of heat conducting properties even when it’s not wet. I think a lot of asian countries had this knowledge like Vietnam. And I think the movie makers had some veterans of Vietnam(because thermal vision was widely used during the Vietnam war) consulting them. Awesome video
The US Army didn't use thermal vision in the Vietnam War, what they widely used was the AN/PVS -2 night vision scope. I'm not sure if you really need to cover yourself in mud to hide from night vision
@@QargZer I remember being surprised.. a perfectly clear, spotlessly clean glass window pane, where your naked eye can clearly see the well-lit room and dudes behind it, instead looks like a mirror in the thermal imager. Can only see a reflection of the same side in IR. Cannot spot even the faintest trace of anyone/anything behind the glass. After thinking about it it makes sense, but surprising in that moment.
so to really replicate this experiment you need to to to the Amazon, South America...? Or do it in a greenhouse or something else that simulates the wet, hot, humid conditions.
When you think about it, it makes sense - Jake is a Texas boy, Demo ranch last video has Corridor’s logo on the wall at the merch building, they all have to know each other!
@@tearstoneactual9773 Funny enough fat would work even better. It would cool down way faster than much more blood circulated muscle mass and be an insulator.
@@tearstoneactual9773 Body fat is cold, muscle is hot. In the case of hiding from thermal with mud, being fatter would be a boon all around, you'd insulate your own heat, cool the mud slower, and have more leeway for hypothermia. Like a blubbery seal.
To be truly accurate that mud needed to be on the bank of a shaded jungle stream. The water was likely very cool and therefore so was the mud. And the mud in the movie was thicker. Lastly the predator didn’t stand there and scan over and over for a long time. It took one quick pass where there was a lot more debris to break up the outline of Arnold. So hell yeah this would work.
Hell yeah. Brandon Herrera, Donut Operator, Crispy, and Eli DoubleTap! We need more videos of Jake doing crazy stuff in Texas with these guys. And more videos with Dale please 🐖
Dude, I honestly cannot believe how well that worked. If he would have ditched the clothes in a different area and then covered up I wonder if the dog would have found him?
Same. But I bet the dog would have found him based on that Mark Rober video where he hid from the dog using lots of techniques, and it still found him. 😁
A real search dog works in tandem with a handler. If the dog was fooled by discarded clothes the handler would simply move on to the next scent signature.
Mark Rober did a video about this some months ago and he showed that a well trained dog can follow someone even with a lot of "noise" scent, even when wearing a complete closed suit if you touched the exterior of the suit or had the suit in your bag it is enough for the dog to find you
If the dog wants to find a person it knows, the dog is going to find the person once it gets that close. He is still breathing. His scent is all over every place he has passed. With enough timethat will change, but it takes hours, not seconds.
He made a video with I DID A THING were they put a mg on a robot dog and put a "anti-gun" message in it without telling him. But that's not what bothered Brandon. THEY placed chidrens cardboard cut out as target and said that it was his idea and that Brandon was unphased by it. I like IDAT but it really was a shitty thing to do. @@sojourner.
They've actually known Harley for a good long time. He even played the Heavy in their old NERF Team Fortress video! I can't remember in what video, but I also recall them going to his place and cooking during a behind the scenes shoot for another of their projects several years ago.
I'm surprised people didn't think it would work. Mud is a fantastic thermal insulator; it is used in jewellery and smithing to mask off parts of your work in tempering and annealing processes where a piece is often under direct flames.
@jordytoke2908 I’m not. I’m fairly old and I’ve looked through modern thermals. If I ever have the money I’d love a thermal scope on my AR15. But I also know how thermals were way back when it was just prototype military gear. There’s a reason it looks so janky as an fx in Predator. It was sci fi level stuff back then. Now it’s refined enough to cost less than $10,000 that the rich kid can afford as a hunting scope. Bathing in mud is kind of genius but not something you might thing would really outwit actual retired veterans with actual nice FLIRs. Because it used to be a spec forces/CIA thing you gave the some elite high level shit back in the Cold War.
That's freaking awesome! I love that it works both under thermal, as well as regular vision. The Apache used to use mud to camouflage themselves as well as mask their scent from the animals they hunted. They used to legit sneak up on deer with mud on.
I love that there was this collab that I wouldn't have guessed to happen. Watching two different style channels come together for a mutual thing is awesome
it's actually nuts how no matter how much money goes into camouflage development and body armor; nothing beats state-of-the-art warfighting equipment better than good ol' dirt and water.
The difference is, camouflage has to work for hours, maybe days. Mud will dry out and warm up after some time and would be terrible for your health if you're already in a cold and very wet climate.
@@freedomloverusa3030Except that you’ll leave footprints in mud, which allows your adversaries to track you better. So you should probably avoid getting mud from the same place twice.
Guys. True. Part 2 please at night. Make it a bounty. Let em use drones heatvision etc. find three of you using different methods of concealment in movies , the ice bath in minority report etc
They couldn't find him in daylight without the help of a dog. At night their chances of seeing him would be even worse but the dog could still smell him just as easy as before. So I'd expect the same result.
@@megapro125 when the body heat and day time temperature almost equal its very hard to find him but the night time temperature decrease 10 celcius so they have more chance to identify the body because of the heat near objects are lower than him
You really can't beat the power of evaporation, which is what's going on here. You'd think he'd simply heat up the mud, but the water in the mud turning to water vapor cancels that all out. EDIT: Also what's funny is, they already did this experiment... in the film Predator. I looked it up; they used a real IR camera for many of the shots. It wasn't just some special effect. lol
I don't think that's what makes the difference. I'm no expert but thermal cameras are highly affected by what's called "emissivity". in simple terms, the higher the emissivity of an object, the easier it is to accurately measure its temperature with a thermal camera. mud has a lower emissivity than the human skin. low enough that we get the camouflage effect. so it's not all about just raw temperature
@@MrKrawby and temperature changes the emissivity of a material, so what are u trying to say man. homeboy is right about the evaporation in this case, not to mention the uniformity of the mud covering whereas on human skin there is gradients in temperature at diff body parts making it stand out.
@@MrKrawby In order for that to be true, mud would need to have a very low IR emissivity, like a polished metal. But if you look at an emissivity table, "soil saturated with water" has the same IR emissivity value as "skin" at 0.95. The reason that mud works so well is because it's simply cool to the touch - when it's wet - due to the evaporative effect.
In fact - it makes me wonder - WHY didn't Adam and Jaime - or anyone on that crew, really - think to test this as one of the myths? My bet is - someone did - but it was far enough down the list that they just couldn't get to it by the time the show wrapped up.
@@logandarklighter Or maybe, They already know that its not a myth? Mud is a really good thermal insulator that people already use to be protected from heat.
@@logandarklighter I remember they did, and if I remember right, they busted it because in their test, their body warmed the mud up. They couldn’t apply the mud fast enough before it became visible. I don’t know what’s different from this test vs theirs, but that’s what I remember.
@@milkduds1001 Probably the type of mud and the conditions. Ambient temperature, humidity, day vs night, duration of the person covered in mud, clothing, water level of the mud, all of it could be a factor.
That’s awesome, for years I thought there’s no way mud would’ve worked to mask heat like the movie. I now even more appreciation for Predator. A movie ahead of its time!
I would’ve brought a loud Bluetooth speaker and played predator clicking sound effects while searching for him. Just to make him feel a littlemore immersed.❤
This I think is the most impressive one to me. I thought the same as you guys, that you'd need WAY more mud, like just sloughing off of you amount of mud, and the fact that it only takes that much to completely fool a thermal camera is NUTS!
I dont know if this is relevant, but in the movie, he was in cold water for a few minutes before being covered in mud, in a typical waterfall, water temperatures are very low and would have cooled down his body temperature for a bit, then the added mud, would have increased that body temperature drop. But you are right, it would not have covered his heat signature after the mud was starting to dry.
Wow… I had to do a double take when Harley from Epicmealtime showed up. After the insane punishment that guy put his body through, I cannot believe he is still alive.
I think they made a very important point when scanning for him in separating what they know and what they see. They already know where Jake is because they set the shot up to get a clear result, but they ignore that to see how the Predator would parse the visuals. Too many would work backwards and find signs instead of using them. The IR scope seeing his eyes being an example. He knows that's a sign because he knows Jake is there, but he also looks at the whole scene to know it wouldn't be enough to key in on. It's similar to knowing Clark Kent is Suoerman. You're seeing the dots to connect because you already know.
Well, the eyes and mouth are a pretty strong pattern to recognize... and considering how thermals are the Predators primary mediod to observing humans, it would be something they could spot as a sign.
@@RipOffProductionsLLC Eyes and mouths are only good patterns when you know they're there. Otherwise, they just look like holes. Especially if there aren't enough defining features surrounding them to suggest a face.
@@bryanwoods3373predator is an alien though, with tech to cross the stars. We are centuries behind any thermal and target acquisition technology predator would have. Predator could also see in different / more frequencies than we do, and we wouldn’t be able to know because we can’t see it, and thus we probably would stick out like a sore thumb (though that wouldn’t make for an intense action movie so they nerfed the aliens).
@@It-b-Blair And yet the movie establishes that the tech can be beaten this way. It doesn't matter what a real advanced society can do, just what this fake one is shown using.
@@bryanwoods3373I think you are both correct to some extent, but eyes and mouths are instantly recognizable features; to the effect that people see faces in things where they clearly don't exist, such as the moon, Mars, or on toast.
Awesome. Now test the opposite. In Predators, the last surviving protagonist subverts the original movie by surrounding himself with a bunch of fires to overload the Predator's thermal vision instead. I doubt it'll work anywhere near as well, but I'd still like to see it tested.
It should depend on the delta (difference in temperatures) but it would be interesting to see how the ir sensor and software process the difference of hundreds of degrees in the surrounding air versus the ~100 degree body temp of a human lol
Maybe you can try the "urban camouflage" from sherlock holmes: a game of shadows (or maybe other films as well) You basically have a costume with the pattern of the wall behind you and you try to hide in plane sight
MythBusters tried this and concluded it failed, but only because they tried this in a building, and even though it worked at first and the guy wasn't detected, the mud dried and it stopped working. I said to myself if they had tried it in wet mud outside in moderately cool temps, it would have worked just like in the movie. The jungles are known for being very cold at night and even sometimes during the day under heavy foliage. Arnold even had a bout of mild Hypothermia because they were not expecting the jungles to get so cold. They had all the actors covered head to toe in insulation wrap. Bill Duke fell severely ill and consequently was in bed rest for days, shivering even under a pile of blankets. Like peoples perception of deserts, it's not always hot and temps can swing wildly under various conditions.
Exactly this ! People underestimate how cold a jungle can get it's always wet there even if you are in the dead of summer you will still feel chill in the night
Wow you just made the movies so much more believable! I always had a base level of doubt that there'd be heat showing through the eyes or something, I dunno.
We did saw that heat showed through the eyes, in both the color version and the black and white version, but this was with them knowing where he was and filming him directly, if you didn't know where he was, and you saw that small bit of heat, you would never say that was a full grown human, perhaps a rat or some other small animal being there.
@@RexZShadowyeah any type of noise will do. bc I don’t know if plants have any sort of heat that registers. Probably contours of heat-exposed vs shadowy parts.
That's amazing. And even that thermal imaging that the police helicopters and military use could barely make you out. I think if you'd closed your eyes there, or just had a bit more mud and squinted a bit, there would barely be anything to spot. Wicked stuff. Predator and Predator 2 are both timeless gems!
Would of been an awesome fact but he wasn't, Jake was originally and still kinda is a lawyer and does alot of the background paper work and legal stuff at corridor plus like producer stuff awesome skill set. Whether he lends his expertise to other UA-camrs I don't know buttttt I do know that corridor have known Harley for a long while and the people who live in Texas usually hang out often so Jake being in Texas as his main base I imagine he gets invited to some of the guntuber party's etc I've seen clips of him at bradons shooting days I'm pretty sure!
@@HarleyMorensteinweren't you also in some of the Node videos back in the day? And IIRC I thought Sam and Niko made an appearance on Epic Meal Time too right? Or was that Freddie?
Without watching the video, I can tell you that this works. My information is based on an experience Hog hunting near Brackettville and Spofford, Texas. I was hunting and tracking a hog on foot and my rifle at hand was a bolt action .257 Roberts. On the rifle was a thermal scope. I’ve used the scope numerous times, both day and night modes. Needless to say, I felt confident using the scope. The event occurred at night, for those who may want to know that detail. I stopped using the light for a while because I didn’t want to push the hog further than I wanted it. When I looked into the scope I could not see the pig. I knew what it looked like and the fact it was covered in mud was what let me know he came from the pond not far from the HQ. So I looked into the scope and could not see the heat signature of the hog. I did finally find it, but only because he was moving, and all I barely saw was his silhouette. I was not able to get the kill, as by the time I saw the pig, he was already in the thick of the brush. There was no trace of body heat whatsoever. The pig was obviously smart, but not for the “4th-wall” reason that would be a good joke, but because it was the heat of the summer and the mud was used to cool the pig down. It just happened to have worked for the thermal scope that was being used at the time.
I think it's also worth noting that in the movie, Arnold doesn't *have* to know it relies on heat vision for it to be an effective tactic...because mud masks multiple factors, temperature, color, smell... Also in the movie, Arnold is careful to be as still as possible when the predator is looking his direction and when he does move, it's from one hiding spot to another...again decreasing his visibility.
One day Jake is gonna walk into the office disguised as Clark kent, get someone’s attention, disappear like Batman, then everyone looks for him with thermal cameras but can’t find him because he’s covered himself in mud. When they finally find him they chase him outside to the street, where he disappears like Jason Bourne.
My theory of why it works is because the mud is wet. When the wind blows across the mud it evaporates the water in the mud keeping the outside layer of the mud cool enough to be around the same temperature of the ambient air. If the mud were to dry completely I think you would be able to see him with the thermals.
I had the same reasoning as Brandon. I thought the body heat would eventually heat up the mud too much to be effective. Been wondering about this for a while. Great idea to test it.
Well, it will eventually do either that or cool the body down too much to be safe for the person, it is actually a thing that has been discovered in Ukraine since they are using thermal camouflage too
I love that they had fun with this, too lol. Definitely, a success. The only asterisk is that he had to apply a thicker coat of mud than what Arnold's character used but not that much more really. Other than that, the mud probably has to be fairly wet and not be on too long to get too dry.
We see at the end when they find him that his body was significantly hotter than the branches around him. But that's because he'd been sitting in one spot without new mud application for long enough. Admittedly, I think part of why the thermal cameras couldn't catch him is because of how much foliage he was under. The Thermal Cameras just don't have the same level of resolution and focus as a human eye.
They should have done this at night, when his body heat would be much higher than the surrounding terrain. Those infrared scopes work because they pick up differences in heat, and during the day the ground is radiating a lot more heat. I really don't know if it would have been clearer, but I think it would have been more accurate in trying to recreate that scene.
Veritasium uploaded a 25 minute video on termal/night vision yesterday which was heavily informative and entertaining, and now day later this drops. Great timing, both videos are excellent!
You probably can't test this one, but I always wondered if you really could get an 1885 locomotive up to 88 miles per hour as in Back to the Future Part III.
As I remember from playing with one of the cheapest thermal cameras ($200 SeekThermal or something), it was only good at detecting living creatures on a cloudy days - on a sunny day, even if it's actually quite cold outside, the sun would heat a lot of surfaces and I wouldn't detect a dog on the road or a pigeon in front of a tree, because both the road and the tree would be quite warm. I didn't try it in tropical jungle, though, and nobody was covered in mud.
What'd be really cool to see would be to cover jake up in fresh mud, sit him in a chair, and record him with a thermal camera to see how long it takes the mud to stop being an effective heat sink. My guess is that there are two mechanisms at play. The first is the clay content of the mud: clay requires a fairly large amount of energy to shift its temperature (which is why it is used for thermal insulation, like coffee mugs). it will eventually heat up enough to radiate in the same spectrum/intensity as a human body, but it's not going to be instantaneous. The second is going to be active cooling from the water content of the mud. Water is also a great thermal sink, and it also evaporates very easily and carries that heat energy away. I think that, given enough time, environmental heat, or airflow, the water will evaporate, leaving just the clay content of the mud behind, which will then begin to heat up and become visible to the thermal camera.
I think they didn't want to alienate some of the audience: make them stay because they are hooked with the idea of the test, even if they hate Brandon and he happens to be on the video. I myself love Brandon, mostly because of his personality: not a huge fan of his political compass, but we can agree to disagree.
Yes. It's basically turning heat radiation, which the thermals are calibrated to pick up on, into heat convection. The body heat instead of shooting out straight into camera lens at the frequency the camera is designed to pick up, instead gets trapped in the water molecules and lifted up into the air. Thermal cameras of this type are deliberately designed to cut out the portion of the spectrum where heat convection would be visible, because otherwise just your breath would pollute and wash out the picture. And that's why it works so well - it's using the camera's design against itself. If they had an industrial camera designed to pick up on convection, he would stand out like a steaming sore thumb.
I always kept on reminding this particular scene and wondered why the Predator could not see his EYES,....one of the most glowing items in a human body, but not covered with mud and directly looking at the Predator.
Of course it works - but only for a very limited amount of time. You become visible once the body heat has dried and warmed up the mud. For this to work continuously you have to keep the mud wet.
Spolier Alert: Oh my god. This is like the mythbusters episode where they tested if elephants are afraid of mice and everybody was flabbergasted. Good job boys, what a video!!!
I was getting annoyed when they kept saying "the mud will heat up". I'm not even an outdoors person and I know as long as the mud is wet any heat your body gives off. Will be evaporate so the only thing that happens is the mud gets dryer and your body gets colder.
Great Video! Quick suggestion: You should have or could have also make a without mud hide and seek to see how GOOD thermal camera are, then show off how easy it is to beat them or explain why is happens on a more sciency approach.
I was also not expecting these results. I would like to see this revisited at some point. What kind of mud is the best? What happens if you try to run covered in mud? Can you use mud to conceal other things like a car? Maybe a internal combustion makes too much heat to mask but a small electrical vehicle could be concealed fairly well? What about ground based drones or electrical observation equipment?

As long as mud is wet, it will draw heat from the substrate to dry. So your body heat will actually get wasted on drying the mud, instead of actually heating it. That is why I believe it works so well. That is also why you would constantly feel cold while covered in it.
I suspect even the outer layer of the body would affect it too, like if you just climbed out of a really cold river like Arnie did, the outer layer of your body would also be very cold, so your body would first have to heat up your skin and other extremities, and then dry out the mud before actually fully heating it up.
Yes and no, water has a really high thermal energy ratio. So it takes an immense amount of energy to heat up.
Also, it was night time in the movie, cold, Dutch was basically shirtless, had been in the water, and was covered in mud which - as stated - would leech heat from the body to dry. That being said, I know it got down to 42° where they filmed (Mexico, mainly) but they were supposed to be in Guatemala which generally doesn't get very cold at night except in the mountains. Still, I have to imagine being wet, covered in mud, and half-undressed at night is going to drop your body temp at least a bit.
What I wish they would have tested is how long it would have taken for the body heat to penetrate the mud. Any idea?
@@johnplaysgames3120 not to mention, in Texas, I imagine the heat and humidity(being he said it had just rained) also hinders the performance of all thermal devices so in this situation he was colder than most of his surroundings and worked flawlessly.

That's actually nuts that almost a dozen people, and 4 thermals could not find him immediately, and the dog needed to find him
So the conclusion is that the Yuatjas need to start hunting with their version of hounds?

Yeah, that line made me laugh out loud.
on point description
Something to also consider. When Arnold first hides from the predator he has just climbed out of a raging river which most definitely cooled his resting body temperature. Making his thermal signature even more faint. I feel most people don't mention that when talking about this scene.
I think location of South-American damp jungle is even bigger effect. Difference between body heat and enviroment is less and damp air makes heat transfer slower. Temporary dip in surface body temperature is not much and equates real quickly.
The movie mentions the Predator shows up during the hot summers. If the jungle was reaching 90-100 F, then the difference between skin temperature and the environment would be less.
And is it just a thermal camera? It was presented that way, but that was also for the viewing audience at the time. Talking about "augmented reality" would have drawn a blank look to most people in the 80s. (This was still years before the WWW was created, let alone the Internet or VR as they are now.)
There would be more to it than just temperature. If it was only thermal vision, it would be hard to see where you are walking.
Adding a layer clay might have confused the over-optimized computer algorithm that was designed to emphasize flesh and fabrics, and de-emphasize foliage and the general jungle environment.
@@mmattson8947 The Predator definitely sees in the thermal spectrum with its bare eyes (because it's "reptile" like?), although they certainly capitalized on the very new-at-the-time thermal camera tech to portray it in the film. The mask just adds heads up displays, and apparently "dims" the thermal image like sunglasses. When the Predator takes off its mask to confront Arnold face-to-face, we see a POV shot of the predator's vision getting "hotter" as the mask is removed.
as the mud dries the evaporated water cools at the same time it also blocks the body's IR emissions, its the same reason why animals roll on mud to stay cool, as the water evaporates it cools them. however it will stop working as soon as the mud dries and it starts hindering your ability to cool naturally instead. however its important to note that depending on the humidity of the jungle it wouldn't work as well, since the mud would need to absorb more heat to start evaporating.
What about ( WAR ) THE BOLLYWOOD GREATEST MOVIE from YRF universe
Old guy here. I saw this movie in the theater the day after my bother passed away. I saw it 3 times that week, as a sort of get away from my grief. However, I clearly remember thinking every time I saw the movie "that's not going to work". Wow, I was wrong! Thanks guys, this was an excellent video.
I never expect anything but the highest level of scientific accuracy from an Arnold movie
The fact that ironically came true via this test is just the cherry on top.
Maybe now is not the best idea to say something like that.
Who knows when will AI get access to nukes?
Lol, maybe they did research it before adding it to the movie script.
@@Billy-bc8pknot really since they used thermal cameras while filming predator so they knew what they were doing..
I fear, good sir, that you are bound for disappointment. 😢😢
It's bizarre seeing Donut and Brandon collabing with people I never thought in a million years they would collab with.
Ikr dude. Never thought these guys would meet😂
Mutual love of predator
Eli has been friends with Corridor for over a decade. They did a commercial for BRCC. It's not that much of a stretch...
Small world. Not personally a fan of those two, but it's all good.
Now I’m waiting for Brandon to end up on Good Mythical Morning somehow
I LOVE that someone used the ACTUAL name for the Predators, the Yautja is ever rarely said unless it's deep analysis of the franchises. This made my night!
Is it pronounced “yee-aut-ja” or just “Yacht-ja”?
yes, its like "yaa uut tjaa" or " yaa u cha"
I use their real name, but I always have to follow it up with "the predator" because I usually catch blank stares...
I gotta say, I hate that is the supposed actual name of the Predators. It sounds nothing like their vocalisations in the movie and looks just like a generic fantasy/sci-fi name. No consideration for how they were depicted on screen.
what about "Hish-qu-Ten" or just "Hish"?
I think these experiment/Mythbusters style videos are some of my favorites that you guys make. I love all the VFX stuff but testing these seeming ridiculous ideas from movies is so interesting to watch!
Mrs Doubtfire next!
Yea... but the premise is false. Predator anatomy is not equal to human anatomy.
I mean yea, it's movie stuff, it'd be weird if they were also considered humans. Either way the main point was to have a thermal vs mud test@@palasta
should have teamed up with Adam from Mybusters/Tested channel. I don't know Mybusters actually ever did this one on their show.
I love that you got a bunch of guys who knew what they were doing and Jake totally hid from them anyways. So entertaining 😂
I doubt they knew what they were doing...
@@ez230z I think he simply meant they knew to look for Jake from a specific area. The opposite would be just giving thermals to someone, tell them to walk around, and see if they notice anything.
@@ez230z A group of ex military and police, who hunt regularly with the thermals they own, would definitely know what they are doing.
Mud is known to be used by spec ops units like in Vietnam war when Vietnamese VC and NVN special force lie down in mud for days to avoid dogs and thermal visions. Another way is climbing up very tall trees with a lot of leaves and branches so they block the thermal vision naturally. The later is specifically used by US trained “Rambo” units to spot armies moving inside the forest.
@dirtyponcho3694this was about hiding from the predator, not escaping a military manhunt.
Bunch of UA-camrs I've been watching for YEARS but NEVER thought they'd colab. This is awesome
It's so cute how the animals greet Jake all excitedly.
We need more Dale Bacon content. Fly him out to the studio for a day
Pig rolls up all excited like "I heard yall were makin MUD out here?"
don't call them like that they work with him its the crew
@@Eysc ?
Timestamp?
This must have been so much fun for Jake. Hiding in plain sight is his thing. Even Drax couldn’t detect him.
They gotta test the Drax tactic next! 🤣🤣
@@Dashmaster305 I don’t think it works that way, but - to be honest - Jake might pull it off.
This makes me wonder if they tested this with thermals in the movie or if it was a lucky guess.... especially considering that modern thermal optics was in it's infancy. The effectiveness of a simple layer of mud to defeat high end modern thermals is mind blowing.
When they tested the thermal it wouldn't work properly after a while in the jungle because everyone blended in, they had to cool the camera down.
Try to outdo nature, you always fail
Now a days. They use is cold mud ,Thermal waters or a piece of metal paper
The interview with John McTiernan he did mention that they consulted an "expert". The other weakness of thermals and IR is glass and acrylics.
Modern thermals aren't defeated by mud at all. They're just using cheap thermals with low contrast. Police or military grade thermals would even be able to block everything out in a certain temperature range. For example, anything above or below 90-100 degrees could be made to appear completely white or black. That would be enough to make any person, even wearing mud, stick out like a sore thumb, and remove most of the unimportant distracting details from the environment.
Also, another thing to take into account when recreating tests like these, Predator take place in a Central American (heavily implied to be Guatemalan) Jungle, where the temps average 80-90F(26-32.22 Celsius) during the warm months, which would also make it harder for the ambient heat to be filtered out and pinpoint the body heat of a human. Add to that the Yautja code of honor that caused Savage/The Jungle Hunter to discard his mask made it even harder for him to differentiate the temps (Considering the mask works like a kind of night vision enhancement would for us, essentially he's fighting in like, dim light at best), it would have been even harder for the predator to see Dutch.
And then you add to it that Dutch had just come out of the water which would have lowered his body temp.
It's amazing but thanks to modern tech and testing it basically proves that Predator was far better written than any of us had originally thought.
Exactly. They did fake the thermal images for the movie, and they did it because the jungle was hotter than body temperature. The only thing that Predator got wrong about it is that at those temperatures, you don't even need the mud.
IDK bout the current canon, but it was filmed in Guatemala and said to be so in Predators.
IIRC the first dark horse Predator comic had it to be in Colombia.
@kittentacticalwarfare1140
It was filmed in Mexico.
Brandon Herrera?! DONUT?! A Predator thermal experiment that actually worked?? I thought this episode was gonna be OK, but it's the best thing on the internet today. 👏 👏 👏
I always knew this was true when I saw the predator in the 90s when I was 8-9 , I’m from India and we have a lot of things made with mud like plates, jugs, homes and everything and let me tell you mud house will cool you in the summer and trap enough heat inside your homes when winter, we use water containers made with mud to chill hot/warm water because we didn’t have refrigerator. So I knew mud had that kind of heat conducting properties even when it’s not wet. I think a lot of asian countries had this knowledge like Vietnam. And I think the movie makers had some veterans of Vietnam(because thermal vision was widely used during the Vietnam war) consulting them. Awesome video
The US Army didn't use thermal vision in the Vietnam War, what they widely used was the AN/PVS -2 night vision scope. I'm not sure if you really need to cover yourself in mud to hide from night vision
Corridor in just one episode managed to destroy years of criticism from all movie reaction channels on youtube! Great work 👏👏
Literally though. No one else actually went and tried it. They just thought it was dumb.
@@Drrobverjones glass and other transparent materials also block thermal from working
@@QargZer I remember being surprised.. a perfectly clear, spotlessly clean glass window pane, where your naked eye can clearly see the well-lit room and dudes behind it, instead looks like a mirror in the thermal imager.
Can only see a reflection of the same side in IR. Cannot spot even the faintest trace of anyone/anything behind the glass.
After thinking about it it makes sense, but surprising in that moment.
so to really replicate this experiment you need to to to the Amazon, South America...? Or do it in a greenhouse or something else that simulates the wet, hot, humid conditions.
@@andrewmurray1550 I'm guessing you have never been in the south of USA before... Texas is a similar temperature and humidity as the Amazon
This is such an unexpected yet very appreciated crossover
When you watch channel making VFX and sudenly your favorite guntuber comes in 😀That was sooooo unexpected :o
I know! I did not expect the Epic Meal Time crossover
When you think about it, it makes sense - Jake is a Texas boy, Demo ranch last video has Corridor’s logo on the wall at the merch building, they all have to know each other!
I wasn't expecting to see a future Congressman in this video.
The dirtiest episode yet
Movie Thermals:
“3 walls and a Kitchen sink, I can see the guy walking perfectly”.
Real life Thermals:
“One thin layer of mud, almost invisible”.
Also when they were filming the mud scene, it gets REALLY cold from swamp cooling in the jungle area. Arnold was borderline hypothermic doing the mud
Arnie also had very little body fat, so that probably was a big factor.
In Predators, Adrian Brody even has torches nearby as a distraction.
@@tearstoneactual9773 Funny enough fat would work even better. It would cool down way faster than much more blood circulated muscle mass and be an insulator.
@@tearstoneactual9773 Body fat is cold, muscle is hot. In the case of hiding from thermal with mud, being fatter would be a boon all around, you'd insulate your own heat, cool the mud slower, and have more leeway for hypothermia. Like a blubbery seal.
To be truly accurate that mud needed to be on the bank of a shaded jungle stream. The water was likely very cool and therefore so was the mud. And the mud in the movie was thicker. Lastly the predator didn’t stand there and scan over and over for a long time. It took one quick pass where there was a lot more debris to break up the outline of Arnold. So hell yeah this would work.
The Corridor/Brandon special was something I didnt realize I wanted more of
Hell yeah. Brandon Herrera, Donut Operator, Crispy, and Eli DoubleTap!
We need more videos of Jake doing crazy stuff in Texas with these guys.
And more videos with Dale please 🐖
YES PLEEESE!
And even wearing Fat Electrician merch too. I love this community.
Dude, I honestly cannot believe how well that worked. If he would have ditched the clothes in a different area and then covered up I wonder if the dog would have found him?
Same. But I bet the dog would have found him based on that Mark Rober video where he hid from the dog using lots of techniques, and it still found him. 😁
A real search dog works in tandem with a handler. If the dog was fooled by discarded clothes the handler would simply move on to the next scent signature.
Mark Rober did a video about this some months ago and he showed that a well trained dog can follow someone even with a lot of "noise" scent, even when wearing a complete closed suit if you touched the exterior of the suit or had the suit in your bag it is enough for the dog to find you
If the dog wants to find a person it knows, the dog is going to find the person once it gets that close. He is still breathing. His scent is all over every place he has passed. With enough timethat will change, but it takes hours, not seconds.
tl;dr
That is amazing and great work guys! Awesome having the other guys like Brandon and Crispy and other military guys here help with that
Seeing people outside the gun community collab with brandon without shitting on him behind his back in the final product is nice.
Like ididathing did
Agreed
Corridor Crew has done Collabs with Matt Best and Black Rifle Coffee couple years ago
That happened? Why?
He made a video with I DID A THING were they put a mg on a robot dog and put a "anti-gun" message in it without telling him. But that's not what bothered Brandon.
THEY placed chidrens cardboard cut out as target and said that it was his idea and that Brandon was unphased by it. I like IDAT but it really was a shitty thing to do. @@sojourner.
I didn't expect Donut and Brandon to show up lmfao
o.O saw Eli with the thermal at the start and just read this comment. Hyped now.
i didnt expect Harley lol
I didn't expect Dale
Don't forget Crispy
They've actually known Harley for a good long time. He even played the Heavy in their old NERF Team Fortress video! I can't remember in what video, but I also recall them going to his place and cooking during a behind the scenes shoot for another of their projects several years ago.
Predator should’ve brought a dog with him.
I'm surprised people didn't think it would work. Mud is a fantastic thermal insulator; it is used in jewellery and smithing to mask off parts of your work in tempering and annealing processes where a piece is often under direct flames.
Didn't the alien suit also had something to pick up the target's heart beat ? Seems to me the person would also have to slow their heart rate.
@@HepCatJackyeah,, it's just not thermals,, it has a few ways to see or scan
Cool. Many people don’t deal with mud in these conditions
@@HepCatJack It was added later in subsequent movies. The first Predator got really bare bones equipment in comparison
@jordytoke2908 I’m not. I’m fairly old and I’ve looked through modern thermals. If I ever have the money I’d love a thermal scope on my AR15. But I also know how thermals were way back when it was just prototype military gear. There’s a reason it looks so janky as an fx in Predator. It was sci fi level stuff back then. Now it’s refined enough to cost less than $10,000 that the rich kid can afford as a hunting scope. Bathing in mud is kind of genius but not something you might thing would really outwit actual retired veterans with actual nice FLIRs. Because it used to be a spec forces/CIA thing you gave the some elite high level shit back in the Cold War.
That's freaking awesome! I love that it works both under thermal, as well as regular vision. The Apache used to use mud to camouflage themselves as well as mask their scent from the animals they hunted. They used to legit sneak up on deer with mud on.
If they are so good then why did predator kill the Indian dude
@@raymondkidwell7135he forgot lol
@@raymondkidwell7135 Billy wasn't Apache. Even the name "Apache" demonstrates how "other" the N'de (Apache) were to their neighbors.
I love that there was this collab that I wouldn't have guessed to happen. Watching two different style channels come together for a mutual thing is awesome
This was a great video. The results low key blew me away.
it's actually nuts how no matter how much money goes into camouflage development and body armor; nothing beats state-of-the-art warfighting equipment better than good ol' dirt and water.
The difference is, camouflage has to work for hours, maybe days. Mud will dry out and warm up after some time and would be terrible for your health if you're already in a cold and very wet climate.
@@Lttlemoi just get more mud, is not that hard to get.
@@freedomloverusa3030Except that you’ll leave footprints in mud, which allows your adversaries to track you better. So you should probably avoid getting mud from the same place twice.
Evergreen branches works pretty dang good too.
And a doggo 🐶
I want to see part 2 to this, but in night time. This is so interesting to see.
Guys. True. Part 2 please at night. Make it a bounty. Let em use drones heatvision etc. find three of you using different methods of concealment in movies , the ice bath in minority report etc
Definitely and see how long the mud works til it stabilizes with the person's body temperature and render it worthless.
They couldn't find him in daylight without the help of a dog. At night their chances of seeing him would be even worse but the dog could still smell him just as easy as before. So I'd expect the same result.
@@megapro125 when the body heat and day time temperature almost equal its very hard to find him but the night time temperature decrease 10 celcius so they have more chance to identify the body because of the heat near objects are lower than him
You really can't beat the power of evaporation, which is what's going on here. You'd think he'd simply heat up the mud, but the water in the mud turning to water vapor cancels that all out.
EDIT: Also what's funny is, they already did this experiment... in the film Predator. I looked it up; they used a real IR camera for many of the shots. It wasn't just some special effect. lol
I don't think that's what makes the difference. I'm no expert but thermal cameras are highly affected by what's called "emissivity".
in simple terms, the higher the emissivity of an object, the easier it is to accurately measure its temperature with a thermal camera. mud has a lower emissivity than the human skin. low enough that we get the camouflage effect.
so it's not all about just raw temperature
@@MrKrawby and temperature changes the emissivity of a material, so what are u trying to say man. homeboy is right about the evaporation in this case, not to mention the uniformity of the mud covering whereas on human skin there is gradients in temperature at diff body parts making it stand out.
@@MrKrawbyyou feel cold after taking shower when you're wet. That's the simplest explanation of what OP is saying and he's right
@@MrKrawby In order for that to be true, mud would need to have a very low IR emissivity, like a polished metal. But if you look at an emissivity table, "soil saturated with water" has the same IR emissivity value as "skin" at 0.95. The reason that mud works so well is because it's simply cool to the touch - when it's wet - due to the evaporative effect.
Phase change is unbeatable in transporting the most amount of energy
This is mythbusters level content. Well done boys!
In fact - it makes me wonder - WHY didn't Adam and Jaime - or anyone on that crew, really - think to test this as one of the myths?
My bet is - someone did - but it was far enough down the list that they just couldn't get to it by the time the show wrapped up.
@@logandarklighter Or maybe, They already know that its not a myth? Mud is a really good thermal insulator that people already use to be protected from heat.
@@logandarklighter I remember they did, and if I remember right, they busted it because in their test, their body warmed the mud up. They couldn’t apply the mud fast enough before it became visible.
I don’t know what’s different from this test vs theirs, but that’s what I remember.
@@milkduds1001 Probably the type of mud and the conditions. Ambient temperature, humidity, day vs night, duration of the person covered in mud, clothing, water level of the mud, all of it could be a factor.
A lot better as they even cross-check their results.
That’s awesome, for years I thought there’s no way mud would’ve worked to mask heat like the movie. I now even more appreciation for Predator. A movie ahead of its time!
Corridor Crew+Donut Operator+Brandon=the collaboration I never I knew I wanted, but the one we deserved
I think what we’ve learned here today is that if you’re being hunted by the predator, you don’t want Arnie on your side. You want Harley.
Harley Quinn?
I would’ve brought a loud Bluetooth speaker and played predator clicking sound effects while searching for him. Just to make him feel a littlemore immersed.❤
This I think is the most impressive one to me. I thought the same as you guys, that you'd need WAY more mud, like just sloughing off of you amount of mud, and the fact that it only takes that much to completely fool a thermal camera is NUTS!
A thermal camera only sees the surface of any object, it doesn't penetrate much. That's why this works very well here.
Dude! Seeing Donut, Brandon and Eli show up in this video was EVERYTHING! Love it!
Crispy as well !!!
Love it
As usual, Brandon ruins every video he’s involved in
@@DctctxDebbie Downer
Thats why he has a large youtube following and is a frequent guest on other channels @Dctctx
I dont know if this is relevant, but in the movie, he was in cold water for a few minutes before being covered in mud, in a typical waterfall, water temperatures are very low and would have cooled down his body temperature for a bit, then the added mud, would have increased that body temperature drop. But you are right, it would not have covered his heat signature after the mud was starting to dry.
I like Jake’s stuff. Always unique and usually outdoors. Glad he’s enjoying himself in Texas and not just selling us stuff anymore lol
Wow… I had to do a double take when Harley from Epicmealtime showed up. After the insane punishment that guy put his body through, I cannot believe he is still alive.
@@DaMorg3oh shit I didn't recognize him!
What does Jake do to own a big property like that ?
@@heisenbergbad5375 He’s corridor’s producer
I think they made a very important point when scanning for him in separating what they know and what they see. They already know where Jake is because they set the shot up to get a clear result, but they ignore that to see how the Predator would parse the visuals. Too many would work backwards and find signs instead of using them. The IR scope seeing his eyes being an example. He knows that's a sign because he knows Jake is there, but he also looks at the whole scene to know it wouldn't be enough to key in on. It's similar to knowing Clark Kent is Suoerman. You're seeing the dots to connect because you already know.
Well, the eyes and mouth are a pretty strong pattern to recognize... and considering how thermals are the Predators primary mediod to observing humans, it would be something they could spot as a sign.
@@RipOffProductionsLLC Eyes and mouths are only good patterns when you know they're there. Otherwise, they just look like holes. Especially if there aren't enough defining features surrounding them to suggest a face.
@@bryanwoods3373predator is an alien though, with tech to cross the stars. We are centuries behind any thermal and target acquisition technology predator would have. Predator could also see in different / more frequencies than we do, and we wouldn’t be able to know because we can’t see it, and thus we probably would stick out like a sore thumb (though that wouldn’t make for an intense action movie so they nerfed the aliens).
@@It-b-Blair And yet the movie establishes that the tech can be beaten this way. It doesn't matter what a real advanced society can do, just what this fake one is shown using.
@@bryanwoods3373I think you are both correct to some extent, but eyes and mouths are instantly recognizable features; to the effect that people see faces in things where they clearly don't exist, such as the moon, Mars, or on toast.
That was awesome!!! Well done guys give us more cool stuff like that!
Awesome. Now test the opposite.
In Predators, the last surviving protagonist subverts the original movie by surrounding himself with a bunch of fires to overload the Predator's thermal vision instead.
I doubt it'll work anywhere near as well, but I'd still like to see it tested.
In Predator 2 they had thermal suits and the predator could see the black light beams… maybe test that :)
Royce also did the mud, as well.
It should depend on the delta (difference in temperatures) but it would be interesting to see how the ir sensor and software process the difference of hundreds of degrees in the surrounding air versus the ~100 degree body temp of a human lol
Maybe you can try the "urban camouflage" from sherlock holmes: a game of shadows (or maybe other films as well)
You basically have a costume with the pattern of the wall behind you and you try to hide in plane sight
they seriously haven't done that yet? Feels like it belongs right between Batman and Taken...
doesn't work but similar to the "grey man" doctrine which is where you dress in such a forgettable way that people need special training to notice you
MythBusters tried this and concluded it failed, but only because they tried this in a building, and even though it worked at first and the guy wasn't detected, the mud dried and it stopped working. I said to myself if they had tried it in wet mud outside in moderately cool temps, it would have worked just like in the movie. The jungles are known for being very cold at night and even sometimes during the day under heavy foliage. Arnold even had a bout of mild Hypothermia because they were not expecting the jungles to get so cold. They had all the actors covered head to toe in insulation wrap. Bill Duke fell severely ill and consequently was in bed rest for days, shivering even under a pile of blankets. Like peoples perception of deserts, it's not always hot and temps can swing wildly under various conditions.
Exactly this ! People underestimate how cold a jungle can get it's always wet there even if you are in the dead of summer you will still feel chill in the night
Jake testing movie tricks, is a series we all need
Wow you just made the movies so much more believable! I always had a base level of doubt that there'd be heat showing through the eyes or something, I dunno.
We did saw that heat showed through the eyes, in both the color version and the black and white version, but this was with them knowing where he was and filming him directly, if you didn't know where he was, and you saw that small bit of heat, you would never say that was a full grown human, perhaps a rat or some other small animal being there.
@@Argoon1981 Especially in the branches because in the end those plants have heat too so its easy to blend the excess heat showing among them.
@@RexZShadowyeah any type of noise will do. bc I don’t know if plants have any sort of heat that registers. Probably contours of heat-exposed vs shadowy parts.
That's amazing. And even that thermal imaging that the police helicopters and military use could barely make you out. I think if you'd closed your eyes there, or just had a bit more mud and squinted a bit, there would barely be anything to spot. Wicked stuff. Predator and Predator 2 are both timeless gems!
Harley showing up is the crossover I never knew I needed. Lemme find out Jake was epic meal time's camera man this whole time 😂
Would of been an awesome fact but he wasn't, Jake was originally and still kinda is a lawyer and does alot of the background paper work and legal stuff at corridor plus like producer stuff awesome skill set. Whether he lends his expertise to other UA-camrs I don't know buttttt I do know that corridor have known Harley for a long while and the people who live in Texas usually hang out often so Jake being in Texas as his main base I imagine he gets invited to some of the guntuber party's etc I've seen clips of him at bradons shooting days I'm pretty sure!
Way back in the Team Fortress Nerf video I was Heavy and he was Medic buffing me
Also, him knowing the Predator's race name. Dude is a huge nerd and I love it.
@@HarleyMorensteinweren't you also in some of the Node videos back in the day? And IIRC I thought Sam and Niko made an appearance on Epic Meal Time too right? Or was that Freddie?
Without watching the video, I can tell you that this works.
My information is based on an experience Hog hunting near Brackettville and Spofford, Texas.
I was hunting and tracking a hog on foot and my rifle at hand was a bolt action .257 Roberts. On the rifle was a thermal scope.
I’ve used the scope numerous times, both day and night modes.
Needless to say, I felt confident using the scope.
The event occurred at night, for those who may want to know that detail.
I stopped using the light for a while because I didn’t want to push the hog further than I wanted it. When I looked into the scope I could not see the pig. I knew what it looked like and the fact it was covered in mud was what let me know he came from the pond not far from the HQ.
So I looked into the scope and could not see the heat signature of the hog. I did finally find it, but only because he was moving, and all I barely saw was his silhouette. I was not able to get the kill, as by the time I saw the pig, he was already in the thick of the brush.
There was no trace of body heat whatsoever.
The pig was obviously smart, but not for the “4th-wall” reason that would be a good joke, but because it was the heat of the summer and the mud was used to cool the pig down. It just happened to have worked for the thermal scope that was being used at the time.
I think it's also worth noting that in the movie, Arnold doesn't *have* to know it relies on heat vision for it to be an effective tactic...because mud masks multiple factors, temperature, color, smell...
Also in the movie, Arnold is careful to be as still as possible when the predator is looking his direction and when he does move, it's from one hiding spot to another...again decreasing his visibility.
Jake testing movie logic is my new favorite series
One day Jake is gonna walk into the office disguised as Clark kent, get someone’s attention, disappear like Batman, then everyone looks for him with thermal cameras but can’t find him because he’s covered himself in mud. When they finally find him they chase him outside to the street, where he disappears like Jason Bourne.
My theory of why it works is because the mud is wet. When the wind blows across the mud it evaporates the water in the mud keeping the outside layer of the mud cool enough to be around the same temperature of the ambient air. If the mud were to dry completely I think you would be able to see him with the thermals.
I had the same reasoning as Brandon. I thought the body heat would eventually heat up the mud too much to be effective. Been wondering about this for a while. Great idea to test it.
Well, it will eventually do either that or cool the body down too much to be safe for the person, it is actually a thing that has been discovered in Ukraine since they are using thermal camouflage too
That would happen once the mud was completely dry.
That was amazing. I thought thick mud would work but that was movie-level testing and it worked so well!
I love that they had fun with this, too lol. Definitely, a success. The only asterisk is that he had to apply a thicker coat of mud than what Arnold's character used but not that much more really. Other than that, the mud probably has to be fairly wet and not be on too long to get too dry.
Jake's videos are always so good. Really captures the feel of the old school corridor crew videos that I fell in love with.
Points for the dog.
It was entertaining. Thank you for the video. Predator is one of my all time favorites.
"And I would've gotten away with it, if it weren't for that stupid Mutt"
I love it when Jake is involved in the videos! The diversity of personalities at CC is off the charts. Cool concept!

Getting Eli (military), Crispy (military), Donut (cop), and Brandon (congressman) all in a corridor video is blowing my tiny mind.
I'm loving these collaborations.
Donut, Brandon and some other fellas
I thought it would work but with a time limit until the mud heated up. That worked way better than I thought it would.
Maybe it is a time limit, but it would be hours
We see at the end when they find him that his body was significantly hotter than the branches around him. But that's because he'd been sitting in one spot without new mud application for long enough.
Admittedly, I think part of why the thermal cameras couldn't catch him is because of how much foliage he was under. The Thermal Cameras just don't have the same level of resolution and focus as a human eye.
“MythBusters”
Tory: Coming up on “MythBusters“, will mud beat the thermal motion sensor?

Loving Jake's experiments! This one was definitely a surprise.
They should have done this at night, when his body heat would be much higher than the surrounding terrain.
Those infrared scopes work because they pick up differences in heat, and during the day the ground is radiating a lot more heat.
I really don't know if it would have been clearer, but I think it would have been more accurate in trying to recreate that scene.
Brandon has reached a new high point by making it in a corridor video
Now time to be the first content creator to hold a federal office.
and he's now 2 degrees of separation from Adam Savage as i think the camera guy was with Nico and Wren in SF for the noseslitting FX...
Veritasium uploaded a 25 minute video on termal/night vision yesterday which was heavily informative and entertaining, and now day later this drops. Great timing, both videos are excellent!

Even Corridor is not immune from being Dereked. I suspect Varitasium is a time traveler.
You probably can't test this one, but I always wondered if you really could get an 1885 locomotive up to 88 miles per hour as in Back to the Future Part III.
As I remember from playing with one of the cheapest thermal cameras ($200 SeekThermal or something), it was only good at detecting living creatures on a cloudy days - on a sunny day, even if it's actually quite cold outside, the sun would heat a lot of surfaces and I wouldn't detect a dog on the road or a pigeon in front of a tree, because both the road and the tree would be quite warm. I didn't try it in tropical jungle, though, and nobody was covered in mud.
Exactly, if you have tropical temperatures close to a human body, you are hard to detect even without mud.
These are the type of guys that you should be collaborating with. Do more in this direction.
What'd be really cool to see would be to cover jake up in fresh mud, sit him in a chair, and record him with a thermal camera to see how long it takes the mud to stop being an effective heat sink.
My guess is that there are two mechanisms at play.
The first is the clay content of the mud: clay requires a fairly large amount of energy to shift its temperature (which is why it is used for thermal insulation, like coffee mugs). it will eventually heat up enough to radiate in the same spectrum/intensity as a human body, but it's not going to be instantaneous.
The second is going to be active cooling from the water content of the mud. Water is also a great thermal sink, and it also evaporates very easily and carries that heat energy away.
I think that, given enough time, environmental heat, or airflow, the water will evaporate, leaving just the clay content of the mud behind, which will then begin to heat up and become visible to the thermal camera.
i mean this is what happens in the movie as he moving around and causing his body heat to rise higher than normal as well
Wow I literally never would've expected to see Herrera, Donut, Crispy and Harley on this channel. The most unexpected crossover of the year.
Yeah! I think they wanted to give the gheys of the gun community, the opportunity to do something useful for once.
I think they didn't want to alienate some of the audience: make them stay because they are hooked with the idea of the test, even if they hate Brandon and he happens to be on the video. I myself love Brandon, mostly because of his personality: not a huge fan of his political compass, but we can agree to disagree.
This was so cool! If I had to guess I think it's the evaporative cooling of the water in the mud that massively helps.
Yes. It's basically turning heat radiation, which the thermals are calibrated to pick up on, into heat convection. The body heat instead of shooting out straight into camera lens at the frequency the camera is designed to pick up, instead gets trapped in the water molecules and lifted up into the air. Thermal cameras of this type are deliberately designed to cut out the portion of the spectrum where heat convection would be visible, because otherwise just your breath would pollute and wash out the picture. And that's why it works so well - it's using the camera's design against itself.
If they had an industrial camera designed to pick up on convection, he would stand out like a steaming sore thumb.
I always kept on reminding this particular scene and wondered why the Predator could not see his EYES,....one of the most glowing items in a human body, but not covered with mud and directly looking at the Predator.
why could be ? 🤔
maybe they also covered around eyelid ?
It's because the eyes and nose are colder than the rest of the body.
I cannot believe how well this worked
Due to recent world events and from a tactical standpoint, thank you guys for this very educational information.
Of course it works - but only for a very limited amount of time. You become visible once the body heat has dried and warmed up the mud.
For this to work continuously you have to keep the mud wet.
Prediction: Mud warms up. Gets visible
Spolier Alert: Oh my god. This is like the mythbusters episode where they tested if elephants are afraid of mice and everybody was flabbergasted. Good job boys, what a video!!!
your "prediction" was voiced many times by the dudes in the video
Indeed it was, I was grinning a stupid grin everytime somebody said it @@ColinFox
Prediction: water is wet
Prediction wrong.
Great seeing the Texas crew- Brandon and Donut on your vids :)
I was getting annoyed when they kept saying "the mud will heat up". I'm not even an outdoors person and I know as long as the mud is wet any heat your body gives off. Will be evaporate so the only thing that happens is the mud gets dryer and your body gets colder.
Great Video! Quick suggestion: You should have or could have also make a without mud hide and seek to see how GOOD thermal camera are, then show off how easy it is to beat them or explain why is happens on a more sciency approach.
They do show a guy standing around without any mud and how much they stand out from the environment earlier...
So many little nice features in this video :)
I was also not expecting these results. I would like to see this revisited at some point. What kind of mud is the best? What happens if you try to run covered in mud? Can you use mud to conceal other things like a car? Maybe a internal combustion makes too much heat to mask but a small electrical vehicle could be concealed fairly well? What about ground based drones or electrical observation equipment?
This makes me so unbelievably happy! Well done! And shout out to my Texas “experts”!
UA-cam always get better and better. It is very great when your favourite channels colaborate.
Hearing Brandon say "Today it's going to be for hunting you" is sublime
This could be a segment on it's own so entertaining to watch.
"If it uploads, we can subscribe to it . . ."
Just those few seconds of the Predator reminded me why it's a fricking masterpiece that needs NO SEQUEL, NOR PREQUEL, goddammit.
