I miss Mythbusters so much.
It’s amazing to me that Discovery hasn’t tried to bring Mythbusters back. Instead they double down on Ancient Aliens and Pawnstars garbage.
If you need you fix Adam savage is very active on YouTube and is just a wonder human being. It’s not MythBusters but Adam was a light during Covid and someone I put on regularly on YouTube.
Yeah, I watch him. It’s not Mythbusters, but it’s still entertaining usually, even when he’s doing the most boring things. It really shows how good he was as an entertainer.
My favorite thing about Adam’s videos is the way they are edited, they leave in some silence so you can see Adam’s head gears working as he’s solving a problem. It sorta feels like we’re solving the problem with him.
Quoth Adam Savage: “It’s not ‘my experiment failed’, it’s ‘my experiment yielded data!’”
Being able to separate your ego and desire to be right from the learning process is such an important skill.
Or at least use classical conditioning to associate the I’m wrong feeling with the impending new cool facts feeling.
Plus being able to figure out a semilegitimate excuse to blow stuff up. “This could be very dangerous so we’re going to do several things to make it safer. That’s teaching safe lab techniques, so it’s educational!”
For anyone missing the show, there was a wonderful project called Streamlined Mythbusters where fans edited each episode down to remove the filler, pre and post ad recaps, etc. They usually also would reorder things so each individual myth was seld contained.
It’s wonderful, but some episodes legitimately got cut down to be 16 minutes long with no real content loss, which can be kind of jarring.
There is also Smyths, which is the same thing.
Unfortunately Mythbusters edits have a tendency to get pulled from the typical video sharing sites rather quickly. I wish someone would make a torrent of the entire series edited this way, and call it a day.
What, like the pinned post on the smyths reddit page?
Excellent; thanks. I cached the torrent to Real-Debrid, so if anyone reading this so happens to be using that service, you can download the torrent directly at 1Gbps by pasting the magnet link (the first one) in Torrents section of the website.
Oh god, I forgot, it was during the “REALITY TV!” boom where marketing and hype had more substance than the shows themselves, and if the show had substance… edit it like it is Reality TV…
I do not miss that.
You can find a torrent of all of them. I love putting Plex on shuffle when I’m doing chores around the house.
This is why most skepticism based programs don’t work, and Mythbusters did.
They didn’t try to be smug about it, they didn’t belittle people who believed in the myths, they never brought religion and politics into it, and the biggest pitfall they avoided: They never pretended that the “science was settled” and that they “already knew everything”, they simply did the research and went where the data took them.
Too many skepticism based programs seem to think the scientific method is running into a church, yelling “FAKE!”, and then running outside to hurl insults at passersby.
Mythbusters didn’t do that, they skipped the dogma and went straight to the science.
Also, most of the myths weren’t “serious”- it wasn’t like they were debunking flat earth or something.
I hate that debunking flat earth is now seen as serious rather than a 5th grade science experiment.
I actually got fired because I told a Flat Earther to leave the store I worked in, it was closing time and he was harassing people… But if you bitch enough to corporate you can get us to walk on water…
Whatever, I’m a Janitor now, never doing retail again.
It’s too easy to debunk flat earth, if it were flat cats would have knocked everything off by now.
True enough.
I mostly watch that one guy on YT for his dog…
It doesn’t matter how you run because ALLIGATORS WON’T CHASE YOU.
I used to live in Florida on the edge of a big lake where my landlord had carved out a lagoon that mama gators used to hatch their broods, so there would often be between 50 and 100 little alligators chilling out in my backyard sunning themselves. For fun I would try to sneak up on one of them and poke it on the head just to watch it and all the others scatter into the lagoon. Everybody I told about this thought I was absolutely batshit crazy, but I knew that at the time there had been something like 5 alligator attacks on humans in Florida since the 1940s, always on little children playing in water (I was obviously a little child mentally but physically I was a 200-pound adult man). So I knew I wasn’t risking life or limb doing this. For the record, my sneaking up technique was to stand stock still and only move a step or two towards the gator whenever the wind blew; it seems that the gators just took me for a swaying branch and ignored me.
What made me stop doing this was one day I happened to look down at what I thought was a big log and realized that it was actually the mama gator, about 12’ long from tip to tail and probably 2’ in diameter at her midsection. I was fairly confident that she wouldn’t attack me on land either - but not that confident.
So, we meet at last, Florida Man!
No way! I left and I still have all my teeth.
but not that confident.
That’s how you bust myths!
Sometimes they called stuff busted because they couldn’t personally do it though, even though the myth involved elite athletics. I was pretty stoked when they brought in an actual ninja to test if ninjas can grab arrows out of the air. The guy actually did catch some arrows, which was quite amazing.
Yeah… There are many pitfalls to doing a Skepticism based program, sadly one of the few Mythbusters DIDN’T avoid was “Well I can’t personally do it, so it’s impossible for everyone!”
“Could the DOOM marine actually carry all those weapons while running around?” - Adam and Jamie couldn’t manage it, but they brought in someone who could.
Ha! That was fun.
I thought you were joking till I clicked the link.
Which was ridiculous considering they’re a couple of science nerds with no physical aptitude at all. LOL. They nailed the science stuff though.
I liked the one where they tested it you could stop a sword by slapping your palms together to stop the swing like in ninja movies They actually built a machine with rubber hands to simulate it. Long and short of it … No you can’t
But maybe… JK. The strength required to do that would be inhuman.
Yeah, one that I always think of is the see-saw one where a sky diver’s parachute failed so he aimed for a see-saw with a girl sitting on one end which resulted in the girl launched shot upwards and then landing safely on top of a building.
Their first test used basically a metal plank on a fulcrum and the forces did more to bend the plank than they did to launch the girl and she didn’t get high enough.
Their second attempt used a see-saw that was built using suspension bridge tech to essentially make it instructable, resulting in fatal forces from the launch. At this point, they called it busted.
But I see two unrealistic extremes where reality would exist somewhere in the middle where see-saws are designed to not break easily but not to the point of being indestructible and there might be a sweet spot where the forces are high enough to launch girl several stories up but not high enough that she dies from the forces.
Also, for the bull in a china shop one, I’m guessing that saying resulted from a bull ending up inside a china shop during a running of the bulls event, where stress would be high and there wouldn’t be an easy and obvious path out on the other side, plus maybe a shopkeeper suddenly trying to get it out in a panic. I think that would get the expected result, especially after a few shelves have broken and each step makes more broken sounds.
Ive told people this many times, we need to create more room for failure. From school, to jobs, to building businesses, to loans, to health.
If we can try something because if we fail we can try something else, we would find a hell of a lot more to care about in this world.
And the most important thing we would care more about is ourselves
Mandatory Dwarf Fortress in every school.
Okay thats it im tired of people commenting about this Dwarf fortress. How much of my soul does it cost? Whats that in hours needed?
First, read Boatmurdered. Then realise it’s worth whatever the cost is
“Failure is always an option.”
My favorite is planes on a treadmill.
Mostly because fans still argue about it and it’s hit the point they had to ban PoaT comments.
Which is insane as it’s not that difficult to understand. When a plane is on the ground, its gear/wheels will roll at ground speed, but the wings provide lift at airspeed.
If the ground is being moved under the plane (as on a treadmill,) the wheels will just roll faster.
Sure they’re not zero friction and some of that needs to be overcome; but this is something encountered on a daily basis all across the world- or rather, the opposite.
If the wind is coming from ahead, its airspeed is increased and the plane needs a lower ground speed to get into the air where if the wind is coming from behind, then they need more.
(This is why carriers set course into the wind when launching jets,)
At no point is ground speed and airspeed necessarily the same (i suppose you could have a calm day, but most days, the wind is blowing at least some.)
Plane on a treadmill is really interesting because if you understand how planes work its so obvious what will happen you don’t need to test it. Planes move on the ground by running their engines, which push against the air, the wheels provide zero motive force. It’s also why planes need tugs to move away from the gate, you can’t run the engines in reverse. Planes are not cars, but people tend to assume the thing they don’t understand works like the thing they do understand, and refuse to believe their hasty assumption is wrong even when told directly their hasty assumption is wrong.
You actually can run the engines in reverse. They have thrust reversers. There’s very good reasons that they do not reverse the plane from the stand using the engines, but it is possible.
my criticism of PoaT actually has to do with the scale model they used to prove it.
scale aircraft have ridiculous power-to-weight ratios
but that’s just me being a stickler.
I think the confusion is that the conveyor belt is running at a fixed speed, which is the aircraft’s takeoff speed. That just dictates how fast the wheels spin, but since the plane generates thrust with its propeller, the wheels just end up having to spin at double takeoff speed. Since they’re relatively frictionless, that’s easy.
The more confusing myth is the one where the speed of the conveyor belt is variable, and it always moves at the same speed as the wheels. So, at the beginning the conveyor belt isn’t moving, but as soon as the plane starts to move, and its wheels start to spin, the conveyor belt movies in the opposite direction. In that case, the plane can’t take off. That’s basically like attaching an anchor to the plane’s frame, so no matter how fast the propeller spins, the airplane can’t move.
Except it’s not like attaching an anchor. The plane isn’t physically attached.
The wheels will just roll double whatever the current ground speed is. If the plane has enough thrust to take off with the treadmill moving an inverse of its take off speed, then it has enough force to start rolling, too.
At most, the force applied by the treadmill would be sufficient over enough time to lengthen the take off roll, but given enough space to do so, the plane will take off.
To keep the plane from rolling forward; the treadmill would have to be able to apply an equal force as the engines, it can’t do that through the wheels- the wheels can only apply a force equal to their rolling resistance and friction in its mechanics.
If the conveyor moves at the same speed as the wheels, it is exactly like attaching an anchor. That isn’t the myth they were testing, but it’s a more interesting myth.
it can’t do that through the wheels- the wheels can only apply a force equal to their rolling resistance and friction in its mechanics.
It can do that if it can spin the wheels fast enough. Picture the ultra-light airplane from the episode with big, bouncy wheels and a relatively weak propeller. If the treadmill was moving 1000 km/h backwards, that little propeller could never match the force due to rolling resistance from the wheels.
Just to clarify; you understand that because the engines are pushing on the plane itself and not the wheels, by the time the wheels start moving, the plane is already moving relative to ground and air alike.
Which, said another way, this thought problem appears confusing because it’s being considered from otherwise irrelevant reference frames.
An anchor sufficient to keep the plane from rolling forward is different because the force it is apply is significantly greater.
Sure, you can deflate the tires and increase the rate of spin on the wheels. But at that point, you might as well ask “can we creat a scenario where planes can’t take off”
To which the answer is definitely “Yes”,
And as a side note, if we assume the wheels are indestructible, which I’d argue is only fair, then even if what you’re saying is true and we ramp up the drag induced by the wheels sufficient to counter the engines… then the wind generated by the rolling treadmill would be producing a sufficient headwind for the plane to take off. (Remember, the air resistance of the treadmill’s belt moving will accelerate the air some.)
But again, the wheels have almost zero drag to begin with, the speed at which the roll is independent of both the actual groundspeed and the airspeed of the airplane.
If it has the thrust to over come friction at take off speeds, and at standing, then it has enough power to get to take off velocity eventually.
On the other hand, this entire conversation assumes the thrust to weight ratio is less than 1. If it’s more than one, well they just…. Go straight up.
Just to clarify; you understand that because the engines are pushing on the plane itself and not the wheels, by the time the wheels start moving, the plane is already moving relative to ground and air alike.
The wheels are attached to the plane so they move at the same time as the plane. But, I get what you’re trying to say, that the wheels are effectively being dragged by the plane, they’re not powering the movement. But, what you need to think about is that if you oppose that dragging by moving the conveyor belt in the opposite direction you can prevent the plane from moving at all. Yes, the wheels are merely dragging and there isn’t a lot of friction there, but friction increases with speed. And, if you move the conveyor belt fast enough, you can stop the plane from moving relative to the ground, which can stop it from moving relative to the air, which can prevent it from taking off.
An anchor sufficient to keep the plane from rolling forward is different because the force it is apply is significantly greater.
No, by definition it’s the same. The conveyor moves with however much speed is necessary to stop the forward motion of the plane. The conveyor would eventually go so fast that it generated enough force to stop the plane from moving, so it’s indistinguishable from an anchor.
Sure, you can deflate the tires and increase the rate of spin on the wheels.
You don’t need to deflate the tires, you merely need to increase the speed at which the conveyor moves to match the speed of the wheels.
if we assume the wheels are indestructible, which I’d argue is only fair, then even if what you’re saying is true and we ramp up the drag induced by the wheels sufficient to counter the engines… then the wind generated by the rolling treadmill would be producing a sufficient headwind for the plane to take off
That seems like an unfair assumption because you’re assuming that the conveyor belt has second-order effects on the air (i.e. generating a “wind” over the wings of the plane), while ignoring the second-order effects the conveyor would have on the wheels (massive heat from friction leading to failure).
On the other hand, this entire conversation assumes the thrust to weight ratio is less than 1. If it’s more than one, well they just…. Go straight up.
I mean, the discussion is of a plane, not a helicopter or a rocket. Even jet fighters with a thrust-to-weight ratio of more than 1 typically have engines that only have that ratio once they’re at high speed, not from a standing start. That’s why even fighter jets on carriers need a catapult-assisted takeoff. A VTOL aircraft like a Harrier wouldn’t need that, but then its takeoff speed is zero, and the myth isn’t very interesting when the conveyor belt doesn’t move.
The wheels are attached to the plane so they move at the same time as the plane. But, I get what you’re trying to say, that the wheels are effectively being dragged by the plane, they’re not powering the movement.
no. I’m saying that by the time the wheel is rolling, the plane’s is already moving forward, the engines have already overcome the drag in the wheels. the treadmill is locked to the wheels, not the plane. The plane would continue accelerating even as the wheels reported weird rates of turning.
As for the (very brief) time delay, that’s a function of the plane’s gear’s suspension that is quite well sprung.
the rate of roll on the tire is, effectively, decoupled from the airspeed (and groundspeed) of the plane. which makes this:
No, by definition it’s the same. The conveyor moves with however much speed is necessary to stop the forward motion of the plane.
… entirely different. an affixed anchor does not allow the free motion that a wheel would.
You don’t need to deflate the tires, you merely need to increase the speed at which the conveyor moves to match the speed of the wheels.
And one of a few things happen. Either the plane has enough engine thrust to overcome the acceleration induced by the wheels, and therefore takes off, or it does not.
In the case that it does not, the wheels would continue spinning in increasing RPM until the plane begins moving backwards. because, again, the airspeed of the airplane is not dependent on the wheel’s RPM. Assuming the airplane doesn’t crash from suddenly becoming incredibly difficult to control… eventually it would take off anyhow. because the airflow over the wings would still generate lift. (though they would become horribly inefficient.) and therefore take off.
this is of course ignoring the whole “can a pilot actually control that and manage a take off like that” thing. If you don’t want to grant godlike piloting skills, we could then just make the treadmill irrelevant and leave the brakes on.
I’m saying that by the time the wheel is rolling, the plane’s is already moving forward
The wheels are attached to the plane, so they move at the same time. There’s going to be slight flex due to rubber and metal not being insanely stiff, but essentially as soon as the plane starts moving forward through the air, the wheels start rolling forward along the ground. Since the conveyor belt cancels the forward movement of the wheels, the movement of the plane ceases too.
The plane would continue accelerating even as the wheels reported weird rates of turning.
Initially, for a few tenths of a second, or a few seconds sure. But, during that time, the conveyor belt would be moving faster and faster as it matched the speed of the wheels. The faster the conveyor moved, the more friction there would be, and the more drag there would be from that friction. Eventually you’d reach an equilibrium where the drag from the wheels was equal to the thrust from the engine, and the plane would cease moving forward. It would be exactly like the plane being anchored to the ground, except instead of a stationary anchor, the anchor would be a spinning treadmill in contact with a spinning wheel. In a world without a magic conveyor belt that could instantly adjust to the speed of the wheels, there would be some slight forward and backward movement of the plane, but that’s just like being attached to an anchor with a bungee rather than a rigid rope.
an affixed anchor does not allow the free motion that a wheel would.
The wheel doesn’t have free motion. By definition, the conveyor is moving at the same speed as the wheel, so the wheel is locked in place. With a real conveyor belt there would of course be some lag as the motors of the conveyor accelerated the belt, but using the hypothetical as defined, the axle of the wheel couldn’t ever move because every rotation of the wheel would be matched by a movement of the conveyor belt.
And one of a few things happen. Either the plane has enough engine thrust to overcome the acceleration induced by the wheels, and therefore takes off, or it does not.
The thrust would have to be infinite because, by definition, the conveyor is always going to match the velocity of the wheels. If the wheels were truly frictionless, then the conveyor belt would have no effect at all. But, any real wheel will have some friction that will increase with speed, so there will always be some speed where the force backwards from the friction of the spinning wheels matches the force of the engine.
As an aside, my guess is that most real airplane wheels would probably fail pretty quickly at just double the normal takeoff / landing speed. The centripetal force acting on the spinning parts of the wheel and tire increase with the square of the velocity, so 2x as fast means 4x as much force. 3x as fast and 9x as much force. So, if you did this with a real wheel, you’d destroy the wheel pretty quickly. Of course, the same applies to the conveyor belt, but I’m going to assume that it’s specially engineered to survive this challenge.
the wheels would continue spinning in increasing RPM until the plane begins moving backwards
The plane wouldn’t move backwards because if the wheels slowed down, the conveyor belt would slow down too. Of course, that’s in a world where the conveyor belt could adjust its velocity instantaneously, but for this thought-experiment you can say that if the pilot cuts the engine or something, the wheels don’t spin as fast, so the conveyor belt slows down, and the plane remains in one spot.
eventually it would take off anyhow. because the airflow over the wings would still generate lift
In the thought-experiment world, there wouldn’t be any airflow over the wings because the plane would be stationary. In reality, there would be some airflow due to the movement of the conveyor belt, but the wheels would probably melt long before that was enough air to give the plane lift while stationary relative to the world around.
Plane on a treadmill always seems so obvious to me. Planes don’t have power connected to their wheels. Put a plane on a dynamometer and crank the engine up as fast as it will go, and the wheels will still not spin. At the same time, water planes use pontoons and are still able to take off just fine.
The question I have is, can a plane take off with a tailwind that matches the speed that the propeller is pushing out.
My favorite is the fan mounted to the boat blowing the sail causing the boat to move. I mean there are a shitload more experiments in fun episodes that are far better and more entertaining, but this one is my favorite because it flies in the face of logic. It shouldn’t work. My brain rejects the possibility. But physics and fluid flow work otherwise and I found it pointlessly infuriating only because I’d been unassailable in my confidence that it couldn’t possibly work. Yet there it is with a perfectly logical explanation. I still find it irritating even if I accept the reality of it. (Episode 165 if anyone’s wondering)
That said, I still follow Adam on various platforms. That enthusiasm and joy of discovery is all still there, along with some maturity and some life observations. Literally the only celebrity figure I follow.
Sometimes there’s a twitch stream of random mythbusters episodes. It’s so fun.
I wish they came back :/
We need less entertainment that runs forever and more that has a plan for how long it should be.
In this case it ran as long as it was feasible, then a little longer and then they where done.
I think Mythbusters is a little bit of a different case than something more narrative. There are always new myths to bust; every generation needs something that makes science cool. I guess now that’s a role mainly filled by various YouTubers.
I still wanted them to see how much dynamite it would take to remove a dead whale.
I wish more people in general would be OK with being wrong. Noone ever learned something new without knowing they’d been wrong
