"I'm gonna try not to make a gun in this video"
Proceeds to make what looks suspiciously like a gun.
Some people are confused about things in the video that i didn't explain very well.
1. Me throwing the coin had nothing to do with anything. I just wanted to know how fast I could throw a coin and also if it was possible to keep it on the skinny edge.
2. I wasn't suggesting that you need to throw the coin off the empire state building to reach a fast enough speed to kill someone. Just that by dropping it with a spinning motion would keep it on the skinny edge allowing it to reach a much faster terminal velocity.
3. The terminal velocity I calculated was actually slower than ones that people in the comments have estimated using physics programs. Some of the estimates were around 300 kmph.
The point of the pig test was to show what a coin traveling at 230kmph (slower than the terminal velocity) would do to you. Turn you into a piggy bank
4. Also the point of the dam test was to show that the spin would at least keep the coin on the skinny edge for 45 meters.
5. How you going?

The one thing he still needs to test are side winds. I suspect that during the fall from the Empire State, that side gusts would hit the coin and send it off-face. The counter to this is a really strong spin, but I don't think you can pull that off with enough inertia - mostly because the coin doesn't have enough relative mass. So, I still think there is a real possibility that a spun, heavy coin would not kill someone if you dropped it.
Also worth noting that the original myth is a penny, which I think even with these ideal conditions wouldn't kill anyone.
Superb video as always.
6:30 I like the little detail that he went from safety glasses to a full face shield out of fear xD
The reason why you were seemingly throwing coins at 172km/h is because of perspective. The cameras FOV is a cone starting from the camera, meaning the farther from the camera something is the more distance it can travel before it goes out of frame. This means that when looking at the coin passing in front of the markings, it can go from covering one marking to covering the next marking going less distance than there is between the two markings. This can be counteracted by moving the camera further away and cropping in, decreasing the slope of the cone relative to the surface vector of the marking board, as the cone shape is now closer to a cylinder than before.
Can you Explain this in Easy language
@@fara-sarait do the slope so perspective look weird
E
You are kind of on the right track but not quite. First of all: don’t think cone, think pyramid. Second: What you are describing is called parallax. The parallax effect is definitely a factor but I think you are overestimating it. One additional issue here is that even with so many fps, in an individual frame the coin is very blurry. This makes it hard to make out its exact position. I expect this to contribute a lot to the error. That combined with the parallax effect might significantly affect the result. There is also lens distortion. However, that is mostly a concern when pure pixel distances are used. In this instance the painted bars werde used which of course are equally affected by lens distortion therefore eliminating it as a factor in theory.
Another adding factor to the error is the distance between the coin and the scale: the higher it is, the bigger the error

The reason it took the drone so long to descend is because the downward facing sensors were blocked by the coin contraption, so the drone kept thinking there was something below it, and was descending at "landing speed"
And it should be possible to disable that sensor somewhere in the settings (at least possible in my mavic pro, mini has a different app now)
Just don't forget to enable it again later, or you risk slamming your drone into the ground at its max descend speed

Now that's how to do a sponsorship! Not overly youtubey, and shows off the highlights of a quality product and why it may matter to the people watching the video. I'm definitely going to buy from flexispot when I next move and need a desk.
Wind exists. I've been on the Empire State Building and it was windy af up there. A coin wouldn't be able to stay vertical with that wind.
They also used a coin 10x heavier than a penny. I don't know what's the weight of a quarter but I know it's not the 10x the weight of a penny.
The fact you had more confidence in the desk shielding you instead of your car is insanely hilarious.
Tbf the top of your car is usually some pretty thin sheet metal, some cork and fabric
Most cars are not designed to stop projectiles. They are designed to give way to absorb heavy impacts.
@woalk This cars are built to slow down impact from other cars by allowing itself to crumble better absorbing the impact essentially making up intentional weak spots.
But unless modified its not made to protect against high speed projectials

@@kernelpanic2887well they are designed to be made of wood and tough as fuck if they are of good quality.
I like the idea of a post apocalyptic character that uses a "Coin Rifle" as his primary weapon. Going from place to place looking for "Ammo"
Probably becoming less realistic now as physical currency is becoming less popular. Also, "rifle" is probably an inaccurate name for a coin gun as "rifle" refers to a barrel with helical pattern of grooves; any feasible method of shooting a coin that i can imagine would not involve such a barrel. You may be able to form a crude bullet/slug by hammering a stack of coins together and fire them from a shotgun. I guess some type of coil gun or rail gun could be made to fire coins, the exact composition and shape of the coins would probably be important.
"only my railgun" intensifies.

@@EEEEEEEE thank you for your input, E
So I calculated an estimate using wolfram alpha.
Fall distance: 377m (1237 ft)
Drag coefficient: 0.431711746 (best one I found)
Projected surface area: 87.52 mm^2 (spinning dodecagon with thickness)
Fluid density (air): 1225 g/m^3
Weight: 15.55 g (like half a bullet)
The result was 67 m/s (241 km/h, 150 mi/h) for the speed of the empire state building (visiting area) and
82 m/s (295 km/h, 183mi/h) for the terminal velocity
which are very dangerous indeed (deep tissue injury, bone fractuce)
You would also keep the coin stably spinning for at least 11 seconds.
Thats awesome. I shot the pig head at around 230 kmph so 240kmph could definitely be deadly!!! I need to use programs like this
It would be a challenge to keep it spinning around z axis only for 11 seconds considering wind. It would need to have a hole and be much bigger to have the same mass 🤔
I agree washers would probably spin more stably because more of the mass is further from the center, but I also think the hole would increase drag substantially. You could probably get the best results by using a washer but taping over the holes
The entire point was a penny though, where has 15.55g come from exactly?

The problem with accelerating an object to terminal velocity with anything other than gravity is that it accelerates far too quickly, the forces acting on the coin have much longer to make it unstable in flight when falling and makes it more and more likely to start fluttering... slowing it to be relatively harmless. You'd be better to use a shape that is relatively stable like a ball bearing if you really were a homocidal tourist.
I appreciate the suggestion for alternative murder weapons you included at the end
I could calculate actual terminal velocity, but I'm too lazy.
@@Ociloc Im here to please

The reason you may have had trouble getting the done down: Mavic Minis have sensors on the bottom. The magazine almost certainly wouldve triggered the sensors, causing the drone to think it was perpetually right above the ground. As they're programmed to fly up to about 1m above the ground it just kept flying up (as seen in the video) until it hit the legal altitude limit and ran out of charge, falling slowly back down to the "ground" which it thought it was directly above.
Yh I just comented that…

@@user-yl7mr3ck5l This doesn't debunk it at all though. The myth that was busted was dropping a penny off the empire state building. This video appears to not be about either pennies or dropping things so is completely irrelevant to the myth, though very entertaining.
@@nephatrine Actually, I think you'll find that the majority, if not all, of Mythbuster's experiments are severely lacking and don't account for a myriad of variables. It's still a decent show, and relatively informative, but it's hardly the be all, end all of scientific mythbusting. It was all very surface level, they had limited time to do things and a limited budget. The main thing was to make an entertaining show. I wouldn't take most, if any of it, as irrefutable scientifically proven fact however. (In fact, I wouldn't do that with many actually scientifically proven facts, in the first place. There's very little which turns out to be actually irrefutable. We learn, we grow, we learn more.)
Also, this video is entirely about dropping pennies. And as stupid yet entertaining as IDAT always is. Though hardly a "debunk" video, lol.
@@anomonyousmythbusters frequently take liberties to make it more plausible.
@@nephatrine Well one huge problem with the penny drop from the empire state building is if dropped from anyplace the general public has access to from any height there or above it will always land on a ledge. The lowest ledge is not very high up meaning it will basically always catch a thrown or dropped penny or other coin. You could throw it way out sure but even then you wont manage to hit any given target.
As far as the myth busters go a insane amount of their stuff was debunked and shown to be false. Effectively once the internet was in basically every home the show lost popularity and ratings flat lined as people would see something on the show then go and look up the physics facts or other facts related and just stopped tuning in

You could make a handheld rod with a slot for the coin to go in. When you swing the rod, the centrifugal force will make the coin roll up the rod and get launched out the end. This will make it go fast while also making it spin. It is sort of like a lacrosse stick.

@@Ididathingozzie spider magick?
It should be possible (but a long way from easy/approachable) to calculate how fast the coin needs to spin to stay on its edge the whole way down, within a reasonable tolerance.
What would really happen is that little variations in air velocity would apply forces attempting to unsettle the coin. What the spin stabilization _actually_ does is change the _direction_ of those forces to 90° off of the oncoming air direction. This will create gyroscopic precession that'll make it tend to fall in a spiraling pattern.
The gyroscopic effect will also resist unsettling forces, I believe in proportion to the spin rate, slowing and scaling down the spiral. _However,_ the energy it takes to resist those forces comes from somewhere. In this case, it comes from the angular momentum, reducing the spin rate according to how strongly it resists unsettling moments.
So... in an idealized world with no random air movements and just the tiniest offset in the coin's initial angle or mass distribution (the graphics and lettering is more than enough for this), what should happen is that the coin will start in a very slow, small spiral, its spin energy being sapped as it resists the oncoming air flow (drag), making the spiral gradually increase in scale and speed. This will greatly reduce accuracy for your dastardly anti-New Yorker plan, and at some point the coin will reach a point where it's not aligned enough to maintain its spin, and will start to tumble, decelerating to the... what was it, 60 m/s that Mythbusters found?
In the _real_ world, the air wouldn't be still. Wind _speed_ won't change anything I don't think, other than to cause the coin's entire path to transform in that direction. Instead, it's _gusts_ i.e. _changes_ in wind velocity that will provide extra buffeting forces that will serve both to unbalance the coin and sap its angular momentum more quickly, and also decrease the threshold at which it will begin to tumble and slow down to the natural terminal velocity.
_As_ it spirals, it will also gain some lift, which will slightly decrease the terminal velocity, but this should be negligible as long as it's still spinning fast enough to stay within around 5° of vertical (simple small-angle approximation, thanks Trig!)
I... was considering attempting the calculations, but aerodynamic maths has a way of getting _really_ complicated, _really_ fast, and it doesn't take the removal of very many simplifying assumptions at all to make the differential equations unsolvable, requiring a numerical solution, which in turn requires very expensive software. This situation is more than complicated enough to be non-solvable by hand, and to require real, high-fidelity computational fluid dynamics, so... unless someone who has access to such software wants to give it a go, I'm afraid I'm limited to just gut instinct.
My instinct says that it's unlikely a real coin, dropped from a real building the height of the Empire State Building, in real atmosphere including potential buffeting and vortex shedding from the building itself, would actually keep spinning long enough to make it to the ground anything close to vertical. My gut says the spin rate you'd need to start with would be beyond the physical limits of the coin to hold together (assuming a modern composite coin; a bespoke 'coin' of a homogeneous and high tensile strength material maybe could do it). Actually, my instinct is that it won't even be _close_ to possible, and will probably slow enough to start to flutter and tumble within something like 5-6 seconds even at very high rate of spin.
Honestly, if you want to drop something from a tall building and have it be genuinely dangerous every time... try a dart. Or any rotationally symmetric, streamlined object, really. Or a rotationally symmetric object of any profile that's spin-stabilized, like, I dunno... a bullet? xD
A thin cylinder edge-on is actually pretty terrible in terms of drag coefficient, and the contours of the surface, and the slightly thicker ridge most coins have around the outer edge are non-trivial and make it even worse. I would only expect the speed to go up by a factor of 2 to _maybe_ 3, which does get it close to that 300 km/h people were finding using (presumably fairly basic) physics simulators.

Its less the weight, more that the apparatus blocked the sensor on the bottom which the Mini uses to detect obstacles. That's why you had issues lowering the drone - it tried to avoid the "Ground".
The problem with your assertion is that the Empire State Building is just shy of 1/4 mile tall at approximately 1250 feet... do you think you could throw a coin hard enough that it could travel perfectly straight on the "skinny" edge without the air resistance causing it to revert to the flat position it would revert to naturally?...
A spinning object doesn't spin indefinitely... especially if it has any force pushing against it...
Try shooting it into a wind force 1250 feet & see what happens...
For future reference; a crossbow is made much more tolerable if you build in a lever to pull the string back.
The speed calculation at the beginning may have been wrong because it didn't consider parallax. Parallax is when things closer appear to move faster than things further away. This is the same thing that means you can move your finger a few centimetres in front of your eye and it appear to move past the moon. Trigonometry or something.
That actually makes a lot of sense. Thank you.
Parallax is not intrinsically about speed. It affects an observers ability to accurately determine the speed of two objects at different distances. It also affects the ability to read a stationary analogue gauge l.
He could do some silly math to find the actual distance it traveled… but a chronograph is “easier”
he also didn't consider that framerate isn't necessarily the same as shutter speed, you can be shooting at 250 FPS and 1/500 shutter speed, that'd mean the shutter is only open for half a frame for every frame (1/500th of a second every frame), thus, whatever it appears to have travelled in one frame, is actually half of what it travelled during the frame-time
Actually he made a mistake as in his calculation his coin traveled 172 kmph while the fastest baseball pitch was 170 kmph (106 mph), and we know it's much easier to accelerate a small compact and aerodynamic metal object than a big soft baseball
I was gonna say how it's a wonder that the Australian government hasn't put him on a list yet, but he probably is on ALL the lists... it's just that he'd be an even bigger threat if they do anything so they just hoping one of his projects kill him without their effort.
Well, yeah, he might be dangerous but mostly just to himself. He also just seems like an open book.
Oh, he’s 100% on a list, with Friendly Jordies if nothing else.
i mean he did get in trouble for a few projects like his tampon gun so hes definitely on at least one
@@talanross9696Wait, explain??
Prison could not contain this man, he would simply use his razor whip to escape
"I don't want to make a gun in this video", procedes effectively make a gun
Flexispot desks are legit good stuff, lol. Glad to know it's rogue coin proof!
I feel like “I’m going to try to not make a gun” is this man’s mantra.
i hate when i’m making breakfast and accidentaly make a gun :/
Yeah I mean he's not American
me : mom i want want a piggy bank
mom : we have a piggy bank at home
the piggy bank at home : 11:37
LMAO NO WAY
The bgm and the expression on the 03:28 really giving me the vibe of fascinated vibe 😯
8:40 I was literally thinking that must be because they're pink color. U killed me, bro. 100% new fan
Imagining your sponsor exec/important business person being told in an email "you need to watch his video and see what he did to our desk during the ad read!" gives me great joy. I mean I'm sure they knew what you were going to do but imagining that they did not is way more fun.
They would have been extremely happy with his imaginative effort. I was impressed. It got me talking myself into thinking I actually want one.
Now I want to know how the Australian 50 cent coin stands up compared to the US half dollar or the original dollar coin. Those things are huge, but kind of hard to find nowadays. They're both completely circular though, so no odd angles.
The Australian fifty-cent coin (15.55 g) is heavier than the US half dollar (11.340 g) but way lighter than the old silver dollars (26.73 g) or Eisenhower dollars (22.68 g).
@@erikkennedy All of which are notably lighter than the heaviest legal tender coin made by a government Mint worldwide: The Canadian Million-dollar coin, which weighs in at approximately 100 kilos (220 lbs). But of course, that coin could kill you if it dropped on you from a hand's-width above your head, at any angle, so that's kinda cheating.
@@falsnamae3511 220 lbs is survivable. Not always, but people fall on their head trying to do a handstand, and that's (for some people) about 220 lbs coming down on your head from a hand's-width or so drop. I mean, it's *able* to kill you, for sure, and you said "could" so you're not wrong... I'm mostly replying because it occurred to me that there are adults that weigh 220 lbs and can thump their head with their body weight behind it and survive.
Also, Matthias Steiner dropped 432 pounds on his head and neck when he slipped while competing in weightlifting during the 2012 Olympics. He walked off afterwards -- to a hospital for imaging. I'd imagine he managed to at least slow it with his arms, but it is still impressive (don't look it up if you're squeamish). So therefore we need to test large Canadian coins on large Germans.
@@falsnamae3511 And then there's the 1 tonne Gold Kangaroo - plenty heavy enough to crush you without needed a drop height
And then theres my massive steel balls. That can kill with a single tbag
I love you man, the only thing that really makes me laugh
kudos to you using the 1933 King Kong soundtrack, a really nice touch!
10:50
Bro 💀
It’s true tho
I am a mythbusters fan and enjoy these kinda things. Mythbusters also ran into the updraft on the building. Heavy coins with spin was something I’m not sure they even tried. Great replication of the myth and excellent results.
To this day I can't decide if your alignment is chaotic neutral or chaotic evil 😂
My brother accidentally dropped a coin off the acrophobia ride at six flags theme park. His goal was to set it on his knee and see if it rose up as the ride fell down but he dropped it and it fell 200 feet onto someones head. The guy felt it and looked up but was uninjured
"I feel like I'm Palestinian" bro had NO right to say that 💀💀💀💀💀
Way too soon
14:13 aint no way bro just said i feel like the Palestinians
Lmao at knocking the chronograph off the table. Ahh man you kill me
Having this be the background music changes the feel of this video a lot.
I really feel like the drop from the Empire State Building would be long enough to lose the spin and make the coin start gliding on its flat face anyway. Maybe this specific coin is still heavy enough to pack a punch, but probably not go straight through a human skull.
So what you're saying is that we need to find a building at just the right height so that the spin is lost right after it hits the ground?
just spin it faster or something
It’s the same concept as of shooting a bullet with a gun. Even if you shoot a gun, the bullet will eventually slow down due to air friction and become non lethal.
@@xirenzhang9126
to spin it really, really fast you'd basically have to build a Coingun and be firing it downwards from the Building, which starts to drift out of falling and also is definitely no longer an accident.
something like those Foam Disc launchers, or Airsoft/Paintball guns. some very fast squash rollers.
@@ecard0 Absolutely. It's a bit counter-intuitive, but true.
"i was unable to destroy it" is the best endorsement a sponsor could ask for
Now buy a vending machine and launch coins into it at high enough speed to make it drop multiple things 😂😁
The flexispot is nice looking but inside the legs there is a weak spot, a plastic part on which all the weight rests. Mine failed. That being said, they immediately shipped me a new one after a semi frustrating video proving that it didn’t work. So they do stand behind their products.
They stand behind their product lmao
Pretty sure they stood on their product too.
@@RamoArtwitty advertisement!

14:12 "I feel like a palestenian"
bro way too fucking soon
My thoughts exactly, and then laughing at it…
It's not just soon, it's still currently happening
@@MolecularMachine just so insensitive and ignorant. And no one is talking about it
@@meryannaji1517 For what it's worth, the guy who said it is very much opposed to the crimes being inflicted on the Palestinian people right now. I doubt he meant anything bad with it. I agree it was in bad taste though.
made me unsubscribe immediately.
Enjoyed the casual swipe on the Yanks you made on the way through.
"I'm going to try not to make a gun this video!"
> makes a crossbow instead-
I love how you say your not gonna build a gun then also almost immediately proceed to build a crossbow for coins
a crossbow isnt a gun
He never ceases to amaze me with his own ways to showcase the sponsor's products
