Today's revelation: our standing desk not only aids in efficiency and health but also serves as a lifesaver (especially for your head)!

I like how ididathing videos always start with a scientific approach but just end with some life-threatening test that’s thrown together last minute

Not only did this video prove that falling coins could be lethal, we also saw the creation of the world's most realistic piggy bank

10:51 “I got a pig head. Which is similar in weight and size to most Americans heads.” peak comedy

I like how his fingernails have learnt to stop growing to protect themselves.

The scariest part about this man is that he is actually absolutely mad, yet he sounds so sane.

Mythbusters weren't wrong. They forgot the concept of continental drift, which helped make Australian animals and coins more deadly.

I just watched Basically Homeless make a beautiful invisible gaming PC with an expensive desk, then immediately watched Ididathing destroy the same desk with a 50c coin crossbow. What a time to be alive.

"I feel like a palestinian" is wild

hey m8, im finishing a phd in chem, and i gotta say, this was the closest to actual research-grade investigation you have ever done. you designed a hypothesis, performed background work, reported/published findings in a narrative that flows. stupendous shit m80.

I love that he said he didn't wanna make a gun, but then proceeds to use a spear gun 5 seconds later

He did not just say "i feel like a Palestinian" 💀💀💀

Whoever made the animation at the start DESERVES a raise

this guy is becoming more dangerous every video and i'm here for it

I appreciate you converting from "meters per second" to "school shooters per cheeseburger."

Him actually showing how durable and strong that standing table is impressed me more than any normal ad read ever could. It almost seems like it could make a suitable workbench and not just a pretty thing to have your PC on

in his attempts to not build a gun, he instead built a crossbow. the predecessor to the gun

"I wanna avoid making a gun" *MAKES A CROSSBOW*

I really like the positive encouragement for the young pianist.

"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 worlds cheapest terrorist attack” got me 💀

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.

When Aleksa said “I feel like a Palestinian” I legit slapped my hand over my mouth 😭💀

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.

I love how he basically made a crossbow, but took no inspiration from how crossbows are drawn back and struggled to pull it back every time

6:30 I like the little detail that he went from safety glasses to a full face shield out of fear xD

“I feel like a Palestinian” is crazy 💀

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"

You really made this "will a falling coin kill someone" as a front to making another deadly ranged weapon didn't you

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.

The fact you had more confidence in the desk shielding you instead of your car is insanely hilarious.

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"

You have a real gift for humor my friend, This is a fantastic channel to watch if you're having a bad day, it's almost like I have to watch your videos twice each because you'll make me laugh so hard I'll have to keep going back and rewatching parts lol. 6:00 I was so clenched the entire time you were pulling that back I thought it was gonna snap back and take off your head lmao!

I would love for Adam to see this and hear his reaction. Dude is a joy to listen to. He would love this video.

I love the realization you get at a certain point in almost every idat video of just “oh yeah, that random little thing he just cobbled together and is firing in his garage could kill a person effortlessly, that’s neat”

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.

14:19 THATS INSANE

I love the unhinged chaos of this channel as much as i love that he pretends everything is totally normal 😂😂😂

Alex sure knows how to do sponsor segments right. One of very few who can make me watch an ad and not instinctively be annoyed :)

i love how the premice of the video is just "yeah mythbuster did it but if it was me i'd be actually YEETING these coins with actual murderous intent" absolutely beautifull

Sometimes i get down on myself because i have tiny finger nails but then i come to this channel and i feel much better thanks!

This is a masterclass for OSHA. I wouldn't be surprised to see you teaching the advanced safety course.

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.

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.

Him grinding his finger was one of the most characteristic moments in this video for him🤣

great video as ever! the reason the drone goes doesnt come down with the dropping device attached is because the device covers or ubstructs the height measuring camera or sensor. i dropped some water balloon from my freinds mavic mini with a similiar servo bomb dropped and the same thing happened

Mythbusting Mythbusters seems like a fun series, although I fear it maybe a short run series.

i like how it takes a few videos to realize that he's actually a good engineer not just a random dude doing crazy contraptions with no experience

Homeless man: you have anny spare change? Me: 1:33

"General, I just made a new weapon for the Australian army" "How much are the bullets?" "Ahh... About fifty cents" "Excellent. We won't shoot our enemy, We'll monetize them!"

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.

As silly as it might sound, the type of content that this channel produces has a 100% hit ratio for reinvigorating my passion for physics and engineering.

came back this channel two years after not watching it, i did not exepect it to change so much.

This is by far the funniest and best sponsor ad I've ever seen 😂 more companies need to sponsor this guy!

Flexispot knew who they were dealing with when they sent over the desk lmao

There was no spoilers, you showed the building side, the trials and errors, with hilarious adult humour and final results. This was perfect. Thank you for the entertainment.

Thanks for the video. I have to say that the coin would still stay mostly upright due to drag forces pushing it into it's most aerodynamic position, which is when it's upright, so you don't have to put a spin on it when it travels fast enough.

The amount of power hiding in that garage is terrifying.

You did what everyone else in youtube is too afraid to do. Bringing back pig carcasses as human analog in deadly experiments. Thank you for this gift.

This man is living proof that pain compliance is not a reliable form of self defense. He clearly experiences human discomfort at a much lower level than most, and could almost certainly continue to attack you as you taze him directly in the balls.

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.

been watching for ages and it's kind of wholesome watching your little sibling grow up with your channel lmao

I absolutely knew what would happen to the chronograph the second he started punching through the gate. The speed of that thought to reality was certainly very quick!

Camera man’s commentary was deadly. I love this guy.

he picks the most random subjects for videos, i love it

I appreciate him going through the process of flipping the video upside down for us here in America.

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...

"I don't want to make a gun in this video", procedes effectively make a gun

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.

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.

Flexispot desks are legit good stuff, lol. Glad to know it's rogue coin proof!

The bgm and the expression on the 03:28 really giving me the vibe of fascinated vibe 😯

I feel like “I’m going to try to not make a gun” is this man’s mantra.

me : mom i want want a piggy bank mom : we have a piggy bank at home the piggy bank at home : 11:37

For future reference; a crossbow is made much more tolerable if you build in a lever to pull the string back.

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.

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.

kudos to you using the 1933 King Kong soundtrack, a really nice touch!

I love you man, the only thing that really makes me laugh

10:50 Bro 💀

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 💀💀💀💀💀

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.

"i was unable to destroy it" is the best endorsement a sponsor could ask for

Enjoyed the casual swipe on the Yanks you made on the way through.

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.

14:12 "I feel like a palestenian" bro way too fucking soon

"I'm going to try not to make a gun this video!" > makes a crossbow instead-

Now buy a vending machine and launch coins into it at high enough speed to make it drop multiple things 😂😁

I love how you say your not gonna build a gun then also almost immediately proceed to build a crossbow for coins

He never ceases to amaze me with his own ways to showcase the sponsor's products
