This photo looks heavily distorted but if you calculate the windows its 7th maybe 8th floor, so not more than 24m/75ft. This alone is survivable given the pool is deep enough as professional athletes do jumps over 50m/170ft
I do however doubt this pool is deep enough, so when you'll probably survive the water impact (assuming you know how to do these jumps), you'll probably still crash into the pools floor
Shallow diving is the sport that consists in jumping from the highest place into the shallowest pool. To put it in context, the records are:
- 11.52 m (37.8ft) into 30cm (1ft) depth
- 24m (80ft) into 1.2m (4ft) depth
- 33.5m (110ft) into 2.4m (8ft) depth
Since the pool is probably deeper than 1.2m, I'd say it's survivable (with training), even though not advisable.
Because, while it is true that surface tension can make water behave like a solid at high energy impacts, that is true if you hit the water belly first.
The technique for shallow diving is this: to avoid hitting the bottom of the pool, you have to hit the water with the higher surface possible, so they belly flop. To avoid the resistance surface tension makes, and avoid injury like a normal belly flop would cause, they tilt their arms so that the hands are the first to enter the water. In this way, you use all the surface possible to slow you down, but you don't use it in the same instant but "gradually" (for a definition of gradually that spans milliseconds) radiating from the hands so that you disrupt the surface tension and basically still pierce the surface like a needle.
Oh very much thanks!
It's the first time on reddit I am that person. Usually I'm the one mesmerized by people like this.
I just had a Guinness World Record book as a child and knew it by heart, and since I'm a big science nerd i couldn't possibly live without knowing how they did it
Youtube link for those as curious as me:
[https://www.youtube.com/watch?v=Qc25Ewq9QBI](https://www.youtube.com/watch?v=Qc25Ewq9QBI)
Absolutely bonkers, guy's basically jumping off a 4-story building into a kiddie pool.
I'd argue that's still upwards of 30 times more than if you dove on concrete, so 30 times less "instantaneous" force applied to your body, which is ultimately what kills you in an impact.
Provided you have good technique and use the full 30 cm to cushion your fall, which is indeed an insane feat.
Yeah, I was curious what’s under the pool and I assume that is held standard too. I mean, you could put an airbag under there and survive from much higher just landing on your back.
Records (at least in this category) don't count if they don't survive.
The man who broke the first record is still alive and well today, the other two died but because they were born in the late 1800s. They were circus stuntmen, in the Golden Age for circus. The second one died at 90, 15 years after his last exhibition of reasons unrelated to his job, the third one died during a performance which, you guessed, didn't count for the record. It was aptly called the "Dive of death"
I think the absurdity of the stunt would be better known than the details. Especially if it gets out that the stunt was inspired by a comment thread on Reddit
> What the record for people who don’t survive?
If you mean "fell whist alive but died on impact with the water" - about 65 thousand feet, the peak altitude reached by the crew cabin of the Challenger shuttle on its final flight.
All you need is some cocaine. Here's argentinian rockstar Charly Garcia jumping from a 7th floor: [https://www.youtube.com/watch?v=4urTQx1-Rfo](https://www.youtube.com/watch?v=4urTQx1-Rfo).
I think that's the key. Is it feasibly possible to do? Certainly, I've seen higher jumps into shallower water. Would the average person survive? Doubtful. They'd maybe survive but not without injury
I'd say about 10 stories. Still well below the world record of 58.5m, but this pool is surly too shallow. Even at half the height you want at least 10m of water.
Yep. I’m seeing at least 9 or probably 10 windows. And even then it looks like there might be a floor or two as orange and green looks like a roof or at least covering which would have a base floor under it.
I remember a fire Marshall telling us, if a building is on fire and jumping out a window is the only choice... jumping out of 4th floor window gives you about 50% chances of surviving. Surviving... not walking way. And that an 8th floor jump was the maximum height you could jump and hope to survive, with about 10% survival rate. And I clearly remember him saying that for a 4th floor jump, aiming for car, trashcan, pool etc would increase your odds, but on the 8th floor, unless you are jumping on a professional stuntman landing zone, there is nothing you can "fall on" that will help, not mattresses piled really high, not a pool, not a lake.
I didn't see anyone else pointing this out, so: the image is misleading (and even being there in person it probably is). There is a VERY substantial horizontal distance between that window and the pool. Even if you could survive dropping straight down into the pool, you are very likely not to make it there, and smack into the concrete (or perhaps that green/yellow part that I assume is an entry-way roof).
It's super easy to over-estimate how much vertical distance you will cover in free-fall, because the ground you're measuring against is at a distance. But it looks like 10-20 ft. easy.
Anthony Kiedis of the Red Hot Chili Peppers, in his autobiography, writes about jumping into apartment complex pools from the roof of the building in LA. His explanation of how he and his friends did it, as I recall, was to basically jump feet first, but immediately push your legs sideways and turn horizontal as you hit the surface of the water in order to sort of transfer the momentum sideways rather than down.
I could sort of see this working from a few metres, but in the context he was talking, I always thought it was bullshit (from several floors up? Nah.).
With that said, none of the comments here have mentioned taking an approach like that; could anyone more informed than I on physics give any insight into whether there’s any chance of Kiedis’ method working?
(Worth pointing out as an aside, Kiedis also mentions breaking his back doing this, but only because he missed the pool one time…).
If people here are correct and the height is about 20 meters, you'd hit the water at 70km/h. If the technique is wrong that's enough to kill you. The pool will likely be too shallow to fully stop you without any damages. It's possible to survive if there's enough water but very unlikely.
I’ve heard that without being a professional diver, around 75ft is equivalent to hitting concrete? Could be an old wives tale or something, but I wouldn’t fuck with anything over like 20ft personally lol
Yea, I vaguely recall a mythbusters episode of them dropping a dummy at certain heights and found that eventually the water can’t get out of the way of the body fast enough, so splat.
That being said idk if it would be a belly flop type of hit, or if even a pencil dive would be lethal too?
IANAPD...
However I've jump from pools 10m high (around 33ft)
I ve made the worst landings: open arms, face first, and the worst of all when you don't close your legs properly and the water hits you in the balls... 0/10 do not recommend.
However, I've never broken anything at that height, and it wasn't painful enough to keep me from doing it again.
My record is 12m, fear stoped me from jumping from the 18m platform.
My reckless, savage friends did jump. No one got hurt, yes you end up bruised, like you receive a massive body-size slap
People have survived falling out of planes without parachutes and landing on dirt.
It's happened, the chances of survival are extremly low.
So yes, it's possible someone would be survive falling what appears to be 8 stories into a normal depth swimming pool, however it's unlikely.
Probably not. Not exact math here but,
Looking at the image we see that we are about 8 stories off the ground. In 2005 there was a study done that found that falls of 8 stories or higher were 100% fatal(out of a sample size of 287).
This didn't consider water, but at high speeds the surface tension of water will make it hit like concrete. So you're most likely dead unless you land in a particular way that happened to break surface tension before most of your body hits the water, but even in this case it depends on the depth of the water, so your chances aren't looking good.
Sadly Minecraft physics lied to us all
They tested this on Mythbusters and even dropped a hammer to break the surface tension just before the dummy hit the [water.](https://youtu.be/oCSQExxWulU)
Charly García, Argentinian singer, trew himself to a pool from a 9th floor like 10 years ago, and survived. Here's the video:
https://www.youtube.com/watch?v=-oG9yWHRW1k
In burn notice, one episode they had to jump out of a hotel room to the pool, they threw a mattress on the pool to further increase chances of survival. I think the myth busters tried it out and i think it did work.
Interesting, I wonder if hitting a matress would make things better or worse for the layman.
From the comments about shallow diving, it sounds like that technique (basically a belly flop but with arms hitting the water first) is the safest if executed well, and hitting a matress would almost certainly cause more injury than that.
But simply landing feet first / pencil dive would likely be safer hitting a matress floating on the water, than landing in a shallow pool and smashing against the bottom. You might still break your legs hitting the matress, I really don't know, but I'm guessing it wouldn't sink very much or very quickly into the water, so you don't have much more than the matress itself to absorb the impact.
At least not for a traditional matress, I'm guessing the newer foam ones would both deform more thus absorbing more energy, and displace into the water more.
So then the question is, is it better to try to hit a matress feet-first (seems most fool-proof / reliable way to achieve survival, with likely injuries), or belly flop on the matress (possibly fewer injuries, but greater chance of lethal injury), or attempt the shallow diving technique of hitting the water (highest risk of dying if you fail, but also most effective way to walk away with zero injuries if you pull it off.
I find this oddly fascinating. As unlikely as I ever am to need to jump off a roof into a swimming pool, I'm even less likely to find myself in a situation where I have a matress available and capable of tossing it the swimmer pool! Matresses are heavy, and if I can even manage to get it through a window (or more likely over a patio), it's going to fall straight down. There's no way I'm throwing that any horizontal distance.
edit: I missed the part about Mythbusters testing this. I'm going to have to lookup which episode that is, it might answer some of these questions.. I found a very brief clip and it does look like the matress sunk into the water a decent amount (nearly two feet), so it does seem like that helps a lot.
The burn notice episode was about surviving jumping into a semi-shallow pool, so that is what the mythbusters were testing. The impact was actually worse with the mattress and it was possible to dive into the pool and not hit the bottom.
https://mythresults.com/cannonball-chemistry
Edit: typo
In fact someone jumped from that window into the pool and survived. That photo was taken from the window through which one of the most loved and recognized musicians in Argentina "Charly Garcia" jumped.
There's a Mythbusters episode somewhere probably on YouTube talking about how water turns to concerte at a certain height... I'm not sure the correct height but with all the lens fair I assume he's on his roof fence the bricks next to him, I'm going with yes without bricks next to you per say up to 4 floors plus that's a no.
Mythbusters did an episode about this topic. A very specially trained person maybe could, but with a very low survival rate. As a normal person you prob have a higher chance jumping into a tree from that height
Absolutely! It’s all about technique—bad technique can get you killed (landing on neck/head), good technique say from an Olympic diver will be fine. Per Wikipedia “In 1983 Wide World of Sports produced its last World Record High Dive at Sea World in San Diego. Five divers (Rick Charls, Rick Winters, Dana Kunze, Bruce Boccia, and Mike Foley) successfully executed dives from 52 metres (172 ft).” Other comments estimate 8-10 story height in the image; if we assume that a story is under 5 meters/15 feet tall (which is definitely a reasonable assumption), it is a survivable drop.
https://en.m.wikipedia.org/wiki/High_diving
Go check out 8booth on YouTube. He has a bunch of videos labeled "Pool drop" of him jumping into hotel pools from the roof...maybe not this high but close. Also he absolutely shattered both his legs on one of them.
Well, the only force that would be acting on the person who fell would be the viscous force, which is slightly difficult to compute but let's assume for our convenience that the person in question is plump and rotund and has a huge pot belly, and is short, so that we may assume him to be a sphere. Viscous force=6π.n.vr.
The greatest force a human has ever survived is estimated to be slightly above 9kgf. That building easily has fifteen stories, so I'll assume its height to be 60m.
F= 2933 N. So nah. Our fatso dies.
So I've not seen anyone do the math so I will
Using kinematics equations we assume jumping and a constant acceleration of 9.8m/s^2 we can get final speed using
Vf^2 = vi^2 + 2ad
A = acceleration due to gravity at 9.8 m/s^2
D = an estimated 100ft (~30.5m) found by counting windows I got roughly 10 and standard floors are roughly 10ft tall including space for ductwork etc.
Vi = 0 since we are jumping and out initial v in the downward direction can be assumed to be 0 and we can treat it like free fall at that point
Plug and chug we get
Vf^2 = 0^2 + 2*9.8*30.5
Vf = √597.8
Vf = 24.45m/s or about 54.6 miles per hour
So would hitting the water instantaneously kill you surprisingly no. It actually turns out water is still compressible enough to not instantaneously kill you until you reach speeds upwards of 50m/s and we're still just under half that so now survivability will depend on your aim, the depth of the pool, and your diving form. So long as you actually hit the water feet first with good form all around odds are good the initial impact won't be deadly.
That said the depth of the pool now has a pretty significant impact on this equation and fluid dynamics are actually pretty complicated but if we assume that you are traveling at about 54mph and that you now have only 10ft or so of distance to go from 54mph to 0mph that leaves us to attempt to approximate force and see if that is immediately deadly.
Assuming the work done on ourselves is roughly equal to the kinetic energy generated we get
Now we have Work = force * distance = 1/2mv^2
So solving for force we get
Mass = average 80kg
V = vf = 24.45m/s
D = 10ft
F = (.5 * 80 * 24.45^2 ) / 10
F = 2391 Newtons
Which is surprisingly not quite high enough to guarantee instant death. So now it depends almost entirely on impulse so how we land and how much we are able to spread out that force across our body and more specifically how long we are able to stretch out the time it takes for our body to experience that force as we become submerged.
Which is really really complicated because how you land and what parts of your body make contact with the water for the shortest time at the highest speeds as well as how well you crumple as you hit the bottom and all of that is WAY too complex even for me to bother with at 2am.
So can a person jumping from that g
Hight actually survive the fall astoundingly yes it's actually possible it's going to hurt like a bitch and almost certainly do some serious damage but it's actually survivable. Nothing about this heigh is guaranteed death it's still pretty likely and odds of WALKING away are slim but it can be done.
Which is backed up by further evidence that people jump from 200-300ft drops and live all the time this is only 100ft and although not at ALL recommended it's not deadly at all with decent form and sufficiently deep water. Obviously I have no way to know the depth of this pool so I was just guessing but it's cool that instant death even though it seemed completely assured is not a guarantee which is neat :)
......Well that is assuming my math is right but I am CONFIDENT Reddit will let me know if I managed to miss something 😅🤣
[Here is an interesting read on fall height survivability.] (https://link.springer.com/article/10.1007/s00068-017-0799-1#:~:text=Historically%2C%20the%20median%20lethal%20dose,ft%20%5B2%2C%206%5D.)
I've seen the LD50 fall height listed as between 30-40 ft in a number of studies, but it is clear that a fall from any height can be fatal. Similarly, a fall from any height can be survivable, as shown by rare cases of people surviving falls of 10,000 ft or more from airplanes.
Most of the falls in these studies are onto ground, not water. Falling on water has advantages and disadvantages over falling on ground. Advantage: Water is not as hard as most types of ground, but thanks to surface tension it's still very hard when you hit it at high speeds. Disadvantage: if you survive the fall, but are incapacitated, you're much more likely to drown in water than on ground.
So an uncontrolled fall of about 80 feet into a pool is survivable, but your odds are low (much less than 50/50), especially if there's no one down there to pull you out. All of this assumes you aren't a [specially trained high diver.](https://en.m.wikipedia.org/wiki/High_diving)
Unlikely
Depending on the height, surface tension will make the water behave like solid ground, don't know how high this one is though
Besides that, the kinetic energy you'll gain from such a fall will be so great that you'll hit the bottom of the pool almost like the water wasn't there if the pool isn't deep enough
No, over 20-30ft hitting water is the same as cement. The only way you could survive is if the pool was super deep and you went in foot first even then I think this spot is too high up
I don’t need to do the math to say no… no they won’t.
Hitting the water probably won’t be much softer than hitting the concrete and the pool doesn’t look that deep.
Then again people have survived being sucked out of a plane while flying and falling with no parachute.
Depends on how deep the pool is. Id doubt it would be any deeper than 12 feet. Even if its 12 feet deep its definitely not deep enough for that high of a fall
Not counting for pool depth and if you would hit the bottom because others already calculated it, hitting the water a certain way can act more like a solid
There are professional shoe divers that dive into like 6 feet pools from 100ft. I think *professional* is the key word here. But if this is you only way out, I’d say it’s better than concrete
It doesn’t look high enough that the air resistance would start to kill you, but you’d build enough speed so that hitting the water will be like hitting concrete.
Pool also doesn’t look that deep, so there’s that. Would like to see the maths

What's funny is they're both right. Second guy just wants to be an ass about it. Surface tension is due to molecular bonding, increasing density.
I hope it’s the drugs because that isn’t in depth knowledge of anything.
Youtube link for those as curious as me: [https://www.youtube.com/watch?v=Qc25Ewq9QBI](https://www.youtube.com/watch?v=Qc25Ewq9QBI) Absolutely bonkers, guy's basically jumping off a 4-story building into a kiddie pool.
Are we ignoring the "30cm deep" part here? I get that this technique might help when the water is deeper. But 30cm doesn't give a lot of wiggle room.
Hence why it’s record worthy.
Sounds like someone survived an attempted suicide and they gave them a record for it.
That's still similar to (or often more than) the travel distance when an airbag saves you in a car crash at similar speeds.
I'd argue that's still upwards of 30 times more than if you dove on concrete, so 30 times less "instantaneous" force applied to your body, which is ultimately what kills you in an impact. Provided you have good technique and use the full 30 cm to cushion your fall, which is indeed an insane feat.
You can still hit the bottom too, just not at full speed
So if I'm reading this correctly, shallow divers are basically just doing the worm when they hit the water to avoid dying?
[удалено]
Every time someone uses “surface tension” in this topic it’s a misunderstanding for “incompressibility” lol
It is not the surface tension. If it were true, small amount of soap would solve the problem. It is instead inertia and incompressibility of water.
thank you for the explanation! I didn't know this
You basically bellyflop in a specific way. If I recall correctly, the record holder broke 2 ribs during this, but I might be wrong
https://youtu.be/Qc25Ewq9QBI
i'm very relieved to see it's an inflatable pool against a crash pad and not just a regular tile/concrete pool they're jumping into
Yeah, I was curious what’s under the pool and I assume that is held standard too. I mean, you could put an airbag under there and survive from much higher just landing on your back.
I saw a dude fall 11 meters onto the sidewalk and limp off on an episode of cops. He was hiding outside an apartment window.
Drugs are one hell of a drug
Did the record holders survive or just died after they did the record ?
Records (at least in this category) don't count if they don't survive. The man who broke the first record is still alive and well today, the other two died but because they were born in the late 1800s. They were circus stuntmen, in the Golden Age for circus.

What the record for people who don’t survive? Can I do a felix baumgartner jump into a kiddie pool, die, and hold a world record?
I think the absurdity of the stunt would be better known than the details. Especially if it gets out that the stunt was inspired by a comment thread on Reddit
Considering that technically the shallowest pool is 0m deep, trying to get this record would put you on a really tragic list of people.
not necesarily. the record can be 1cm high. From there, maybe up to several meters you can do without any damage.
You get a Darwin's prize if you are lucky not to have kids, else you get nothing 😜
> What the record for people who don’t survive? If you mean "fell whist alive but died on impact with the water" - about 65 thousand feet, the peak altitude reached by the crew cabin of the Challenger shuttle on its final flight.
I would’ve thought they were cremated. Were body parts recovered?
I mean someone has probably jumped off a plane in a puddle and died, but we don't regard it as a record

Yep. I’m seeing at least 9 or probably 10 windows. And even then it looks like there might be a floor or two as orange and green looks like a roof or at least covering which would have a base floor under it.
When real life physics doesn't work like in Minecraft
I remember a fire Marshall telling us, if a building is on fire and jumping out a window is the only choice... jumping out of 4th floor window gives you about 50% chances of surviving.

Even if the mattresses were piled say 7 stories high?
So, survivable but likely in a vegetative state going forwards?
I didn't see anyone else pointing this out, so: the image is misleading (and even being there in person it probably is). There is a VERY substantial horizontal distance between that window and the pool. Even if you could survive dropping straight down into the pool, you are very likely not to make it there, and smack into the concrete (or perhaps that green/yellow part that I assume is an entry-way roof). It's super easy to over-estimate how much vertical distance you will cover in free-fall, because the ground you're measuring against is at a distance. But it looks like 10-20 ft. easy.

I've done a jump from about 60ft before. I could see this being done and working from a 7th or 8th floor, albeit with some pain...
The real question is if the pool is deep enough
Yes!
they also used singing to propel themselves through the elements
If people here are correct and the height is about 20 meters, you'd hit the water at 70km/h. If the technique is wrong that's enough to kill you. The pool will likely be too shallow to fully stop you without any damages. It's possible to survive if there's enough water but very unlikely.
Sounds like a fun time. 'Yeah, you'll survive the *fall*, but good luck drowning at the bottom of the pool with half your bones broken'
For a random person that is, but trained individuals could easily do this without getting harmed
How did you get that speed btw
V=square root(2hg) V is the speed in m/s H is the initial height in meters(20) G is gravity attraction (9.8m.s)
Oh thanks I thought I was doing something wrong but I didn't read the units in your first comment lol
I’ve heard that without being a professional diver, around 75ft is equivalent to hitting concrete? Could be an old wives tale or something, but I wouldn’t fuck with anything over like 20ft personally lol
That's what I was thinking. Fall fast enough you're hitting that water like it's concrete.
Yea, I vaguely recall a mythbusters episode of them dropping a dummy at certain heights and found that eventually the water can’t get out of the way of the body fast enough, so splat. That being said idk if it would be a belly flop type of hit, or if even a pencil dive would be lethal too?
I feel like a "pencil dive" would pierce the water but idk.
It would, but unless it's an olympic diving pool you'd just hit the bottom
IANAPD... However I've jump from pools 10m high (around 33ft) I ve made the worst landings: open arms, face first, and the worst of all when you don't close your legs properly and the water hits you in the balls... 0/10 do not recommend. However, I've never broken anything at that height, and it wasn't painful enough to keep me from doing it again. My record is 12m, fear stoped me from jumping from the 18m platform. My reckless, savage friends did jump. No one got hurt, yes you end up bruised, like you receive a massive body-size slap
People have survived falling out of planes without parachutes and landing on dirt. It's happened, the chances of survival are extremly low. So yes, it's possible someone would be survive falling what appears to be 8 stories into a normal depth swimming pool, however it's unlikely.
How could they survive a fall out of a plane like that? Do they get super lucky and the trees catch them or what?
Yes. https://en.m.wikipedia.org/wiki/Juliane_Koepcke
https://en.m.wikipedia.org/wiki/Highest_falls_survived_without_a_parachute
Probably not. Not exact math here but, Looking at the image we see that we are about 8 stories off the ground. In 2005 there was a study done that found that falls of 8 stories or higher were 100% fatal(out of a sample size of 287). This didn't consider water, but at high speeds the surface tension of water will make it hit like concrete. So you're most likely dead unless you land in a particular way that happened to break surface tension before most of your body hits the water, but even in this case it depends on the depth of the water, so your chances aren't looking good. Sadly Minecraft physics lied to us all
Damn, I’m thankful I didn’t sign up for that study
People have survived jumping from the Golden Gate Bridge, a 20-story drop into water. Survivable, but unlikely.
They tested this on Mythbusters and even dropped a hammer to break the surface tension just before the dummy hit the [water.](https://youtu.be/oCSQExxWulU)
Charly García, Argentinian singer, trew himself to a pool from a 9th floor like 10 years ago, and survived. Here's the video: https://www.youtube.com/watch?v=-oG9yWHRW1k
Look up Argentina's musician Charly García. Once he did this in an hotel room, escaping the police knocking on the door. He was high as fuck.
only if you do enough drugs beforehand... charly garcia, the absolute legend did it in '00 in argentina https://www.youtube.com/watch?v=-oG9yWHRW1k
In burn notice, one episode they had to jump out of a hotel room to the pool, they threw a mattress on the pool to further increase chances of survival. I think the myth busters tried it out and i think it did work.
Interesting, I wonder if hitting a matress would make things better or worse for the layman. From the comments about shallow diving, it sounds like that technique (basically a belly flop but with arms hitting the water first) is the safest if executed well, and hitting a matress would almost certainly cause more injury than that. But simply landing feet first / pencil dive would likely be safer hitting a matress floating on the water, than landing in a shallow pool and smashing against the bottom. You might still break your legs hitting the matress, I really don't know, but I'm guessing it wouldn't sink very much or very quickly into the water, so you don't have much more than the matress itself to absorb the impact. At least not for a traditional matress, I'm guessing the newer foam ones would both deform more thus absorbing more energy, and displace into the water more. So then the question is, is it better to try to hit a matress feet-first (seems most fool-proof / reliable way to achieve survival, with likely injuries), or belly flop on the matress (possibly fewer injuries, but greater chance of lethal injury), or attempt the shallow diving technique of hitting the water (highest risk of dying if you fail, but also most effective way to walk away with zero injuries if you pull it off. I find this oddly fascinating. As unlikely as I ever am to need to jump off a roof into a swimming pool, I'm even less likely to find myself in a situation where I have a matress available and capable of tossing it the swimmer pool! Matresses are heavy, and if I can even manage to get it through a window (or more likely over a patio), it's going to fall straight down. There's no way I'm throwing that any horizontal distance. edit: I missed the part about Mythbusters testing this. I'm going to have to lookup which episode that is, it might answer some of these questions.. I found a very brief clip and it does look like the matress sunk into the water a decent amount (nearly two feet), so it does seem like that helps a lot.
The burn notice episode was about surviving jumping into a semi-shallow pool, so that is what the mythbusters were testing. The impact was actually worse with the mattress and it was possible to dive into the pool and not hit the bottom. https://mythresults.com/cannonball-chemistry Edit: typo
In fact someone jumped from that window into the pool and survived. That photo was taken from the window through which one of the most loved and recognized musicians in Argentina "Charly Garcia" jumped.
Vine a comentar lo mismo jajaja, no te leí antes
There's a Mythbusters episode somewhere probably on YouTube talking about how water turns to concerte at a certain height... I'm not sure the correct height but with all the lens fair I assume he's on his roof fence the bricks next to him, I'm going with yes without bricks next to you per say up to 4 floors plus that's a no.
I'll just leave this here https://youtu.be/E408JigEcFI Free karma summarise the video 😂
Mythbusters did an episode about this topic. A very specially trained person maybe could, but with a very low survival rate. As a normal person you prob have a higher chance jumping into a tree from that height
Hitting the pool won't do shit for your survivability. You *might* survive, albeit with many broken bones, but it's very, *very* unlikely.
Also drowning
I mean, it obviously will.
Absolutely! It’s all about technique—bad technique can get you killed (landing on neck/head), good technique say from an Olympic diver will be fine. Per Wikipedia “In 1983 Wide World of Sports produced its last World Record High Dive at Sea World in San Diego. Five divers (Rick Charls, Rick Winters, Dana Kunze, Bruce Boccia, and Mike Foley) successfully executed dives from 52 metres (172 ft).” Other comments estimate 8-10 story height in the image; if we assume that a story is under 5 meters/15 feet tall (which is definitely a reasonable assumption), it is a survivable drop. https://en.m.wikipedia.org/wiki/High_diving
Go check out 8booth on YouTube. He has a bunch of videos labeled "Pool drop" of him jumping into hotel pools from the roof...maybe not this high but close. Also he absolutely shattered both his legs on one of them.
Well, the only force that would be acting on the person who fell would be the viscous force, which is slightly difficult to compute but let's assume for our convenience that the person in question is plump and rotund and has a huge pot belly, and is short, so that we may assume him to be a sphere. Viscous force=6π.n.vr. The greatest force a human has ever survived is estimated to be slightly above 9kgf. That building easily has fifteen stories, so I'll assume its height to be 60m. F= 2933 N. So nah. Our fatso dies.
So I've not seen anyone do the math so I will Using kinematics equations we assume jumping and a constant acceleration of 9.8m/s^2 we can get final speed using Vf^2 = vi^2 + 2ad A = acceleration due to gravity at 9.8 m/s^2 D = an estimated 100ft (~30.5m) found by counting windows I got roughly 10 and standard floors are roughly 10ft tall including space for ductwork etc. Vi = 0 since we are jumping and out initial v in the downward direction can be assumed to be 0 and we can treat it like free fall at that point Plug and chug we get Vf^2 = 0^2 + 2*9.8*30.5 Vf = √597.8 Vf = 24.45m/s or about 54.6 miles per hour So would hitting the water instantaneously kill you surprisingly no. It actually turns out water is still compressible enough to not instantaneously kill you until you reach speeds upwards of 50m/s and we're still just under half that so now survivability will depend on your aim, the depth of the pool, and your diving form. So long as you actually hit the water feet first with good form all around odds are good the initial impact won't be deadly. That said the depth of the pool now has a pretty significant impact on this equation and fluid dynamics are actually pretty complicated but if we assume that you are traveling at about 54mph and that you now have only 10ft or so of distance to go from 54mph to 0mph that leaves us to attempt to approximate force and see if that is immediately deadly. Assuming the work done on ourselves is roughly equal to the kinetic energy generated we get Now we have Work = force * distance = 1/2mv^2 So solving for force we get Mass = average 80kg V = vf = 24.45m/s D = 10ft F = (.5 * 80 * 24.45^2 ) / 10 F = 2391 Newtons Which is surprisingly not quite high enough to guarantee instant death. So now it depends almost entirely on impulse so how we land and how much we are able to spread out that force across our body and more specifically how long we are able to stretch out the time it takes for our body to experience that force as we become submerged. Which is really really complicated because how you land and what parts of your body make contact with the water for the shortest time at the highest speeds as well as how well you crumple as you hit the bottom and all of that is WAY too complex even for me to bother with at 2am. So can a person jumping from that g Hight actually survive the fall astoundingly yes it's actually possible it's going to hurt like a bitch and almost certainly do some serious damage but it's actually survivable. Nothing about this heigh is guaranteed death it's still pretty likely and odds of WALKING away are slim but it can be done. Which is backed up by further evidence that people jump from 200-300ft drops and live all the time this is only 100ft and although not at ALL recommended it's not deadly at all with decent form and sufficiently deep water. Obviously I have no way to know the depth of this pool so I was just guessing but it's cool that instant death even though it seemed completely assured is not a guarantee which is neat :) ......Well that is assuming my math is right but I am CONFIDENT Reddit will let me know if I managed to miss something 😅🤣
[Here is an interesting read on fall height survivability.] (https://link.springer.com/article/10.1007/s00068-017-0799-1#:~:text=Historically%2C%20the%20median%20lethal%20dose,ft%20%5B2%2C%206%5D.) I've seen the LD50 fall height listed as between 30-40 ft in a number of studies, but it is clear that a fall from any height can be fatal. Similarly, a fall from any height can be survivable, as shown by rare cases of people surviving falls of 10,000 ft or more from airplanes. Most of the falls in these studies are onto ground, not water. Falling on water has advantages and disadvantages over falling on ground. Advantage: Water is not as hard as most types of ground, but thanks to surface tension it's still very hard when you hit it at high speeds. Disadvantage: if you survive the fall, but are incapacitated, you're much more likely to drown in water than on ground. So an uncontrolled fall of about 80 feet into a pool is survivable, but your odds are low (much less than 50/50), especially if there's no one down there to pull you out. All of this assumes you aren't a [specially trained high diver.](https://en.m.wikipedia.org/wiki/High_diving)
Unlikely Depending on the height, surface tension will make the water behave like solid ground, don't know how high this one is though Besides that, the kinetic energy you'll gain from such a fall will be so great that you'll hit the bottom of the pool almost like the water wasn't there if the pool isn't deep enough
No, over 20-30ft hitting water is the same as cement. The only way you could survive is if the pool was super deep and you went in foot first even then I think this spot is too high up
I don’t need to do the math to say no… no they won’t. Hitting the water probably won’t be much softer than hitting the concrete and the pool doesn’t look that deep. Then again people have survived being sucked out of a plane while flying and falling with no parachute.
Depends on how deep the pool is. Id doubt it would be any deeper than 12 feet. Even if its 12 feet deep its definitely not deep enough for that high of a fall
Not counting for pool depth and if you would hit the bottom because others already calculated it, hitting the water a certain way can act more like a solid
There are professional shoe divers that dive into like 6 feet pools from 100ft. I think *professional* is the key word here. But if this is you only way out, I’d say it’s better than concrete
It doesn’t look high enough that the air resistance would start to kill you, but you’d build enough speed so that hitting the water will be like hitting concrete. Pool also doesn’t look that deep, so there’s that. Would like to see the maths
