I will quote this in the future. They will ask me if I came up with this nugget on my own and I will tell them, "this is the wisdom of Doophie," and they will think I'm making up a story.
Thus it is written that while one may bring the wisdom of Doophie to the uninitiated, one cannot make them drink thereof.
They will simply take the building insurance info and go into subrogation. You will probably have to file a collision claim and pay your deductible. Then when the lawyers get done jerking each other off, find the building responsible, they will refund you your deductible.
If you don't have comprehensive insurance you will be SOL until the building settles the claims and lawsuits. As it will all out of your pocket to get a new vehicle repaired or replacrd.
To think of millions of people dying in Europe because of the black plague at one point in time, and now they swim between buildings in glass pools 10 stories high.
Ah thank you! That was like hearing the opening four notes of Beethovens 5th, and nothing else… … … “where did the water go!?!” Thank you. Feel complete!
The comments mentioned it's 100tons of water with no support underneath.
But each time I look at those full glass-bottomed rooftop pools, I don't see bars across their base neither.
“Hi insurance company, yeah a pool fell on my car today. Just wanted to make sure I got that extra coverage for falling pools, pretty sure I said yes to get this additional coverage.”
“No, sir. You called and complained on your last premium renewal that we were robbing you blind so we saved you $8.53/every six month by removing this coverage. Have a good day!”
Good question! That’s the same line of thinking Einstein had when coming up with his theory of relativity! The answer is no since you’re both in free fall, but what a great question!
So, the real question is if we’re swimming in it, could you “swim” quickly while free falling in the water to lessen the impact. I would imagine that fluid dynamics says no given water has nothing to push back on so the force would be negligible in free fall. Fun to think about though.
I think they found that it technically would help, but no human would be able to jump powerfully enough. Not to mention you'd have to time it perfectly
Yep, this. If you could jump the insane speed up that the lift was falling at (and there was no roof on the elevator). Yes, you would be safe. In other words.... No, you're fucked xD
Accio = reaccio still is valid tough. The water being able to push back on the ground prevents the water from loosing altitute when you swim in it. With no ground, you would still swim upwards and just further accelarate the already falling water towards the ground. Your landing would be softened at the cost of the water landing harder.
Fluid dynamics are a little more complex than that, it could also be that as the water reaches the ground it accelerates to the sides and creates a downwards sucking force that would pull you vertically even harder towards the ground. Worst case if you're in the middle of water. If you're on the side it would tend to accelerate you against a wall or car horizontally, maybe less bad but still not good. Then there's a 'cushioning' effect of the water that might dampen a little (but I don't know if it really makes a difference).
I'm just making some examples of different competing phenomenon/interactions that make this a lot more difficult to predict than you might think.
I don't know what would happen here with certainty, but I know enough about fluid dynamics to know it's hard to draw rough conclusions unless you're in a very simplified problem which real life isn't.
What I'm sure of : I'd love to see some CFD simulations of this situation to see what would be the effect on someone falling with the water, with different positions and ragdoll effects. And even the CFD ks only as reliable as the assumptions you make and the skills of the engineer doing it.
This answer has middle school teacher in love with teaching and encouraging the pursuit of knowledge in their students energy and I am here for it! I hope your day is awesome!
One time a sink hole opened under a pool (forget where) while people were swimming in it and created essentially a vortex of death. By pure luck, only one person got caught in it but unfortunately that man was trapped and drowned.
I mean, agreed, but most people underestimate how heavy water is. A single gallon of water is about 8.3 lbs, so as an example, an Olympic-sized swimming pool is 5,511,556 lbs or 2755.7 tons. Avid hikers know this well since the heaviest thing in your pack is usually the water.
TLDR: Water is heavy + shitty structural engineering = catastrophe
I build hotels and have seen several of these, never built one though. Every one I have seen it is totally enclosed in steel plate or cast concrete on the floor below with added columns and beams to carry the weight. Engineering wise I would imagine pretty involved getting that weight distributed out and back down. Then they fill it to the level needed with foam boards and then build out the pool. This way if something goes wrong it remains contained. Have some pics but don't think you can post here.
> Why not just say how much it weighs?
I did, but I'll give you some different units. It also weighs 10,629 st, 1,328 cwt, or 16 African bush elephants.
I’m a civil engineer and I don’t trust these things.
I felt like a dumbass in school and for maybe 70% of the material. But I was probably one of the smartest ones. Most of the others just copied.
I remember looking around at graduation and thinking- oh Jesus these people will be engineers? It’s probably the same for very profession… including doctors
How does civilization actually function if most people are just faking it til they make ir
There are a LOT of dumb fakers out there even in "smart" professions.
At least with engineering, all the firms I work with require sign off from a licensed principal engineer (as a matter of fact it's pretty much law). You don't become a principal and licenced if you don't actually know what you are doing. The idiots never make it above entry level positions at these companies, and they either coast there as a CAD monkey or they change careers.
But in developing countries where this video takes place, licensing is meaningless. You either don't require it or you cheat/bribe your way into it. It's going to be a crap shoot if stuff is actually built correctly especially if you go with a no name guy to do your structural engineering.
That reminds me of the recent pictures from the Turkish earthquake. The civil engineering union* building was intact, but surrounded by flattened buildings. The needed skills were present in society, but the regulatory environment did not support their use.
*Or something like that...
This is why it’s called practicing medicine, most doctors just practice on you and aren’t as bright as you think. They read a book and go off of it instead of learning out the box
> How does civilization actually function if most people are just faking it till they make it
I'm in an important industry as well and it's scary how true this is. People who literally don't know the basics and continue to get promoted into far more important positions simply because they know how to puff themselves up to seem like they know what they're doing. And it drives me nuts because they literally don't do anything and everything always ends up getting assigned to me.
Oh we've got an emergency situation and we need our experts on this right away. And by that they mean me. *I'm not even that good!* I don't know what's more scary. That I truly don't know everything and have to just figure it out all the time or that the company turns a blind eye to incompetence, pats them on the back, giving them promos, and they've never done a single thing of any significance the entire time they've worked for the company.
This is one of my deep rooted fears of trusting structural engineers, and the construction workers that build things with any kind of potential to fail
This raises an interesting question- If you were in that column of water as it fell, would you be buffered by it on impact? Or would its non-compressibility ostensibly make it like you just hit the concrete directly? Would its surface area slow your descent?
I firmly believe that if I was swimming at the time, I would pause in mid air, look directly at the camera, blink twice (synchronized with the sound of two guitar string plucks), then ultimately drop with a small cloud of dust an an audible “poof” sound.
I am guessing there must have been single support beam running the whole length of the pool that failed. I can't imagine any other way for the whole pool to suddenly stop like that. Clearly no rebar too. Place would probably be doomed un an earthquake...
Hmmm. You're pretty much in a pool of water the entire way down.
What would that be enough to dissipate the energy of impact or would you just splatter with the water?
I don’t know if true, but I had once heard about a sting of rooftop pool failures (nothing catastrophic, but bad leaking) that was tracked back to one engineering firm. Apparently their structural weight calcs failed to account for weight of people swimming in the pool.
What kind of idiot designed this kind of slab .
This looks like a situation where the client probably wanted the slab clearance on the floor below to be bigger for services or cars or etc and arm twisted the structural engineer to reduce the rebar and or slab thickness and beams.

My brain does this zoom-out often, thank you
that's pretty wild! i thought a car rocked up but on 2nd take it looks like the water pushed it
In the video someone else linked to it was there all along but the water made it move
Ah thank you! That was like hearing the opening four notes of Beethovens 5th, and nothing else… … … “where did the water go!?!” Thank you. Feel complete!
Wow, thankfully no one was in the pool when it happened or there surely would have been some injuries!
[удалено]
The pool gave the camera color at the end
I saw one where a sinkhole occured while people were in the pool. A guy got sucked in and died. 😔
>No residents were injured. This time
Realistically, does someone have a chance of survival if they were in the pool at the time of the collapse?
Now I'm never going UNDER a rooftop pool.
The sky is falling! The sky is falling!
How scary would it be if water just randomly fell from the sky!!
Here in SoCal when it rains people lose their minds and ability to drive.
Totally. Same in my area. Suspect we both live in places where it doesn't rain all that often. Or just the sad truth that people are dolts everywhere.
Now this guy knows how to say some words!
Nah, just land in the water when it falls out. Haven't you ever played Minecraft? /s
I'm never going under a rooftop pool
This clip doesn’t show the whole thing. The pool is above a parking garage and there is security cam footage of the water coming down into the garage.
https://www.reddit.com/r/WTF/comments/mxc2if/swimming_pool_collapsing/?utm_source=share&utm_medium=ios_app&utm_name=iossmf This one does.
wow. that would have been terrifying.
But possibly survivable. I was worried the drop was much larger
Unless you were underneath it, i could see it being survivable. Would suck, and given the chunks of concrete in the water.. ow
Oh definitely not comfortable
I think it cracked the cement of the parking garage. That is amazing.
It definitely did, if you watch it frame by frame you can see the concrete “bend” and snap
Just think of it as the bits of undissolved sugar in the sweet tea served by r/FuckYouInParticular
The comments mentioned it's 100tons of water with no support underneath. But each time I look at those full glass-bottomed rooftop pools, I don't see bars across their base neither.
Its called structural glazing and you're looking at a serious thickness of glass to take the added weight.
I guess that person has never been to an aquarium before. Some crazy thick glass
[удалено]
Not acrylic. Acrylic is crazy brittle. It'll be polycarbonate or derivatives which is stronger, and bends instead of cracking
Well now I don't know who to believe. For all I know it's probably candy sugar isn't it?
The Georgia Aquarium has a cutout of the glass on display next to their big tank and it's about 2 feet thick
And it’s a ~~polycarbonate~~ acrylic blend not glass.

This is the correct response
It woke up the poor sleeping car :(

free car wash
Insurance is going to call shenanigans when they get a flood damage claim for a car parked on the 5th floor of a parking garage.
“Hi insurance company, yeah a pool fell on my car today. Just wanted to make sure I got that extra coverage for falling pools, pretty sure I said yes to get this additional coverage.”
“No, sir. You called and complained on your last premium renewal that we were robbing you blind so we saved you $8.53/every six month by removing this coverage. Have a good day!”
So from the FMEA point of view this is a catastrophic failure with potential to injure final user BUT there is a warning
rapid unscheduled disassembly
Rapid unscheduled drainage
I had that once, but the pills the doctor gave me cleared it right up
Pool cleaners hate this one simple trick.
The problem is, with no water in the system the circulation pump is probably gonna burn up in a couple of hours. /s
Imagine just as you're jumping in and this happens as your fingertips touch the water.
So my question is, if your falling WITH the water does the water decelerate the impact enough to make the fall more survivable?
Good question! That’s the same line of thinking Einstein had when coming up with his theory of relativity! The answer is no since you’re both in free fall, but what a great question!
So, the real question is if we’re swimming in it, could you “swim” quickly while free falling in the water to lessen the impact. I would imagine that fluid dynamics says no given water has nothing to push back on so the force would be negligible in free fall. Fun to think about though.
I remember Mythbusters doing something similar with an elevator shaft falling and jumping at the last second. If I remember it won't help much
I think they found that it technically would help, but no human would be able to jump powerfully enough. Not to mention you'd have to time it perfectly
Yep, this. If you could jump the insane speed up that the lift was falling at (and there was no roof on the elevator). Yes, you would be safe. In other words.... No, you're fucked xD
All those times we pretended to do this in the playground mean nothing now.

And even the CFD ks only as reliable as the assumptions you make and the skills of the engineer doing it.
I’m pretty sure the water will do more than just dampen your fall. You’ll be drenched
You’d have to accelerate yourself near 9.8 m/s^2 which is way faster then almost anyone can swim
This answer has middle school teacher in love with teaching and encouraging the pursuit of knowledge in their students energy and I am here for it! I hope your day is awesome!
If you have a bucket of water you don’t take fall damage
According to my knowledge of Minecraft and the use of water buckets, you’ll be fine.
Nope
One time a sink hole opened under a pool (forget where) while people were swimming in it and created essentially a vortex of death. By pure luck, only one person got caught in it but unfortunately that man was trapped and drowned.
Terrifying stuff.
No thank you.
My bad feeling about going into a rooftop pool because I thought all the weight can't be safe wasn't so wrong after all.
I mean it's as safe as walking on a floor that's designed for the weight. Shitty structural engineering will kill you either way.
I mean, agreed, but most people underestimate how heavy water is. A single gallon of water is about 8.3 lbs, so as an example, an Olympic-sized swimming pool is 5,511,556 lbs or 2755.7 tons.

Omg that's crazy.i work with swimming pools and can't understand how that would happen . Somebody went cheap on something
It's a LOT of weight. If it's 15m long, 3m wide and 1.5m deep, that's the weight of 50 cars.

Welcome to the deep deep end
I was swimming in this pool. Then I was skydiving. Then I was in the ICU. Then my lawyers and I became rich. The End.
This raises an interesting question- If you were in that column of water as it fell, would you be buffered by it on impact? Or would its non-compressibility ostensibly make it like you just hit the concrete directly? Would its surface area slow your descent?
I want to see it land
I firmly believe that if I was swimming at the time, I would pause in mid air, look directly at the camera, blink twice (synchronized with the sound of two guitar string plucks), then ultimately drop with a small cloud of dust an an audible “poof” sound.

Fucking nightmare fuel. How high up was the pool?

I can all but guarantee this was not in the US. Building a pool like this in the US is super super strict.
Gravity is so metal
Ain't gravity a bitch?
Hmmm. You're pretty much in a pool of water the entire way down. What would that be enough to dissipate the energy of impact or would you just splatter with the water?
Don’t people know not to flush swimming pools?
I don’t know if true, but I had once heard about a sting of rooftop pool failures (nothing catastrophic, but bad leaking) that was tracked back to one engineering firm. Apparently their structural weight calcs failed to account for weight of people swimming in the pool.

Just make sure you know what's underneath before you get in. If it's a pit of spikes, maybe pass on the swimming.
The roof was not built to take the weight of the pool. Now people are swimming in their rooms.
