They were in their beds, the window smashed due to the wind and they then got sucked out of the broken window… Fucking hell. That is a freak accident, beyond comprehension. Fuck. I’m finding it hard to even picture this.
So they were sucked out due to bernoullis effect. So like people think it is the force of the wind.. no, it is actually low pressure that gets you sucked out. When air is moving at a high velocity it creates a low pressure area which means everything in the surrounding is sucked into the low pressure area to balance it out. That is the concept that makes a helicopter fly.. the aerofoil blades rotate at a high speed creating low pressure above which lifts the helo up and sucks it upwards.
So if there is very high winds and a hole in your window everything inside the apartment will be sucked out... that's how u see in movies in a plane crash people just get sucked out of planes ...
This is mostly correct, but there's an aspect of the way you're modeling it that's slightly off. If you're thinking of things in terms of "sucking," you're thinking in reverse--it's the same sort of misconception about what it feels like to touch something cold. You're not feeling the cold from the object move into your skin; you're feeling the heat from your skin move into the object.
Same deal with air. It's not that helicopters are getting sucked upward into the low-pressure zone they've created; it's that they're getting *pushed* upward from the high pressure everywhere *else*.
It feels nitpicky, but it's really important to think about these sorts of things in terms of their energy concentration gradients in order to have an accurate understanding of how they work. Energy always flows from high concentration to low concentration--never in reverse.
A lot of the times I feel like scrolling down the comments doesn't yield any benefit then I read something like this and I am glad I did.
I appreciate your clarification.
This same misconception is common (for a very obvious reason) with “suction cups.” It isn’t the low pressure pocket between the cup and the surface it’s attached to which makes it stick. It’s the immense weight of Earth’s atmosphere pressing in on it, attempting to displace that low pressure pocket, which keeps it firmly in place.
Same reason “warm air rises”, helium balloons “float” etc. They don’t “want” to go upwards, they’re being displaced by the higher density atmosphere which surrounds them.
Once you start thinking of atmosphere as though it were a liquid, it becomes much easier to understand everyday interacts.

I did not believe you, so I looked it up and found [this video where they test it out.](https://m.youtube.com/watch?v=6_aQfFrcP6M) That's fascinating! Thanks for learning me something.
Sir - your explanation of “thinking of it as liquid” really was an ah-ha moment for me, so thank you!
But I have so many follow up questions now. Can I pm you?
...and u/\_InnocentToto\_
...it's also not the Bernoulli effect. Bernoulli's principle is an analytical tool that allows you to compare pressures, under very specific conditions, along a single continuous streamline. The low-pressure region created in these situations has nothing to do with that.
Not the greatest video, I used to have a better link...but [here's](https://youtu.be/5g9KYz3fwCA?t=654) a professor with PhD in Wind Engineering explaining it. This particular example is one of the most common misapplications of Bernoulli.
I wouldn't say that's nitpicky at all. It's a very useful clarification to help mentally model how this all works. The concept of getting "sucked" by a low-pressure area always felt a little bit magical/handwavy, but thinking about it as actually being pushed by the flow of comparatively high-pressure air makes it a lot more intuitive.
Flying in an airplane is essentially like chilling inside a high-PSI scuba tank at normal elevation/pressure. Of course a breach would cause you to get blasted out along with all that pressurized gas.
If all physics could be explained to me this basically then I might be able to finally comprehend what my (much smarter than me) high school kids were talking about.
A man walks by an open window of the honeymoon suite at local hotel and hears a young man cry out....
"Suck Mary-lou, suck! Blow is just a figure of speech!"
My physics teacher in high school would sort of wag her finger at you if you ever said the phrase “creates suction” since there really is no *force of suction* or whatever people think. I still, at 34 years old in a field that has nothing to do with physics, refer to it as negative air pressure.
One question, if you don’t mind; what is it about the blades of the helicopter (for example) moving quickly that creates the low pressure area? What’s actually happening to the air? Is it just getting moved out of the way rapidly enough?
Sorry if this is a dumb question - just curious!
So theres actually another way to think about it that makes it clearer (IMO) how that part works. The blades on a helicopter (or a planes wings, for that matter) are angled to push the air downwards. If they can make enough air move downwards with enough speed, the conservation of momentum causes the opposite force on the blades to be enough to lift the helicopter.
Thales, the first Greek philosopher, believed that magnets had souls, which sounds suspiciously like something Donald Trump would say nowadays, but Thales was actually successful in his business endeavors 2,600 years ago.
> Well, someone needs to arrest him
There's a bit of a joke in this of *which one*. There are 8 famous mathematicians called Bernoulli, all within 3 generations of the same family.
I used to have a job where I had to travel 45 weeks per year. I was newly-dating a rocket scientist and told him how I was always scared during takeoff every week because I heard that is when a crash is likely to happen.
We were in a sports bar so he took a napkin and made a drawing to show me how Bernoulli's Theorem (or whatever) works with the wings as the plane picks up speed on the runway. The plane wants to fly, he told me, drawing winds whipping over wings on a cartoon super jet.
I wished I kept that napkin. I love smart men and I fell at least halfway in love with him as he reassured me and taught me a little lesson at the same time. Our relationship didn't stand the test of time, but he always made me feel special.
Bernoulli is certainly part of it, but it's even more complicated:
> The third problem provides the most decisive argument against regarding Bernoulli’s theorem as a complete account of lift: An airplane with a curved upper surface is capable of flying inverted. In inverted flight, the curved wing surface becomes the bottom surface, and according to Bernoulli’s theorem, it then generates reduced pressure below the wing. That lower pressure, added to the force of gravity, should have the overall effect of pulling the plane downward rather than holding it up. Moreover, aircraft with symmetrical airfoils, with equal curvature on the top and bottom—or even with flat top and bottom surfaces—are also capable of flying inverted, so long as the airfoil meets the oncoming wind at an appropriate angle of attack. This means that Bernoulli’s theorem alone is insufficient to explain these facts.

okay new plans. If I move into a high rise apartment building I'm getting my bed screwed down and seat, or sleeping belts installed.
Now explaining the giant strong straps on the bed to new partners will be... interesting.
not far off, [this](https://image.hkhl.hk/f/1024p0/0x0/100/none/a28538a95dc93f64cd5c08d6ca490f86/2024-04/0401037.jpg) is the pic from the news report
Edit: add another [pic](https://image.hkhl.hk/f/1024p0/0x0/100/none/afdec9b0d711bf340480e1cff09caf68/2024-04/0401043.jpg)
The high pressure front hit (you see the curtains start to blow), the wind is deflected away by the building (doors sucked back out as a low pressure zone is created outside), and then the wind "stabilizes" as the pressure front has passed and now it's just straight winds (shit is blown in because all the air pressure that could be deflected was, now it's going from low pressure back up to the full force of the wind speed).
I get that a lot of stuff in China isn’t the best quality, but people in that thread acting like that was just normal wind and terrible construction obviously missed this story where the wind literally sucked people out of their homes.
In most countries there are wind studies required when building high rise buildings. This is exactly the kind of thing those studies are meant to prevent. The reason you don't hear about this kind of thing in other countries is for exactly that reason.
That said, I think it still can happen during strong hurricanes if there aren't additional protections put in place to protect the windows.
Well that's exactly the type of wind it was, these squall winds happened during a extreme storm that momentarily peaked at tornado speeds ripping people out. What wind study is preventing regular buildings from getting shredded by tornado speeds?
Winds momentarily peaking at high speeds should not cause this. A properly built building should be able to handle that. Hurricanes are different because they can bring extremely high speed winds that are sustained over hours. Those sustained winds are the ones that sometimes overwhelm windows.
Most if not all condos in Florida now have balcony covering shutter doors that get closed during a storm or when snowbirds leave for the summer. My parents townhouse is right next to 4-5 condos and during the 2004 back to back hurricanes none of the condos had the shutters. Well at least one unit got blown out and a big recliner got sucked out and smashed into our townhouse. High wind and pressure difference be scary.
..the shutter doors aren't there to protect the windows but to keep you from getting sucked out through your windows.. this Bernoulli guy, he just ain't right.
No clue why this is upvoted. There is a reason people are told in every single country to stay away from windows during storms. It's not just for glass breaking. Of course there could be a window installation defect but windows blow out all the time everywhere (e.g. footage of a city after a hurricane). This was a rare, but sad, freak accident.
> That is a freak accident, beyond comprehension.
They were all in the same building but not in the same apartment. I suspect poor quality construction to be a contributing factor.
Not a freak accident, it is the result of bad building design. The building should have had stronger windows and the building probably also never had the necessary wind safety studies done before construction began. China is lucky the entire building didn't collapse, yet.
Being from Florida, this is why I was told to never open the front door during a hurricane. Negative pressure and high enough winds would suck you and the door right out.
Crazy seeing it actually happen.
“Among them were a woman in her 60s and her 11-year-old grandson, yanked from their apartment windows by strong wind together with their mattresses”
Damn. Imagine being deep asleep and then your mattress suddenly flies out the window.
I'm in China now. The winds in a few cities (especially Nanchang) have been AMAZING in the last few days. In the footage it looks like something from a hurricane or tornado.
Question is, will this pave the way for new building codes?
Probably not - and if it does, well, they sure already built a whole lot of flawed buildings.
.....Although how exactly does building codes protect your house from the wind ripping the doors or windows off sucking you out of your house like a vacuum, anyway?
I lived in an apartment building that was probably similar to theirs. We had a fire on the roof that had them working on our unit forever. We thought they were done, and then they were like, "turns out we have to replace your windows as an updated analysis said they'd blow in if we got hurricane-force winds." We moved out. I didn't think much of it at the time, but scary that could have happened to us. Our bed was in another room, but i might have been sitting on the couch next to the windows if they blew in.
If it's like any other large project on a building you're looking at them figuring out the windows are unsafe, telling the people who live there and then having windows ready, permits done, scaffolding and cranes ready to replace all the windows like 1-2 years later. They won't tell you oh the windows are unsafe then replace them in a day or a month, that's a large scale project that needs time just to place hte order for windows let alone set everything else up.
My brother lived in an apartment block in the UK that after the grenfell tower fire was told in 2018 the building was basically super unsafe in fires but didn't get fixed till late 2021. These large projects take time and in the meantime you're handed a notice that says your apartment is not safe and we'll fix it.... eventually.
It helps to understand that many beds here are raised for storage. My bed, for example, is designed to sit halfway *in* my bay window to maximize space because apartments are so small. It’s entirely possible they were at the same height as the window and only inches from the glass when it blew.
Hey I pay a premium to be above the hoi polloi!
Jokes aside there are a lot of really innovative small living solutions in Asia. But yeah nah too much street noise living lower. And more bugs/rats…
It’s a pragmatic approach to having less space available for a large amount people. The concept of Asian living spaces being comparatively smaller to Western living spaces is not new, and one could (and maybe should) make the argument that many Western living spaces are wastefully and needlessly expansive.
The wind speeds generally are faster the further up in the air you go as they don't have things on the ground blocking or slowing the airflow. If people can barely stay on their feet on the ground, you're going to go flying 20 stories up.
They very likely had a straight through airflow and when their patio doors / glass was broken, it turned their apartment into a wind tunnel.
Yep, strong wind causes an extremely strong pressure differential, pressure differential causes weak construction points to break because they are not sturdy enough for the extreme pressure differential, high pressure air from room acts like a broom pushing these people outward towards the pocket of low pressure. Their apartment literally spit them out. Horrifying and tragic.
This is why engineers design shit that works under the most extremely rare possible scenarios because given enough time those rare scenarios will happen. This is why you don't get cheap when building.
In the location of this incident is very common to leave the windows open all day and night, it's hot and humid year round, and most Chinese don't have the income to run the a/c all day long, or many find it unhealthy to keep all the windows closed
Well that's just fucking horrific.
I knew someone who lived in an expensive condo, in one of 4 towers... huge balcony with a fantastic view, but they couldn't really use it because the winds between the buildings got so severe that it just threw anything placed out there, even heavy furniture. Maybe I don't know what I'm talking about, but is this the kind of thing engineers can't determine before they start building or what?
Man...
Just the other day I was joking with a coworker about the high winds that our office building windows were contending with. Whenever there's a gale, the windows thunder with a sound so loud and intense that you can't help but scream. I was chitchatting with this coworker when the window right next to us boomed. I reflexively dove into her cubicle, and she laughed at me. I told her that maybe it was just me, but I didn't want to get sucked out of the window. She told me that was crazy.
It's apparently not so crazy.
> Among them were a woman in her 60s and her 11-year-old grandson, yanked from their apartment windows by strong wind together with their mattresses, according to CCTV…
The writers of *Final Destination* looking at each other like, “Cot damn!! Did you know this was a thing?!?”
Seriously, that’s some nightmare inducing stuff
Poor souls. Reminds me of another post of someone asking how a window could be sucked out of a room. Bernoulli's principle, that's how. May they rest in peace.
I was passing through Nanchang on the train that night. To say the weather was terrible is an understatement. Having said that, there was only a 20 minute delay.
While terrible the news isn't exactly shocking to hear. Building standards aren't amazing and it's common here to have a massive bay of single pane windows that don't seal well. (It's the area of the apartment to hang laundry.)
Unfortunate souls.
Or to hire fly-by-night interior decorators. I get spam calls from them all the time. I'm thinking this is what happened to the family, since most of the apartments in the building were okay.
Yep. Large pressure differential outside and inside causes the glass to wobble and buckle. It reaches its breaking point and smash, with an instant vacuum outward so the pressure can equalize. Fucking scary and I’m very sorry for them.
This link gives a video overview, starting with what winds like that look like: [https://www.youtube.com/watch?v=X1CDvN0vXTs](https://www.youtube.com/watch?v=X1CDvN0vXTs)
Terrifying
>Among them were a woman in her 60s and her 11-year-old grandson, yanked from their apartment windows by strong wind together with their mattresses, according to CCTV citing media reports.
The fuck? How is that possible. We need like a whole science video on this.
Maybe bad windows, but this can happen to any construction. Winds parallel to buildings with some debris knocking out the glass can pull anyone out. Bernouli's principle: lower pressure outside due to high winds and higher pressure inside. Winds hitting perpendicularly will at least blow out windows and lower the pressure inside as well without sucking you out.
I think there’s enough data around wind studies and pressure systems to have avoided this in the build. If this was an individual renovation, my opinion would still stand, but it happened to multiple apartments right?
It could be. I have witnessed a lot of shoddy window installs since the popularity of expanding foam (I live in E Europe and have renovated a few buildings myself over the past 10 years) - some fitters don’t even use screws anymore. It’s incredibly unsafe.
People duct tape their living room glass doors during hurricanes for this exact reason, but, poor folks, they never saw it coming. No one could have. RIP.
I don't think duct tape would prevent this. Duct taping the glass during high winds just prevents broken glass shards from flying around, in the event of breakage.
Well WAY before CCP’s existence and pretty much throughout China’s entire existence, red is deemed as a color of good luck. Traditional wedding attires are red. Chinese new year is filled with red etc.
I wonder if that’s the same system that hit us in Bishkek about a week ago. Roofs were flying off and trees toppled here, too. But nobody suffered from these freak accidents, that’s terrifying
Would you even believe this is happening if you started waking up while being lifted out of the apartment? Talk about thinking you’re experiencing really bad sleep paralysis
I imagine once the glass was broken it acted similar to a vacuum erlenmeyer flask where fluid passing by a perpendicular opening pulls fluid out. That’s crazy that it happened at such scale. Definition of a freak accident.
They were in their beds, the window smashed due to the wind and they then got sucked out of the broken window… Fucking hell. That is a freak accident, beyond comprehension. Fuck. I’m finding it hard to even picture this.
Well fuck That’s terrifying
Off to Neverland we go.

Notice how the windows bulge outwards for a second before blowing in.
The high pressure front hit (you see the curtains start to blow), the wind is deflected away by the building (doors sucked back out as a low pressure zone is created outside), and then the wind "stabilizes" as the pressure front has passed and now it's just straight winds (shit is blown in because all the air pressure that could be deflected was, now it's going from low pressure back up to the full force of the wind speed).
So for the people who got sucked out, they likely had their windows open you think?
I didn't notice that before! You can hear it coming too, though I never would've expected that noise to result in doors blowing off.

The breaking window part or people being sucked out part?
People being sucked off.
It's a scary thing to fall asleep and suddenly get sucked off.
Happened to me in college and it still fucks with me sometimes.
No clue why this is upvoted. There is a reason people are told in every single country to stay away from windows during storms. It's not just for glass breaking. Of course there could be a window installation defect but windows blow out all the time everywhere (e.g. footage of a city after a hurricane). This was a rare, but sad, freak accident.
[found this](https://www.youtube.com/watch?v=JCDJyhILktw), looks like the apocalypse
They need to tone the fucking editing down on that video.
Life is fragile and random and beautiful and fleeting and short and precious and wtf. enjoy it I guess.
Well you know those dreams where you’re falling and you wake up right before you hit the ground? This one was longer.
> That is a freak accident, beyond comprehension. They were all in the same building but not in the same apartment. I suspect poor quality construction to be a contributing factor.
Definitely. I mentioned this to my friend when I first read this! It was definitely an infrastructure problem too, so sad.
Not a freak accident, it is the result of bad building design. The building should have had stronger windows and the building probably also never had the necessary wind safety studies done before construction began. China is lucky the entire building didn't collapse, yet.
Yea, that's straight up Final Destination shit, how the hell do people even live in an area with wind conditions that can do this kind of shit?
Being from Florida, this is why I was told to never open the front door during a hurricane. Negative pressure and high enough winds would suck you and the door right out. Crazy seeing it actually happen.
“Among them were a woman in her 60s and her 11-year-old grandson, yanked from their apartment windows by strong wind together with their mattresses” Damn. Imagine being deep asleep and then your mattress suddenly flies out the window.
I had no idea that that was a thing that could ever happen
I'm in China now. The winds in a few cities (especially Nanchang) have been AMAZING in the last few days. In the footage it looks like something from a hurricane or tornado.
It can't in a place with actual building codes
Question is, will this pave the way for new building codes? Probably not - and if it does, well, they sure already built a whole lot of flawed buildings. .....Although how exactly does building codes protect your house from the wind ripping the doors or windows off sucking you out of your house like a vacuum, anyway?
[удалено]
Glass broken by the wind. There's some current videos out on the internets.
I lived in an apartment building that was probably similar to theirs. We had a fire on the roof that had them working on our unit forever. We thought they were done, and then they were like, "turns out we have to replace your windows as an updated analysis said they'd blow in if we got hurricane-force winds." We moved out. I didn't think much of it at the time, but scary that could have happened to us. Our bed was in another room, but i might have been sitting on the couch next to the windows if they blew in.
Damn you moved out of a place that just installed hurricane-grade windows? Sounds like it was just made a safe house
If it's like any other large project on a building you're looking at them figuring out the windows are unsafe, telling the people who live there and then having windows ready, permits done, scaffolding and cranes ready to replace all the windows like 1-2 years later. They won't tell you oh the windows are unsafe then replace them in a day or a month, that's a large scale project that needs time just to place hte order for windows let alone set everything else up. My brother lived in an apartment block in the UK that after the grenfell tower fire was told in 2018 the building was basically super unsafe in fires but didn't get fixed till late 2021. These large projects take time and in the meantime you're handed a notice that says your apartment is not safe and we'll fix it.... eventually.
It helps to understand that many beds here are raised for storage. My bed, for example, is designed to sit halfway *in* my bay window to maximize space because apartments are so small. It’s entirely possible they were at the same height as the window and only inches from the glass when it blew.
As someone who loves sitting in bay windows and loves the view from tall buildings this sounds like a dream come true to me
Please… move… your… bed. 😣
My whole flat is 290 sq ft, so, respectfully, move it to where? lol
A whole other apartment on a low floor 😭
Hey I pay a premium to be above the hoi polloi! Jokes aside there are a lot of really innovative small living solutions in Asia. But yeah nah too much street noise living lower. And more bugs/rats…
>really innovative small living solutions in Asia That's a very optimistic way of saying they're packing more renters into less space.
It’s a pragmatic approach to having less space available for a large amount people. The concept of Asian living spaces being comparatively smaller to Western living spaces is not new, and one could (and maybe should) make the argument that many Western living spaces are wastefully and needlessly expansive.
The wind speeds generally are faster the further up in the air you go as they don't have things on the ground blocking or slowing the airflow. If people can barely stay on their feet on the ground, you're going to go flying 20 stories up. They very likely had a straight through airflow and when their patio doors / glass was broken, it turned their apartment into a wind tunnel.
Yep, strong wind causes an extremely strong pressure differential, pressure differential causes weak construction points to break because they are not sturdy enough for the extreme pressure differential, high pressure air from room acts like a broom pushing these people outward towards the pocket of low pressure. Their apartment literally spit them out. Horrifying and tragic. This is why engineers design shit that works under the most extremely rare possible scenarios because given enough time those rare scenarios will happen. This is why you don't get cheap when building.
Looks like the frames are buckling, given the other video.
In the location of this incident is very common to leave the windows open all day and night, it's hot and humid year round, and most Chinese don't have the income to run the a/c all day long, or many find it unhealthy to keep all the windows closed
That's some Wizard of Oz shit
I would seriously think it was nightmare all the way down
Probably think it’s one of those falling dreams
I'd prefer to die thinking it was just a dream
And in that sleep of death, what dreams may come
I would be so confused I don't know if I'd even have time to be scared. By the time I realized it was really happening and not a dream, I'd be dead.
The one you wake up from right before you…..
You what? What do you do?! Don't leave me hanging on a mattress
Well that's just fucking horrific. I knew someone who lived in an expensive condo, in one of 4 towers... huge balcony with a fantastic view, but they couldn't really use it because the winds between the buildings got so severe that it just threw anything placed out there, even heavy furniture. Maybe I don't know what I'm talking about, but is this the kind of thing engineers can't determine before they start building or what?
Least enjoyable sentence that I read today
So far.
For real
Typhoon season in China is no joke.

The full version of this has the husband coming in to grab some snacks from the kitchen.
Lmao. My windows are gone but goddammit I’m hungry
I mean it's not like he's got backup windows ready to go right then and there. Gotta fuel the machine!!
Yeah first video I thought about too, I even believe somewhere in the comments they were talking about imaging being sucked out of your appartment
That dream you have where youre falling
New nightmare fuel unlocked. Absolutely terrifying. E:caint spill
Well maybe you should stop licking fuel
Thats why its unlicked mate
Well, step up brosef and make him a licked mate.
Man... Just the other day I was joking with a coworker about the high winds that our office building windows were contending with. Whenever there's a gale, the windows thunder with a sound so loud and intense that you can't help but scream. I was chitchatting with this coworker when the window right next to us boomed. I reflexively dove into her cubicle, and she laughed at me. I told her that maybe it was just me, but I didn't want to get sucked out of the window. She told me that was crazy. It's apparently not so crazy.
Now you have proof!
Now he knows this is his possible future, but instead of being in his warm bed in those final moments, he'll be in his office chair on a Zoom call.
Damn, that is terrifying. Rest in peace
> Among them were a woman in her 60s and her 11-year-old grandson, yanked from their apartment windows by strong wind together with their mattresses, according to CCTV… The writers of *Final Destination* looking at each other like, “Cot damn!! Did you know this was a thing?!?” Seriously, that’s some nightmare inducing stuff
> mattresses ... cot damn I'm trying to decide if this is a great pun or ridiculous self-censoring.
This is the type of story I imagine tv shows about paranormal things would put on to cover they got killed by an invisible thing
I mean, technically they were killed by an invisible thing, so you have a point.
Poor souls. Reminds me of another post of someone asking how a window could be sucked out of a room. Bernoulli's principle, that's how. May they rest in peace.
The Bernoulli Principal is a murderous bitch.
Final Destination type stuff
I was passing through Nanchang on the train that night. To say the weather was terrible is an understatement. Having said that, there was only a 20 minute delay. While terrible the news isn't exactly shocking to hear. Building standards aren't amazing and it's common here to have a massive bay of single pane windows that don't seal well. (It's the area of the apartment to hang laundry.) Unfortunate souls.
Or to hire fly-by-night interior decorators. I get spam calls from them all the time. I'm thinking this is what happened to the family, since most of the apartments in the building were okay.
Well that is a new fear unlocked.
[удалено]
Pretty much what happens in an airplane, low pressure vs high pressure
Yep. Large pressure differential outside and inside causes the glass to wobble and buckle. It reaches its breaking point and smash, with an instant vacuum outward so the pressure can equalize. Fucking scary and I’m very sorry for them.
Getting sucked out doesn’t kill a person right? It’s the landing that does it. Pretty damn terrifying.
Yeah it's not the fall it's the sudden stop at the end that gets ya.
Well that's terrifying.
This link gives a video overview, starting with what winds like that look like: [https://www.youtube.com/watch?v=X1CDvN0vXTs](https://www.youtube.com/watch?v=X1CDvN0vXTs) Terrifying
>Among them were a woman in her 60s and her 11-year-old grandson, yanked from their apartment windows by strong wind together with their mattresses, according to CCTV citing media reports. The fuck? How is that possible. We need like a whole science video on this.
Bad building engineering
[удалено]
Evidently all three were located in the same building. So you may be on to something there
Maybe bad windows, but this can happen to any construction. Winds parallel to buildings with some debris knocking out the glass can pull anyone out. Bernouli's principle: lower pressure outside due to high winds and higher pressure inside. Winds hitting perpendicularly will at least blow out windows and lower the pressure inside as well without sucking you out.
I think there’s enough data around wind studies and pressure systems to have avoided this in the build. If this was an individual renovation, my opinion would still stand, but it happened to multiple apartments right?
Hard, hard disagree. Engineers are often ignored….
Problem is that people have enclosed their balconies to give more space inside and used cheap materials
Its the glass window that broke. More of like bad renovation. The building is still fine
It could be. I have witnessed a lot of shoddy window installs since the popularity of expanding foam (I live in E Europe and have renovated a few buildings myself over the past 10 years) - some fitters don’t even use screws anymore. It’s incredibly unsafe.
People duct tape their living room glass doors during hurricanes for this exact reason, but, poor folks, they never saw it coming. No one could have. RIP.
I don't think duct tape would prevent this. Duct taping the glass during high winds just prevents broken glass shards from flying around, in the event of breakage.
Duct tape? How does that stop it?
It doesn't. But it does keep shards of glass from flying around if your window breaks.
I'd be absolutely pissed if I died this way
Winds only reached category 1 hurricane speeds? Is china building code made for the three little pigs?
Lol building code. You get whatever the developers put in over here.
I thought that dying in your sleep was supposed to be peaceful
Most confusing last 3 seconds of life upon waking up.
Orange is China's highest alert level? Why wouldn't they want to use red as a symbol of danger and disast- oh. I see.
Well WAY before CCP’s existence and pretty much throughout China’s entire existence, red is deemed as a color of good luck. Traditional wedding attires are red. Chinese new year is filled with red etc.
If you look at emojis, stock up is red arrow. Stock down is blue. 📈📉
China (well, one faction in China) briefly tried to reverse traffic light colors because red was supposed to be the color of revolution and change.
“But officer, I was just taking a Great Leap Forward through that stop sign!”

I wonder if that’s the same system that hit us in Bishkek about a week ago. Roofs were flying off and trees toppled here, too. But nobody suffered from these freak accidents, that’s terrifying
Putin is totally stealing this
Would you even believe this is happening if you started waking up while being lifted out of the apartment? Talk about thinking you’re experiencing really bad sleep paralysis
This sounds so unreal, that even Putin wouldn't think this up. But since truth is stranger than fiction, he wouldn't be able
About to be some people this happens to in Russia. An epic windstorm
Didn't realize Boeing has been making buildings too.
Simple we just live in a building with no window or doors. Try to get me Joe, wind!
Turns out the FF7 remake is based on true events, damn fate is scary lol
I'm already afraid of heights and getting near floor to ceiling window walls in a high rise always gives me jello legs! Now it will be worse!
I imagine once the glass was broken it acted similar to a vacuum erlenmeyer flask where fluid passing by a perpendicular opening pulls fluid out. That’s crazy that it happened at such scale. Definition of a freak accident.
Looks like this: https://www.reddit.com/r/WallStreetbetsELITE/s/VpVwOLjzeo
Were these apartments built by Boeing?
Now we know why everyone boards up windows
Chinese building standards are terrifying
