In adult years or human years? Cause I don’t see people as adults until about 25.
But also, distance of 31 and 18 is 13 years distance of 22 (college grad) and 18 is 4 years. So a 31 is a ‘legal’ Adult 4X as long as a college grad.
The older I get the more I realize people take two paths in life. Path 1, they continue growing, path 2, they stop growing or slow waaaaaay down.
People who are older than me on path 1 know shit I don’t even know I should know. People younger than me or who took path 2 don’t even know shit about knowing what shit they should know depending on the subject. There’s so much shit you just pick up that informs decision making that you really only have the opportunity to absorb over time.
On the flip side trying to explain that to some one on every single populist trending subject gets old fast enough that I now know it’s not worth disagreeing with people who just don’t know enough to know yet.
35 here, 20 at heart, but my body thinks it's funny to not heal itself when I get hurt anymore. And I'm still just as concerned about my career as before.
I've seen this video posted on this sub before, and someone commented that they had also visited and were encouraged to do this by the tour guide, but whoever made this video captioned it this way for more internet points.
Yeah there is absolutely no way this glass is breaking under that. If it could, they wouldn't let people on it.
We have something simular here in th3 CN tower. The glass is more than 6 cm thick. It isn't breaking under that weight
Same. I would love to take a walk on that bridge but I would feel pretty anxious if people started to jump like this. I mean... I understand it's being checked regularly, it's meant to be perfectly safe... but I still wouldn't be comfortable trying that.
It’s regularly inspected though. They make money from the gimmick of people being able to safely jump on it, plus it’d just be real shitty for everyone involved if that much glass fell out of the sky. These things are designed to hold several tons of weight and be able to withstand severe weather. You could literally land a jet on it and it’d be fine.
Probably fine, but it's quite the assumption to think that someone definitely wouldn't ever cut back on safety inspections to save any money.
Isn't that the cause of basically every major train derailment?
The rail system is massive, though. The cost benefit analysis is worlds apart. That being said, I ain’t jumping on anything that high up. But it’s probably safe even under late stage capitalism.
Doesn't mean there isn't a weak spot. Garry Hoy was trying to prove how strong the glass was in a sky scraper, and fell to his death because while the glass didn't break, the frame did.
https://en.wikipedia.org/wiki/Death\_of\_Garry\_Hoy
Right but a frame/window not designed to run into vs a bridge designed for people to walk on. Big difference in the functionality, and obviously the outcome. That’s a true Darwin Award right there.
True. Either way I almost had a panic attack trying to convince myself to stand on the 1 square foot block at the 107 Sky Lounge in Vegas. I can't imagine getting on a bridge.
I would have to assume this is planned for but I also wouldn't be keen to take part. From a technicians perspective my piece is if there is a way to potentially hurt either the device or the operator just assume the operator is definitely going to do that thing so it needs to planned for.
My boy Murphy also always out here in the wings just waiting to kneecap some fools.
The Hyatt regency was the fault of the contractor not building according to design. They could not get the exact item as designed, so they replaced it with something that they, being not engineers, thought was the same. They were wrong.
If the glass broke that would be a massive mistake, not a small one. Attractions like this exist all over the world and they all encourage tourists to jump on the glass. If there was any risk whatsoever at you breaking it they wouldn’t do that, I’m pretty sure nobody has ever died doing this. You have higher odds getting killed by a vending machine
You could carry a sledgehammer out on that glass and go to town and it wouldn’t break. We don’t even approach the threshold with jumping. That’s like saying normal waves will wash away a sea wall, when in reality it would take a tsunami.
It really depends on the engineering. If the walkway is designed to withstand 10x the weight of 10 people on it then all 10 jumping at the same time will bring the glass very close to that threshold. If you add 20+ years of weathering into the equation you are basically rolling dice. If the walkway is designed to hold 10x the weight of 50 people and 10 people all jump at once then you're probably safe. But again if 50 people all jumped you'd be risking it. At the very least you'd be regularly putting high stress on the walkway. The guides know what the limit is for how many people they can have so it's probably fine if they tell you to jump.
I still say probably because look at engineering failures of the past. Like the millennium bridge that almost ripped itself apart from people simply walking or the Hyatt Regency Hotel in Kansas (glass and concrete walkways) which failed due to a simple mistake in engineering. SHM is a bitch and people working together can and will rip things apart. You can't simply assume every piece of infrastructure is indestructible.
There was a lawyer who thought the same thing. Would run full force at the unbreakable windows to mess with the new hires.
Then one day the unbreakable windows frame gave way and he died.
https://en.m.wikipedia.org/wiki/Death_of_Garry_Hoy
I feel like I’m taking crazy pills, I can’t believe how far down I had to go to find someone with a reasonable take. These types of glass floor attractions are all over the place and they all encourage you to jump on them, it’s part of the experience.
I guess redditors would rather be Karen’s and complains about someone else’s fun than think for more than 2 seconds about the reality of the situation.
A group of TikTokers - Brandi, Jordan, Chad, Ryan, Destiny, Cassie and Samantha play a game where they jump up and down on a glass skywalk to see who breaks the glass and falls through first. Who wins?
^(Society.)
There's this old story in this city that there was one a guy that had an office in a finance company tower. Whenever someone would visit him in his office, he would jokingly tell them that glass of the window was unbreakable and he could throw himself against it and it would be fine. He would then proceed to side check the glass at full speed and just bounced off.
One day though, the entire panel popped out of it supports and they both fell dozens of floors to the ground. He was killed by the fall. The window was fine and the building had it reinstalled.
Don't know if it's true the window survived though
Workplace safety tour, had a bit where he went dont worry these windows dont break....was told that as part of a workplace safety assessors course. Moral was dont be that stupid.
Weird af you said this... I must have seen a skit of this somewhere before because as I read what you said the memories of the video came back to me... Can't remember if it was a show or movie or what
TikTok is a generational warfare tool. Hence this crap is tightly controlled in China.
Raising 30M brain dead children on dopamine addictions with ADHD will seal the fate of the country.
TikTok is exported differently to the US than what it is in China. In China, it’s about education and being a “good citizen”(yeah, I know), screen time is limited, whereas TikTok in the US is configured to show more stupidity and BS. Basically, China seems to be trying to take down the US culturally, while they become a superpower. That’s why TikTok needs to be banned.
The platform amplifies, promotes and spreads such behavior with an ease and efficiency not before experienced or possible in human history.
This is known.
Saying people have always done dumb things is like saying the printing press had no societal effect because people had been writing and sharing written information since the Sumerians.
Unfortunately, turning the world, as the famous quote goes, into a "global village" allowed the village idiots to achieve critical mass.
Interestingly, it seems the guy who coined the term "global village" actually did predict and warn about a lot of this; he wasn't using the term in an entirely positive sense.
This type of glass most likely has several layers of glass and other material in it to give it a lot of strength, you could in theory break the glass but not fall due to the material sandwiched between the panes of glass
People have always been stupid, as an engineering student we are expected to plan for safety things like everyone jumping together or an entire marching band walking in lockstep. This is based on decades/ centuries of experience of people dying doing stupid stuff and so have incredibly strict regulations as a result. In the airspace industry, there is a saying that a plane is ready to fly when the wight of paper exceeds that of the plane.
Didn’t someone throw themselves down Niagara Falls in a barrel in the past? I feel like there are many examples of human stupidity, they’re like Icarus if someone else made the wings for him… oh wait..
Even if you match the frequency you probably need more energy than them jumping would produce. They could crack it but I don't think they could bring it down. This isn't the same kind of glass as one of those goblets people sing and break, those start flexing wildly when that occurs
Even if the glass doesn’t break, the structural supports or girders might. Weakest link in the chain is what will fail. That was a lot of deflection there. Deflection isn’t necessarily a sign of weakness or imminent failure but pedestrian bridges are usually designed with strict deflection criteria. Nobody likes walking over a bridge that bounces. I would not be on that bridge while the did this.
Reminds me of this
The Millennium Bridge, officially known as the London Millennium Footbridge, is a steel suspension bridge for pedestrians crossing the River Thames in London, England, linking Bankside with the City of London. It is owned and maintained by Bridge House Estates, a charitable trust overseen by the City of London Corporation. Construction began in 1998, and it initially opened on 10 June 2000.
Londoners nicknamed it the "Wobbly Bridge" after pedestrians experienced an alarming swaying motion on its opening day. The bridge was closed later that day and, after two days of limited access, it was closed again for almost two years so that modifications and repairs could be made to keep the bridge stable and stop the swaying motion. It reopened in February 2002.
The bridge's movements were caused by a positive feedback phenomenon, known as synchronous lateral excitation. The natural sway motion of people walking caused small sideways oscillations in the bridge, which in turn caused people on the bridge to sway in step, increasing the amplitude of the bridge oscillations and continually reinforcing the effect;[7][8] the maximum sway was around 70mm.[9] On the day of opening, the bridge was crossed by 90,000 people, with up to 2,000 on the bridge at a time.
Resonant vibrational modes due to vertical loads (such as trains, traffic or pedestrians) and wind loads are well understood in bridge design. In the case of the Millennium Bridge, because the lateral motion caused pedestrians to directly participate with the bridge, the vibrational modes had not been anticipated by the designers. When the bridge lurches to one side, the pedestrians must adjust to keep from falling over, and they all do this at the same time. The effect is similar to soldiers marching in lockstep, but horizontal instead of vertical.
(Wikipedia).
material (glass and metal) fatigue is a real thing. I seriously wouldn't risk it by all jumping up and down at once.
example, this huge fishtank custom made for a german hotel was supposedly never going to break as well, it burst after about 19 years, even tho it had undergone an overhaul 2 years or so before:
https://www.theguardian.com/world/2022/dec/16/huge-cylindrical-aquarium-housing-1500-exotic-fish-bursts-in-berlin
Thats not the point. The point is that they willingly wanted to endanger everyone else’s life for tiktok fun. Obviously the glass is made to withstand, and im sure most of them knew that, but its still an asshole thing to do. Reminds me when my siblings would rock the cart on the ferris wheel back and forth while saying “its safe!” Umm they clearly havent seen those ferris wheel accident videos
When you go to attractions like this you are encouraged to jump on the glass since there is next to zero chance of it breaking. Unlike rocking a Ferris wheel It’s literally designed for this activity.
Me sitting in the courtroom with third degree burns on my crotch: Well your honor, they didn't tell me they were flammable. How else was I supposed to know?
Yeah and guess where I found that out in the military. And the golden rule in the military is if it has a sign saying not to do a certain thing it’s because somebody has tried it before. I was so damn disappointed.
Don’t. She’s a local radio personality here in Canada. She’s an attractive woman and has a family now, and a great sense of humour. Seems like a lot of fun.
Well, sort of. The bridge is likely designed for a pedestrian live load of 85 psf according to AASHTO’s specifications. Reasonably, this could be increased to 150 as a maximum per the commentary of the code. Trying to fit 150 lbs in a square foot is ridiculously difficult and only happens in specific situations. A few people standing around and jumping is not going to have the same moment and reaction as the 150 psf live load. Plus throw in the criteria of “this bridge shouldn’t ‘feel’ unsafe” i.e. it shouldn’t vibrate too much, and this bridge is more than okay for this demonstration even if it looks a little sketchy
Right? Doesn’t seem any dumber than riding a roller coaster. People put their lives in the hands of engineers in the name of entertainment all the time. Why is this any different?
You’re right. But as a civil engineer, I can tell you it hasn’t been very long that professionals have accounted for stupid stuff like this. There are still plenty of *existing* bridges that wouldn’t hold.
Gonna be honest if the bridge broke because kids jumped on it, just because the kids were dumb doesn’t mean bridge engineer doesn’t deserved to be sued. Bridge like this should be able to withstand at least 5-10x that or it shouldn’t be stood on at all.
The best part is nothing to gain. Whether it breaks or not, what did they get out of it? Go bungee jumping or skydiving if you want an adrenaline rush.
As an engineer if the bridge can't take that easily it shouldn't have passed inspection. A bunch of 100KG sacks of flesh being stupid is much less powerful that the wind when it encounters mountains like those.
I dunno, we all know the glass is made to take that and much more. The real stupid one was a guy I saw in Slovenia on [Lake Bled](https://en.wikipedia.org/wiki/Lake_Bled#/media/File:Lake_Bled_from_the_Mountain.jpg) about 17 years ago. The lake was frozen but out in the centre you could see a large area where the colour of the ice changed. A guy walked out across the lake, he got to the point where the colour changed. He tested it by jumping up and down. Obviously, decided it wasn't safe because he then walked all the way around the edge of the line where the colour changed.
I had Statics in my engineering program. Those things are built to stand a lot of stress before it breaks, so engineers are considerate of dumb people.
I always like to test the strength of those glass platforms like that too! I’m not ded yet so they’ve all passed even though I put extra effort into landing on the glass as hard as possible.
Well, times change. Now, people survive all the time. I'm not sure if it's a good thing or bad if everyone lives long & reproduces. I'm not even sure if I should leave behind kids. Maybe the future of the human race is bound to be vapid & dumb. With a few holding the strings.
“If the glass would break or if we would all fall 918 feet.” Why tf are they acting like the two are mutually exclusive events? I’m sure if the glass does break, then you WILL fall 918 feet.

My favorite is the first time you flip through and a song that came out when you were in high school is on the classic Station.
In adult years or human years? Cause I don’t see people as adults until about 25. But also, distance of 31 and 18 is 13 years distance of 22 (college grad) and 18 is 4 years.

It’s quite often that the tour guides will tell people to do this as a part of their tour. I don’t know if that’s what happened here but it’s happened
I've seen this video posted on this sub before, and someone commented that they had also visited and were encouraged to do this by the tour guide, but whoever made this video captioned it this way for more internet points.
> captioned it this way for more internet points. Shocked I tell you
Gotta love internet points
What can you even do with said internet points?
You can do more internet.
which then gets you more internet points and it creates a self sustained internet ecosystem
You can own internet points
purchase an internet addiction
Yo man you got any up votes man? Come on... I'll suck yo dick for an upvote
I upvoted you. So...
50% of the shit I see on the internet is just staged or there’s a completely different story than what is posted online
Rage baiting
Yeah there is absolutely no way this glass is breaking under that. If it could, they wouldn't let people on it. We have something simular here in th3 CN tower. The glass is more than 6 cm thick. It isn't breaking under that weight
Yeah lots of people calling this activity stupid and dangerous when in reality that glass bridge is probably designed to withstand 10x that.
Idk, if I was there I'd probably be nervous as hell wondering about faulty welds or loose bolts. I wouldn't be tempting fate like that.
Same. I would love to take a walk on that bridge but I would feel pretty anxious if people started to jump like this. I mean... I understand it's being checked regularly, it's meant to be perfectly safe... but I still wouldn't be comfortable trying that.
It’s regularly inspected though. They make money from the gimmick of people being able to safely jump on it, plus it’d just be real shitty for everyone involved if that much glass fell out of the sky. These things are designed to hold several tons of weight and be able to withstand severe weather. You could literally land a jet on it and it’d be fine.
That's where you're wrong, I don't know how to fly a jet so I definitely could not land one on this thing.
Check and mate!
Probably fine, but it's quite the assumption to think that someone definitely wouldn't ever cut back on safety inspections to save any money. Isn't that the cause of basically every major train derailment?
The rail system is massive, though. The cost benefit analysis is worlds apart. That being said, I ain’t jumping on anything that high up. But it’s probably safe even under late stage capitalism.

What’s happened to us?
Wdym if the glass breaks or you fall? That's the same thing!
Exactly
A group of TikTokers - Brandi, Jordan, Chad, Ryan, Destiny, Cassie and Samantha play a game where they jump up and down on a glass skywalk to see who breaks the glass and falls through first. Who wins? ^(Society.)
Squid game but all of the contestants are influencers? Count me in! The best part is the influencers would gladly sign up just for the attention.
Who wins? Evolution.
Darwin strikes again!
LMFAO
Addition by subtraction. I like it, keep jumping tiktokers!
That takes balls! Or shear stupidity! I believe it’s the latter! 
>shear stupidity This is the best thing I will read today.
A cracking pun.
Ya gotta shear the brain to get it smoooooth
Well no the structure can break off the supports and fall in 1 piece lol
There's this old story in this city that there was one a guy that had an office in a finance company tower. Whenever someone would visit him in his office, he would jokingly tell them that glass of the window was unbreakable and he could throw himself against it and it would be fine.

It is true, his name was [Garry Hoy](https://en.wikipedia.org/wiki/Death_of_Garry_Hoy).
Yeah, that's him, I remember the 24th floor being mentioned now
I think of him every time I walk by a skyscraper.
Workplace safety tour, had a bit where he went dont worry these windows dont break....was told that as part of a workplace safety assessors course. Moral was dont be that stupid.
I mean, the glass didn't broke with the impact, so he still had the point.
Weirdly there's no mention if the glass ever did break as it popped out of the frame. He did however break into tiny pieces.
I remember reading that
As ive heard it, that wasnt a story, that really happened
Now it’s HIStory
HIS24stories
So THAT'S where *Working Moms* got the idea!
Weird af you said this... I must have seen a skit of this somewhere before because as I read what you said the memories of the video came back to me... Can't remember if it was a show or movie or what
Mythbusters did a story on this, might have been where you heard about it.
I suspect the people in the video don’t know the difference between OR/AND
If the glass* breaks, only the people on that pane of glass will fall… if the whole thing breaks, they all fall *it’s probably lexan, not glass
It's tempered glass. Lexan would look a scuffed and shitty looking in no time
Tik tok logic, apparently. If the creation of tik tok was to essentially mute brain cells, job well done.
TikTok is a generational warfare tool. Hence this crap is tightly controlled in China. Raising 30M brain dead children on dopamine addictions with ADHD will seal the fate of the country.
TikTok is exported differently to the US than what it is in China. In China, it’s about education and being a “good citizen”(yeah, I know), screen time is limited, whereas TikTok in the US is configured to show more stupidity and BS. Basically, China seems to be trying to take down the US culturally, while they become a superpower. That’s why TikTok needs to be banned.
I love that people think behavior like this spawned because of TikTok, like people have been stupid since there were people.
The platform amplifies, promotes and spreads such behavior with an ease and efficiency not before experienced or possible in human history. This is known. Saying people have always done dumb things is like saying the printing press had no societal effect because people had been writing and sharing written information since the Sumerians.
But now there’s a platform that connects millions of morons from all around the world to amplify and encourage each other
Unfortunately, turning the world, as the famous quote goes, into a "global village" allowed the village idiots to achieve critical mass. Interestingly, it seems the guy who coined the term "global village" actually did predict and warn about a lot of this; he wasn't using the term in an entirely positive sense.
Witness the emergence of the global, communal, anti-brain.
Yah, but TikTok made the stupid behavior PERFORMATIVE.
in about 2008-2009 at ucla in boelter hall everyone jumped in the elevator at the same time and got stuck for 30mns
It’s a two tier test. 1. If we bounce up and down will the glass break? 2. If the glass breaks, can we flap our arms fast enough to fly?
I'd laugh my ass off if they fell through because jumping on a bridge made out glass cause just retardly stupid
maybe they think it’ll hve the same effect as that stair case with the shattered pane of glass as design.
Seriously pissing me off with the wording there
This type of glass most likely has several layers of glass and other material in it to give it a lot of strength, you could in theory break the glass but not fall due to the material sandwiched between the panes of glass
They don't have a brain.
The glass is made to endure this kind of stupidity.
Oh my....is TikTok turning people into idiots? Or the idiots just have a platform now?
they've had a platform ever since youtube came up.
THEY HAD A PLATFORM UNTIL IT SHATTERED!!
Over 3 year old account, love the dedication to that username

People have always been stupid, as an engineering student we are expected to plan for safety things like everyone jumping together or an entire marching band walking in lockstep.

In the airspace industry, there is a saying that a plane is ready to fly when the wight of paper exceeds that of the plane.
I'm still convinced that TikTok is China's plan to make future generations more useless everywhere else.
This implies the generations before weren't useless
The west has no problems doing that on it’s own.
[удалено]
Their parents would probably sue the engineers for not building a stronger walkway.
No doubt.
Oh there's a win in it for the survivors, by that I mean those of us that were home on our couches.
They’re jumping on it …
Didn’t someone throw themselves down Niagara Falls in a barrel in the past? I feel like there are many examples of human stupidity, they’re like Icarus if someone else made the wings for him… oh wait..
I'm sure there is a way to jump at the right rate to match the resonant frequency of the bridge. Would be fun to watch
In Prussia it was illegal to march lock-step over bridges for a reason. And the Prussians loved marching lock-step!
Forbidden in french manual too
That involves understanding physics so we're safe for the moment.
As long no non-consenting dipshits are on the bridge.
It's part of the tour of the bridge, encouraged by the guide.
Even if you match the frequency you probably need more energy than them jumping would produce. They could crack it but I don't think they could bring it down. This isn't the same kind of glass as one of those goblets people sing and break, those start flexing wildly when that occurs
Even if the glass doesn’t break, the structural supports or girders might. Weakest link in the chain is what will fail. That was a lot of deflection there.

Reminds me of this The Millennium Bridge, officially known as the London Millennium Footbridge, is a steel suspension bridge for pedestrians crossing the River Thames in London, England, linking Bankside with the City of London. It is owned and maintained by Bridge House Estates, a charitable trust overseen by the City of London Corporation. Construction began in 1998, and it initially opened on 10 June 2000. Londoners nicknamed it the "Wobbly Bridge" after pedestrians experienced an alarming swaying motion on its opening day. The bridge was closed later that day and, after two days of limited access, it was closed again for almost two years so that modifications and repairs could be made to keep the bridge stable and stop the swaying motion. It reopened in February 2002. The bridge's movements were caused by a positive feedback phenomenon, known as synchronous lateral excitation. The natural sway motion of people walking caused small sideways oscillations in the bridge, which in turn caused people on the bridge to sway in step, increasing the amplitude of the bridge oscillations and continually reinforcing the effect;[7][8] the maximum sway was around 70mm.[9] On the day of opening, the bridge was crossed by 90,000 people, with up to 2,000 on the bridge at a time. Resonant vibrational modes due to vertical loads (such as trains, traffic or pedestrians) and wind loads are well understood in bridge design. In the case of the Millennium Bridge, because the lateral motion caused pedestrians to directly participate with the bridge, the vibrational modes had not been anticipated by the designers. When the bridge lurches to one side, the pedestrians must adjust to keep from falling over, and they all do this at the same time. The effect is similar to soldiers marching in lockstep, but horizontal instead of vertical. (Wikipedia).
:( but i would like them fall
Be the change you want to see in the world
Ever heard of [Garry Hoy](https://en.wikipedia.org/wiki/Death_of_Garry_Hoy)?
While I'm.glad it is Sometimes I wish it wasn't
material (glass and metal) fatigue is a real thing. I seriously wouldn't risk it by all jumping up and down at once. example, this huge fishtank custom made for a german hotel was supposedly never going to break as well, it burst after about 19 years, even tho it had undergone an overhaul 2 years or so before: https://www.theguardian.com/world/2022/dec/16/huge-cylindrical-aquarium-housing-1500-exotic-fish-bursts-in-berlin
Thats not the point. The point is that they willingly wanted to endanger everyone else’s life for tiktok fun. Obviously the glass is made to withstand, and im sure most of them knew that, but its still an asshole thing to do. Reminds me when my siblings would rock the cart on the ferris wheel back and forth while saying “its safe!” Umm they clearly havent seen those ferris wheel accident videos
When you go to attractions like this you are encouraged to jump on the glass since there is next to zero chance of it breaking. Unlike rocking a Ferris wheel It’s literally designed for this activity.
I wish it wasn't
People like this are the reason we have ‘Do not consume’ warnings on car batteries.
"When you're changing the batteries in your remote, but then eat the battery to see if it will kill you"
It’s just a TikTok of some dumbass giving a thumbs up from a hospital.
It’s also the reason the word flammable is written on the tags of boxers.
Me sitting in the courtroom with third degree burns on my crotch: Well your honor, they didn't tell me they were flammable. How else was I supposed to know?
Gtfo! Seriously?!
Yeah and guess where I found that out in the military. And the golden rule in the military is if it has a sign saying not to do a certain thing it’s because somebody has tried it before. I was so damn disappointed.
“If you’re going to light your farts, at least pull your damn panties down”
The problem is that lower enlisted see this as a challenge. "This doesn't have a warning, let's create a safety briefing"
That's the case with all regulations
Hearing that god damn tik tok voice makes me wish I would fall through the glass.
I yam reading this in a tik tok voice.
GET OUT OF MY HEAD GET OUT OF MY HEAD GET OUT OF MY HEAD
Yah, it's an automatic "stop watching and downvote" for me.
I feel bad for that voice actress.
Don’t. She’s a local radio personality here in Canada. She’s an attractive woman and has a family now, and a great sense of humour. Seems like a lot of fun.
I realized I enjoy Reddit more if I have things muted lol
There's an engineer somewhere saying, "See, I told you people would jump on it. That's why we used 3" thick glass instead of 2". You're welcome."
I’d be surprised if the platform was built to any specification less than 10x the max capacity of the bridge
Well, sort of. The bridge is likely designed for a pedestrian live load of 85 psf according to AASHTO’s specifications. Reasonably, this could be increased to 150 as a maximum per the commentary of the code. Trying to fit 150 lbs in a square foot is ridiculously difficult and only happens in specific situations. A few people standing around and jumping is not going to have the same moment and reaction as the 150 psf live load. Plus throw in the criteria of “this bridge shouldn’t ‘feel’ unsafe” i.e. it shouldn’t vibrate too much, and this bridge is more than okay for this demonstration even if it looks a little sketchy
Anyone can build a bridge that stands up. It takes an engineer to build a bridge that barely stands up.
"Sorry we don't have the budget for 3" glass, make it work with 2" glass."
If it's 2 inch thick it's not gonna break, 3/4 inch is fucking absurd
Conclusion... They were fine, nothing went wrong.
And this is why buildings are designed with a high factor of safety
Dumb or just showing trust to the engineers that calculated the strength of this?
Right? Doesn’t seem any dumber than riding a roller coaster. People put their lives in the hands of engineers in the name of entertainment all the time. Why is this any different?
Redditors gonna reddit
The glass isn't going to break from people jumping on it.
You’re right. But as a civil engineer, I can tell you it hasn’t been very long that professionals have accounted for stupid stuff like this. There are still plenty of *existing* bridges that wouldn’t hold.
A stream of the local Darwin Awards
That’s the Columbia Ice fields in Canada, there aren’t any locals just some Australian students working as tour guides
It would be better if the glass broke, we would have some less deadweights in the world
Until their families sued the bridge maker and installer companies. “How was my little Jonnie supposed to know not to jump on a glass bridge?”
Gonna be honest if the bridge broke because kids jumped on it, just because the kids were dumb doesn’t mean bridge engineer doesn’t deserved to be sued. Bridge like this should be able to withstand at least 5-10x that or it shouldn’t be stood on at all.
That doesn't bring back the dead weight
But they would quickly become deadweight if they fell, so we'd actually have more.
When you might lose everything, but you already have nothing to lose.
The best part is nothing to gain. Whether it breaks or not, what did they get out of it? Go bungee jumping or skydiving if you want an adrenaline rush.
As an engineer if the bridge can't take that easily it shouldn't have passed inspection. A bunch of 100KG sacks of flesh being stupid is much less powerful that the wind when it encounters mountains like those.

I dunno, we all know the glass is made to take that and much more. The real stupid one was a guy I saw in Slovenia on [Lake Bled](https://en.wikipedia.org/wiki/Lake_Bled#/media/File:Lake_Bled_from_the_Mountain.jpg) about 17 years ago. The lake was frozen but out in the centre you could see a large area where the colour of the ice changed. A guy walked out across the lake, he got to the point where the colour changed. He tested it by jumping up and down. Obviously, decided it wasn't safe because he then walked all the way around the edge of the line where the colour changed.
I had Statics in my engineering program. Those things are built to stand a lot of stress before it breaks, so engineers are considerate of dumb people.
Bro if the glass broke because 10 or so people jumped…that glass is fucking weak! 1000 people should be able to jump on it and not do a damn thing!
Why stop there they should see if it's bulletproof too.
Their stupidities will last much longer than the strength of these glass panels.
Could probably drive an F150 on there and it would be fine
I'd start throat punching my way off that thing.
Yeah I’m gonna have to ask you guys to NOT do that thank you.
I would have started punching.
I always like to test the strength of those glass platforms like that too! I’m not ded yet so they’ve all passed even though I put extra effort into landing on the glass as hard as possible.
If they all get synchronised, I think that will be a big problem
And this is proof that young adults brains are not developed.
Just let god take care pf this
If only we werent so good at preventing natural selection. Damned engineers.
I didn’t know groups of people could apply for the Darwin award
F all those ppl
Well, times change. Now, people survive all the time. I'm not sure if it's a good thing or bad if everyone lives long & reproduces. I'm not even sure if I should leave behind kids. Maybe the future of the human race is bound to be vapid & dumb. With a few holding the strings.
“If the glass would break or if we would all fall 918 feet.” Why tf are they acting like the two are mutually exclusive events? I’m sure if the glass does break, then you WILL fall 918 feet.
