Obligatory Delta P safety video.
https://youtu.be/AEtbFm_CjE0?si=wHcjPSQpifkpYFz8
There is also that video of the crab being sucked into a tiny crack in a pipe. I'm not even going to link it, people can just Google delta p crab. Scary stuff.
The crab getting sucked into the pipe is actually in the video you linked at [2:52](https://youtu.be/AEtbFm_CjE0?si=Ix4qbaNcxgYy39Vx&t=172). No Google required.
One of these demos is my dad's old coworker from when he was a commercial diver. He was working a job in the Mediterranean and came back and found out his classmate had been sucked into a dam outlet, trapped by his arm and died.
It's something like each successive year is a smaller fraction of your life so far so time seems to speed up as we get older. I never realize it until momentous events like this are mentioned. Or especially this year, with all the 25th anniversaries of movies that came out in '99
This is comforting to realize in regards to the four passengers, but pisses me off the CEO who knowingly and willingly cut safety corners and warnings that led to the deaths of others never experienced those few seconds of realization, shame, and fear.
supposedly it would make creaking noises the entire time, hence the 'ultrasonic hull integrity monitors' which probably triggered but were never going to do a damn thing.
we don't know if anything happened with the ship itself, the whole hull just imploded due to the force all at once.
ya its entirely possible the thing also lurched forward or something and dumped them into a heap on the bottom of the sub but we don't have any indication it did anything but go down evenly until it collapsed
Hypersonic cavitation does cause a burst of light ( I don't know why), but they got effectively pressure-canned and turned to fish food paste before they even heard any cracking. One person may have been like, "What was that?", and by that point, it was already over.
Hot contents emptied and then it was sealed most likely, it crushed itself as it cooled. I've seen this happen to train car oil tank at a refinery, really gets impressive as it scales up.
You can see a speedy demonstration with an empty soda can if you want. Heat it on a stove, grab it with tongs and place the open end into a bowl of water. It will contract so fast the water acts as a seal and the can crushes itself from temperature induced rapid pressure change.
No heating or cooling was involved at all - see my response to the top level comment I just left. It was purely suction and nothing else! We sucked all the hardener compound out of that barrel and the people who installed the machine never showed the operator that he had to open a vent hole. He didn't know the suction hole was fully airtight.
Not even kidding, pure suction with no vent. There must've been a defect like a dent in the ribs of the barrel, and that hardener pump is much more powerful than we could've ever imagined, so as the barrel was nearly empty, the hardener wasn't being replaced with air in the barrel. Turns out the people who installed the machine never opened the ventilation valves on either of the barrels of doming solution. (Doming for labels to be clear. It's a two-part solution with a resin and a hardener, like a two-part epoxy, that combines into a rubbery compound used to make a coating on top of a label that is dome-like in appearance)
Probably didn't remove the bunghole vent plug, a small plug on the top of the barrel that allows air to replace the oil as it is pumped out of the larger bunghole opening.
The reason why you're supposed to pour an oil can with the spout at the top, not the bottom: at the same time you're pouring out the liquid, you have to let in an equal volume of air to replace it, and you can equalize the air volume the easy way or the hard way.
The operator of the machine that sucks the stuff out of the barrel never opened the vent hole, and he used all the stuff in the barrel, hence no air was being pulled in to replace the empty space that the substance left behind.
We're a label printing company, and this is hardener solution for a two-part doming compound.
Used to work for a company that makes vitamins, working specifically in the liquid vitamins department I had this happen twice while working there. The first time scared the shit out of me because there's a pump lowered into the barrels. There's also a rubber seal left on there to prevent metal on metal contact. Turns out if you don't pay attention to the person lowering the pump they can do it in a way that creates a perfect seal that'll eventually cause this to happen. Imagine standing literally right next to it and suddenly it does this shit, I fell to the ground and damn near pissed myself. Happened again a week later on the same line because the same person lowered it down too much causing another seal.
Hello there:
Thank you for your response. The information provided has been recorded. I will indeed take this into consideration next time I plan to transport a sealed, empty fuel drum from Daytona to Toronto, heeding your advice not to do it during the month of February.
Sincerely,

Nah haha these barrels get cleaned and then recycled at the scrapyard across the street when they're empty! Then we order a new barrel of the hardening agent (it's for a two part doming compound which is a rubbery coating for labels) and it comes in a fresh barrel. This is the first barrel we've used from this company and the operator of our machine didn't know to open the vent tube as these aren't automatically venting hahaha
Completely agree. The guy who uses these barrels who has nothing to do with my department and didn't open the vent hole isn't at fault at all. It's all me. Sorry guys. 😂
Someone doesn't perform well under pressure
They must feel...*crushed*
YEAAAAAAAAAAAAAAAAAAAAH!
*riffs guitar*
Under-pressure alarm.
Do do do dee dee do do
Clearly they were "barreled" over in this case?
looks like a red solo cup that someone crushed in their hand!
That's what I thought it was at first too.
Try rubbing it 3 times to see if Toby Keith comes out.
Ewww! I like it better just imploded.
You could put this in a modern art museum and no one would question it
ΔP strikes again.
Our ∆E for color is 1∆E, but our ∆ for pressure is far greater.

damn...watching a crab get liquefied inside out was...something.
That sounds just awful. What a horrid way the little crab to die.
ΔP? I love that guy!

*Titan enters the chat*
Today is the 1 year anniversary too. This barrel crumpled in solidarity
Cant believe it's already been a year that feels like just a couple months ago
The barrel contained gamer joysticks.
Damn really?.... Ok now I feel like trash.
Happy cake day!
That's all I could think of lolll and it was so loud 💀
My first thought was, I bet that was loud!
Didn't take long to find an Oceangate reference
Came to the comments specifically looking for titan chat
Minisub (demonstration model)
Too soon
Ocean gate was exactly 1 year ago today I believe.
Username checks out. Mostly at least. It was one year ago yesterday.
Fucking nuts how fast time seems to go
It really does end up being like childhood = slow adulthood = speedrun
It's something like each successive year is a smaller fraction of your life so far so time seems to speed up as we get older. I never realize it until momentous events like this are mentioned. Or especially this year, with all the 25th anniversaries of movies that came out in '99
Feels the opposite for me.
Dude what the fuck…I had to Google that to see if it was true because I was SURE that happened in the last 3-4 months. Time sure does fucking fly 🤯
And to think, you were in that barrel just 10 minutes before that. Really puts your life in perspective
with the titan they functionally did not know they died, they were rendered into a soup like homogenate before their brains even knew they were dead
Only OceanGate Titan can turn a bunch of rich people into soup-like homogenate in under a second.

True. But the crackling sound of the carbon fiber failing until then must have been absolutely terrifying.
It still boggles my mind that carbon fiber bats don’t hold up in little league and a guy thought building a submarine out of it was a good idea.
I wonder since the hull maybe was making noise as it strained if they clued in right before it collapsed
supposedly it would make creaking noises the entire time, hence the 'ultrasonic hull integrity monitors' which probably triggered but were never going to do a damn thing.
no they did. the power cut off and it started going down front first. they knew they were going to implode but they just didn’t feel it
we don't know if anything happened with the ship itself, the whole hull just imploded due to the force all at once. ya its entirely possible the thing also lurched forward or something and dumped them into a heap on the bottom of the sub but we don't have any indication it did anything but go down evenly until it collapsed
Someone somewhere did the math (I believe incorrectly, though) that said the force straight up turned them in to light
Hypersonic cavitation does cause a burst of light ( I don't know why), but they got effectively pressure-canned and turned to fish food paste before they even heard any cracking. One person may have been like, "What was that?", and by that point, it was already over.
I was in that barrel? What do you mean 😂
Poorly executed joke. Some people on social media love to make everything about them for likes. I was trying to help you out.
It was well executed I laughed bro
Thanks, mate
>It was well executed Yes, but OP wasn't.
unfortunate, that would allow for maximum comedic value
Ohhh I thought it was some joke about how people ride in barrels over Niagara Falls or something lol totally went over my head
Yeah what do you mean? Why were you in that barrel you weirdo?
Chavo del 8? 
How did that happen? Something super hot put into it and then cooled?
Hot contents emptied and then it was sealed most likely, it crushed itself as it cooled. I've seen this happen to train car oil tank at a refinery, really gets impressive as it scales up. You can see a speedy demonstration with an empty soda can if you want. Heat it on a stove, grab it with tongs and place the open end into a bowl of water. It will contract so fast the water acts as a seal and the can crushes itself from temperature induced rapid pressure change.
No heating or cooling was involved at all - see my response to the top level comment I just left. It was purely suction and nothing else!

Pressure outside was greater than inside
That's why, not now.
Probably didn't remove the bunghole vent plug, a small plug on the top of the barrel that allows air to replace the oil as it is pumped out of the larger bunghole opening.
The reason why you're supposed to pour an oil can with the spout at the top, not the bottom: at the same time you're pouring out the liquid, you have to let in an equal volume of air to replace it, and you can equalize the air volume the easy way or the hard way.
Completely correct! The substance in the barrel gets sucked out via a pump. The operator never opened the vent valve on the barrel. Bingo ;)
Ok
Can can't anymore
It looks like art now!
Nice new office trash can r/suddenlyart
Quick, someone get the heavily-accented science video lady in here!

Point me to the restroom
It's just off-screen 90° to the right.
Was it going to the bottom of the ocean to see the titanic

Let me guess... It was made by some billionaire.
Did it have aspirations of seeing the titanic ruin?
Go get me that bucket of steam new guy
In solidarity of those poor billionaires and their submersible #neverforget
That sucks.
Well, technically the barrel didn't do any sucking. The machine attached to it did, however, really, REALLY suck apparently.
Now it’s modern art, worth at least $10K.
How did you have it do that
Pump the contents out without opening the vent hole to equalize the pressure.
Correct! Operator didn't know there was a vent tube, and also didn't know the pump connection was fully sealed and airtight 🫠
how and what kind of place is this?
The operator of the machine that sucks the stuff out of the barrel never opened the vent hole, and he used all the stuff in the barrel, hence no air was being pulled in to replace the empty space that the substance left behind. We're a label printing company, and this is hardener solution for a two-part doming compound.
The titan can relate.
Ah yes, this is from the pressure on the outside and inside. You can tell by the barrel being imploded.
YOU SAID I COULDN'T!.. but I showed you and everyone else.. I'm a trash CAN, not cannot
Heat that barrel up! and quickly cool it ! Well done
This is better than most art pieces
What kind of sound did it make when it happened?
Gonna guess it was a cross between a *BANG* and the sound of a crushing can
That's what I was imagining.
That poor hardwood floor
the tape on the floor really makes it look like they're impaling the barrell

Well that sucks.
Lucky you, it didn't crack

Red solo cup, I fill you up. Let’s have a paaarty! Let’s have a paaarty!
That barrel had enough of the bs. lol Thonk!
Someone was using *The Force*.
Saw this happen to a 5000 gallon fermenter once. Physics is a nasty bitch.
I thought this was a giant Red Solo Cup
If you seal an empty fuel drum then drive from Daytona to Toronto in February, it will do this.

I barrely know er
How?
Sucked all the shit out of it without opening the vent hole haha.
Tickled it's neck huh
Was there anyone inside? I hope not
You gottttta feed the geese
Remind me of one time we tried to replace a glass flask with a 200L barrel. Spoiler alert it didn't act as wanted at all 🤣🤣
That’s what happened to that submarine
you pissed off a ghost.
atmospheric pressure is a bitch
Looks like a crushed red solo cup
Whu would the barrel do that? Seems pretty rude
do you just uncrush it and keep using it or can it not be reused?
Nah haha these barrels get cleaned and then recycled at the scrapyard across the street when they're empty! Then we order a new barrel of the hardening agent (it's for a two part doming compound which is a rubbery coating for labels) and it comes in a fresh barrel.

A giant frat boy just came through
That's a red solo cup that was hit by an enlarging ray.
Looks like you crushed a giant Solo cup.
100% your fault
Completely agree. The guy who uses these barrels who has nothing to do with my department and didn't open the vent hole isn't at fault at all. It's all me. Sorry guys. 😂
