- Crushing Water With Hydraulic Press with 2000 bars / 29 000 psi pressure with our custom made cnc machined billet cylinder. With this extreme pressure twice the amount of deepest point of the ocean Mariana trench has or 5 times the pressure at Titanic wreck. This is more than any submarine / submersible or dive watch can take.
There is also some deep sea implosions from our older video shown on the video as an examples of the effects in our pressure chamber with these extreme pressures and depths

BEFORE COMMENTING that water can't be compressed READ THIS:
You can compress water (google if you don't believe) with this pressure it compresses around 7%. Yes the seals stretch and even the cylinder might stretch couple hundreds of a millimeter adding to the movement of piston but the water under the piston is supporting the whole 150 tons of force. Pressure is force / area so the pressure must be 2000 bars and water compresses always same amount on same pressure and temperature.
So no matter what the cylinder, seals or Santa Claus is doing the water compresses 7% inside of that cylinder when being pushed with full power of the press :D
This has been first requested probably 7 years ago :D But here it finally is! Crushing water with hydraulic press!
This was actually quite interesting one to do and took two days of trial and error before getting this much done. Looking forward to continue with 5000 bar setup!
The 5000 bar one will be interesting.
Perhaps the compression was not from the water but the seals being flexed out in the bore and groves.
@@RolandElliottFirstG It has to be the water because at least we know that the water took most of the force. And the amount water compresses on given pressure is constant. The rest of the system also flexes some amount. Even the steel cylinder probably flexes some amount with these test but the water has to compress also.
@@aslijogjaNot gasoline, but a Diesel-Air-Mix. Although it could be extremely dangerous! 🤪🤦♂️
@@HydraulicPressChannel Ive been wondering for awhile, but where is your accent from? it sounds northern european, but i cant tell. It sounds really cool, tbh.
@@HydraulicPressChannel No, you need 20.000 bar to compress water by 5%. 5% would hardly be noticeable in your setup. The signifikant factors here are the seals, piston, cylinder and the gasses trapped in the water.
Does the water get hot when it's compressed? If it does it would be cool to crush it. Measure the temperature. Then let it cool down to room temperature and see if it becomes even colder when it expands. We could see if it behaves like the liquid in an air conditioning system.
Really good question! First I would like to say that it happens only with gasses but I think liquids usually don't compress so it might be just nobody talks about how they get hotter when compressing :D I have to do some research about this!
Elastic deformation so I'm pretty sure it will stay cold. Unless it change state but there is only one state of liquid water unlike ice.
Water is compressible, but pretty much when doing fluid dynamic calculations its considered incompressible. The reason being is you really need gravity to compress water in on itself, for example the oceans, the pressures at the bottom at significantly higher than at the surface, but the water doesn't have anywhere to go except down towards the center of Earth's gravity. Compressing water using some other method that I can think of is pretty much impossible because it's quickly going to find an escape method, violently.
@@memberwhen22 had to relearn that one during the titan Media coverage. Its 5% compressable.
@@memberwhen22 did you not see the part in the video where they compressed water? lol
I'd love to see an analog pressure gauge attached to the side of the cylinder. We wouldn't really gather any data from it, but it'd be fun to watch it pop!
AvE did that a lot in his old videos with his hydraulic pump.
good old days
@@spikester
With enough pressure, any material can be compressed, and compressed as much as you wish. The difficult part would be taking that material to either a white dwarf star, a neutron star, or a black hole.
The impressive thing is that these things are literally compressing a solid block of iron! Imagine taking a cannon ball and trying to shrink it in all directions with pressure. Now imagine a piece bigger than Jupiter, or even the Sun!
@@TimpBizkit on discovery say the metal who is in the car candle is maded from two stars combined in one befpre 13billion years and the waight of just tea spoon it wad more then the waight off our sun
I had the same question ❓
Wiw
O-rings are for static applications, Quad rings ( like you show near the end) are for dynamic applications like your piston and cylinder. Love the chanel and all the crazy things you crush 👊
Teflon quad seals, hydraulic fluid does not compress
You should try this in the winter. You might be able to make one of the high-pressure ice phases at -25 C and 5 kBar. You would know because the volume will drop significantly as the density of these phases is higher than that of water so it could compress by 20%
I keep reading all these low temperature ways of doing it and in my head hearing the crazy engineer I used to work with talk about another way, liquid water is compressible above 800° C but making a container that can withstand the pressure of the water at those temperatures, and then able to pressurise it further would be insane. According to my old coworker it was experimented with as a way to take large volumes of water into space while taking less space in the payload area, containment turned out to be too heavy though.
@chewbacawookie9696 Look at phase II ice in wikipedia, it will avoid embarrassing yourself with such kind of comments
make ice 9
it will be fine
Hmmm! There's a thought! DO the reverse! Put water in the bottom of the cylinder, put the piston all the way down, and then pull it up to draw a vacuum and see how much ice you get!
@@bwhog most uninteresting proposal ever. making ice in a over complicated under efficient vacuum chamber...boring
You where at the very top of what any rubber seal can withstand.
In high pressure labs, when they go for that kind of pressure or more, they stop using rubber seals and can't even use the high pressure seals that you've shown at the end. They use metal seals, because anything else is to soft.
You may try bronze seals.
Strangely enough, rubber seals don't work at super low vacuum levels either.
@@user-db5qd3wd6z They out gas. Very different phenomenon.
Pressure is pressure no matter if it is positive or negative. @@user-db5qd3wd6z
So like the metal piston ring seals in an engine...
@@JoeJ-8282 Pretty much, just rated for higher and sustained pressure.
1. Part of the problem you're having with this setup is that you don't have any pilot for your piston rod to keep the assembly from cocking in the bore. I've rebuilt quite a few cylinders, and even ones that were single acting with pressure only on one side, the non-pressure side had a pilot to keep the rod centered. I noticed that the first time you broke a seal. The piston went in crooked. That's going to lower the amount of pressure it can take before failure. If you built a guide that stands off the top of your rig to keep everything aligned, that would fix that part of the problem.
2. Those lip style seals can be sourced in very large diameter like this too (I've used them on telescoping forklift cylinders). You only need one for the downward direction, and possibly a wear guide in the piston to keep everything properly centered.
I'm not nearly as qualified as you but my assumption was that they had to be perfectly parallel to go in properly. It looked like many broke before or as it was being pushed into the bore.
If you manage to cool down water until it freezes, under these high pressure the ice will be denser than water and will sink in cold water...would be amazing to see that
If you lower the pressure the ice will be denser, not the other way around.
@@stinkiaapje cheeeezzz at least check the wikipedia bro
From my experience working on suspension components, I have to say that your method for "getting the air out" leaves a bit to be desired. Many sophisticated dampers which need to be *Completely* air-free will be designed with a bleed valve at the top of the chamber, or assembled while completely submerged. (In this case a bleed valve should probably come upwards through the top face of the plunger.) You can shake or tilt the cylinder while slowly cycling up & down with a reservoir placed above the cylinder attached to the bleed valve, or for faster results you could pull a vacuum on it to snatch the air--much like an automotive hydraulic brake line. Even the quality of water that you're using, if it's just from your regular faucet ,will be quite aerated. 1:39 I think i can see a bunch of tiny bubbles in the soda bottle before you start pouring. That is probably enough air to skew pressure and compression results on such a bold claim.
Also I've been watching you guys for over six years now and I'm so happy you still seem to have fun making such videos, and have so many subscribers!
What if you try to make your own glacier ice by chilling the chamber then crushing blocks of ice or ice shavings (snow)? You might also be able to create Ice VI or VII if you keep the temperature of the chamber and ice between 0°C and 75°C while at 150 tons of pressure
I think you need 22k bars for ice vi which would be 11x what he can do with that press
You can compress water, but you need much, much higher pressure. At 20.000 bar water will compress about 5%, and at 100.000 bar 15%. This is like "can you melt tungsten?" and then trying to melt it with a matchstick. Compressing material with water under high pressure, is actually being done in the food industry. Juice and other liquid foods can be pressure treated with about 3.000 bar after bottling, to preserve the product without chemical preservatives. It is called High Pressure Processing (HPP). The high pressure breaks down the cells of bacteria and fungi, without heat treatment.
You have shifted a decimal.
46 ppm at 1 bar @ 20C but it isn't linear.
Compressibility decreases with increasing pressure and increases with colder temperature, warmer water resists compression more. So it depends on whether the change is isothermal.
approx 4.4% volume decrease at 1,000 bar @ 0C 3.8% at 20C
approx 7.8% volume decrease at 2,000 bar @ OC, 6.8% at 20C
A couple of hundred atmosphere pressure wave is relatively easy to generate which is why water is not suitable as a hydraulic fluid, a 1% volume change in a mass under load is a problem for stability with oscillations etc.
I was completely unaware of HPP, so that is a 'learn something new every day'
thank you.
according to wikipedia,
" During pascalization, more than 50,000 pounds per square inch (340 MPa, 3.4 kbar) may be applied for approximately fifteen minutes, leading to the inactivation of yeast, mold, and bacteria."
"The treatment occurs at low temperatures and does not include the use of food additives. From 1990, some juices, jellies, and jams have been preserved using pascalization in Japan. The technique is now used there to preserve fish and meats, salad dressing, rice cakes, and yogurts. It preserves fruits, vegetable smoothies and other products such as meat for sale in the UK.
An early use of pascalization in the United States was to treat guacamole. It did not change the sauce's taste, texture, or color, but the shelf life of the product increased from three days to 30 days.[5] Some treated foods require cold storage because pascalization cannot destroy all proteins, some of them exhibiting enzymatic activity[13] which affects shelf life.[14]
In recent years, HPP has also been used in the processing of raw pet food. Most commercial frozen and freeze-dried raw diets now go through post-packaging HPP treatment to destroy potential bacterial and viral contaminants, with salmonella being one of the major concerns"
your hole to vent water at the top will damage the seals as they go over the hole especially with some pressure.
if you drill a small hole in the piston with a plug. push the piston in let water come out the small plug then seal it off then press .
another way is put a taper at the top of the cylinder to let water out until the seals go past the taper. that way it won't rip the seal.
Very interesting! To this day I was not aware that water actually compresses above a certain pressure. You live to learn 🙂
It compresses with any pressure increase, just not enough to measure until the pressure is quite high.
I’ve wondered about this since I was a child. Great work!
It’s more likely that you were seeing deformation of the cylinder or a small amount of trapped air in the cylinder causing that tiny amount of piston movement instead of “compression” of the water.
Yup. With these kinds of conditions we have to consider the air that naturally is dissolved in the water. That is going to compress before the "incompressible" liquid would. I'd still be inclined to believe water can be compressed with enough pressure, but it would raise temperature. I'd have to look up a phase diagram. I should know this, but all the water I ever have to think about is at physiological temperatures =)
@@kma3647 Water compressibility is approx 0.45% at 100 bar, 7.8% volume decrease at 2,000 bar @ OC, 6.8% at 20C
@@kma3647water can be compressed, simple as that.
Fluids can be compressed, look up coefficient of compressibility of a fluids
@@kma3647 If the air is actually in solution in the liquid, it won't be in the form of gas bubbles which can compress. Air bubbles can completely stop a hydraulic system from working (e.g. hydraulic brakes). Dissolved air does apparently have some effect on the compressibility of water (as does any dissolved substance, according to what i managed to Google) but nothing like the effect actual bubbles have.
If you get the water to around 9,000 bar, it should turn solid at room temperature. I've done it for my research in high-pressure mineral physics.
You may be seeing the result of elastic enlargement of the cylinder walls under pressure as well.
Could you also build something that can produce 30000 bars? Thats where water should turn into ice VII. Not sure how to verify its formation without a camera, but maybe that could be an interesting experiment.
I can prove it at the beamline P61B at the Deutsches Elektronen-Synchrotron using in situ x-ray diffraction.
that's 435,000 psi. steel will flow at that pressure so sounds very difficult . he only did 2000 bars so you want 15 times that .
@@ronblack7870 Yes it is a challenge. Generating that pressure is not difficult by itself (diamond pressing tools can create much higher pressures even if its only on a tiny area for example). The challenge will just be to build something that can actually contain the fluid at that pressure. There is no doubt that it will only be a tiny amount of fluid. But i think it might be interesting.
I look forward to seeing the follow up video to this one with those new seals, especially if you crush those watches you mentioned. That would be interesting to see. Sad maybe, (because I'd love to have one of those watches myself), but still interesting.
Nice videos you make. I would love to see a collaboration with the slowmo guys. Keep it coming. ❤👍👏👌
Compress a bed sheet, t-shirt, shorts, and few pairs of socks to make a big pill like those soakable expandable towel tablets things.
Great video!
I’d like to see some of those “indestructible” military/camping knives go up against each other or some different stuff. 💯💪🏻
Well done haha
Got some good video ideas I think would be worth a try:
1. If you make the tools freezing cold and then compress ice cubes in them, will it turn into water or one bigger block of ice?
2. If the pressure is high enough to compress water, could you implode an unopened glass coke bottle or similar sealed glass bottle?
Or try pouring water into a cavity in a really thick piece of steel, welding or sealing the hole shut and freezing it. See what happens if ice can't expand, or what ice can destroy if it can!
So funny story how I got here. I was sitting on my couch doing some computer work, and suddenly got a random urge to find out if water compressed. I thought surely no one has ever done it before as a it seems weird and difficult, but here’s this guys video! Real lifesaver for my random important scientific mind!
You quickly clarified that it was a "metric" shit tonne of pressure, good work.
I remember in an old National Geographic an article on Dr. William Beebe's bathysphere for deep depth exploration. Designed by engineer Otis Barton, the bathysphere was 4-3/4" in diameter with 1" thick steel walls, 3" thick fused quartz windows. During an unmanned test dive down to 2000' depth, the sphere had a leak in a third window, filling the interior. When brought to the surface, Beebe removed a bolt from the sealed hatch. The pressure of the water inside shot the heavy bolt across the deck, striking a winch 30ft away, creating a 1/2" gouge and a totally horizontal stream of high pressure water and air.
How did it maintain pressure when it obviously leaked ? :D
I can only assume that as the bathysphere was raised to the surface, the internal water and air pressure pressed whatever was loose back into place, sealing the leak.
While the water didn't compress, the air in the sphere did and that compressed air forced the water out when the bolt was removed. Beebe recounted that that water stream coming out looked like it had steam coming out of it.
If the bathysphere was just 120 mm in diameter, how could it fit a hatch with heavy bolts and windows? And it was supposed to be manned? Damn those freedom units are dumb...
For context, the water at the bottom of the Mariana trench is about 6% denser than water at the surface. Ask an engineer to explain that any time they claim "water is a noncomprehensible fluid."
The drill bit slo mo was really cool!
Send us Rolexes so we can test their pressure rating. Clever. ;)
If you want to make solid water, just put it in a vacuum chamber. It will boil and then stop. Once the pressure drops it will boil again until there is insufficient heat available from the surroundings, then it freezes. Physics stuff🤔
Thanks for your instructive channel. A literally cool experiment you can do is to keep the water cold. According to the water transition phase diagram, water remains liquid at 2.000bar till ~ -19°C!
Unless the water has had gasses removed, there's stuff in there besides water. Was the water boiled before being put into the cylinder? I believe this explains at least some of the compression.
That was really amazing thank you 👏👍
Lorey you never fail to make my. Day puety guud 😂
Can you crush a pine cone please would be happy if you do it
If you'll use the smaller cylinder, you might want to create a larger chamber that is connected to the small cylinder, somehow, so you have more room to work with. :)
What you have observed was seal compression and cylinder expanding. Try to compress liquid inside of high pressure fuel pump element without any elastic seals.
Keep up good work
Good up keep work
Can you add a stick on ruler to the piston?
Water is compressible, far more so than solids, but far less so than gases. When dealing with mixtures of gases and liquids, it's a convenient approximation to assume the liquid is incompressible. When dealing with water hammer in pipelines, the compressibility of water is a factor, along with stretch in the pipe walls.
This is very interesting!! I'm curious what that water temperature is when being crushed.
You are starting to simulate the pressures in the oceans inside the ice shells of the Jovian moons. Proper planetary science 🙂
Amazing video 😍😍😍
my idea for you😁
Machine down the threads of the bolt so that they can barely take the designed load, then put Teflon tape around the threads so that you can screw them back into the pressure chamber.
Finally, when the bolt pops out under pressure, see how much damage is done to the ballistic gel block ! 😆🤣🤣
I thought this also while filming :D I am going to build larger safety box and definetly test this one :D
Can you release some water with loosening the screw/bolt until the piston goes in with the seals ?
What happens if you try to crush items inside this chamber filled with non newtonian fluid?
Would the results be any different if you pressurised fizzy, carbonated water?
I am not sure, I have to try. I also realized that I can make EXTREME soda by forcing the co2 in with 300 bars on deep sea chamber :D
@@HydraulicPressChannel a sudden pressure release with carbonated water could be quite spectacular to watch, and quite messy :)
Once the CO₂ is fully dissolved everything behaves pretty much like pure water
I don't know much about the science, but I wonder if there is any separation of elements such as decomposition with heat. Very cool
Aw man, I really wanted to see it explode. Nice idea for the next video with the deep sea watches.
Now that I think about it, I'm not sure if the water chamber or the hydraulic fluid chamber would explode first, better either do it outside or build even more shrapnel protection
The water cylinder can't explode I have calculated that it would take 4 times more pressure than we are using here and the hydraulic press itself has also pressure valve to stop it from exploding
Thanks for this very good video 😃😃😃😁😁😁❤️❤️❤️👍🏻👍🏻👍🏻👌🏻👌🏻👌🏻
I love this channel
Wow there you go I always believed it wasn’t compressible ! Guess it pays to not read everything you hear .
I guess there is still small air particles in the water as water has oxygen in it amongst other parts, so it makes sense. There was a lot of deflection coming off your table when you let up tho so that would have added to the amount of spring back you had plus the metal itself all very small but it still moves as you most definitely would know . Love this channel!
No, not due to air or dissolved oxygen. All things are compressible. Gases are highly compressible, liquids moderately so, solids very slightly. Water is about 100 times more compressible than steel, gases (at ordinary atmospheric pressure) about 20,000 times more compressible than water (if I haven't cocked up my guesstimate). So for most applications it's convenient to assume that liquids are incompressible.
If you get air bubbles in a hydraulic system (e.g. a brake line) it can completely ruin the functioning of that system just because the bubbles compress so easily.
When you bend a steel bar elastically, the inner side of the bend is compressing slightly. A coil spring just makes use of that property in a more useful shape.
@@cr10001 thanks for the information mate , makes sense to me , cheers 🍻
It almost looks like the piston shaft is slightly bent from the pressure? I know the seals weren't liking it maybe check the shaft afterwards for straightness
Very cool
‘One metric shit ton equals 2,000 bar’ got it 👌
I've always wondered this for some reason
Every scientist: water is incompressible
Hydraulic press channel: hold my beer
6:38 the ironic "Nothing is going to leak" is priceless 🤣🤣🤣
Great video!
Thus, while water can be compressed, it requires extraordinarily high pressures to achieve even a modest reduction in volume, making it effectively incompressible for most everyday applications. We're talking about pressures in the range of hundreds to thousands of megapascals (MPa).
At the extreme pressures found in the depths of the Mariana Trench, water's density does increase slightly due to compression. The increase in density is a result of the water molecules being forced closer together under the immense pressure. However, this compression is very small compared to gases and is often negligible in many engineering calculations.
In theory the bulk modulus of water is 20 tonnes (20000N) per square centimetre, but I'm not sure how much it compresses if you put that much pressure on as it's only accurate for smaller compressions like compressing 1% with 200 kg/cm^2. It's probably why submersibles implode so violently if they fail, because if water had no compression at all, it would collapse at the speed it takes water to fall the height of the sub. Instead, the spring of compressed water tightly expands when there is a void for it to fill.
I think you should try crushing a sphere of plutonium...maybe with a little ball of polonium & beryllium in the center. I bet that would give interesting results! 🤯💥 But you'll have to up your game to a few million (billion?) bar I think.
You can’t just buy plutonium. If he tried that, he’d get arrested.
I wonder if you could make Ice II or Ice III with the press if you cooled down the container.
It would be good to put objects inside bottles and then compress them. When it is the objects alone, it is quite boring because they barely change. However, if they are inside a bottle or something that can withstand high pressure, the violent implosion might do more damage.
I worked on pipelines and they would pressure test certain sections of pipe with water. One day a pipe fitter removed the bull cap prematurely and was killed. Back then I thought the cap or wrench killed him but I guess it could have easily been the water itself. It was a 36 inch pipe if my memory serves, I wonder if the diameter of the pipe made it more dangerous or if the same would have happened with a pipe half the size.
I would hazard a guess with a pipe that large in diameter the actual pressure wasn't that high (compared to what is in the video) maybe 100-300 psi. But the force on the cap would be immense given the surface area. So probably more likely it was some object hitting them.
Nice test! Hieno testi! We have one problem. There is no relevant thermodynamic for liquid. If the liquid state does work, it cannot be calculated by Carnot's theorem. A heat engine of thermal expansion of a liquid is not reversible, because the thermal expansion of many liquids is greater than the value of compression. (bulk modulus)
Do you need a guide to keep it perfectly level? There might be too much torque directly at the seals.
Could you try to make type 2 ice?
Ice IV would be an interesting thing to make and other very high pressure forms of water ice.
Sponge. Crush a sponge.
Sponge Bob flat pants...
Can you do submarine type tests, where pipe connectors or other bolts break under pressure? Like in movies where submarines go too deep or are affected with pressure shocks.
What if you pressurized water and freeze it ? Will it be denser?
Isn't this whole setup basically a complicated hydraulic intensifier? Like why have the press at all, use the pressure from the hydraulic fluid directly!
It's not actually anymore complicated than real hydraulic component to achieve the same end result :D The things that raise the pressure (don't know the official term, is intensifier?) works usually with piston pump using two different sized pistons.
It's well known fluids can be compressed. It's all calculated for in hydraulic systems...however the amount of compression is miniscule so its accepted that saying it does not compress is the normal position.
Way back when I was in middle school, I told my science teacher that you can compress water, and he went off on me and said "you can’t compress water it’s the backbone of hydraulics" I felt like such a fool the way he spoke to me, I could never forget it.
Don't try this at home? Dang I just got my 200 ton hydraulic press from Amazon!
Lauri: these things are rated to 300bar, so, we're going to go only slightly over that...only very slightly though.
😂
Modify a ring compressor to prevent the last seal from being destroyed at the start of the stroke. Flaring the bottom of the ring compressor so it doesn't entire the chamber might be a challenge.
Make a static seal and pressurize the water by displacing it with a rod. Ceramic rod or stainless rod
OceanGate should have hired this guy
I used to pump water in metal chamber to 70 ton .
Put in styrofoam cup for maximum effect of shrinkage .
Use of 5 % glycol helps sealing .
The hole you put at the top seems to be damaging the seal. I would suggest letting the water out through the bottom fitting as you put the piston in so that you can get it all the way in before compressing the water
You should use that pressure and then freeze the water inside at that pressure. To see what the ice is like
You need a longer cylinder, a longer & more rigid piston that is more smooth and perfectly machined to fit tighter in the piston, after about 3-5 centimetres you machine a small tiny ring gap about 2-3 mm deep when you put the O ring . It should work.
What if you put a tube of toothpaste in a tranparent cynder and pressurize it
Good
You could try and do a really fast pressure cooker with the hydraulic press
did the CYLINDER yield or expand under pressure ???? perhaps putting a steel band with a dial gauge to measure the de formation of the cylinder... Maybe thicker walls needed and reinforcing ring made of a tougher material.. Have the grooves in the piston seal rounded over or changed shape??? perhaps a two-stage system with a locking piston. And then a pressure piston in the middle of a smaller diameter.. whatever happens this is going to get interesting🤠
I don't get why some people still say water cannot be compressed. It definitely resists compression but it can be compressed. Even ice self compresses if you get it very cold. I don't know if they are any exceptions other than water getting a little larger when it freezes but generally speaking if you lower the temperature or increase the pressure on something it will shrink in volume.
Try carbon seals. Connect a filling Reservoir to the top weep hole. Evacuate from the reservoir to remove all trapped gases from the liquid and the cylinder and charge the inter seal area with water. It would be interesting to try this with an air bearing that is filled with water or perhaps a thick petroleum product.
You should ask titans of CNC TH-cam channel for pressure chamber design ideas
Can you try this with metal seals?
if you drill a hole down the center of the plunger, you could put a plug on the water side of the piston that would be forced closed by the pressure. Then you wouldn't have to have any holes in the cylinder
you can make some rare crystal phases of ice by freezing water under pressure, try it next winter please.
Welcome to the Hydro-lic Press Channel and today we will be pressing water
If you can hold 5 kbar, you can make ice V which is an alternate form of ice with a different crystalline structure, you just need to cool it to -20 C @ 5 kbar
You might should try some kind of metal ring seals too, kind of like the ones in the pistons of internal combustion engines, as those might be more capable of withstanding that much pressure... As long as the tolerances of everything were extremely precise and tight fitting anyway.
Slightest bend when inserting will make it rupture
The pressure that piston rings must endure is very low compared to this - plus piston rings have a gap, they are not continuous.
You guys should put a circle mouth on the gel, it would look like the surprised faces from Thomas the Tank Engine and be hilarious 😂
What happens when you fill it with impure water? Like, if the Pepsi bottle you were using actually had Pepsi in it?
While water *is* compressible, what I think is more likely is that it was bulging the sides of the steel. After you release the pressure it starts leaking from the threaded hole.
