Very interesting video. It would be cool if Phantom lent you one of their cameras for a few days every couple of months - so you could get even slower slow-motion sequences like these. Stay safe out there.
They need to collab with Gavin from the Slomo Guys
No offense but that sounds like some commie gobbledygook
they're already using phantom cameras
@@z3cki They rent them occasionally - but if they had regular access we'd get more cool videos like this. Phantom must have a marketing budget - and lending HPC a camera occasionally would cost them peanuts. That's all I'm saying.
"welcome to the hydraulic press channel and today we are going see what happens when we crush this camera that Phantom gave us"
"What do you know about Finland?"
"...uh ...that's the heavy metal and Hydraulic Press country."
Also the only country to fully repay its ww2 debt!

Anni had a cool series of Finland Fridays. That's where I learned everything. Beyond The Press helps too. I can now count from 3 in Finnish.

I seem to remember an acrylic cylinder having a very energetic explosion under pressure. Might be interesting to see if you can do it under water. Pretty sure the cylinder would be nearly invisible right up until it exploded.
Dude your only comment on this is some weird scam thing that looks like it was typed by a Filipino man with schizophrenia.
I would also like to see the acrylic blow up underwater
It even has 3 subscribers
My theory is that the bubbles are formed when the surface of the item being crushed moves rapidly enough to create a relative vacuum. With that in mind it makes sense that vibrations/a shock wave would travel through the body of the socket when part of it breaks off, transferring energy to the liquid water it’s in contact with and thereby causing the phase change to a gas bubble.
Edit: this is specifically in response to why the cavitation bubbles appear on the surface of the small socket that’s crushed near the end of the video at 8:00 to 8:15.
the high speed of the parts trying to fly away pushes the water ,and the water is moving faster then the atmospheric pressure can push it back , the exact same thing happens when you hit a glass bottle that is filled with water from the top, it's simply the inertia of water
Yeah, I think your right. They are creating sonic booms but in the water
@@menkiboj the good ol method to force your buddy to start drinking faster
Cavitation
Yes exactly, it's so cool when the ball bearing goes, both tools move so fast at that point that the entire tool face creates cavitation bubbles just from the sudden acceleration
I like how pressing down on the ball bearing makes the hydraulic cylinder and the tool line up again.
Great stuff as always! New HPC videos are like my adult equivalent of Saturday morning cartoons lol.
As for an idea for the cavitation bubble thing.... I was thinking something like an air cannon, but smaller. You could take a Pringle’s chips can, cut the end off, and attach a rubber diaphragm to it... A stretched balloon would be perfect. Put it under the water, pull the rubber back and give it a pop, and you should get some BEAUTIFUL cavitation bubbles and rings.
That's a great idea. I will try something like that.
That isn't really Cavitation, its more like a vortex gun... Still cool though.
Cavitation bubbles are caused by water rapidly heating up and vaporizing... underwater. This can be caused by objects going super fast and generating lots of heat from friction, or by an explosion creating a void that the surrounding water rapidly fills in.
@@Wuzzup129 Bro i think you got something mixed up. Cavitationbubbles generate when the pressure drops below the vapor pressure. It typically has nothing to do with heat as far as their creation goes. But when they implode, thats when all the heat and pressure spikes occur you heard of. So the heat is a result of the caviation not the other way around. :)
@@ariferr7274 Ah.
Keep doing more videos like this. I love the experimental aspect of this channel. Doing experiments underwater is definitely a breath of fresh air.
only fish would say this
inronically enough , it is
7:47 Note that on the left side there is an oscillating bubble that started where there were a couple air bubbles. It looks to me like the shockwave caused the air in those bubbles to heat up to high temp and expand followed by collapse to a point where the air reaches high temp and maybe a tiny bit of water flashes to steam and the bubble expands again and repeat the cycle.
I hope you do a series with the Slowmo Guys one day, when everyone can travel again. With your knowledge of what does well on camera in a press and their high speed expertise, it should make for some really amazing video's! Imagine this at 250.000 FPS or something crazy like that.
What do you mean when everyone can travel again
@@doublew959 the coronapocalypse of course
That would be amazing. Get Destin involved aswell
Try crushing something that's piezoelectric. The charge it gets from being crushed should do some interesting things with the water's dipole.
Yeah, do it with distilled water and then with salt water
It would be quite the same as putting battery under water. Pressing piezo materials slowly creates low voltage.
But very quick snap under distilled water could do something interesting.

@@carlstanland5333 That's different phenomenon called triboluminescence.
@@carlstanland5333 yes!
Now that was a cool one!
Seems like underwater could have lots of interesting possibilities. I’m always fascinated by the cavitation bubbles oscillating- expanding and contracting, over and over.
I've been loving the under water crushes.
I would love to see a collaboration between HPC and The Slowmo Guys. The cameras you use are great and you do an awesome job, but this is Gav's area of expertise and I think we'd all like to see what he could capture with a phantom
He should collab with dank pods
i´m really amazed! that second slow-mo of the ball bearing was really something. i love, how there are 3 lines of shock bubbles forming - the one filling the central space and right after 2 circles from the shock bouncing off of the top and bottom parts of the press. really interesting.
So much energy in these things. Love it!
Curious to see you do this with the conical hardened tools to maximize the exposure area outside of the cavitation zone
These bubbles are probably water in vapour state: the explosion give enough energy to boil instantly water, which expands, and floats, and gets pressurised back, oscillating the walls of the tank, that are flexible and the surface oscillates, giving the woobing effect ont he vapourised water... The bubbles get colder and goes back to liquid state: the bubbles vanish. It's just a theory, but makes sense.
Holy crap that actually makes sense due to the amount of sparks from the ball bearing out of the water. It would be so cool if they showed how hot everything got when they're crushed
Very nice video with good energy - I have a feeling that this is indeed the beginning of a whole series of cavitation-related experiments, results of which I'm lookin forward to witnessing!
The bubbles could be steam generated, there is a massive amount of heat produced. ???
4:30 I think you're looking at an underwater sonic boom in slow motion there, explains the sudden bubble rush which quickly dissipates.
Best channel on the whole Internet! Great video. I wonder if a piezo element somehow could be used to create cavitation underwater.
It is possible that the immediate noise seen ("bubbles") are also tiny pieces of the bearings steel explosively moving through the water at a high speed. The water magnifies and tracks the particles leaving the appearance of the bubbles in conjunction with the regular bubbles that occur during high speed material explosions underwater.
It's been a while since I watched your videos and I must say that over the last year ya'll have SERIOUSLY upped the production value and ideas here!
👍 interesting stuff as always.
If you're looking for ideas - I think reviving your bridge idea could be a good one. 'major hardware ' has a really great long running thing called 'fan showdown' which is basically testing 3d printed fan designs on the same noctua hub.
It would be cool to see a series like "under pressure" where you have a set criteria (size of print, or weight or just length of span etc. That all entries have to conform with and then periodically do episodes throughout the year testing a bunch of the submitted designs
Super interesting. My guess is that the cavitation bubbles envelop the crushed item because it is the vibrations of the item what creates the low pressure regions.
Have you tried to crush a tungsten-carbide ball? They are expensive used mostly for ball mills.
This was so cool it blew my mind how different it looked ! Cool!
I love your narration. So educational. So relaxing.
its like that punching prawn causing cavitation
Punching prawn... I like that.
I mean, its called the pistol shrimp, but punching prawn seems more fitting somehow.

Thank you so much for this video.
I'm lucky to see the shock wave caused by the pressure.

I figured THIS ONE was going to be lame.AND then came the HIGH SPEED on ball bearing.Thnx,we needed that!
The bubbles or cylinders that look like air are vacuum space where the water walls rush outward, then back inwards and when the water walls collide they cavitate again. The cavitations essentially oscillate until they are damped out by the water pressure. Super interesting to see in this application at high speed.
A great way to get nice high speed cavitations is to make something implode under water, so a pipe full of air with sealed ends under pressurized water would do this. You could get a great shot in your pressure chamber.
thanks a lot for the frame-by-frame! That was the best part!
I love this channel !
I love the hū-draulic press channel even more when you crush härdenèd steel items. Love it!! ❤️
Wow! Very interesting video.
Never a boring day at Hydraulic Press Channel.
I do find myself missing the bonus content, dangerous clay crushing at the video end, though.
Awesome! Thanks for all the work guys! Been watching your channel since 2016.
Have you tried this in liquids other than water, like ethanol or liquid nitrogen?
Not yet but I have to try since so many people are asking about this. I think I should try something that has really high viscosity but it is clear like water.
@@HydraulicPressChannel
I think glucose syrup is pretty clear, and very viscous
@@HydraulicPressChannel astroglide is pretty clear like water 😏
Mineral oil might be a good choice.
"Crushing balls in lube!" will get you good clicks guys.
Great video, Lauri. That cavitation effect was very interesting. Cheers.
Woah those cavitations are amazing! The slow-mo looks really good too!
This is serious stuffl! What happens with two ball bearings, separated versus closet in? Will shrapnel from one trigger the other? When the ball fails, light is emitted! Add a littel fluorescein (uranine, the soluble sodium salt, used for tracing water flow and ocean dye markers). Is there an expanding wave of excitation? (Extracting a fluorescent highlighter marker with water will do it.)
What happens with air bubbles is called, “cavitation” it is caused by the rapid movement of the metal when it explodes. It is what causes the sound propellers make and it reduces their efficiency. Very big deal with submarines and why when a modern sub is out of the water, that part is covered up.
Great video. Cavitation bubbles are so weird and cool. I hope Anni is ok. I send you both hugs 💜💜💜
some time ago, I read about fusion happening in heavy water, deuterated acetone, etc by crushing such cavities. sure, they were created by sound, but your method seems to be much more efficient in creating cavitation, and maybe it's even energy-positive (something fusion has just achieved once in the NIF). might be interesting to explore. the NIF uses a massive amount of high energy lasers, being beaten by "some guy from finland with his hydraulic press" would be fascinating.
the problem is, that these cavities are created directly between the liquid and the tool as a result of a sudden release of mechanical stress in solid materials. i doubt that NIF would want any hard metallic parts anywhere close to a fusion reaction, no matter how weak. lasers are a way how to suspend such a cavity without physical contact.
You guys never disappoint
7:10 Since you’re in the mood for crushing sockets, you should crush a 10mm socket. Then again, that might explain why we can never find one when we need one.
Gremlins steal them.
Don’t know why you can’t find any 10mm sockets I’ve got dozens of them
Awesome video! I bet there is cavitation on the tool parts is because of the shockwave traveling through the metal of the tool when the balls break. I think we need more!!!
High pressure shockwave is followed by low pressure wave, allowing dissolved gases to come out of the water?
Could try sealing the chamber and applying vacuum to try to pull out the dissolved gases, or try to find an oil that is conducive to filming? Maybe then you'd be more likely to see cavitation?
EDIT: Wouldn't need a vacuum during the crush, just for some time beforehand.
Thanks Lauri, great video. 👍
Very cool to see the back and forth cavitation pulses! It would be interesting to compare the same inward-outward pulses but when you are using a more 'suited' anvil (more cone shaped, I imagine) instead of the rather large 2 parallel planes the ball bearing ball is sitting against now.
But awesomeness all the same! Thanks for these videos, I really enjoy them.
Channel keeps getting more interesting as it goes on
The socket was really interesting, the small amount of air trapped inside created a vacuum that sucked everything back inside almost like the camera footage went into in reverse.
This reminds me of the bubbles you see in the trick when you fill a beer bottle and leave a small air gap at the top. You then smack the bottle rim with the palm of your hand to blast the bottle base off and it's in the seconds before the bottle base flies off, on a slow mo camera, you can see captivation bubbles appear & disappear and boom the bottle loses its base & it's contents. It might be an easier experiment to perform in a tank and with thick rubber gloves but I have to add this - do no try this at home, as I'm not getting the blame for shards of glass in your hand 😉
This is similar to one of those glass tubes filled with distilled water that get sealed with 0 water inside them. When you wiggle them they make knocking sounds like there's beads inside, but it's actually caused by cavitation of water, since there's no air to act as a spring to squish it into obedience. Thunderf00t showed one of those off.
I believe the air bubble formation is a similar affect to the mantis shrimp when it punches. It also forms an air bubble under water due to its extreme power. "Cavitation is when low pressure in a liquid produces a bubble that rapidly collapses, and heats up to 20,000 Kelvin - hotter than the sun's surface."
We can learn a lot from these experiments.
It's fascinating how the cavitation bubbles form but then collapse back in on themselves when the vacuum is filled. This was most visible with the second socket.
That cavitation bubble on the single ball took my breath away!
This is one of the most interesting videos for a lot of time at CZcams !
How do you think all this gonna look if you using liquid with more different viscosity ?
Next time you want to record cavitation bubbles, for the ball bearing you could set the focus closer, around the edge of the tool rather than the ball bearing itself. Larger objects like the socket was a bit closer to the subject.
It looks like it’s all about the bit that moves fastest during the failure. It’s always there that the cavitation bubble forms, which makes sense
I really appreciate that you guys actually read comments, and take suggestions. It makes me really happy, also we're probably looking incredibly high pressure waves through the water... almost like it moves the water so fast that it creates an empty space with a vacuum inside
That’s exactly what cavitation is. You get temporary voids that collapse a split second later.
It's neat how the ball steel becomes so finely divided that it spontaneously combusts. When making a fire with Flint and steel, it's really fine particles of iron causing the spark.
The “flint” is usually ferrocerium alloy.
that cavitation effect is amazing
You got it “bujoiiing” is the correct technical term for exactly that
Great video. Those ball bearings really explode with force.
I’m sure you won’t see this but you mentioned in the video you have issues focusing the high speed on such small areas, get a laser pointer and shine it on the area you want to focus on the auto focus will get it perfect or if you are using manual focus it helps a bunch!
Nice. I think the direction of the cavitation bubbles in the last one might have more to do with the speed of sound in the material
Absolutely fascinating
Would there still be cavitation bubbles if you would spray/wash/brush away the remainder of air bubbles before doing the crushing?
Hollow tubes with their ends above the water. The air gap could lead to interesting cavitation and if you add different colors to each tube maybe colored cavitation?
How well do you think the mechanism for a blender would work, drilled and glued into the bottom of a tank? Could overdrive it with some stupid-fast motor, then use it for actual mixing when you're done making pretty bubbles and whirlpools.
You should try some of these again but with minimal lighting as the explosion is so violent there would probably be a nice light show. Could sort of see it with some of the bubble flashing on the last one
Phantom camera, big press and big ball bearing would be the dream!
Very cool. Nice slow motion video!
A prime reason for proper torque on roller bearings. This should be a part of auto tech 101
Cavitation bubbles are awesome. Try to generate them using standing sound waves.
I really enjoy your videos there very interesting thank you
Two ideas - 1) put a piece of metal mesh close around the ball bearing, formed into a cylinder and rivetted shut. Will the bubbles form inside or outside?
2) Put your gopro in a waterproof case under the water? Would the shock break the case? Perhaps try it with an empty case first.
3) An Infra-red camera showing where the heat is (good excuse for a new toy too)
It looks like the force of the item breaking apart is creating a vacuum for a split second and the bubbles are being created by the sudden low pressure around the water as the vacuum collapses. You can even see what looks like a rebound on the last item destroyed after the first void collapses.
I like how the light reflects off of the ball bearing, creating two bright light spots, so that it looks like 2 bright eyes on a little face on the ball bearing😀
Hell yes, I suggested this idea earlier in a comment and now its happening!
You read the comments 😁 nice to see you tried this, thank you.
I was surprised not to see more cavitation bubbles, considering the initial speed at the point of destruction 🤔
5:02 The way he says "again😈" 🤣
A way to create cavitation might be a setup that contains a flexible bar that is depressed by the press tool and then released, similar to the sear on a firearm's trigger that releases the hammer.
It's the vibration of the socket as it snaps that excites the cavitation effect.
Very cool and YES! very interesting as to what causes the bubbles... Super heating from the sudden pressure on the metal? How about adding zooming in closer with higher resolution and perhaps adding some colouring for better contrast? Also - how would this look in a different liquid - for example oil?
Got to admit... that's cool as hell!
LOVE YOU GUYS!!! FROM THE US :))))
I love how the ball just spawns in
Could the cavitation be charged attracted to the metal being oppositely charged creating the result of the bubbles wrapping around the socket ?
I was hoping to see cavitation bubbles and I was happy to see that the results were mostly about cavitation bubbles.
The first crushing of the bearing ball was really interesting because it looked like the press surfaces had cavitation when the ball failed but that shouldn't make sense because sudden movement of press tools should cause high pressure, not low pressure. Is that some other known effect we were seeing there?
I think you should do more cavitation videos. Maybe something with explosives or bullets to have even longer cavitation trails?
there's so much space x coverage I thought your poster frame was the booster and rocket and new header tank. 😂😂😂
It looks like when the "explosion" happens, any surface which gets instantaneously moving very fast (but a very small distance) creates cavitation bubbles. It's every time the case of at least the above press tool, sometimes the bottom press tool and also the object being crushed.
I can't wait until the day we see Hydraulic Press Channel in space
My guess would be the cavitation around the press tools is almost instant because the pressure/shock wave is traveling faster than sound sound in the liquid. So the bubbles appear all around it at once because it’s delayed compared to the event.
Thanks for this video
I think the ring of cavitation bubbles is from the tool it self vibrating when the ball first breaks, it appears to happen along the whole surface simultaneously. Not spreading out from the ball.
I like this stuff. It’s really interesting .
