Thanks to my friend Tami for explaining the weird results for me. If you are interested on hardening and heat treatment of huge steel parts go check out this video on Beyond the Press kzfaq.info/get/bejne/ldJ9qpthuJzQlJc.html There Tami shows their heat treatment facility at ATA Gears.

I've heard of people cooling their balls with ice packs to improve performance, but using liquid nitrogen seems a bit hardcore to me.

Cryogenically treating steel can make it surprisingly strong. It's used to heat treat drill bits sometimes

I never thought I'd see the day where anything actually STOPPED the hydraulic press at maximum. Wow!

It would be cool to see a slo mo guys team up vid

I'm sure that you and the Slow Mo Guys would have a great time together no matter what crazy experiments you decided to do! (But I'm sure they'd prefer to visit Finland in summer :D )

That 320000fps shot at the end is absolutely amazing. You see visualizations of high speed explosions and they obviously don't do it justice. The way the pulverized material hangs in the air at specific angles and in specific color ranges is really cool.

So great to see Anni being involved in vids again. Even just having her reactions on audio really brightens the mood of your vids.

There are few visuals more satisfying to me than watching scale flake off of hot steel under pressure.

2:20 Sounds like an accent an American actor tries to make to sound foreign. 😂

these videos are getting more and more crazy, keep it up !

I love your videos, but when Anni is there providing reactions, it just kicks them up a notch. 😂

Hydraulic Press Channel has the strongest balls of steel!

WHAT THA hELL 2:08 I love the finns accent to funny people! from sweden!

Hi Anni! Was cool to see the heat transferring from the pressure points down to the middle of the ball

Making the balls colder increases their brittleness, but what that really means is its hardness goes way up, but their ability to absorb shock goes way down. so it would be easier to throw a frozen ball bearing at the ground to break it than to just apply force to break it.

High quality content. Loved the slo-mo. Glad to see Anni there. Cheers.

What a wonderful example of how pressure creates heat , as you can clearly see the transition as you work the press.

As an engineer student, it is cool to see the theory in practice

Wow! Your filming setup is so much better these days!

Freeze frame at 0:38 is a great thumbnail! Also nice to see Anni again :D

"Big ass bearing balls" 😂. Idk why that caught me off guard, but I literally laughed out loud. That's funny af, thanks for that

The faster cameras are nice, but we come here because of you and your ideas.

yaaay, Anni's back 🙌

This has likely been said already, but I’m almost certain the ball bearing from the previous video didn’t get red hot at all. What you saw was a frame where the sparks blurred as they shot across the flat surfaces of the press tools and the rounded surface of the bearing reflected the blurred sparks making it appear as if the bearing was hot.

I might be high on sugar but when I hear that slomo blast sound 0:53 and see those lamps falling inside, it cracks me up 😂🤣☠ thank you for the entertainment 🖤

Thank you for showing the super slow motion versions!

That Slo-mo was gorgeous... 😍

3:30 Unexpected Cosmo and Wanda.

I like the videos when Lauri makes things "more explody."😁 Prrritti Guud. 👍

my theory is the little dent that formed from destroying previous balls create a "holding" cushion that makes the cold ball harder to crush. pressure with less surface create more penetration, the sunken dent create more surface that caused the ball become harder to crush

Thank you for showing up Anni, you make every video better, it's more like a family environment..

I would love to see a collab between your channel and Slow-Mo-Guys. that would be a greatly amusing and maybe even educational episode. Great content as usual either way.

The cryogenically hardened ball bearing was intense. Is this the first time the all-powerful Hydraulic Press has been defeated?

It's my first time I watched your video 🤣 you sound like retired Mario by the respect man keep it up

I absolutely love this channel. Thank you for your hard work and dedication to showing us your fantastic videos!

Just wanna say the last one in slowmo was so beautiful. Good job

The way that everything jumps, falls apart and gets absolutely destroyed around the press in every video is hilarious 😅

Great video Lauri and Ani. Thank you.

The red hot ceramic ball was probably the most dangerous piece you ever tried to crush... this could've gone really wrong! 😅 /edit: I probably got that wrong. Maybe the ceramic ball wasn't hot.

You heard your community and showed us a (past) video with real slow mo. Thank you :)

The cams are a lot, so undersood, but the fact that the small bearing just vaporized is insane. Love it as always!!!!

I have been watching your videos for about a year and got super hyped as soon as I saw the Phantom camera at the end. Since 2013 I've been a big fan of The Slow Mo Guys and they are pretty much half of my inspiration and smarts for cinematography. One of my favorite things about your channel is the amazing camera quality that each and every video delivers. Image sensor size and dynamic range often matters more than resolution. The only thing better than the HPC is with the shenanigans of Gav & Dan. Would be a dream come true if you guys collaborated.

I just want to say I'm glad to see more original content from you recently. The stream of compilation videos just doesn't engage me at all, the part I like watching for is hearing what you're doing, why, and what your expectations are. Explosions are just a bonus, I'd watch without them lol

Excited for spess-ee-all guest!

I love his temperature messurement skills; »It's cold, alright!?« 🤣👍

Thank you for getting that camera for this video! The footage was absolutely incredible!!

I say your high speed cameras are good enough. I just appreciate your content regardless.

This channel has always been Awesome!!!! You guys are cool cats!!

Anni is back! Haven't heard her laughter in the last few videos I watched.

I love the high speed shots

Really miss the crushing of really dangerous clay items at the end of each video.

Nice seeing Anni back again

Ball bearing crushing is my favorite thing so far.

Seeing your new cameras reminded me of my max stats in the Hydraulic Press mobile game lol.

At least it’s comforting to know Dracula picked up a less violent hobby.

The colored nails of your wife are very very nice

Have you ever tried freezing the tools? Like, the base plate and the crushing part??

18K views + in one hour. I work with steel, and to see what loading this stuff can handle is always amazing. You have a great channel, and all the hard work that goes into all this is very much appreciated . I also replay the exploding bits. What this shows us is how the material is held together atomically. And the energy that is released when subject to force loading. I came across an interesting fact the other day. Each atom in a atomic nucleus is held together with a force of 20 lbs. So how many atoms released their 20 lbs at 7:53? Another fact I came across was that you could line up 11,000,000 atoms across the point on a pin. So the energy released here is enormous. Kind regards, and greetings from Africa.

This channel takes the theme of Bad idea to do with heavy machinery and Hold my Beer , to the next level now with Science, Haha. I luv hearing the guy's Finnish accent , and when things Explode, the reactions are Priceless ! Slow Mo shots are really cool to see , Pun intended.

"Vat 'de' Hell" is so freaking cool :D LOL nice catchphrase

"Vut da hill!" You cryo treated the steel. XD

Congratulations on discovering the power of cryo-tempered steel.

I now hypothesize that our understanding of the universe’s Big Bang is nothing but a ball bearing being smushed

0:48 that FUCKING SCARED THE HOLY SHIT OUT OF ME.. JESUS

"OK it's a bit harder......... (presses to max)..... VAT DA HELL!!!!!!!!" 🤣🤣🤣🤣🤣

A colab with the slow mo guys would be so epic!!!!

The slow-mo of the BB exploding looks exactly like the Death Star explosion.

Fantastic video, always love watching the press squish things.

A great demonstration of fine particles of iron being pyrophoric.

This guy's quite the ball buster

Chrome Alloy Steel Balls, the most common bearing alloy, are manufactured from steel of the hardening type AISI E-52100. 52100 is a relatively simple steel with 1% carbon and 1.5% chromium, and small amounts of Mn and Si. In use since 1905.

Can we get thermal imaging while pressing? That would be helpful with slow motion and doing calculations on different materials. Awesome Videos as ALWAYS!

Slow motion was Like a star collapsing on itself an going super nova. You created your own Big Bang

Great efforts, thx!

The slow motion is awesome, but don’t go into debt over it.

Liked and subscribed because I appreciate the slow Mo, awesome to see the heat when the explosion happens. Would love a video with the press channel and slow Mo Guys, dan and gav with you would be an amazing colab if you did some awesome videos like the paper or cards, ball bearings or any other interesting presses

It seems like KZfaq unsubscribed me from you. I was wondering why I didn't get any notifications. Glad to see that you guys are doing good! I have to check beyond the press as well.

i think the balls dont explode as easily at higher force, because as the force increases, the ball is making bigger dent in the tool, however bigger dent means bigger area and the stress is distributed more evenly on the ball. Harder tool would definitely make it easier to crush the balls. Making it all out of very strong steel might be expensive, so i suggest using only metal plate at the end of the tool

"some big ass bearing balls" im dying

Omg I'd love to see a Hydraulic Press Channel and Slowmo Guys collab!!! 🤩

Every time you explode a ball bearing with intense pressure, you create a tiny universe.

That slo mo footage was great!!! Def want to see more with that.

Definitely deadly but a hell of a lot of fun!

Ah, a ball bearing video. Must click.

I love when he says "OK!!!"

Talk about a ball buster…I regret nothing

Nice to see Anni again!!! Hugs

Are they back together? I had thought they were having issues. It's so nice to hear her laugh again.

the cryogenic hardening made it waaay stronger

You got nearly 3 1/2 million subscribers. We cant see how you dont already have a sponsor. Especially when you even had a couple million subscribers for at least the past 2-3 years

You have got to collab with the slowmo guys for one of such episodes.

The First one is like a fragmentation granade lol

Let's take a moment for the balls that were sacrificed for a Nobel purpose

Amazing, and yes many steel alloys increase strength when at lowe temperature.

Damn 130tons and that ball laughed in your face🤯

The return of the Stunt GoPro 📹🤓

I happy with what you do and have no complaints

I'm surprised Hollywood hasn't called you to render some cool explosions for them.

It would be absolutely awesome if the Slo-Mo guys paid you a visit. You share a lot of the same audience.
