Paper + Liquid Nitrogen + 300 Ton Press = HUGE EXPLOSION

[@test-rj2vl]

I think you should have kept papers in liquid nitrogen for longer time. Like the A4 papers were still freely bending when you put them in. You could try to cool them for few hours at minimum or even more to make them so that they don't bend when you hold them from 1 corner.

[@soundspark]

It must cost a huge amount to ship outside of Finland.

[@dannydaw59]

Have you considered putting clear plexiglass in front of the cameras? There might be glare, but tilt the glass till no reflection comes back to the lens.

[@code187jwt]

Now you need a dB meter to measure the difference in explosions 😂

[@Harald.]

@@dannydaw59 The glass lens that broke, is actually just protection for the real lenses. The camera body is tough as hell. Nothing to worry about.

[@ForumArcade]

I love watching the liquid emerge from the paper as it compresses.

[@HydraulicPressChannel]

It was super interesting. Is it wet or not? :D Looks dry but lot of liquid comes out

[@ilickbatteries35]

I don't know why, but I definitely didn't expect the books to be LiquidN absorbent

[@gth042]

Pretty small molecule, low surface tension, only that I've seen it does it start to make sense though.

[@Krecikdwamiljony]

Quite surreal. Also time to prove press drying wet clothes is better than tumble drying?

I actually appreciated your sponsor clip. It was not your unusual sponsorship clip, but more of the engineering side of the channel. Well done.

[@blackwater2192]

I appreciate the safety warning at the beginning. Too many people fail to realize the danger of liquid nitrogen or dry ice. Not realizing that it quickly wants to become a gas again. It will dilute the oxygen levels if you're in an poorly ventilated room and can kill before you know what's happening. Safety First!

[@DougPaulley]

I find it tasty and refreshing when I drink it.

[@user-cb3qr9dt2k]

Air is already 70% nitrogen, it would an awful lot of it before you would ever need to worry about it plus it's inert. CO2 on the other hand is more dangerous as it can be absorbed back into the blood as its binding to hemoglobin is only slightly lower than oxygen.

[@vincenttrigg4521]

​@@user-cb3qr9dt2kyeah but there's a lot being used here. Liquid nitrogen is very condensed so evaporating into a gas takes up more area and thus less air to breathe in. The biggest problem I'd think is you lose too much oxygen to function and then be unable to escape

[@MarcoTedaldi]

​@@vincenttrigg4521one liter of LN2 makes about 700l (npt 1000l) of gas. The bunker has a volume of about 40m³ I guess. So 1l of LN2 will get N2 content up maybe 2.5%. From 78% to 80.5%. And 1l LN2 is a lot. What we've seen coming out of the books was maybe 0.2l... Nope, not an issue but better save than sorry!

[@Harald.]

@@MarcoTedaldi I disagree. When evaporating, you have close to 100 % nitrogen in the air near by. Nitrogen is lighter than air, so until blended into the air, the concentration of nitrogen will be higher, further up in the room. You would not die from lack of oxygen in that room, but it can make you do stupid and dangerous decisions.

[@NoobixCube]

I don't normally use the comment section to spruik a product, but that smashed lens filter makes this relevant. OKKO's "pro" lens filters have a lifetime warranty, even against breakages. Disclosure: I work for their distributor in Australia, in the support department, so I'm a few steps removed from having any real interest. Just thought I'd point out a thing I know has the kind of warranty you need on this channel.

I wonder if it would be any different if one soaked the paper in regular water, gave it light squeeze to remove excess water and the froze it all over night in a freezer. Fun video and the video from the Go-pro that went spinning after the 3 books was great XD

I think from the Acoustics in the Main Shop with the old press the explosions seemed louder. But the results are completely different visually. The new press is much more destructive. And finally with the Liquid Nitrogen we heard some epic explosions,.

[@dennislindqvist1265]

Maybe one should build a microphone that can withstand the pressure inside the bunker? Probably doable but not much of the sound would remain.🤔

[@epajarjestelmainsinoori9037]

Anyone who has chopped frozen wood and non-frozen can appreciate and fully support your theory for the next video. Frozen wood splits all the way through easier as it cannot flex and the axe impact is transmitted the full length of the piece. I would expect bigger initial resistance and sudden failure (we all know what this means in Lauri's vocabulary)

[@karenglenn6707]

I’m an Aussie and was the wood chopper in our household as I love it. I never knew that as wood doesn’t really freeze here and I’ve never seen frozen wood. Thank you for that, that’s interesting 👍

[@epajarjestelmainsinoori9037]

@@karenglenn6707 Here in Finland we always try to chop the difficult pieces frozen. For easy stuff it doesn't really make a diffence. But for something like spruces which are a relatively soft wood but highly flexible long fibers, and nasty to chop when they are big, it makes a huge difference. And ofcourse it needs to be fresh or wet to be frozen good. Not worth the trouble of stacking in a freezer in your part of world though.

[@Sk1m_Beeble]

​@@karenglenn6707yeah not really a problem we tend to face here lol

I think the word you're looking for is "saturated". You're correct that "wet" suggests water or another actually stable liquid.

6:59 The book isn't actually "wet" in the usual sense, even though it may look like it. When you soak a book in liquid nitrogen and then press it, the liquid nitrogen can appear to flow away from the book, resembling water. This occurs because the rapid phase change from liquid nitrogen to gas creates a brief liquid layer that looks like water, but it's actually cryogenic nitrogen. While this liquid may visually mimic water, the book itself does not become "wet" in the traditional sense because nitrogen does not have the same properties as water regarding adhesion and wetness. As the liquid nitrogen evaporates almost instantly upon contact with room temperature surfaces, the moisture-like appearance is primarily due to the nitrogen transitioning from liquid to gas. The book may feel cold and frosty, but it won’t have water on it unless there’s condensation from the surrounding air, which could freeze briefly but will likely evaporate quickly.

[@NoobixCube]

Even if it isn't "wet" in the traditional sense, it's still interesting that the books seemed to carry so much liquid Nitrogen in them. I thought the books would just get cold, and any moisture would be just water condensation from the air. I was also really surprised, with the postit notes, to see it clearly flowing out via the edges and not the corners. That's the kind of thing that, if you saw it in a movie, most people would think it was an animation mistake.

[@haileymccurry3756]

i don't think anyone was saying the book was literally soaked in water, my man. People are saying 'oh wow the nitrogen looks like water, how funny'

[@NoobixCube]

@@haileymccurry3756 I think his use of the word "wet" here isn't at people saying "this is water", but it's in the very technical chemical sense of the word "wet". Of course, water is not actually very wet at all (something chemistry teachers love to say). Surface tension stops it from wetting things efficiently.

[@aexetanius]

@@haileymccurry3756 He asked whether the book was considered "wet" when it's not water, and I replied.

[@ni_wink84]

Paper isn’t without water, it isn’t anhydrous being wood pulp it absorbs moisture and needs more time for the nitrogen to freeze the water stored in the cells of the wood, because of this the “water” stored in the cellulose of the wood fiber causes the nitrogen to stay “liquid” as it bonds to the hydrogen in the water molecules, as it is pressed out just like any gas under pressure, it changes state, when the books are pressed the nitrogen again changes state being surrounded by hydrogen and molecularly being forced into a smaller space where it again is restricted to its escape, that’s why it is off gassing with no pressure and looks to be “liquid” being pressed, the molecules are being forced to tightly pack with water molecules and the water is displacing the heat of compression, “latent heat of vaporization” the pressure is causing the nitrogen to return back to a liquid state then immediately boils off after being pressed from the paper. Same reason propane is a vapor until it’s compressed or any HVAC equipment in operation sees a gas go from gaseous to liquid in a sealed system PRESSURE!
