I already did some planning for the watermelon. Seems that it's going to be about 65 bars at room temperature with co2 there. Maybe 3-4 days should be enough to make it saturate and then quick decrompession for explody results :D I try to get it out next week! Also just realised that I have the wrong intro :D I was planning to release this on HPC first but I have too long line of ideas there :D
It probably did not cause any spectacular effects because the meat has no blood circulation. Also the longs have a lot of surface area to dissolve gasses in the blood and from their into the surrounding tissue. I don't know how you could replicate that.
Mixing some gelatin and letting it set in the pressurized chamber could be interesting. The more solid-structure of gelatin may allow the buildup of bubbles to be more visible as it would likely either 1. explode or 2. capture the gasses in bubbles internally which may then be visible by passing light through the decompressed gelatin edit: apparently someone wrote a paper covering this: "Quasistatic growth of bubbles in a gelatin gel under dissolved-gas supersaturation". my non scientific take away is that you'd want the gelatin solution to be as week as possible (as a stronger solution inhibits the growth of the bubbles) and you may need to add some energy to the system to trigger bubble formation
@ 9:33 you can see the puddle in the bottom starting to fizz and create very small bubbles. Maybe because of the greater surface area it absorbed a bit more gas.
Yes, it was very obvious in the pool along the tank bottom - probably as it had much move surface area and a small total volume, so could absorb a larger percentage of gas.
I think that shimmering was the beginning of a dimensional rift forming. It's lucky you didn't add any more pressure as the results would be unpredictable. You only got some strange acoustic effect, like from about 9:30 you could hear your past self talking about the experiment. 👀
Just got to the part where he mentions 125 stories in 30 seconds and all I can think of is "Um.... Meat shrapnel?" Going to be interesting to see if I'm right, but even if not it isn't a mess I would enjoy cleaning up. Edit: Welp. I was way off. No mess at all.
i appreciate the try. Even difficulty in re-producing the phenomenon, is good data produced, and i am still interested coz it gets people thinking on why it's hard to re-produce 👍
Just for information, bottled gases are notoriously wet, it's fine for a lot of industrial applications but not for specialist applications. Where I worked, to get dry nitrogen we used an evaporator and liquid nitrogen. Dry ice should give a good way of getting nice dry co2 :)
I wonder if you could make the world’s most carbonated soda in that pressure chamber - imagine if you could shove 60 bars of CO2 into a regular 1 liter bottle of coke and then poured a few mentos in it XD
At high pressure the gas is much 'thicker' and slight temperature or density variations refracts light quite noticeably, especially while mixing gasses(Nitrogen in air) there will be a lot of density variation until they mix thoroughly.
Actually, small air bubbles are perfectly safe in your veins. I've been on IV drips before where I've literally watched an air bubble flow through the line and into my arm. Of course with the myth of how little air it takes in your veins to kill you, this freaked me out. But the doctor reassured me it was a normal thing with IVs and perfectly safe. And I'm prefectly fine. Even though contents of the bag are vacuum sealed, when they connect the lines, a small amount of air gets in. It's no big deal. A 10cc syringe full of air on the other hand might be a different story.
The reason you can be killed by DCS (Decompression Sickness, aka the Bends) is because the Nitrogen bubbles that form in the blood stream obstructs circulation. A slab of meat with no blood flow is really non suitable human analog.
If you were to pull a vacuum on the water and meat then put the carbon dioxide gas connected to the inlet where the air goes in to relax the vacuum you might get a better reaction.
The meat would need to be in something alive and breathing to transfer the nitrogen lol. The only way the nitrogen is absorbed is because you breath it while diving and it is absorbed into your bloodstream by your lungs.
At 9:30 it may be tiny bubbles popping in the puddle of water at the bottom of pressure vessel (or it may be droplets, or something else? I'm not really sure here)
Chat gpt is wrong, each floor wouldn't be 500 meters... Honestly, don't trust it for math, it can't even do simple gear ratios A story is 10.82ft, x125 is 1352.5
Barely compressible liquid system, fine. Gas systems (even well outside the ideal gas approximation), with great caution mostly fine. Even when nothing safety-endangering happened, liquid-gas systems give me the irrational heebie-jeebies.
The word you were thinking where it appeared to be wavy is a "supercritical fluid." Blood contains the nitrogen. Meat is bled before being eaten or sold secondly that blood must be pumping to absorb the nitrogen.

In this video, Lauri Vuhonsilta wellcomes us to the wrong channel...
I didn't even realize that before publishing the video :D But what the hell same guy doing the video and same guys watching on both channels :D
@@Beyondthepress No sweat, mate. The odd brain fart every now and then just adds to the charm and character of the whole caper.
😂😂😂
I thought this was the Dropzone channel, yeah, but his accent is different
@@tomholroyd7519 That's the charm of the Finnish language, you pronounce words by the letter, and Lauri does that. I know, I'm from Finland myself.

1:00 There is water in the water that's why it's wet
That's why we come here, to learn profound things. 😁
But have we answered the age old question is water wet or does water make things wet?
🤯
The cross-contamination is disgusting! :D
If he's underwater, does he get wet?
Or does the water get him instead?
Nobody knows. Particle Man.
Na, water is made of gases only, so it can't be wet...
Looks like he’s setting up to do the most incredible dab hit 😂
there is 2 audio tracks playing towards the end of the video
@ 9:33 you can see the puddle in the bottom starting to fizz and create very small bubbles. Maybe because of the greater surface area it absorbed a bit more gas.
The nitrogen DID dissolve well in the water. It's not very clear, but the water was fizzing like pepsi max at least on the surface.
Not seeing it.
@@manuelh.4147 You can see it on the puddle in front of the cup
Yes, it was very obvious in the pool along the tank bottom - probably as it had much move surface area and a small total volume, so could absorb a larger percentage of gas.
Is that a bong on the table ?
lol nice bong
Fantastic video mate cheers !

"Nothing leaks. So that's nice."
My doctor said the same thing. 😉

Lauri I had a dream that you were a fireman in Oulu and were showing me around an abandoned industrial building. It was really weird.
What's with the sound from about 9:42 ? Did you hire a voice dubber or is it just an editing glitch ? 🙃
i appreciate the try. Even difficulty in re-producing the phenomenon, is good data produced, and i am still interested coz it gets people thinking on why it's hard to re-produce 👍

9:20 Lauri clone talking in the background.
Purge the air out prior to pressuring and pass nitrogen through the water to increase saturation.
yeah more bridge or railroad or tunnel will be amazing
What was up with the bong he had sitting out before he did the thing?
thank you for converting euro units into building stories but could you also describe pressure in SUVs next time?
I wonder if you could make the world’s most carbonated soda in that pressure chamber - imagine if you could shove 60 bars of CO2 into a regular 1 liter bottle of coke and then poured a few mentos in it XD
Such excitement I don't know if my heart can take this😢
I got an add for a beef roast with this viseo! 😂😂😂😂😂
My suspicion that the shimmering effect (5:12) is from the heat of the light.
At high pressure the gas is much 'thicker' and slight temperature or density variations refracts light quite noticeably, especially while mixing gasses(Nitrogen in air) there will be a lot of density variation until they mix thoroughly.
Yesssss let’s go beyond the press uploaded. I can’t wait for more explosions videos!

Nitrogen gas is supposed to be “resistant*” to expanding with heat, what we see shimmering is gas heated by the bright lights.
The reason you can be killed by DCS (Decompression Sickness, aka the Bends) is because the Nitrogen bubbles that form in the blood stream obstructs circulation. A slab of meat with no blood flow is really non suitable human analog.
Damn, I was hoping the meat would do an impression of Arnold in Total Recall 🙂
“Hoo-draulic”
“Presss-ooo-reh chamberrr”
😂 God bless you ☦️
You should do it with sealed cans, fizzy juice, soup, fruit or other canned or bottled goodies.
They'll be explosive! 😆 🤣 😂
If you were to pull a vacuum on the water and meat then put the carbon dioxide gas connected to the inlet where the air goes in to relax the vacuum you might get a better reaction.
As a machinist
I want mote video of your job
You are a model for me
Thank you
Would be interesting to see if hornets or wasps would survive coming instantly up from 500 meters.
I think you should try using a marinade on the meat instead of water and then cooking it. Tell us if it gets infused with flavor! 😁
Bubbles in the muscles and flesh are only painful. Bubbles in the heart and the brain can be deadly.
The water fogged up before the large bubbles appeared. That might have been lots of small bubbles.
The "bubbles" are always there. They are likely drops on the glass
I wonder if stirring would help the nitrogen get into the solution there
This was like watching paint dry
I would like to see this experiment done with animal blood. Possible that there is a reaction from the red blood cells.
Isn’t it supposed to be NO2 nitrogen dioxide not just pure nitrogen gas?
This one a bit dark after the uh.. titan submersible incident
10:40 that's why freedivers don't get the bends...
I bet this would work great for a fast marinade 😂🥰
would bubbling the gas through the water as you added it increase the amount dissolved creating a more lung like example.
Imagine if Lauri had a particle accelerator...
The meat would need to be in something alive and breathing to transfer the nitrogen lol. The only way the nitrogen is absorbed is because you breath it while diving and it is absorbed into your bloodstream by your lungs.
You probably should have thoroughly flushed the air out of the chamber with dry nitrogen before pressurizing. Your nitrogen supply IS dry, right?
You can see his nitrogen setup on HPC's airlock video, he's tried flushing with dry nitrogen from a bottle, but he's still getting mist
@@Ultimaximus Hmm. I guess the only other choice for a moisture source is the "test subjects" themselves.
did the nitrogen go super critical?
I have no idea what's happening there :D
It goes supercritical at -147 C and 33 atmospheres, so room temperature & 50 atm is definitely it.
At 9:30 it may be tiny bubbles popping in the puddle of water at the bottom of pressure vessel (or it may be droplets, or something else? I'm not really sure here)
When are you going to do more explosion videos? I missed that already😢
We have filmed already punch of them, I release next in 2 weeks!
@ thanks
He tried, but the piece of meat refused to explode.
Does Nitrogen BBQ Beef taste different?
Tryb using fat or lard. Solubility of CO2 in fats might be higher than in water.
Does 'Teisko' mean 'I forgot to turn the microphone on' in Finnish? 😊
You have to understand what decompression sickness is
Chat gpt is wrong, each floor wouldn't be 500 meters... Honestly, don't trust it for math, it can't even do simple gear ratios

There's Water in the WATER? What kind of dirty-ass cross-contamination is this?
I didn't understand shit because you didn't say how many elephants were sitting on my face.
9:30 i should call her...
In today's video, Lauri forgets to turn on his mic...

Put a *small* chunk of sodium in a glass jar, crush the jar to see what happens to the sodium.
