There should be a density of boat that is less dense than the super-critical phase, yet more dense than the gas phase. This boat should still float on the liquid, but when it turns super-critical, it would float on the whole super-critical fluid, rather than just the liquid alone.

The problem is finding a material that would have that low of density at that pressure. even the Styrofoam lost some of it's buoyancy due to being crushed. and Silicone arogel would fill up with liquid Co2 since that is how it's made. maybe coating the arogel would work, but it's going to shrink some.

@@LaserFur 'but it's going to shrink some.' Yep, something that would float on the combined phase and move up was the first thought. But most anything should crush or saturate, and then sink instead. But forget a solid object, find a different density liquid or gas that would have the correct properties. Should be able to find something that would work, and be a blob between them and then move up when it goes supercritical.

I know it's because of the camera's resolution but I could see the line quite clearly where as you couldn't and your shanking it continuously actually made the transition less amazing for the viewer in my opinion. I know why you were shaking it but I would love to see this again but left completely still. The high resolution video makes it much easier to see on screen than you could in person it seems.

This is very watchable now 🙏 I didn't realize how eyestrainy it was until i saw this version

Yeah, even with small motions of the eye staying focused on the "boat", the eye still has the motions to do

I do not understand why there was a need to shake the whole apparatus in the first place. If everything else stood still, the minute changes in the meniscus will automatically draw our eyes towards it. This is better versus shaking it where everything is in motion and we can't even focus on the important thing (ie the meniscus).

i like your funny words, magic man.

Thanks for showing how matter behaves under extreme conditions😊

Pretty sure if I’m on a lake that suddenly went super critical that I’d already be dead from the conditions that brought about a super critical lake That’s definitely a “You died” type experience right there

This video is so incredibly much better. Uploading it again was a great idea

Thank you for the stabilized version. This is much more comfortable to watch.

You should definitely reshoot it without the shaking and with some of the suggestions about dye coloring and background patterns and stuff

This reminds me about Applied Science and his video from 12 years ago --> A close look at supercritical carbon dioxide CO2.

what if you add dye to the liquid? what will it look like because now everything is transparent.

@vincenttrigg4521

Most dyes that we use are used in water or alcohol so making those supercritical are a lot harder to achieve. I'm personally unsure how the pigments would react on their own. Maybe they would stain the vessel due to the pressures implemented.

The squished half-sphere of styrofoam totally looks like a brain! 😍

I have been watching you since I was a kid. Keep up the good work. Love! ❤

One of your many good ones. Thank you 🌀

That is the most amazing video I watched. Thanks for the efforts making and sharing it.

Glad you posted this version

The motion stabilization makes a surprisingly large difference, thanks!

"so next time you're on a lake that goes super critical, be sure to get to shore quickly" - GOAT advice 😊

Thank you for this. I needed to see this.

Great experiment, never thought that it could be done in that way.

A nice alternate view. Thank you for showing the motion stabilized version

It is absolutely amazing to see the "boat" slowly sinking, indicating that the liquid becomes LESS DENSE, which is something a normal liquid absolutely cannot do, which in turn indicates that the liquid is no longer normal. It's supercritical - a gas-like liquid, or a liquid-like gas. It's an effing fourth state of matter aggregate! I say plasma is demoted to the fifth place.

Thank you for finding a question and answer to something I may have never has the imagination to ask and try to answer

loving the new look

you learn something new everyday

Man - EXCELLENT, BRILLIANT -- THANKS!

What an awesome experiment. I love your creativity. BTW everything went exactly as I expected.

I will definitely remember this for the next time Lake Superior goes supercritical.

Poor little foam. It suffered so much for you.

I think you should have done this with something that uses displacement to float instead of Styrofoam which is just buoyant, because that's how an actual boat works

@godslayer9000

22 күн бұрын

Everything that floats is using what you're calling displacement. Styrofoam is mostly air, which is why it's good at floating no matter what kind of shape you make out of it. Boats are like if you took a huge block of styrofoam but all the foam was compressed into a "boat shape" and all the microscopic air pockets were consolidated to be the place where you'd sit in a boat. Styrofoam was arguably the better choice here as action lab could shake it as much he wanted and not risk tipping the "boat" over, ruining the experiment. I imagine normal boat would've behaved exactly the same as the styrofoam piece except maybe up until the supercritical fluid was cooled back down to a normal fluid, as it could have filled the boat with a lot of liquid and sunk it.

Mesmerizing !

Cool experiment

What a beautiful sight

Action Lab is the hero we never knew we needed 👌🏼

Thank you for this... I was going crazy

that is MUCH better. lesson learned for future videos. avoid rapid/large movements with macro shots XD

impressive!

super-fluids are amazing.

Weird short, cool video

I learned about supercritical fluids in Walt Brown's book "In The Beginning". Strange things happens in a supercritical state.

Amazing

Started off pretty cool until things got heated.. Still, it's a solid demo overall. Or was it liquid? Gas? Congrats on inventing the world's first supercritical Sterling engine. Hope to see this carbon capture wonder engine in the next clip. Keep it up!

Thats much better :D I mean I saw the first video to the end, so it's not necessary for me to look it again. xD But I let a like and a comment here ^^

Styrofoam is porous - and surface tension will help to keep it from soaking up liquid CO2. Try this again with a solid plastic cube to eliminate porosity questions (one with density near that of sea-water should yield similar results)

Are you a liquid because you were a solid that gained latent heat or are you a liquid because you were a gas that cooled? Nah, i am Supercritical.

Nice Lightner

The styrofoam crushes because of increased pressure. That seems to me another factor; it’s specific gravity rises so it sinks a bit even in the liquid CO2.

I wonder if that happens sometimes in ice giants. Do they have enough gravitational pull to create these pressures? Would certainly be a cool premise for a sci-fi story. Trying to rescue yourself while the liquid your ship floats on just disappears.

Polystyrene is foamed by use of water vapor flash evaporated. Which means carbon dioxide vapor can enter which is probably why it won't float as well.

You are great

As cool as this video is, the squeaky table drives me insane

Looks like a big tardigrade dk why 😭

omg you uploaded a non short to your shorts channel, now you will have to rename it to Action lab: action-ier

@frogz

23 күн бұрын

also, you probably diffused the air out of the styrofoam and it is full of co2 at that point, i suspect it would do the same thing if you put it in water with high pressure for a while until all of the air contained was crushed, if you were to fully diffuse co2 into the styrofoam by soaking it beforehand for a while at higher pressure you might be able to keep the pressure in the "boat" higher than the surrounding supercritical fluid...but... that is just a guess and i am basing it on my own knowledge and no actual research

😂 I can't believe you did this!

That thing floating in the beginning looks like the air bison Appa from Avatar 😂

Awesome :D

Vodka and Scotch are MY supercritical fluids 🫡

Yes speciallly the tip at the end

I want to build one of these just to have a mini rain shower on my desk. Wonder if you built a tall enough one if you could make mini snow.

Either float to top or sink depending on boat density

Much better.

I'm just glad he cut his hair finally...😊

Surprising how the styrofoam could resist to more than 1000 PSI without collapsing.

Could you do this again but with some fine neutrally-buoyant glitter sprinkled in there to help visualize the flow of material? Or would that risk damaging the chamber too much?

I know how that piece of styrofoam feels

Still a bit shaky but it’s definitely better

Where can I find such a pressure vessel?

8:43 So if the average density of the supercritical mixture is greater than the average density of the boat then would it float to the top? Hypothetically if you used a different substance that was less dense than styrofoam, and it is less dense to the average, supercritical density

Cool

Even with it stabilised the constant shaking annoyed the heck out of me.

Really think about this video, internet. There's something hidden here

Can you do it with more dry ice and less air above it, I think boat might float in this case

Yeah it can but it comes out feeling really bad about itself.

For me it was surprising that the styrophoam has bigger density than the supercritical CO2..

Is Jupiter a super critical atmosphere? I heard somewhere if we were to have a suit that could keep us safe and we drop into jupiter we would be in a state thats not quite liquid but not quite gas.

If you're on a lake and it turns critical be sure to get to the shores quickly 8:53 for more practical tips like this...

Put a bug in there for purposes of science

cool

Wow, it's almost like, you could have figured this out by just remembering what density is :D

I would have used a torque wrench to ensure equal bolt tension.

What would happen to the density if you had filled the chamber with liquid to 95% full and then heated it to supercritical? Would the boat float? What would the pressure be?

Ya know how a feather and a rock fall at the same rate in a vacuum? Would the same thing happen in this environment?

Can anyone give me the link to buy this vessel, it would be very helpful

What I've actually learned from this video is that supercriticality is not anything too different from other states Its normal

So is it just that we cannot see the line anymore or is it the liquid and gas becoming one because of the high pressure?

If that aint magic I don't know what is.

still shaking it!!!!!!!!!!!!!!!

What about the air inside the styrofoam compressing under the pressure, not being buoyant anymore? I'm confused...

What Would Happen If You Release The Pressure When Its Super Critical?
