For those who didn't like the shaking, I motion stabilized the entire video and posted it on my second channel. Here you go! https://youtu.be/acFkZiELN2g. Sorry for shaking it so much! I thought one of the most interesting things is watching how the liquid waves change. And also when the meniscus is almost gone, you can’t really see anything unless it’s moving. But point taken if I ever do this again, I will do less shakes, lol.

"scientist shakes a bomb for 9 minutes"

Buddy I think I've got bigger problems if I'm on a lake thats going supercritical
-
"I'm kinda nervous about using this much pressure" proceeds to shake the apparatus over and over. :D
-
Good to know I'm not the only one who couldn't handle the shaking.
-
Everyone is supercritical about the shaking.
-
My boss: "This report is super critical." Me: "Ah! So much pressure!"
-
I only thing I thought during this entire video was: "STOP SHAKING THE DAMN THING!".
-
A missing observation here is that the styrofoam got absolutely crushed. While it's in there you can tell the surface that was mostly smooth at the beginning is dimpled inward significantly. But then at the end 7:51 when he's handling it, you can see that the former half sphere is now a bowl. Styrofoam is normally less than 100 g/L density, so for it to sink in a 400 g/L fluid means that it must be squished to less than a quarter of its original volume.

That's the coolest demonstration of a supercritical fluid I've seen. Kudos
-
I just had a job interview for a company that uses supercritical CO2 as a solvent in industrial processes, I wish I had seen this video before my interview, very cool to actually see the phase transitions! Note that both liquid and supercritical CO2 are compressible, so those density figures are pressure and temperature dependent.

The sound of that shaking table was painful.
-
the shaking wouldnt be as bad if you either stabilized the footage to the tank, or mounted the camera directly on it, so we just see the liquid moving, and not the whole tank. BUT i didnt mind it that much and it was a very interesting demonstration!

3:14 MY GOD MAN STOP SHAKING THE THING!!!
-
Super cool idea, but I need to criticise some things: - you covered the thing with your hand at the beginning when releasing the pressure; - stop shaking it please; - the word you're looking for is "interface"; the meniscus is the bending or "climbing" of the liquid along the walls of the container.
-
Every time he shook it I couldn’t help but think the sound it made was the same as my bed while doing a certain activity.
-
Now call Styropyro and shoot some lasers in there
-
state of peace became supercriticical listening to those shakes
-
That shaking and squeaking was driving me crazy.
-
You promised a yellow boat but all I see is a semisphere of styrofoam.
