For those who skip the comments: there will be an end of year AMA on the channel on Monday, December 19th @ 4pm EST. We hope to see you there!

This really feels like an "It's not a bug, it's a feature" component of our universe

I'm really happy that he was willing to let you guys use his visuals because understanding it when actually seeing it happen is really interesting. His video was excellent and I loved how he actually went through the process multiple different times to try and go with which was really cool

I really love it when scientific channels collaborate and let each other borrow each other's visuals to explain things much more easier.

Worth mentioning while nilered shot that footage the device was provided by Ben over at applied science. He has an amazing YouTube channel where he discusses and explores all sorts of technical things. He built his own scanning electron microscope and made a liquid nitrogen generator.

I knew about supercritical fluids, but I never realized how important they are. It's honestly kind of wild that so many mundane things rely on such a weird state of matter.

For those curious on triple points, a very tangible example is found in geology. The crystals andalusite, sillimanite, and kyanite are made of the same material. But the pressure and temperature experienced when cooling determines what crystal precipitates. A single chunk of rock can naturally have all 3 types forming alongside each other. It's beautiful.

If there's one bad thing I can say about this video, it's that it ends.<br><br><br><br>But that would be supercritical.

Dry cleaner here. Many of us are still using a chemical called Perc (Perchloroethylene) to dry clean. It's extremely non-polar so it is great for addressing oil stains. Under ideal conditions, basically all of it is distilled off and reused. If anyone is worried about it sticking to clothes, they should know that it evaporates very readily and by the time you put it on it will be totally gone.

Was hoping you'd mention Venus. This fact isn't widely shared, and to me it's one of the most fascinating aspects of Venus.

Yoooo happy to see NileRed's footage (with permission) in this video! It really is a great demonstration, he made some great videos on supercritical fluids.

One time I was explaining the Triple Point to my parents - matter being a solid, a liquid, and a gas, all at the same time. To which, my step mom replies, "Is that like when you use the bathroom? It's a solid, a liquid, and a gas." The three of us couldn't stop laughing for the next 30 minutes. 😂😂
