The four five horsemen of chemistry: Ethanol, Dry ethanol, ice cold ethanol, boiling ethanol, distilled water
-
This man made Merocyanine to save money but made $1000 diamond sparkling water consistency
-
Moral of the video: If you want to solve a problem, add ethanol to it
-
You're sitting on a gold mine bro. Selling MOED and Red Mercury should make enough to keep this channel going for decades :P
-
“Ice Cold Ethanol” would make a great band name.
-
Now that you did it, you could upload your thumbnail to the Wikipedia. I'm sure a lot of people would be very pleased of see some HQ picture of this, with the solvents named with tags.

"I still managed to make way more product than I needed, and I also learned something in the end, so this mistake really didn't bother me that much." This is why you are good at what you do.

21:07 the moment he said "liquid rocket propellants" I sat up in bed from pure excitement. nilered, don't forget to take care of your glassware, too. we don't want something like the Great Plasma Shattering again...
-
My life motto: "But it's like... Whatever"
-
Holy hell, those self made rocket propellants

NileRed: Does something Looks back Squirms in slight regret
-
Ahhh, NileRed, my favourite cooking channel.
-
Your voice is so relaxing.
-
Have you tried making the Vanillin derivative? It should still be solvatochromic but produce different colors.
-
Awesome video, NR! Strictly speaking, the two structures of MOED are resonance forms, not distinct equilibrating minima. Polar solvents cause a polarization of the electron density that makes the charged resonance form more representative of the true structure than the neutral form. As this occurs, the energy gap between the ground and excited states shrinks, causing a shift in color toward red.

5:13 I can almost hear the roommate from off-screen: "Nile, have you seen my vodka?? I had it in the freezer." -- "Nu-uh."
-
Why don't you change the foto in Wikipedia with yours? Awesome video
-
Idea for edible chem: synthesize calcium sulfate and make tofu.
-
As a lifelong lover of chemistry, this is one of my favorite channels. At every step, I couldn't help but come up with explanations, rationales, or hypotheses for why things happened as they did. Keep up the good work!

16:08 - It makes a beautiful color when you use acetone as the solvent (second in from right).
