The inspiration for this video came from an article in the well-known journal, Applied Chemistry. https://doi.org/10.1002/anie.201605986 In short, we can observe the blue color of solvated electrons not only when alkali metals are dissolved in liquid ammonia but also in water! http://jungwirth.uochb.cas.cz/assets/papers/paper278.pdf _____ 0:00 Sodium-potassium alloy making 3:00 Solvated electrons in liquid ammonia 3:45 NaK and water 4:20 Solvated electrons in water 5:56 I Light a Match with Water! 6:33 Superheated steam and Lithium aluminum hydride 7:17 Superheated steam and sodium-potassium alloy _____ ❤️ 💛 💚 If you enjoy what I do and would like to help me to create unique chemical content please support me on Patreon. __________ Patreon: https://www.patreon.com/ChemicalForce PayPal: @chemicalforce __________ crypto: BTC: 1828WxhTtqohRiQBHgKtdqrmxsGncsjva2 USDT (ETH): 0x2BbFD4aDEc7520301a408eBf7dD87B8b9935e49C ❤️ 💛 💚
I've first seen solvated electrons on Thunderf00t's channel. Your slow motion shots are fantastic as always! Amazing to see this phenomenon in such great detail. Thanks for the video!
The paper he shows is from philip mason witch is no other than thunderfoot ;)
Same. Wasn't it TF who also submitted one of the earlier papers into the journal too?
@@dedr4m yes he discovered the Coulomb explosion and did a lot of the research NaK! Yeah, science!
I remember when thunderfoot used to be good. Now he's just shit.
Honestly wish he did more of the cool science stuff, instead of the reactionary opinionated stuff he often brings out these days.
Awesome! Just wanted to make clear for your viewers that "liquid ammonia" here means cryogenic anhydrous ammonia, NOT ammonia dissolved in water (which is what household ammonia is). The NaK would explode on contact with the ammonia water.
So its not piss...?
I knew of NaK from an amateur interest in nuclear energy, but seeing it with ammonia and steam was new! Thank you for putting your cameras in harm's way to get this!
This was such a neat phenomenon when Dr. Mason published it. So cool to see the work being recreated by another fabulous YouTube chemist. Thank you!
That's really nifty stuff. The slow-mo oscillations of the drops as they merge is fascinating, as is the brief appearance of the blue colour.
This is wonderful!! 🤩 Even Thunderfoot and Periodic videos didn't know what this effect was when the droplets turned transparent!! 😁👍 you did it!! 😃😄🎉
This video is mesmerizing. I added it to my psychedelic playlist will watch again when Im tripping
That's a great idea. 👍🏻 Micro Dosin is MEDICINE!!!! 🍄 🍄 🍄 🍄
You are the best in making Videos of chemical reactions. I love your Videos, thank you.
God I love Sodium and Potassium! Two of the coolest elements, in my opinion. Especially when mixed together and in large amounts.
Awesome. I remember a time when finding footage of this experiment on the internet was hard to come by. It's so cool seeing more and more papers (and subsequent footage) of this effect—and all the little details people are now studying/writing about/experimenting with
Wow, this is really illuminating about the different reactions that happen to a reacting NaK droplet on water
Hi Feliks, really asthonishing footage! @2:20 I think it's one of our best "simulation" of what happens when two black holes / neutron stars / stars collide, collapse and finally merge in a single entity! Congratulations! FANTASTIC !!!
Thunderf00t did some incredible work with this phenomenon and is an expert on alkali metals.
You sure have a NaK for these things, don't you? Hah, get it? Knack? NaK? Okay, I'll stop...
😅😅😂
Knack nak, who's there?
That was good! Don’t stop! 😂
Get out! 👉
I thought "should I make a chemistry joke?" But then I thought "Na"
I love the blues that come from oxidation and reactions. My first 'experience' seeing it was as a welder when drilling mild steel would create blue chips and strands. Seeing that reminds me if the colour.
A company called Teledyne-Commodore used sodium-NH3 solvated electron back in the 90's and early '00's. I worked for them. You can look up the applications and details. The chemical reduction process was paired with a high pressure cutting jet that used liquid NH3 to cut into objects to obtain chemical materials that were to be reacted with the solvated electron solution.
These blobs of liquid metal have quite the surface tension. I've only worked with gallium-based liquid metal alloys for electronics cooling before, but they seem to have very similar physical properties.
After watching this video I can't help but think this fella must have the ability to make some truly exotic and outright Kick Ass lava lamps!!! 🤠👍
Video photograph - outstanding. Experimental design - outstanding. Concept - outstanding. Must win some award! Going back on my Patreon support list. Thank you.
Welcome back! :D
I read in a paper that at very high concentrations solvated electrons start to behave like a metal, switching the color from blue to gold. Do you reckon that's what we're seeing when the NaK droplet hits the ammonia at 3:15?
Makes sense, since a metal is an 'electron sea.'
If you want to see the beautiful colour it makes, check out Applied Science's videos on distilling ammonia. He dissolved a bunch of lithium metal, and it turned this beautiful metallic bronze colour in the test tube!
ThoiSoi and Thunderf00t have both pursued many experiments with Na, K, and NaK. these elements are endlessly fascinating and i hope the chemistry community never stops experimenting with them.
The second guy you mentioned is the first author of the paper linked in the description.
The main author of the paper he's referring to is Phillip E Mason. a.k.a. Thunderf00t. It's great to see so many YouTubers now picking up on it.
@@roriegilligan8134 Wow youTube didn't show me your comment before I typed mine. Glad there's a few of us who noticed!
Footage of you cutting alkali metals is oddly satisfying!
Lay a piece of filter paper across a petri dish full of water so that it becomes wet. Drop a small piece of sodium on top. You will see many of the same effects including the solvated electron blue colour, spontaneous ignition and a clear bead of hydroxide that later explodes.
Simple and illustrative.
The blue vapour around the nak ball in water is not from this world. Fascinating!
Hands down the most cinematic chemistry channel on YouTube.A perfect amalgamation of visual art and science. I’ve been hooked ever since I saw the cold phosphorus flame video which was a cinematographic masterpiece.
The slowmotion is WOW just WOW.
Theres a lot to lurn from that! Thank you!
These videos are so enthralling that I'm always half-way through before realizing that I'm watching at 480 and I have to turn up the quality tobwatch it again.
I'm shocked your channel doesn't have more subscribers considering how amazing your work is.
bubbles coming together is so cool in slow motion never expected it to quite literaly be like mitosis in reverse that is wild
The beauty of chemistry at work.
Spectacular slow motion!
Breathtakingly beautiful reactions. Highly recommend this to chemistry teachers 🤓❤
I also highly recommend this to common core 🤓🤓🇺🇸🇺🇸🇺🇸🇺🇸
@@astatalannerrrrrrrrrr
The slo-mo shots are amazing; like real computer graphics!
Absolutely amazing experiments...how do you even imagine lighting a match with water... Brilliant!
Hi! With your videos I can click thumbs-up before watching and I won't be disappointed.
Капля расплавленного гидроксида на поверхности воды, как бы наполненная оранжевым дымом, постепенно становящаяся прозрачной - это одно из самых красивы вещей, которые я видел!
I enjoyed the blue cloud of electrons you got there on the water
Great job! Thanks for making this video.
i knew e- are blue but never seen such beautiful footage
One of the best chemistry experiments ever recorded
6:40 That gave me a chuckle. Honest man.
This was a great one! A very unique spin on the original solvated electron demonstration.
That could be the coolest thing I've ever seen filmed!
dangerous light sparks
That is so alien looking. It could actually be in a movie scene for the next scifi film
Electron blue. Beautiful color.
the slow mo footage of the droplets merging was fantastic!
Raindroplets and hot water meter
The slow mo shots are a testament to the relation of gravity and surface tension.
Those shots where stunning
I had seen drops of alkalai metals turning colorless before popping on the surface of water and had wondered what was going on there. Hydroxide droplets make perfect sense!

Hi Feliks, beautiful exposition as always. However, it is worth noting that you are actually witnessing something even more rare and exotic here than the blue color of solvated electrons - in fact, you are also seeing the violet color of pure sodium gas. If you go to 5:00 in the video you can notice the violet color is not "adhered" to the surface of the metal droplet in the way the solvated electrons are, but rather floats around along with the droplet like a foggy haze. The vapor of potassium is green and that of sodium is violet for the same reason the vapor of iodine is colored, it exists as a homonuclear diatomic gas of Na2, and the electronic states of the molecule are vibronically coupled to the vibrational modes of the two atoms comprising the molecule, causing a multitude of regularly spaced absorption peaks throughout the visible region of the spectrum. Like iodine vapor, it should also fluoresce when irradiated with high energy light!!
@pattheplanter - 2023-05-23
The paper mentioned "part of the metal evaporated". Can you explain the orange swirls in the droplet as the molten hydroxide/metal gets clearer before becoming pure sodium hydroxide?
@Muonium1 - 2023-05-23
@@pattheplanter haven't the slightest idea, but if I had to guess I'd say something to do with the shifting absorption band wavelengths with respect to temperature as seen on the combined spectral plots near the end.
@aretorta - 2023-05-23
@@pattheplanter I was thinking about this too. After some thought I speculate that it is the last bits of metal dissolved in the hydroxide. You can see that, as soon as the swirls appear, transparent orange appears right next to opaque blue. That indicates to me the it's not due to the droplet being red hot, but rather the last bits of sodium and potassium (maybe in clusters???).
@jaywerner1648 - 2023-05-24
Couldn't it be blackbody radiation? NaK has a boiling point of 785C, which is well into the orange range. It's basically just red-hot metal because its been kept from blowing itself apart and continued to react with the surface.
I bet if you look at other videos of alkali metals getting thrown in water, you'd see orange globs of molten metal skittering across the surface due to the leidenfrost effect as well
@Muonium1 - 2023-05-24
@@jaywerner1648 I believe that if it were above the Draper point of 525C the view of the internal swirling blue solvated electrons would be obscured. I have seen these spheres incandescently glowing in other videos though. A simple test would be to turn out the lights while recording!
