Thunderf00t - 2014-04-22
Weird, weird shit happens when alkali metals such as sodium, potassium and so on react with water. The bottom line is that noone has looked at this sort of thing in detail for about 100 years. It is therefore not unsurprising that no one was crazy enough to try to get close enough to these explosions to see if anything interesting was happening. .....oh boy does interesting stuff happen.

People describe me as dense but I still float on water.
Zothaqqua You sure can! Just learn to eat enough to gain 10% body mass of fat extra, quaranteed to float!
101m4n, I believe that would be implode??
Yeah but even cement will float if it's filled with enough air, especially hot air. LOL
Leather Rebel Justice , I have never in my life been able to float and I'm dense
Dad joke; 1,000,000,000e2,000
Damn Thunderf00t. If no one knows what makes the reaction behave like that then we must conclude that it is because god made it so. You should know this by now! Come on man.
TheHydrogen4 God looked in the mirror and saw Dog (and vice versa). God did all the work. Dog won that round. Ipso facto...
Interesting how so many of f00t's experiments end with an explosion.
+Aelius Magnus One of those names is significantly more marketable than the other.
+tibschris Michael f00t, obviously
@n8 Thanks, precisely.
"Michael Foot: when science kicks ass"
+Michael Slade Makes me wonder if his Ana Kasparian experiment also ended in such way. :D
He should be a mythbuster XD
someone should film this with a phantom camera so we can get a better sense of the effect. You should ask the slowmo guys or smartereveryday if they could try it
@root Toor i think the issue there is, all the camera will see is the glass.
@mike mackenzie-grieve Film from above then?
That might be a option,
I think it would be difficult for him to get the slowmo guys or smartereveryday to work with him, they would not like to lose any viewers, and with thunderfoot talking about the things hes talking about, he might end up making feminists, creationists, muslims, attacking any other channel that he'll work with.
Vadim muslims ?
Must be cool to discover a new property. Even if you can't explain it.
Just like the scientists of old, Can you imagine what it must have felt like to discover and experiment on pure oxygen? That must of been so rewarding and exiting.
haha, at this 1:58 point I thought he was gonna say "and then it changed into a black hole that has since been consuming my laboratory."
:Þ
i have learned something: do not use invisible metal for building submarines.
...because then you wont find it after you've parked it
@joten70 You will find a huge crater where it was before.
https://en.wikipedia.org/wiki/Aluminium_oxynitride
Invisible metal that won't explode.
That's actually a ceramic.
"Too late"
Boom
You should do a collaboration with slow mo guys with this experiment
@Christopher Schroeder I have since stopped Thunder as he is starting to turn opinion into science
Can you please leave a link of the paper he published?
its called theft. derrrr
It's not just the phantom camera that costs money. You need a very fast lenses, , a computer with the power and storage to handle the footage, and cinema lights. All of this stuff the slow mo guys already have so it would be great if he could do a collab with him.
if the research is promising enough, he could get budget from any public agency
Please apply for a research grant. Id like to know my tax money was sometimes used for worthwhile things.
I don't want no exploding whale tank on my Klingon bird of prey.
I'm not saying it was aliens...
Ok, it's aliens.
Dang aliens! They done stoled my wife!
can it be that you .. have created pure greeeeeennn , ( blackadder reference)
+jojowhizz and that blue was way bluer than the famous blue stone of galveston.
lol
an unexplained Phenomenon?? then it must be JEHOVAAAH
You'd need to try laser light shining on the metal as it transitions from black to transparent before concluding it's IoR has changed to equal that of water. It could be a "cloaking" effect or some other exotic light bending state. Be fun to find out :)
also if that's possible, introduce the water slowly to the NaK drop and try to get to a point where the drop is transparent, but not yet exploding
@Sirius Black Since it's a coulombic explosion that depends on the metal exchanging electrons with the water, the effect may also depend on this exchange. Might be able to delay the inevitable, but not for long.
I wonder what the Periodic Videos channel would make of this.
+Fudmottin I was going to suggest a collaboration on this subject, it would be amazing!
You are correct on this one, in fact once all of the HOMO electrons are gone from the metal, the only ground state left for photons to excite is too high energy for absorption; as a result the metal becomes transparent to visible light.
+Exascale
so invisibilty = high electrically charged material?
Not exactly, I encourage you to look into QED and Feynman's
papers.
They would first discredit him and then make their own purporting to have discovered it.
You may well be the first Noble winning YouTuber!
Are you calling him a potato?
Hell yeah. I love this shit. Chemistry is the only real "magic" there is. Thunder these videos rock.
@*****
Maybe you're too young to know what he's on about...

@***** It's magic, dude.
@Alexandre Tremblay

Science = Magic
@warbossworm Science > Magic
@Thunderf00t This is fantastic research, Id like to see this at 2500 fps
One word.
SWEEEEEEEET!
my guess would be that it can float because A: some kind of Leidenfrost effect or B: it rotating fast enough for the Magnus effect to kick in.
or C: magic
it may be magnus effect because in the contained chamber the gas would be spinning it incredibly fast as its made, but it couldnt be leidenfrost because the gas probably would not be light enough and/or moving fast enough upwards or outwards to float an object that shape and that mass(since normally it only happens with small amounts of water and when it does happen with water the gas creates something that looks like a slightly hallowed half sphere that acts almost like a parachute)
I see leidenfrost as more likely at a first glance. If that isn't it, It couldn't be the Magnus effect because the drop would have to constantly be changing the axis about which it spins as well as moving quicker to the side. The magnus effect must be combining with some other force if that were to be the cause.
It's not phenomena, it finally went "Super" Aldo Nova :)
I may be a bit late, but the most probable reason is that the lightest element in the periodic table is also created AKA hydrogen which lifts the droplet. the reason why the droplet then explodes is that some of the sodium/potassium is floating over the hydrogen in an area where there is little to no water/water vapour and when the reaction starts to slow down, the amount of hydrogen isn't enough to keep the droplet floating so it sinks making the unreacted metals quickly react exothermally so an explosion occurs. I don't know about the colour change, but looking from the top and from the bottom could have caused refraction and made blue light more visible
I'll be honest, I thought this was going to be a pseudo science debunking video when I clicked on it.
Wow... SCIENCE!
Thunderf00t: I'm not sure if you read all these comments but I don't know how to send a message directly to you... Anyways:
I'm no scientist (I'm going to college for a "fine arts" degree) but watching your videos really makes me wish I could partake in science! In high school it seemed most kids thought science was boring and just about following directions. But seeing stuff like this really shows that science can be very interesting and mysterious. There are always mysteries, and hope that someday we will solve them, and it must be an amazing feeling to be someone who works to push our knowledge base further.
What you present here is very cool stuff! I think it's beneficial to expose your subscribers to not only arguments against religion and feminism but also to this stuff. Since I have very little formal background in science, I'm more hesitant to click on something like this than on "Creationist Stupidity" stuff but I took the leap and found something even more interesting!
Videos like this, while most viewers (including me) may not understand everything, are very important. Because you've convinced me that if I ever have kids, I will do what I can to get them curious about science. I think the work you do is very positive and we need more of this kind of stuff, and more exposure in popular culture for young people.
Thank you 雷足！
Switch your major. STEM degree >>> art degree.
3:00 mb it has to do something with surface tension
Found an article that describes sodium becoming transparent under high pressures dated 2009 from stony brook.
It was accomplished under high pressure and i wonder if you found a different way of achieving the same subatomic result. If you could find a way to control it under pressure you may keep it stable long enough for a complete analysis. My guess as to the reason of explosion is temp.
I want transparent Stalinium!
KV-2's viewports will be indestructible!
Transparent Uranium, bring it to class and end school in less than a day
My first thought is that the green to blue to black to clear transition suggests a widening or changing band gap. Maybe because of increasing temperature changing the alloy's atomic orbital overlap to the point where it's UV width and lets visible light through. That seems really unlikely though if the whole ball is still Na/K.
Maybe a more reasonable case is that K reacts more preferably but that at the potentially high temperatures of reaction, molten KOH and Na are miscible resulting in a changing band gap.
Can you change the ratio of K to Na to see if that changes the result? Can you monitor the UV absorption of the ball? Can you stick graphite rods in to see if the ball is conductive?
@David Naoum I'll have to rewatch because I forget his explanation but even if you have a reaction with the valence (outer shell) electrons, the inner shell electrons will still be there and could absorb light.
+David Naoum Yes but that's with only the very outer layer of the metal losing its electrons, and even that causes the substance to expand with such high acceleration that the whole thing happened in a few micro seconds - a whole ball of cations would cause it to fly apart many times faster stil. The energy required to strip all the valance electrons (and that's ignoring all the inner shell orbitals) from a ball of metals would be so enormous that this could never feasibly occur anyway, but if it hypothetically could exist, it would fly apart with such force I'm sure it would at least destroy the container and surrounding equipment.
I support this kind of thought, maybe this phenomen is similar to the colors appearing in a charge transfer complex
And sorry for my english
Yes, I think that the silver "color" of a material is inherent with the metallic properties of the material and the interaction of the free electrons with the photons giving rise to the metallic surface.
At the moment it gets transparent it ceases to be a metal. It no longer has metallic properties.
It could be interesting to use electrodes to monitor the conductivity during the process. But the conductivity may remain due to free ions produced from the metal.
Some thoughts are coming up here; from what I can recall, if you deposit a thin metal substrate onto say a piece of glass, then you will get a colored transparency from it. For example a substrate of copper is dark green. Perhaps that sodium and potassium would yield that dark blue color that is mentioned in the clip. That is strictly tied with the band gaps you mention of course. By that reasoning the black ball is where the metal has diluted that it gets transparent. Perhaps it is split into very small molecules preventing it from being a solid metal. As it reacts with water it dilutes and at the end all of the metal is gone. The reaction that sustained the ball loses momentum and it pops.
Could he hypothetically get different pieces of glass tuned to filter different frequencies and use them as slides on which he could do small examples of this reaction while filming it? That way he could narrow down exactly what wavelengths pass through it. That might shed some light, so to speak, on the exact effect happening here. Alternatively, if he could use regular glass slides and use different LEDs at different frequencies to back light them, he might figure it out that way as well.
Ah, now I remember why I'm subscribed to T-f00t. I tend to disagree with the man on a lot of things but when he's good, he's good. I think I may even have to start sponsoring him one of these days.
@Liekkek Realization is not a passive process.
Though my remark was a bit tongue-in-cheek, Thunderfoot has yet to say anything that doesn't make perfect sense.
@Liekkek took the words right outta my mouth. Living in a virtual echo-chamber where all I hear is my established views repeated back to me is not my style. Many of my subscriptions are lefties who I vehemently disagree with on a lot of things but that doesn't mean I don't like listening to what they have to say. There are some things I'll never agree with T-f00t on--I am a right-winger, a Muslim and I have a healthy respect for women, for example--but that doesn't make me think any less of him. The only videos of his I don't watch are his awkward attempts at wooing Kasparian but that's just because they make me cringe. Respectfully.
@Gísli Brynjólfsson Just wondering:
Are you saying that Thunderfoot does not respect women, or that Muslims or right-wingers somehow can't respect women, but you're an exception to that rule?
I'm not a fan of any of his TYT related stuff either.
@racoiaws Yeah, I realized as soon as I posted that comment that "healthy respect for women" wasn't the correct phrase... I wanted to address his penchant for picking on silly little "feminists" but I'm not sure how to do so eloquently. Can I pull the second language card at this point? I don't claim to be an exception to any rule (although I was pretty good at basketball for a white guy), I just meant to point out that since T-f00t is an atheist liberal who clearly despises Islam, we don't tend to agree on much on a personal level. But I'm pretty much a fanboy regardless and greatly look forward to his uploads. Even when I don't agree with his views, I can at least marvel at his neck. It's a thing of beauty.
Gísli Brynjólfsson I can somewhat relate to you, man. I'm a muslim who is on the right-wing side and agrees with some conservative ideas. Eventhough T-f00t really just despise Islam, I kinda understand from his view on why he did. Not to say that I 100% agreed with all he said, but when he did something good, he nailed it good.
I prefer to watch all of his kickstarter "invention" debunking videos, his science-ey stuffs, and his flat-earthers+feminists debunks. I'm not really interested to watch his anti-muslim videos, but maybe if I'm prepared enough I'm gonna try watch it.
It looks like it's not floating so much as being supported by the Leidenfrost effect. When the heat is not longer high enough to support it, it drops into the water and explodes.
That is exactly what I thought
same thought
The Leidenfrost effect would be enough to lift the droplet on top of the water.
i was also under the impression (due to the "recorded at 500 frames per second" disclaimer at the bottom) that this is super slow motion video. so is there even enough time for gravity to drag it down between the time it turns transparent and when it explodes?
That phenomenon is just a distraction from Benghazi.
Thanks Obama!
Any updates on what it was?
+DrHotelMario Oh hello there. Edit: wait, 3 weeks ago
Something tells me DrHotelMario may not be the name of a real plumber.
Nigga u fat as hell lose some damn weight 🚷
Btw I contrary to what everybody else says I like your exposing the stupidity of feminism videos, they are informative and hilarious. I've been a subscriber for a few years now and I really like this channel. So keep the videos coming. Whatever the topic may be.
I'd love to see what happens if you did this with some alcohol in the water to break the water's tension :) sink or swim?
Science: Pulling off miracles everyday.
Religion: Sometimes depending on what people say and how they interpreted it, not to mention there may a disagreement about the exact order of events among theologians, oh and there could be different beliefs surrounding the exact depiction of what happened therefore leading to different belief systems...... um....yeah.
SOO COOL!! Keep doin what ur doin!!
Thunder foot is going to be an alchemist before long. :)
He will have seen...it
Really interesting video. I love this stuff Thunderf00t
Record this reaction with an infrared camera please.
Nobody knows why this happens
Must be God
*runs away*
You mean must be MY god, your god couldn't make the sky turn red if he even tried.
One of the most amazing things I have ever seen. Thanks for the work you are doing.
If you float filter paper on water and add a small piece of sodium, it also goes invisible... or if you have a table to waste, you can put wet filter paper on the table - this lets you see the transparent sodium without going to the explosion phase. You also see it oscillate between metallic and glass phase
I think YouTube keeps removing the link, so search for Thoisoi2's video called "Making Transparent Metal? Invisible Sodium chemical experiment!"
@Darc Gibson
The conditions are different, so it's "that" not "this"
+Larzsolice I found out the hard, boring way that some people set their channels to auto-silence URL's. You can check if this is the case by logging out and looking at where your comment should have been.
@htomerif
Not my channel, I don't post videos on YouTube. But thanks. I will try post the link in my next post - if there is no next post then youtube took it off.
@Larzsolice They don't have to be links to videos. I posted a link to the definition of 'cardinality' in terms of number and set theory in the comments on a Numberphile video.
To me, it looked like the link posted just fine, though I wrote a mathematical proof to go along with it. I was surprised and a bit annoyed when no one responded to it.
I signed out of youtube/google+/gmail and looked at the video comments just didnt show up. It didn't tell me anything or make it not show up when I was signed in, but no one else could see it.
It re-posted just fine when I removed the link.
Sorry for the somewhat long response, but it seemed like I didnt communicate exactly whats going on clearly enough before.
Amazing video! I never though that even this reaction can be so complex. Any chance to do spectroscopy on it?
These are the kind of videos that I sub to you for.
I need me a pair of humpback whales....post haste!
this is my version of how to make invisible metal: get some metal, melt a hole in it. There, Invisible metal that you can show your friends!
You need to make more of these bids and less about political bs.
i agree with you mate. science is way more interesting than crazy ass feminists and stupid creationists!
While I agree the science video's are epic :P how many experiments did you just watch? I dont know either but there were many :P you know that shit takes time to set up right? More so when you have to faf about with camera's, lighting, angles etc etc.... More time is needed to edit and render out the video blah blah... :P Whats wrong with TF using the time between collecting all the data together to show us what the loonie lot are up to? all the video's are informative, if you dont want to see the political stuff you can click away after 30 secs right??
@frackcha True, I actually don't watch his feminism videos because I think they are a waist of time. I'd rather wait for him to uplo0ad a good video than have clog up my front page with his pissing math Watson.
science is awesome!
Man, this is crazy good!! Keep up your research!!
IF YOU ARE A SORCERER, MAKE ME YOUR APPRENTICE !!!! okeloloeo... im serious/
Jeremy J. - 2015-05-14
I believe it doesn´t sink because of the Leidenfrost effect: It´s being held up by the rushing steam. There is such a high temperature gradient, that the Leidenfrost effect must at least play a role in it.
Schmoo - 2018-02-06
I'm amazed, this was one of the kindest comment-thread i ever read. Why can't all youtube comment sektions be like this? amazingly refreshing. I think, that it can't be ignored, that the whole effekt took place in around 1 second, given the 500 frames a second camera. So the evaporation and heat differenz could play a signifikant role. A drop of really hot metal probably also floats for a really short time in water. Aber ich bin nur n simpler Informatik-Student, also was weiß ich schon :)
Scienciness Feeling - 2018-02-16
Schmoo, I wish to fully support and endorse your first sentence.
Scienciness Feeling - 2018-02-16
Richard Smith: Interesting point, but it would be interesting to test your theory. Could one float an object slightly more dense than the liquid below it if the upper object was heated enough to produce a produce a Leidenfrost effect?
Tom Haflinger - 2018-03-03
I would say that the average density of this object (hollow or not, the mass divided by the volume it takes up) is most likely greater than that of the water. You see how the surface of the water is bent downward in the middle like a trampoline? Objects that are floating due to buoyancy have a tendency to work their way toward the outer edge of the vessel, but the droplet instead prefers to sit in the center.
Walker - 2020-01-06
I think it’s actually the fingerfuck theory
