- Can metals be melted in hot water or just by the heat of a human hand?
Some can and in this video I melt a bunch of them!
Here's where I bought the samples if you are interested in trying this yourself:
(it's much better in real life than on video ;)
www.crystalgrowing-shop.com (German site, most is available on eBay too)
- Rose's metal
- Wood's metal
- Bi-Pb-In-Sn-Cd (in rare cases called French's metal)
www.smart-elements.com
- cesium
- gallium in vacuum ampoule
www.eBay.com
- gallium
- Field's metal
The mercury is from antique mercury thermometers.

If you are interested in elements you should check out the rest of his website. His thorium sample is the best I have ever seen!
There are only few sources about the very specialized Na-K-Cs alloy. I have since the making of this video found another source that mentions these compositions and melting points:
12% Na, 47% K, 41% Cs = Melting point -78 C
3% Na, 24% Na, 73% Cs = Melting point -76 C
So no doubt that Na-K-Cs is the metallic alloy with the lowest melting point at around -78 C, but the exact composition is a bit of a mystery...

I loved how Brainiac75 puts his own subtitles, english is not my native language, so all english video i see i put subtitles. Glad that Braniac75 cares about people like me :)
3:55 that sound is so satisfying :P
is that a sound effect or the real audio?
Good luck finding the francium. :-)
I like how Caesium gets a green rating on safety.
Go ahead and take it out of the ampule and see how it spontaneously explodes as you touch it.
Cs-K-Na alloy? i'd love to see that react with water.
*obtains one kilogram sample, throws in ocean, someone 74 miles away sees huge mushroom cloud*
Kaboom!
@Benjamin Joshua Beggs Actually Cesium is less impressive than Potassium at the same mass because while it is more reactive it is also much more dense.
Yeah that would be a huge explosion
Brainiac: Mercury is very toxic
Cody's Lab: *filling up tub of Mercury for a bath*
Also taking a sip of it and spitting it out
I JUST LOOVE HOW SCIENTIFIC YOU ARE!
Keep that voice going too!
Thank you!
I did try to 'tell an escalating story' and use the samples in different ways instead of just randomly showing a bunch of melting samples. Glad you liked it.
_maybe if I could just get some francium..._
I love your humor. xD
Thank you!
This particular video was actually quite research intensive for me so it took a loooong time to put together from idea to final editing.
It's nice to hear that I didn't waste my time :)
I used deionized water to keep the alloys as pure as possible. I'll give you one more chance to explain why it worked anyway ;)
(Hint: DI water is not a good conductor).
Thanks for watching!
That was from eBay. A British seller called 'morgaine-le-feys-cat'. They still have some samples for sale - search for 'molybdenym rods'.
Thanks for watching!
I think you are gonna be my favorite channel for a long, long time to come.
Thanks :) Much more content to come!
Wow it's pretty amazing that you got ahold of Cs. Its such a crazy element to think of having in such a fragile glass ampule! This shit instantly catches fire in contact with air and is just extremly dangerous!
Your channel is awesome ass hell, insta- subscription!
This is also a great showcase of the high thermal conductivity of metals.
Yes, they quickly heat up when in touch with hot water. Good for the impatient internet audience :D
Your videos are so great, watch them several times a day.
"I Wish Mercury Wludnt be So stupidly toxic" 😂
Codyslab:
literally all cells: we use liquids to survive
Although your videos are rare, they are among the best produced on CZcams and are excellently entertaining! A job well done Sir! :)
Ok that makes sense now. I will think of different elements and alloys relatively from now instead. Thanks and keep up the great videos!!!
I'm a graduate student in materials science, and I still learn something from each of your videos! Love your videos, and keep up the great work! Subscribed.
I bought them from Germany - neighbour country to Denmark. Denmark is too small to have a commercial market for amateurs like me on the 'weird' things I'm interested in. So most things I show are imported by myself :)
always nice to see a new vid from you Brainiac :)
Brain, your videos are some of the best i have seen, and some of the most unique!
You should try to do another video like this but go into more detail about the metals and expand to other low melting metals like newtons metal, galinstan, and others!
I like how you incorporate comedy into your videos, especially in this one at 3:14.
These are really great videos! There's a lot of effort put into them, and the presentation is clear and very interesting. Keep it up!
This video is very good. I like the progression on data that you show us.
Stumbled upon this, it was informative, fun to watch and nicely done
I subscribed for the SCIENCE!!! Thank you for the simple and informative format of your videos. Keep them coming.
Thank you and welcome aboard :) Much more to come!
Love your vids mate!
They are very interesting and I enjoy them immensely!
amazing work, this is beautifully done
Your videos are always super interesting, great job, keep doing them ;)
Love the music at 4:10 so epic!
You have a very nice elemental collection
Always nice to upload a new video - it is the culmination of a fun and exciting process but also sometimes hard and frustrating work :)
Thanks for watching and commenting!
thanks for the great video very informative! i love all your samples their nice, I enjoyed watching very entertaining! and the chart showing the danger zones and melting points was a huge plus very appreciated and well done!
Thanks for watching and commenting :)
You sir have got a sub from me, I am thoroughly impressed by your narration and acquisition of such interesting and cool metals. Very cool stuff!!
Thanks, and welcome on the team :)
I am still surprised by what is possible to buy - if you look for it. So stay tuned for more interesting element and chemical samples.
brainiac75 Thank you too, I enjoy the elements myself, being quite the science dork. One element I've never even really seen on video is Beryllium, looks kinda like Aluminium, I Lightest metal other than Lithium. Where I live there was a Beryllium plant that sickened and killed many, it's been closed down for years but the area is pretty much untouched for fear of disturbing the soil and releasing Be dust. That stuff is no joke.
It does seem quite weird but it is because the alloying elements bond in metallic crystals and acts like a single compound in stead of just a mechanical mixture of metals. Wikipedia has some info on this in the article 'Alloy'.
Not all metals will alloy - lead and aluminium for example. They will not bond in an alloy crystal so if you mix powder of lead and aluminium and melt it they will separate with lead melting first.
Thanks for watching!
Great video. Very informative. I would love to see a similar video showing the effect of magnetism on these liquid metals. Good stuff. Keep it up.
You left out poor copernicium😟Its a gas at room temperature
And so would anyone handling it be
He is talking about metals Oneshooter
@@flydrop8822 Copernicium is a metal
@Benjamin Joshua Beggs It's boiling point has been found to be around 183 degrees fahrenheit, so it's probably not gas, but liquid at room temperature.
@@limecyanizer4394 wtf i dont know why i said that, maybe i was replying to someone else.
Point is thought, copernicium is extremely unstable and radioactive, like Muzik said anyone handling a big enough amount of it(and when i say big enough i say a few mg) would die. Actually, getting that amount is probably impossible with our current technology. Transuranic elements are an obscure group of elements from atomic bomb makers, to atomic bomb residuals, to atomic bombs AS-IS. Copernicium is likely from the last group.
Dude, your videos are awesome!!! Keep it up and your art will reward you greatly!! :-)
Thank you! Greetings to Australia :)
To James Thompson: I can't reply directly to your comment. Have you disabled replies or is the new comment system just messing up? There's a reply button but I get the message 'You are not allowed to comment on this post'. Great...
Anyways, here's my answer: I did consider Galinstan but had some issues with it. It is nice that it is liquid at room temperature but it wets almost everything because of the gallium so it's not very practical (+ expensive!). The biggest issue though is the controversy about it's melting point. Eutectic gallium, indium, tin is supposed to melt at +11C but the inventors of Galinstan (it's actually a registrered brand name) claims a melting point of -19C (maybe by addition of antimony and bismuth but it's very unclear).
James Thompson It actually sounds like a good idea to make the galinstan myself. There seems to be many opinions about its freezing/melting point but I could test my own sample.
Thanks for sharing your observations. Ah well, all the tings I have to do when time comes :)
I mentioned the dangers of cesium in my previous video czcams.com/video/9gB775y4FbE/video.html . But I guess for a stand alone video I should have at least made a note on the reactivity in the video.
Francium? Good luck.
Trenton Keller Hehe, I probably would win a Nobel prize if I managed to obtain a visible amount of francium. Hard odds with such a volatile element :)
brainiac75 i cannot find any samples of Fields metal. I would REALLY appreciate it if you could find where you bought it and send me the link? Thank you
Austin _game Hi. I can't remember where I bought my sample of Field's metal. But here are three samples for sale from an eBayer that I have good experiences with: www.ebay.co.uk/sch/m.html?_odkw=&_ssn=morgaine-le-feys-cat&hash=item58c3d2452e&item=381242459438&_osacat=0&_from=R40&_trksid=p2046732.m570.l1313.TR1.TRC0.A0.H0.Xfield%27s+metal.TRS0&_nkw=field%27s+metal&_sacat=0
Apart from in old thermometers and barometers, it is used in eg. sphygmomanometers (for measuring blood pressure) and in some tilt switches. In very small amounts it is used in fluorescent lamps. Until recently it was also used in dental fillings (amalgams) but it is being phased out.
Thanks for watching!
These videos are great! Thanks a lot for taking the time to research and share your knowledge with us :) much appreciated
Awesome work brainiac75
Phumla Kona Thank you very much :)
I love the health meter with the faces!
really like these man ! just found your channel and love it :D
+TheEliteHaxz
Awesome! Welcome aboard - more to come :)
+Brainiac75 can't wait man :D
Thank you very much!
I aim for quality over quantity so it's nice to hear that I don't fail at both ;)
But with the surprisingly fast growing numbers of subscribers I will try to upload a little more frequent. It just takes so long time for an amateur like me to put these together in my spare time :)
This is very cool. Please keep making videos. Great work :)
Thanks, I will carry on :)
Hi again. My stove is not of the induction type. It's a glass-ceramic with radiant heating coils so it works well even with non-conducting materials. Sometimes the simple answer is the right one ;)
Thanks for your insight; Yeah, I was aware that Mercury was used back in the day; I wasn't sure how some of those alloys you demonstrated would solidify, particularly the one that didn't shrink upon cooling. Thanks for making. ;)
That's like choosing between plague and cholera...
If it broke in my hand I would prefer a mercury vial over a caesium one...
If it rolled of the table and smashed on the floor I would probably prefer caesium over mercury. The caesium would quickly react and start a fire but I could easily take care of that. Removing toxic mercury completely is not as easy as taking out a small fire...
I fear both scenarios and do everything to avoid it happening!
Thanks for watching.
Need to add Galinstan... Gallium, Indium, Tin
Also I think that one of the last 10 new elements that's a metal is a gas at room temp
In particular, it would be great to see some practical advice for handling gallium compounds. For instance, is there an easy way to coat glass with gallium oxide so it doesn't wet? I tried melting gallium under water... the water became a dirty blackened mess. I've had not yet tried oil.
1 coat the glass with gallum
2 heat it
3 it will oxidize
4 use it
Great video and I kept waiting for the T-1000 to emerge!
Thank you :)
I have considered trying to get an effect with a magnet and these metals when molten. But I believe they will be too neutral to see any effect. I'll give it a try at some point though.
Not really. They may be shiny but it's hard (impossible?) to get a large liquid to solidify perfectly without changing shape when the crystals start forming. So it will be a very uneven mirror surface which is useless for a precision reflector like in a telescope. As far as I know it has never been done.
Liquid mirror telescopes are used though.
Thanks for watching.
Great video and explanation, thank you.
Molten aluminium is heated to at least 660*C. The autoignition temperature of paper is between 218-450*C depending on thickness and type. So the molten aluminium is more than hot enough to heat the paper (or wood) to its ignition point without any flame or sparks.
Nice and clean video, informations, display...
Just if you have had include very common and interesting eutectic alloy gallinstan.
These videos are awesome!
It's nice that the KNaCs alloy is non-toxic! Completely safe...
Thanks.
Yes, permanent magnets are annoying in the way that they are always waiting for you to make a mistake. And with neodymium magnets a mistake can easily destroy expensive magnets. It's so hard to be perfect around these magnets all the time :) At least you weren't hit in the eyes by the shrapnel.
Always interesting videos - thanks!
As always, thanks for watching :)
I really enjoyed this thank you.
Come on, you did a good casting. I love the texture of the casted Wood's metal.
Your videos are freakin awesome man.
love this channel
I dig the "pop!" at 3:55, and yes, go for Francium haha !
Excellent :)
this video is much more better than the household hacker one
Thank you!
I did consider it but had some issues with it. It is nice that it is liquid at room temperature but it wets almost everything because of the gallium so it's not very practical (+ expensive!).

Another excellent video! I was wondering how you were going to get the casting out from the tube without a release agent!
Hey, you should check out the indium-gallium alloys! they're super cool, nontoxic, and I don't think they stain as much as gallium alone. Also, very safe. Honestly, the stuff deserves its own video
I always like your video's, good work
Amazing explanation!!!!
8:17, that derp emoji lmao
As I remember, it was from a Dutch guy on eBay - can't find it now. The seller 'mr.bismuth' on eBay has some for sale. Lots of samples are also available on Amazon.
Very cool dude, doin what you love
Great video !
One time my mum accidently dropped some gallium on my carpet. We got it out with an hairdryer and a pipet, but it took a while.
Can you upload another video? We love your videos...
That's nice of you to use our antiquated Fahrenheit system to make it easier for us to understand. You don't have to do that, though. Mange tak!
Nice video and it was cool when the metal was at the bottom of the cup. Also is there a way you can shape the metal when it's melted
It would be too much work, and gravity would be more effective if I had the right filter for the mercury. I have used double-sided tape to clean it (and bought a better sample without glass fragments from thermometers...).
Gallium also has a very high surface tension. Here in dynes/cm:
mercury ~487
gallium ~723 (tested in nitrogen atmosphere so may not be comparable...)
water ~72
So gallium has high surface tension but it tends to wet things and has lower density than mercury. I guess that's why tungsten is best floated on mercury :)
that was a good one, visually interesting too.
i bought some powerful magnets cuz of your videos..thanks brother..i used safety alot but in the end i threw them together and forgot i took off the tape surrounding them and believe me they explod like a grenade with sparks as im sure people seen on other vids...lesson learned..great videos tho
Those smileys are great
Tungsten is so dense that it should sink in most liquid metals.
With that said I have seen small samples of tungsten carbide float on mercury because mercury has a very high surface tension (6-7 times higher than water).
Hello Sir, great video. My guess: You heated the water before putting it on induction stove. The alloys sometimes work with the induction (3:14, maybe because of the tin content?).
We made alkali metal alloys in college, many are much more reactive than any pure alkali metal. Cesium potassium sodium(or cesium + NaK) will eat through plastic syringes then ignite when it makes it to atmosphere. The stuff is viscous. Oh, and drop it in water and kaboom. Most alkalies I would not call explosive in water, just very active, however, that stuff was explosive.
+Richard Smith
I believe it. CsNaK is just a crazy alloy. I would not like to handle it - even though my curosity would probably win if I had the chance :D
+Richard Smith What's causing the extreme activity of the alloy compared to pure Cs? Is it that the more electronegative sodium causes the electrons to be even less strongly bonded to the Cs nucleus?
@@SkyWKing i wonder the same.
This video, just like your other ones, is great, but this obe is especially good, so please make other videos with interesting facts like this one.
Thanks for watching. This old video (2013) is definitely one of the first where I really starting telling a story with my videos. I will try to do the same in future videos.
+Brainiac75 I really loved the last metal alloy (Na-K-Cs), it was a very interesting fact to know, but I couldn't find it anywhere. If you are sure it is true, then I'd love to see videos with interesting, nonobviuos facts like this one. Greetings from Macedonia.
The Na-K-Cs is a very specialized alloy so there isn't much info about. And it is way too reactive to be for sale for and handled by a private person like me - in fact I don't think anyone sells it. It is just made by those who need it :) It is mentioned in the book 'Handbook of Thermodynamic and Transport Properties of Alkali Metals'. The composition may be different though, since another book has another composition. You can find the following on Google books. Search for the book 'Alloys: Preparation, Properties, Applications'. On page 278 visible in the preview the following compositions are mentioned:
12% Na, 47% K, 41% Cs = Melting point -78 C
3% Na, 24% Na, 73% Cs = Melting point -76 C
So I have at least two sources saying it it the lowest melting alloy. But the exact composition I'm not 100% sure on.
Greetings back from Denmark.
+Brainiac75 Thank you very much for your information. I'll look that up on google. About the handling, that's obvious, it is dangerous, anyways, I'm looking forward to seeing another excellent video from you like this one.
Always fun videos!!
:)
ur channel is awesome. very interesting
This is a great channel, please keep it up.
BTW do you know what the melting point of francium is?
Pure metallic indium is not toxic.
Compounds of indium can however be toxic (especially the water soluble indium (III) compounds).
I laughed way to hard when you said "Maybe if I could get some Francium!"
Not only because of the way you said it but because Francium would be pretty much impossible to get a hold of.
And if you did, you likely wouldn't be able to hold anything else.
Fahrenheit?
I always thought in Denmark they would use Celsius?
Here in denmark we use celcius, i think he used fahrenheit for the international viewers.
And by international you mean the Bahamas, Belize, palau, Cayman islands and that north american marketing experiment.
Fahrenheit is the easier system to use. Lets not be insulting.
More precise measurement for me.
Thanks :)
Yes, I will upload a lot more videos but making high quality videos takes time and money and my dayjob is keeping my busy at the moment. If everything goes as planned my next video will be a closer look of the grades of neodymium magnets including a little comparison with the much weaker ferrite magnets. I have summer vacation in July so I will definitely upload there - hopefully a little sooner.
Could be the case. The seller doesn't reveal what the trick in the ampoule is - could be gallium oxide or indium tin oxide. Apparently ultrahigh-purity gallium with no surface impurities has so high surface tension - higher than mercury - that it is difficult to get to wet anything - just opposite of the gallium with dirty surface in normal atmosphere. Gallium is a really interesting element the more I read about it :)
3:19 Why do they join together? I love you videos man, very interesting. Love observing everything :)
+TheBenchmarkBrothers
Thanks! Why the little drops of molten metal join each other? The bottom of the beaker is a little convex so the little drops fall towards the sides. Where they join the bigger molten blob of metal due to cohesion.
brainiac75
Ah, OK. Thank you very much :)
Thanks for sharing!
hi! I want to share my experience melting tin
well, not pure tin, but tin-containing solder wire.
I think it's quite safe to melt them, you can melt it in a ladle or in a bottle with a stove or butane torch. solder wire usually comes with flux. this flux boils off before the solder melts. so I used some candle wax to prevent oxidation...
Hey Brainiac75, great video! I was just wondering if tin is safe to melt all by itself (i.e without safety equipment like a respirator). I was thinking of buying some but I am not sure if I should.
