- 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 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!
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 :)
Good luck finding the francium. :-)
3:55 that sound is so satisfying :P
is that a sound effect or the real audio?
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.
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
I JUST LOOVE HOW SCIENTIFIC YOU ARE!
Keep that voice going too!
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!
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 :)
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!
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
Your videos are so great, watch them several times a day.
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 :)
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 ruclips.net/video/9gB775y4FbE/видео.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
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
always nice to see a new vid from you Brainiac :)
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!
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 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 Wish Mercury Wludnt be So stupidly toxic" 😂
Codyslab:
literally all cells: we use liquids to survive
Love your vids mate!
They are very interesting and I enjoy them immensely!
Ok that makes sense now. I will think of different elements and alloys relatively from now instead. Thanks and keep up the great videos!!!
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 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
I think you are gonna be my favorite channel for a long, long time to come.
Thanks :) Much more content to come!
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 :)
Your videos are always super interesting, great job, keep doing them ;)
Although your videos are rare, they are among the best produced on RUclips and are excellently entertaining! A job well done Sir! :)
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.
amazing work, this is beautifully 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!
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.
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 :)
Love the music at 4:10 so epic!
You have a very nice elemental collection
Thank you! Greetings to Australia :)
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.
Dude, your videos are awesome!!! Keep it up and your art will reward you greatly!! :-)
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.
These videos are great! Thanks a lot for taking the time to research and share your knowledge with us :) much appreciated
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
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!
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.
These videos are awesome!
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.
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 ;)
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.
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.
This is very cool. Please keep making videos. Great work :)
Thanks, I will carry on :)
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.
Awesome work brainiac75
Phumla Kona Thank you very much :)
Your videos are freakin awesome man.
Great video and explanation, thank you.
Always interesting videos - thanks!
As always, thanks for watching :)
Great video and I kept waiting for the T-1000 to emerge!
love this channel
I always like your video's, good work
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.
I love the health meter with the faces!
I really enjoyed this thank you.
Great video !
Very cool dude, doin what you love
8:17, that derp emoji lmao
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.
Amazing explanation!!!!
Another excellent video! I was wondering how you were going to get the casting out from the tube without a release agent!
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.
Always fun videos!!
:)
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. ;)
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 :)
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
Intentionally left out:
- Galinstan is a registrered trademark with some controversy about it's melting point.
- NaK is more common than CsKNa but I don't have a sample of it and didn't want to include too many alloys that I can't show. But I had to include CsKNa :)
Many others were left out for the same reason like CsK, GaIn and Bi-Pb-In-Sn-Cd-Tl.
Thanks for watching!
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's nice that the KNaCs alloy is non-toxic! Completely safe...
This is a great channel, please keep it up.
BTW do you know what the melting point of francium is?
Nice and clean video, informations, display...
Just if you have had include very common and interesting eutectic alloy gallinstan.
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
that was a good one, visually interesting too.
Come on, you did a good casting. I love the texture of the casted Wood's metal.
ur channel is awesome. very interesting
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.
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).
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...).
Can you upload another video? We love your videos...
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.
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
Holy shit dude you're awesome! Subbed!
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!).
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).
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 :)
Those smileys are great
Thanks for sharing!
Pure metallic indium is not toxic.
Compounds of indium can however be toxic (especially the water soluble indium (III) compounds).
Thank you!
I think my best video is yet to come. I always try to improve and being an amateur I learn something new with each video. I also get a lot of constructive feedback from my smart viewers that helps improve my next video :)
your videos are awesome :)
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.
Yes, toxicity is not the only problem with some of these metals. Cesium is a good example.
But I believe and hope that people spending 200+ $ on a cesium sample do their own research before buying ;)
Can you make metal spikes just like ice spikes? I think it would be really cool!
Hi. Tin is considered non-toxic - it is/was even used for covering the metal in tin cans for storing food.
So I wouldn't personally use a respirator while melting tin. I would on the other hand try not to inhale the fumes - it's never a good idea :)
But you must as a minimum use large and thick gloves and safety glasses (or even better a full face shield). Boiling water at 100 degrees C is bad - so imagine what ~250 degrees C molten tin will do if spilled or splashed on you...
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!
Here comes the metal meltdown, run for your lives! Can't stop the metal meltdown, no one survives!!!
