  • 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.
    Link to the Hg-Tl pictures I use with written permission:
    www.periodictable.ru/081Tl/Tl_...
    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...

      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.

  • @brainiac75
    @brainiac75  Před 11 lety

    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!

      @@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.

    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).

    • @brainiac75
      @brainiac75  Před 10 lety +1

      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.

    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.

    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!

    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.

  • @brainiac75
    @brainiac75  Před 11 lety

    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.

    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.

    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.

    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 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

    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.

      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

    • @SkyWKing
      @SkyWKing Před 8 lety

      +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?

      +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.

    • @brainiac75
      @brainiac75  Před 7 lety

      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.

    Pure metallic indium is not toxic.

    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.

    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.

  • @brainiac75
    @brainiac75  Před 11 lety

    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 :)

      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.

    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...

  • @Walkingdeadman1991

    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.
