  • 2:38 Looking through carbon to see carbon XD

  • Fuck all the dope washed brains calling themselves artists, that do not allow their bullshit to be shown in a free science video!

    It's ridiculous.

  • @RoGeorgeRoGeorge True dat.

  • i thought mercury looked shiny and like liquid steel but here it looks like water. why?

  • The iron is in the shape of a penis. There, now you can move along with your lives.

  • Makes you think when you see a diamond which was once a person.

  • hey guys, i just got myself a freakin awesome car, but unfortunately you can't see it...

  • Au give me your gold watch, Ag it's only silver. Cu later.

  • Why I liked this: Iron.

  • Why not Radon in a light sign?

  • @Iniss132 Because Radon is radioactive.

  • isnt also caesium liquid in room temperature?

  • I saw somewhere where synthetic diamonds had a super low success rate, so what happens if your dead body diamond fails?

  • What's the point of "art" (and I use term quite wrongly) if there's no one to admire it!? Nothing more the than the bewildered mind of the obtuse artist!

  • That reflection of the iron looks really nice.

  • URANIUM!!!

  • i hate the gaywad who wouldnt allow is sculpture to be seen. He just wants money. i mean, go screw urself, d**kwad! no offense to u guys. i really like the channel.

  • @GTHaroFITBMX If you look closely, you can make out the shape reflected on the glass in two places. Oh, the IRONy :P

  • I have a few big pieces of uranium glass. It glows that green color when exposed to UV.

  • 1:40 - I stopped watching the video at this point and gave you a thumbs down.

    Science should be free and for free thinking individuals and this video sucks!

  • @jagara1 You do realized that was not the fault of the makers of the video but that of the artist? You punished periodicvideos for complying with the wishes of the gallery and the artist, no matter how ludicrous seeming. If they had shown it they may not have been able to publish this video at all because they are guests of that gallery, and so should respect the rules

  • @Iniss132 How is he/she blaming PV? He said: "Why make art if you don't allow others to see it?". He's not blaming periodicvideos, he is in fact, blaming the artist :P

  • Would it be a lie to say I don't like this guy because of how senseless he his?

  • 3:31 Who else was thinking of the music video The Postal Service - Such Great Heights when he mentioned silicon disks?

  • And here I was leaning in to read the small print on the signs in the uranium compounds exhibt in my local museum.

    As the rotating disc passed within about 8 inches of me.

    30cm is about a foot, so to safely observe the stuff I shouldn't have been that close.

    BUT! The actual chunk of depleted uranium had larger text so I could read it from several feet away. Still...would have been nice to know BEFORE I fried myself on it.

  • @Hoshimaru57 That said, supposedly your body can shed the radiation from a small amount of uranium in about 2 weeks, its been a week and the only unusual thing thats happened to me is getting a rash in my armpits.

    I now know that that is likely due to pottasium alum in the deodorant I was experimenting with, but it still hurts like hell.

  • Why the hell did he not show us Iron? Was it an iron d1ldo? huh. I'm kinda angry.

  • Great video, keep em coming

  • Uranium made me smile, When im 60 im gonna be a Green glowing Uranium ingot

  • the iron one does NOT look beautiful D:

  • Comment removed

  • How i am suppose to come fro Serbia to look at his "art". For as far as i am concerned, he could have made a turd like shape, out of iron. :D :P

  • You can use radon in the tubes, but you'll have to stand behind a thick leaded glass to watch it

  • Thats Boring!!!!!!

  • I have held mercury in my like 5 times.. It was only the size of pee but I don't think its that toxic because I'm still kickin it but when its a large amount like that.. I would assume so.

  • elemental murcury is not super toxic. I get annoyed that generally all people think that.

  • @Tossphate Elemental Mercury in it's liquid state is not toxic; however, it evaporates just like water does, and the mercuric vapors are extremely toxic if inhaled.

  • @matthew11174 Yes thats absolutely correct. I should have elaborated- what I meant was people tend to freek out at the thought of touching it but happilly roll it around in a dish in front of their face. Murcury does indeed have a vapour pressure (nothing like water), and at any one time a sample of murcury will be evaporating to produce toxic murcury vapour (tiny amounts mind you). I had an argument with an arrogant PhD student once about this. Everyone should experience touching murcury once.

  • boring

  • I CAN'T SEE THE IRON! WHAT A PITY!

  • totally pointless episode with the IRON, that was terrible

  • Soooo, he's pregnant?

  • Neon - one : Argon - naught

  • The sign says : in the interest of health and safety, we ask that all pregnant visitors maintain a 30 cm distance from this exhibit. Thank you. He says: I'm standing a bit away because there's a sign that says low level radiation source, please keep 30 cm away....but he was standing RIGHT NEXT to the radium exhibit (and if you have good eyes, there's sign that says the same thing...i wonder what that means?) O.O

  • why is the guy taking the piss with the iron..it was just silly

  • Naming bones "calcium", cobalt glass bottles "cobalt", and uranium glass "uranium" is not cool.

    People go to see the elements and they show them compounds. If I was a visitor, that would dissapoint me. And from the educational aspect, the laymen will memorize that bones=calcium, blue glass = cobalt and uranium glass = uranium, and that uranium glows. Lots of wrong memes on the loose.

    It's not like calcium, cobalt and uranium are so expensive or hard to show in elemental state.You can buy them.

  • what about osmium crystals? google image it, it's amazing

  • I thought I saw the outline of an anvil shaped object

  • The uranium is my favorite. I love radioactivity :)

  • I've never seen Iron :(

  • @rolingpingu yes you have. Just not pure iron.

  • @G3org3Master :P I was kiddin, u know?

  • @Roflsearcher

    The same reason banks have special vaults, shit's expensive.

  • What an interesting expo. wish I could visit. Would have liked to have seen the copper sculpture in full.

  • Silicon was cool to see. I've seen how they make those wafers and they actually produce a long rod of silicon and it looks like one of those snake fireworks that little kids light off but its obviously shiny and extremely massive.

  • Mercury is the best one because of the sulfur warning beaker.

  • That looks like a great exhibit.

  • Ugh. Elements are so boron.

  • @Eveoman so was that joke

  • @Eveoman dewhd nuh uh

  • you can see the iron from the reflection of the glass

  • The diamond made from the ashes of a dead person sounds a bit creepy.

  • @Tezcatlipoca73

    But a great piece of recycling!

  • OK. WTF with iron? O.o  They can show gold, but they can't show iron? LOL

  • ... Why make art if you don't allow others to see it? Hell of a British leading artist that guy must be.....

  • @NAMLegolas He learned from the RIAA

  • @NAMLegolas no, hes a d**kwad

  • Uranium

  • BISMUTH

    

  • Uranium is cool!

  • 7:00 Is he pregnant? :D

  • Really nice vid... except when he says "mercury is super-super toxic". Rubbish. We used to play with the stuff as kids, and I'm still around. No ill effects. (Except for the occassional psychotic episode.)

  • @jq747 Mercury is lethally toxic upon inhalation or ingestion. Playing with it in your hands will also cause problems as it can soak into the pores of your skin. I would imagine your life expectancy is reduced from doing so, but you're still alive because you didn't ingest it in any way.

    Go play with it some more, but make sure your gravestone says "Mercury is rubbish."

  • @RBIVscreamtherequiem No, it can't soak into the pores. That is a lie that circulates the Youtube. Mercury has a very high surface tension and does not soak skin or glass.

    It's the vapors that penetrate the skin (very poor method of exposure, compared to inhaling them) and if you have a HABIT of soaking your hands in mercury, you'll end up sick.

  • When I grow up I want to be a diamond

  • @razveck You may indeed become a diamond after you die.

  • This is probably the best video so far that you guys have made! It was really interesting :)

  • the man is keeps on talking...............it never ends......

    n i like the diamond story which is made in lab

    so charcol 2 diamond :P

  • @chemicalbombgang charcoal? He said a deceased person not a millions of year old tree. If people could be turned into charcoal, our energy problems would be solved!

  • @HouseJunkies666 People being largely of carbon as with most living beings

  • @HouseJunkies666 YA YA I KNOW HE IS A GUD PERSON

  • When I die, I want to make my ashes into a diamond.

  • nice

  • I wanna see all of them !!!

    BTW , I carry a keyring made out of radioactive tritium and phosphorus . It will glow for at least 20 years with no light source .

  • @cpana2001 No, those vials do not contain phosphorus. They contain a phosphor.

    Phosphorus is an element that glows in the dark when subjected to certain concentrations of oxygen (therefore it oxidizes and is being spent in the process), and a phosphor is a term that describes substances that glow in the dark for some reason.

    Tritium vials contain inert powders as phosphor. I expect it's some kind of a rare earth compound, or a mixture.

  • @endimion17 Tritium is actually a radioactive isotope of hydrogen. It glows from its own radioactivity. Unless I'm wrong, tritium decays somewhat faster than radium. But the radiation from tritium is far less dangerous than from radium.

    I would imagine phosphorous would interact somewhat vigorously with tritium though.

  • @CapPicard Pure,elemental tritium at standard pressure and temperature does not glow.It's almost no different than H-1. It might be possible that the solid/liquid tritium emits some visible glow like condensed radon does, but I doubt it.

    The glow from those keychains is radioluminescence of some compounds when struck by ionizing radiation.

    Phosphorous reacts with hydrogen (H, D or T) to form phosphine, and the reaction should not be not very spectacular (compare hydrogen reacting with N or As).

  • @endimion17 I stand corrected. My apologies.

  • big fan of cobalt. I'll need it for a hip some day :P

  • 1:36 iron reflection

  • The copper sculpture was my favorite. I also liked the sheer, clean elegance of the silicon disc.

  • Carbon was my favorite, by far. Uranium was the second best.

  • Sad they didn't show the iron one because I'm not going to be near Dublin any time soon being from Canada and all.

  • @mikemurko Pause it, you can see it in the glass like the top comment said...

  • platinum <3 i love platinum <3 , and platinum jewelery :D

  • YouTube needs an "interesting" reaction. This isn't incredible, this is science! (and some art)

  • I don't know if that is the case but, when you mix a little bit of uranium oxide in glass (turning it in uranium glass) it actually glows green under UV light.

    Maybe the piece on the exhibition is lit by a UV source.

  • I saw the reflection in the glass (of the iron). Pretty cool, thanks for showing it! :P

  • Uranium

  • Question for Brady (or anynone that knows the answer):

    What is Uranium glass made of? Like Glass? Made out of Silicon Oxide? Its made of Uranium oxide?(Strange cause Uranium oxides are black arent they?)

  • @Draxis32 : Uranium glass usually refer to glass that have been colored by adding uranium oxides, the glass seen in the video is probably a yellowish-green under normal light, but I suspect from the brilliant greenish light that it is fluorescing under UV light here. Uranium can be used in glass and glazes of many different colors, though little new glass or ceramics contain it..

  • @Ts6451 Oooh cause I thought we could make glass like, well you know, you probably have seen it, SiO2 when liquified becomes glass, Al2O3 also becomes a glass too, so does NaCl, Indium oxides and so many other metal oxides/salts that can be turned into glass so I thought maybe.

    But now i get the picture, thanks!

  • I think carbon and iron are the most beautiful- Carbon, as it what we and all known life are made of, and iron. Why iron? Because it can kill a star. And when it kills a start, it causes the creation of all the other elements seen.

  • I don't know who he is but apparently he's pregnant...

  • I think they were all equally beautiful -- I can't pick one favorite!

    My off-the-cuff choice for most beautiful element -- one that I didn't see -- is bismuth. They can grow really beautiful, interesting bismuth crystals that look like tiny rainbow architectural structures!

  • The uranium sculpture looks like Tiberium.

  • @Heartbreakhotel112 That is not an element?

  • @Zeldakitteh No it´s not.. but in C&C it is.

  • Wow! Love his obvious enthusiasm!

    My fave was the cobalt blue bottles.

    Can't say why, as I'm not sure myself.

    Perhaps it brought me back to my childhood when I used to dig the up from my backyard, and include them in my boyhood collection of string, marbles, butterflies, and interesting rocks.

  • I think the Uranium model is of Sizewell in Suffolk

  • i am guessing this is the iron art piece

    img.artknowledgenews. com/files2009b/Antony_Gormley_­Not_Yet_Titled. jpg

  • I wonder if there was any Plutonium there?... lol.

  • Cobalt rules

  • I saw the iron in the case's reflection :).

  • @PewPew4Yew What is worst ? the fact that u are proud because you saw a reflection or because you post a comment not knowing that this video can get into legal problems :D?

  • @PewPew4Yew It's a car, right?

  • @Roshkin I. . . Highly doubt a simple iron car would be considered art. . . But, no I don't really think so. . .

  • @PewPew4Yew Through a glass darkly.

  • Gold!!!!!!!!!!!!!!!!!!!!!!!!

  • That uranium glass sculpture actually is glowing.... uranium infused glass marbles can be easily found online and will glow green like that when in the presence of UV light.

  • The sign near the uranium piece (the one he didn't want to approach) reads "We ask that all pregnant visitors maintain a 30cm distance from this exhibit" :D

    So congratulations to him ^^

  • How do you unwind a bullet?

  • Beautiful exhibit! I especially love the deep blue color of the cobalt glass.

  • I watched the entire video just to see a piece of glass not glowing by some neat chemical reaction, but just plain old electricity. I want my 7.5 minutes back!

  • the iron sculpture can be found here: sciencegallery. c om/elements/iron-fe

  • @HaydenScheib Wow that is really underwhelming. Maybe the artist doesn't want it filmed because then everyone would know it sucked.

  • I know I read that the % of Calcium in bones is way lower than expected, anyone know a source for this? No way am i pulling out all my texts books to check right now

  • The iron sculpture ties with the Uranium sculpture, imo.

  • I WANT TO SEE THE IRON SCULPTURE!!!

  • @Zdawg2324 so go there and see it

  • You can see a picture of the iron exhibit on the science gallery's web site.

    Maybe they got permission to photograph exclusively or something.

    For all that build up the piece is a bit of a let down to me. Reading the description i felt like they were describing something else.

  • What kind of an artist doesn't want his work to be shown to more individuals than it otherwise would be? I would have told him that if he wants to be part of the exhibit, he should have an open and rational mind.

  • @Meiz79 yes.

    

  • Nifty.

  • DEFINITLY THE URANIUM GLASS WAS THE BEST !

  • i love chemicals.............usually the ones i like are illegal

  • You can see the reflection of the Iron

  • About the iron piece: FUCK YOU. Sorry, I'm not normally one to leave such comments, but come on. The artist can go screw himself.

  • @sooth15 And I think my favourite piece is the lead one. :)

  • @sooth15

    you can thank copyright laws and lawyers for that. they don't got a choice.

    yes most IP laws need to be reworked or completely thrown out. taking a picture of art isn't stealing or replication. anyone who says so is either greedy or they touched the Hg.

  • @sooth15 You can look at the reflection if you really want to see it (not very special, actually), but I agree with you about the artist.

  • @frankjohnson123 There's a link in the description that shows a small photo of the "piece" and I don't get what the big deal it. It's not that nice, and it's basically just a bunch of stacked rectangles. I wouldn't really classify it as "art" or "sculpture" either, since I highly doubt that he carved it by hand out of a chunk of iron.

  • I almost disliked this video because of that part at 7:29.

    Truthfully amazing. I can say no more.

  • It's funny how his Irish accent is almost indistinguishable from some American accents.

  • Great video!

  • science and art do not match together. what a waste (says a person who thinks most art is a waste of money and resources)

  • If you film the iron sculpture reflected in the silicon disc does it still count? You wouldn't be filming the iron, you'd be filming the silicon! ;)

  • Platinum.

  • Check the reflection of the iron statue

  • this guy reminds me of Erik Beck from Indy Mogul

  • if you can't photograph it, why would you tease us like that?

  • if the lead piece is made from a bullet then it contains some Antimony (SB). anywhere from 1%-7% of it is antimony.

  • As much as I like the way the uranium sculpture is lit (and the "think of the argon exhibit as 'Ceci n'est pas une pipe' for somebody more into science than pure art"), the thing that brings the mercury exhibit over the top is the sulfur warning mechanism.

  • Pb is my favourite element so by default the lead piece is my favourite.

  • If you look hard enough, you can see the iron sculpture a little reflecting in the glass when he has his hand in front of it.

  • YOu can see the reflection of the Iron when he puts his hand in front of it. The reflection is towards the back of the container, and hopefully no one is getting sued, although I could use the money

  • How dangerous would the uranium glass sculpture be if you didn't stand 30cm away from it?

  • @JackDigital Not very dangerous at all. The 30cm is just a precaution.

  • Diamond from a person's ashes? Aren't ashes only the remaining salts and inorganic compounds from the body when all the carbon is burnt?

  • @0Sebek0 The bones remain after cremation, they chop them up into a fine powder, which, along with real ash, is what people call 'the ashes'.

  • @eltotoX

    not really, at high enough temperatures the bones will disappear. If a body is properly cremated you only get ashes, maybe pieces of teeth, kidney stones, and any metal implants. no bones. But in the past i think it did often happen that bones remained.

  • My goodness, they're all fabulous!

    

  • im a fan or the radium because it is interesting to think about how people saw the world before the present, but more interesting to think how our future generations will look at us

  • 1:35 made me lol

  • My favorite is the Uranium.

  • You bastards! I'm 2800 kilometers away from Dublin, I have no chances to see this piece of iron! :P Nice video, btw!

  • Among the beautiful elements in an artistic sense must be bismuth as hopper crystals. Bi is reasonably safe to handle as well so you can display them at home.

  • 1:35 Reflection fail :) 

  • what about the Fluorine?
