  • She actually says "actually" every four words or so. :P

  • Why is that lady on about a load of bullshit

  • Hey neat, i have a chunk of bismuth crystal like that one!

  • 3:45 if she likes shiny crystals, a thing to do is amke ur own with copper sulfate u can get at the lab and add water and when it evaporates u get crystals

  • Don't ask me why, but for a second I thought I was watching a salad fingers episode. And then 2:19 came.

    Awesome videos as always.

  • @AlphaKiloFive ffffff

  • BISMUTH MOTHERFUCKER

  • I love her passion for chemistry, she's so excited about it she can hardly contain her words. But she still comes off well spoken and knowledgeable. Lovely :)

  • I bet she owns a bunch of cats

  • Shes square and She likes shiny things!

  • you can have a small bite on the bismuth rod without serious poisoning and you drink them when you get a bad stomach, what a environmentally friendly metal! We should replace lead with bismuth

  • that woman has an amazing RACK of knowledge...

  • The Bismol in Pepto Bismal comes from the fact that it contains Bismuth. The formula for Pepto Bismal is C7H5BiO4. :)

  • I find it very difficult to concentrate on the crystal in her hands...

  • 0:36

    Pedo

  • Mmmm smart chicks are sexy.

  • Nothing wrong with being a magpie...

  • I just got a sample of bismuth for my collection, and so far, I have 13 of the 82 or so stable enough elements, I love your channel, keep up with the great videos

  • Damn, that stuff is the bismuth

  • @ki4hou and tutilitified Do you understand that this is exactly the kind of comment and attitude that creates anorexic, makeup plastered, surgically modified bitches? Debbie is smart enough to get this but a lot of girls are not and guys like you are a big part of why its hard to find a woman worth being with for keeps.

  • @tutilitified Damn, I always thought she was cute in a nerdy sorta way but it's ruined now lol. I never noticed that before.

  • @ki4hou I still like her in the nerdy cute way. Id just ask hr not to get emphatic enough to knit and crease her brow so much, but she still gets a nerd crush from me...the bigger problem than the forehead is the Au circle around her left ring finger

  • WHERE CAN I GET BISMUTH? IVE HEARD THAT ITS USED IN FISHING LUERS

  • @Mrbrandoncoolvids The easiest way to find it is in shotgun ammo. Remington makes a line of shotgun ammo called "No Tox" that has Bismuth shot instead of lead shot.

  • I've read that bismuth reacts with sulfur by turning black, so when you take Pepto Bismol before or after eating something with sulfur in it don't panic. On that note what foods are high in sulfur?

  • would an alloy with nickel be a good thing?

  • The lady in the video said that the half life of bismuth is more than the age of the Universe( somewhere in 2:00 ). But how could one observe bismuth decomposing if it didn't get to it's half life? (it didn't have time)

  • @NytzaYoz you can see how long it takes to undergo a 1/100 or some other smaller period of time of it's half life, and simply extrapolate it

  • @edkes123 Yeah...dumb me... I thought that there is a fixed lifespan that a Bismuth atom must have, but then I found out that atoms can fission 1 year after they were created, or 100 years, and the lifespan is kind of an average... (chem fail :D )

  • @NytzaYoz Hah that's fine. Happens to the best of us :)

  • Can somebody please explain how to make such a large and nice crystal? I just have a chunk of bismuth metal.

  • @Poleschs proboly with a current as well... certain fequencies

  • 0:29 Hahaha WoW! :D

  • NICE! Bismuth is actually radioactive. It's half-life is so long, OcarinaTycoon in the 2nd highest rated comment has the half-life. It's so long, that it's treated stable, and it has no radioactive daughter isotopes like U-238 for example. It decays to the toxic thallium-205, which is stable, but Bi-209 (100% natural in abundance) decays by alpha particle emission. The Tl-205 content is so miniscule in the decay of Bi-209. It also is the most diamagnetic element. It also has almost no toxicity.

  • bismuth= more pretty than gold

  • So, I just purchased some bismuth and it was beautiful... Then my brother broke it. Needless to say, I broke his Rubik's cube... I live in a nerdy family.

  • @Dirtboy101 So remake it, like they said in the beginning of this video. :) I'm sure there's guides all around on how to crystallize bismuth.

  • @OOZ662 There are, but my brother is kind of a dim whit. he'll probably try to heat it up and sold himself in the process.

  • nerdgasm

  • pritty this pritty that, of all these great videos you brilliant people upload there is only one thing that disturbs me. Why does every element that you can lay your eyes on has to be pretty and beautiful and what not? i want to see some evil, ugly, crappy, ominous elements too....

  • @teleman07 I totally agree with you! Every time he is so excited about the great looks of each element.

  • @teleman07 They just love they're job and say happy things about everything

  • @teleman07 The problem with showing the elements of which you speak, is that their laboritories do not have the equipment to house them. For example, watch the Plutonium video, and listen to the part where they talk about what kind of facility you need to house those types of elements. Also, the only elements that have been produced in quantities large enough to see, are elements 1-99, with the exception of actinium, protactinium, astatine, and to a lesser extent, francium.

  • @Crazynerd96 you completely misunderstood my comment mate. i believe this will clarify what i originally meant:

    the last sentence of the comment you replied should be read like this: " i want some elements that you can lay your eyes on should be called by you bad and evil and whatnot."

    but as you can see this sentence is demanding and negative, and i don't want to be trolling these good people's videos.

  • @teleman07

    plutoniumnvx0

  • @teleman07 Oh I see. I'm sorry. I misread it and misunderstood what you meant. I read that at a really late hour, and I was half asleep. Sorry for the mix up.

  • @teleman07 Yeah! I want to see bombs! I want to see hydrogenboosted nuclear bomb reactions, or at least have it explained as to why Castle Bravo caught the Manhattan Project researchers by surprise when the yield was 250-300% greater than what they estimated.

  • @teleman07 Because they truly love their jobs, that's why.

  • @teleman07 Might I direct you to the Tellurium or perhaps Selenium (when a selenium chemist gets on a bus, everyone else gets off) videos?

  • @teleman07 You mustn't be a chemist.

  • @teleman07 Our universe is a very pretty place :D

  • @teleman07

    ...H2S?

  • @SSJkiller Not an element.

  • @baggedandblown

    Obviously not. I was just trying to make a suggestion for a compound that would fit his description. Elemental sulfur would also fit, but they've already done a video on it, so I figured I'd state the next thing that came to my mind.

    If I was chemistry-ignorant enough to think H2S was an element, I doubt I'd have any interest in PeriodicVideos.

  • @teleman07 Antihydrogen should do it >:)

  • @teleman07 dewd sut up ur face!

  • Its also brittle. If he'd tried to bend that rod it would have snapped fairly quickly.

  • bismuth sounds like a pokemon

  • @CabalFreekSlayer A Wild Bismuth Appeared!

  • She likes shiny things!

  • she's married guys.

  • @onthecuttingedge2005 And cute.

  • @DeepAbsentia Very.

    

  • @onthecuttingedge2005 Hubby is a lucky guy. :P

  • bismuth has to be my very favourite element. i love how dence it is but lead took the glory, how beautiful it is in pyrotechnics, and how beautifully mathmatic looking in its crystal form, with alll its right angles and majestic luster.

  • upset stomach remedies, like PeptoBismol, use a salt of bismuth.

  • i have a bismuth rod which i found like when i was like 8 or 9 years old (i think it was a bismuth rod) i found it when i was walking home from the park near some place i think was under construction with all these moving trucks...

    i think

  • actualy bismuth is radioactive, just not very. but hold a geiger-muller counter next to a sample and it goes off more the background radiation can account for

  • @Danemarkofmalvern It's half life is : 19x10^18 y,that's more than a billion times the estimated age of the universe

  • @corvusatum Anything with a neutron is radioactive. even protons are suspected to decay, with half lives of 10^36 years, but (understandably) we havnt seen one do it yet

  • i dnt know why some people visit to dis video if they only want to see chicks.... dis iz not porn man juss listen what she iz saying..........

  • i dnt know why some people visit to dis video if they only want to see chicks.... dis iz not porn man juss listen what she iz saying..........

  • Damn she is so hot.

  • Bismuth is the most naturally diamagnetic element. I also think it was the coolest looking crystals.

  • umm bismuth is toxic and can cause kidney damage so you best wash you hand with soap and good!!!!!

  • Pepto Bismuth

  • at 2:45 lead is spelt wrong...

  • @ChRIs23696 it doesnt spell it, he just says it.

  • @scorpion779946 no the subtitles. its spelt led in them.

  • @ChRIs23696 oh. for some reason it didnt show that on my computer.

  • Actually I thought they discovered bismuth is slightly radioactive, with a very long half-life.

  • @FortNikitaBullion i'm tipping you posted that before you watched the whole video ;)

  • big ass titties

  • Blends well with the background

  • dont they use Gallium spoons for the practicle jokes?

  • @Oz6102 nope, it is cheaper to give someone soap that turns your hands black or a binocular that makes black circles around your eyes. they don't sell gallium spoons.

  • @vmelkon You mean the practical joke where you put the gallium spoon in Hot tea?

  • @Oz6102 I am not aware of that being a practical joke. There is a video on youtube where a guy shows a gallium spoon melting in hot tea and he says he made the spoon himself. If you find a joke shop that sells such spoons, let me know.

  • I want a Bismuth crystal o-o XD

  • i have bin looking EVERY WHERE! for a ring of Bismuth for my girlfriend...still looking

  • @miraclo3 ummm, that would be a pretty uncomfortably heavy ring ;)

  • @Adrenalinism look good on her tho =)

  • In-case you didn't know, Bismuth is used as indigestion medication. One we most know is Pepto Bismol.

  • Hello, very interesting thing I was wondering if bismuth may also serve as a magnetic shield between the two neodin magnet

    Thank you for your reply and wish you a nice day

  • @neja2402 Bizmuth is a diamagnetic material - so you can get it to levitate on a magnet with a proper setup.

    But i don't think it will "shield" anything.

    Most diamagnetic levitation setups that levitate magnets, have a magnet suspended above the diamagnetic material - it's influence acting THROUGH it. So no, it doesn't shield the magnets from one another.

    watch?v=jOaBnJpIRzM

    Here's the same setup but with Bismuth instead of Pyrolytic Carbon.

    watch?v=hnbfGaqNvjU

    watch?v=hyQztViPW1g#t=4m21s

  • Love at first site <3

  • ACTUALLY Bismuth IS radioactive. Its half life is 1.9 × 1019 years, over a billion times longer than the current estimated age of the universe, but TECHNICALLY it IS radioactive. Im not saying the professor is wrong, i know he probably knows this and he just said its not for the sake of simplicity but technically it is radioactive.

  • I'd like to grow my own bismuth crystal =)

  • @magicicle Pervert.

  • Comment removed

  • i bet its very heavy in the hand

  • I guess there's an error in english subs, at 2:45 Professor says "lead", not "led". I'm not a native speaker of English, so please correct me if I'm wrong.

  • @rageagainstthebath "lead" and "led" are both pronounced the same way, but yes, the substitle should say "lead".

  • hair off att 1:55

  • 1.9 x 10^19 = 190,000,000,000,000,000,000 years

    19 quintillion years

    Imagine existing that long as an inanimate object being melted and cooled and melted and cooled at the amusement of humans to watch you make cute shapes and pretty colors.

    What a boring life that would be.

    But bismuth IS cool.

  • bismuth isn't aware of itself

  • @Dopewackshit Yes, I know.

  • @OcarinaTycoon 1.9 x 10^19 = 19,000,000,000,000,000,000

  • @OcarinaTycoon 190 quintillion years, right?

  • @Evan2718281828 Yep. I said it, and then failed. You win.

    lol

  • how does it get that geometric texture i wonder?

  • @MegaZoneEXE Crystallisation.

    Like snow flakes.

  • The "lovely" at the end was kind of unneeded. x3

  • thats the nerdiest girl i ever saw !! hahaha , but i m a nerd too and i think she is in a way "cute"...anyway

  • very nice video! Thanks for sharing it people!  Bismuth rocks... my class room loves it

  • its heavyer then lead and is safer i can think of dozens of uses for this metal

  • I think bismuth should be investigated for high temperature diamagnetism coz it is currently it exhibits greatest diamagnetism at room temperature.

  • @aeroscope google: BSCCO

  • osmium is heavier than bismuth and it is no radio active or iridium or tungston

  • Actually, I have a chunk almost identical to the one they have in the video. You can buy them for 20-50 bucks a piece in the rocks and minerals store in banff

  • So if I were to drink a lot of Pepto Bismol without overdosing (if it was possible) for a REALLY long time, I'd glow in the dark? XD

  • Bismuth is a very important element. Without Bismuth we wouldn't have Pepto Bismol!

  • @Strideo1 NO ADS? OH NOES! GO BISMUTH!

  • Awesome! 5/5! I've always wondered about Bismuth... It does decay by Alpha decay, and is weakly radioactive. It's most stable and natural isotope is Bismuth-209, and therefore it will decay to Thallium-205 by 2.9x10^19, which is A VERY LONG Half-Life! It can be used to make crystals called Bismuth Germanate (BGO for short), which are used as scintillation crystals (colorless) , mainly to detect X-Rays, and will glow a bluish-green color under X-Radiation wavelengths. Keep Up The Good Work!

  • jesus christ calm down nerd. its a friggin video.

  • can we make bismuth crystal? if can,how? i want to know...

  • she seems familiar, where might have I seen her?

  • @vitruvian8807 Dr. Deborah Kays - she is in many of the Periodic Videos.

  • Alpha radiation is not very harmful outside the body - this is because it isn't penetrative enough to get through your skin. If you ate or inhaled the source you would be in a lot of trouble though.

    However, alpha radiation is actually made up of ionising particles - helium nuclei actually. This is not at all the same as radio waves and x-rays, which are both part of the electromagnetic spectrum, like light and gamma rays. And actually, x-rays are pretty harmful.

  • say that ten times fast

  • about alpha radiation, it will NEVER do anything to harm you. we come into contact with it every day in the form of xrays and radio signals. gamma radiation is the killer.

  • @tubbyhunter101 You're right, but also Beta Rays also are quite harmful and if you breath in radioactive particles that emit Alpha Rays then you can get cancer :(

  • Good grief what a load of bollocks tubbyhunter.

    Relative biological effectiveness:

    Alpha: 20

    Beta: 1.

    X-rays/Gamma: 1.

    Neutrons: 5-10 depending on energy.

    The reason alphas are so harmful is that they have such a short mean free path; which also makes them very easy to shield against unless you eat or inhale a source of alpha radiation.

    Gammas and xrays are the same form of electromagnetic radiation and there is a significant overlap in energy levels. There is no significant difference in RBE

  • I been taaaaakinngg care of Bismuth, everyday, been taking care of Bismuth in every single way...

  • yyay bachman turner overdrive

  • Have you ever went to a walk with it ?

    Kidding ;)

  • All this and they forgot PEPTOBISMOL!!!!!

    (bismuth subsalcilate) this metal is fantastically non-toxic.

  • @TheCaptainLulz the anti-beryllium? ;)

  • I don't know who made the italian subtitles, but a kilo of bismuth is 1000 grams, not 500. that's why it's called kilo

  • right. That's why it's called a "half-life," because that's how long half of it takes to decay. Half of a kilo is 500 grams.

  • the written subtitles in italian says:

    "the half-life is the needed time so that a kilo of bismuth, that is 500grams, decays in the son element etc etc"

    and that is wrong, since a kilo of bismuth is 1000g

  • maybe it means that 1 kg of Bismuth becomes 500g of BISMUTH after a while because half the number of bismuth atoms decay.

  • Lol i play the game Half Life Decay

  • I keep a chunk of bismuth by my bedside at all times, to get a healthy dose of alpha particles.

  • Alot of men can do that for you...........

  • You did watch the video? Bismuth is, for all intents and purpose, non-radioactive! You're going to be waiting a long time to get an appreciable amount of alpha particles.

  • Did YOU watch the video? I encourage you to watch the part from 1:00-1:11. I don't need very many alpha particles, just a few.

  • if anyone is worried about the toxicity of bismuth drink a capfull of peptoBISmol* and you will learn that its pretty safe. (*Bismuth subsalcilate)

  • God that chick looks intelligent!

  • men they talking of something else and u are looking at her boobies ur funny i had to see the video again to see what u talking about

  • So you can make Bismuth crystalione by just melting it?

  • u have to let it cool slowley and i think u have to pour some off while its solidifiyng, but im not sure u should look it up

  • kind of. you may get a few crystals, but in a vacuum you get the good ones.

  • a que pendejo estas

  • Actually a metastable element is a nuclear isomer, not a "very stable" radioactive element.

    97mTc, which is metastable, decays to 97Tc which is just radioactive; in the two nuclei the particles are arranged in the levels in different ways, one of them is very unstable.

  • lol, half of the people commenting this video say, that the woman is hot xD

  • science chicks are cool man

  • @dushiemcbag science chick + british accent = killer <3

  • can bismuth sheild or cloak a magnets magnetic field completly?

  • she is very cute

  • @DarkRain9000 yeeeah she is!

  • @DarkRain9000 eww

  • i like his hair :)

  • lol symbol: Bi

  • Who is the girl in this video ... she is HOT! ... my God, she is hot ....

    Jorgenskyt

  • The ranbow colors of that chunk of bismuth don't come though very clear on the video. But the lady holding it is pretty nice :-)

    1.9X10^19 -- what's that in a sample that size -- one decaying nucleus every second tuesday...?

  • Maybe they should declare Bismuth Decaying Nucleus Day a public holiday.

  • I think that Salicylate is related to compounds that come from the Willow Tree, like acetylsalicylic acid is aspirin, which is derived from Willow bark. And so, it works because bismuth is an antacid and the aspirin-like element is anti-inflammatory.

  • HOW TO MAKE BISMUTH CRYSTAL???

  • The scientist at around :30 kinda looks like one of those stereotypical mad scientists in my opinion...
