Gold & Casio Watch - Periodic Table of Videos

[souske25]

i love neil

[Rannyfash]

can you do a video on fullerene depostion from carbon vapour?

[CocaineStyler]

lol why didnt you clip off the clock part?

[ricardotorress43]

they can try with electrochemestry depositation :) it's better i guess

[MrSuednym]

So, is the un-reactivity of gold due to the oddness of it's electron configuration? Being 5d10 6s1? Or does it have nothing to do with that. And wouldn't that make it more reactive?

[SEThatered]

The Professor doesn't need jewelry!

He has the most precious jewel: his Brain.

It sure is worth more than any precious metal could be!

[nibus126]

lol - and now no gold and no watches

[TheHPMan88]

why doesn't evry1 hav this done 2 their watches? small pieces of gold are not too expensive

[MrSuednym]

@TheHPMan88 The equipment is expensive though.

[ChaosButterfly8]

Au ๏ Is the REAL purpose of nuclear reactors to manufacture GOLD? ๏ Au $ $ $ Green Energy $ $ $ Cha-Ching Nuclear Power! $ $ $ Green Energy $ $ $

[Aviatorsmith]

@ChaosButterfly8 No. The cost of the reactions is higher than the market price of gold.

[scienceman64]

I think I'll still take the stainless Rolex my grandfather passed down to me. Although the gold is still cool.

[TGQuickStig]

Apart from the white haired weirdo is :)))

[FanTazTiCxD]

Gold is the best metal :D It's so amazing that it even display 1337 at 1:10 :P

[wtrmute]

Alchemists thought that gold was a more perfect form of matter (since it is "nobler", or harder to react), and that a process which could turn base lead into noble gold could likewise help men attain a similar perfection, both moral and physical. That was the ultimate goal of alchemy; the creation of gold would be simply an interesting side effect. At the end of the day, alchemy was as many parts theology as it was natural philosophy.

[BrootalMetalBanjo]

Why doesn't Neil ever talk? Is he also a Professor?

[stalkersas]

OMG i have a watch EXACTLY like that casio! have it since like 12-13 years ago and still has the original battery ^^ too bad the coating started to peel from the casing :(

[megajonathan96]

turn on translation and read 1:05 to 1:21

[luigi90900]

0:40 GOLDEN POPCORN!

[tmafkap]

About alchemy: the whole "turning cheap metals into precious ones" was meant as an allegory (can still be found in freemasonry, were the initiate has to put all metal down before entering the temple for the first time). The "metals" were the different properties of a persons character. Alchemists knew that most people misunderstood them, but that was a good way to find the few people that would understand what they really meant. And the misunderstanding gave birth to chemistry, didn't it?

[2camjohn]

@tmafkap Not for most Alchemists. No.

They really did think they could transform one metal in to another.

And why wouldnt they?

[tmafkap]

@2camjohn Obviously, you're the expert. Your sound reasoning cannot be refuted.

[1redneck15]

@Thewordupbro u are thinking of Chuck Norris

[aromchuen]

I like Neil. He's the silent type that never says anything in the videos but always there. Like a hero that will save the day when s*** hits the fans. :D

[CleverDjembe]

The band is actually stainless steel, not silver.

[Aviatorsmith]

@CleverDjembe The professor obviously knows that. He is talking about the colour of the watch.

[frohman101]

Great video, but can you make a video where you sputter gold on a surface, because I think it's a very interesting process as well to apply any kind of metal.

[Hashime777222]

Considering the work I've done with Barrik gold I could tell you so many trade secrets....but I had to sign a very large confidentiality agreement

[docatomics]

@Hashime777222 ...which will not be honourable should Barrik go tits up and be declaired insolvent under applicalbe corporate law or amaglamted into a new corp. without your consent, as that would breach the confidentiality agreement.

~so now , let us go in and examine Barrik's books and see if the stock blocks are as hollow as most every other public traded stock has become !

=Compile your notes into edutainment vids parch, we is going a digging for gold, as it is a survival thing to do !

[ginomw]

1:10 gold is 1337 :D

look left from Au

[TehConqueror]

6:37.....say that again?

[periodicvideos]

Win the watch seen in this video... details in the video description!

[godfearer62690]

Couldn't you just electroplate it?

[PhoenX19]

@godfearer62690 That's exactly what I tought too. Plating the watch by evaporating gold is quite cool though.

[thewordupbro]

Neil can create gold from lead using only his bare hands.

[chupachipmunk]

the rich man's F91-W

[Zepherus14]

1:06 and that's why gold is used in electronics and not the better choice of silver

[pepsibookcat]

Neil.  Need more Neil.

[killernat]

what happens when chemists get board

1 play with alklie mettals

2 play witch acids

3 gold plate something

[mahirharoon]

poor brady ,neil could have covered the screen

[ZorkFox]

Did the watch survive the boiling gold temperatures? That'd be a nice advertisement for Casio. ;)

[Intervene]

Nice stuff

[Ceevro]

Question; you've shown evaporation producing gold gas/condensation, but does arcing high voltage through gold produce monatomic gold powder?

[G3org3Master]

1337 anyone? 1:12

[ghuegel]

@G3org3Master 1337 K is the melting point of gold. Good to know.

[TheLaxOne]

@G3org3Master

It's the melting point of gold. LOL

[crabbygaz]

Some splendid hand waving from Prof today, he must have had three shredded wheat.

[vlvl21]

did not know that this method was possible...Cool.

[muhammadyousuf1]

holy crap evaporating metal

[Malithion2001]

So who has to buy Neil a new watch? Haha.

[norxcontacts]

This was a fun video :)

[thisusersuck]

can gold react with fluorine and chlorine ?

[Almontmarine]

you heat the Au to about 1337.33 degrees Celsius?

[pawningcity]

what camera do you use to film the videos? very nice quality . :D

[periodicvideos]

@pawningcity a Sony Z7

The periodicvideos blog has a lengthy discussion of all the technical filming kit we use (see the "bag of tricks" entry from March)... The blog is pretty easy to find from our main website.

[Fearfullways]

lul 1337

[engelteir]

is it a strong bond? or just a coating that would it wipe off? or rub off easily?

[okuma0kuma]

quaternion: thanks for the lesson

so remember people do not try the turn plastic coverings into gold before attempting to manufacture your fake rolex

[Garbimba1900]

Thank God there were no unfortunate "schmelting" accidents in this video

[GlobalWTF]

Cool experiment.

[asdasdasdasdasdas98]

maybe it could have been electro plated it, maybe would have had more success?



[periodicvideos]

@asdasdasdasdasdas98 maybe - but less fun than boiling gold! :)

[asdasdasdasdasdas98]

@periodicvideos na i just thought that was wasteful and inefficient, but thanx for the response. :-)

[tonyisgrendel]

@periodicvideos I'd really like to see a video on electroplating!

[japanesepoptart]

@asdasdasdasdasdas98

You could electroplate the metal parts of the watch, but you can electroplate the glass or plastic parts because they don't conduct electricity. (and as brady said, "It'd be less fun than boiling gold!")

[asdasdasdasdasdas98]

@japanesepoptart why would you want gold plating on the glass? it is a watch lol

[Erok9]

would electro-plating work better?

[Proph3tTroyer]

The gold on the window is epic... we should use that for window tinting.

[ghostthehostwithmost]

who wrote the subs here omg proffesor they need to learn some english ...lol

[MeLL1eJ]

Nice experiment :D

[guyontheend]

1 viewer tried this at home

[jakeweiq]

partly y alchemys r obsessed with turning lead into gold is due to the beliefs that they can obtain/discover the Philospher's stone, elixir of life or fountain of youth..etc through the process.. depending on which sources of information.. :P

[mewrox99]

you should have put some masking tape on the screen

[greeneyedgeek]

@mewrox99 that could have protected the screen from the gold vapor, but not from the radiation, it would've melted the tape AND the screen

[cadwaele]

Why is it evaporating on the watch and not in the inside of the box?

[XHeliosxXx]

u know very little about the science's but i love watching these video's

[FutureOfVideos]

Is there an electroplating video in this channel? :)

By the way i love this channel, i have been watching ever since i came across it.

This channel has significantly strengthened my ambition in becoming a chemist when i grow up :)

[greeneyedgeek]

@FutureOfVideos there's anotherchannel you might like: NurdRage, that guy does chemical experiments at a more advanced level.

[tjiddles25]

can you guys put a schematic of the machine used on-line?

cool video

[darrenc349]

whos that 1 guy who disliked this?

[Lioobayoyo]

@darrenc349 it's the owner of the casio.

[somorastik]

This is why I love periodicvideos!

Also by this vacuum evaporation, gold plated condenser microphone diaphragms are made!

Thanks

[DrAllan1]

Is the chamber you used the body of an old mass spectrometer?

[N3rd0fa11ag3s]

neil is awesomeee!!!!

[sphinxofthenewage]

amazing thanks for all this

[Jared2324]

we watch these vids everyday in ap chemistry =]

[TomMarAlem1987]

It is forbidden for Muslim males to wear Gold(Au). Women do not have such a prohibition. 

[TomMarAlem1987]

A notable use of gold: MONEY.

[HadeanAgent]

Whoa! Isaac Newton was ripped! O_O

[ytmoog]

@HadeanAgent

Newton was a bit of a crank in many ways, he was very into astrology and even predicted the end of the world.

Although he was smart enough not to give an actual date for the end :)

[CigarStudLasVegas]

I didnt think any cartier watches were CHEAP!!!

[codybfd]

neil is the shit

[eleph4nt]

@codybfd yeaa neil is badass

[Barnekkid]

I'm impressed with this "contraption" made by Neal. He seems to be a capable guy in his own right. Maybe he should do a video or two. 

[Endolaylith]

thanks for the scamming instructional video. :P

[BlowDevilUp]

Mercury and gold gives silver? WTF?

[RupertsCrystals]

@BlowDevilUp No, the mercury plates the gold, and makes it look silver.

[culwin]

Martyn should have done this video wearing a bunch of gold necklaces, like Mr. T

[CHESEPOWER]

There's better ways to gold plate than melting the gold, but nice video.

[slapthatmech]

wouldn't it be easier, cheaper, and more efficient to electroplate the watch?

[shaurz]

@ 1:13 - Gold is 1337!

[EvanLHarper]

Y'all should visit the Bank of England vaults.

[BabylonLynx]

lol, wasted a good casio watch... and a couple of grams of gold... it was fun to watch the process... but wut about using gold salts and electricity in a solution of gold salts to do the plating, would that work?

[Cyrathil]

@BabylonLynx That's the standard process using in commercial plating, if I am remembering correctly. This was probably a test for the machine turned into a video.

[doverlin]

If ever an inexpensive and efficient method were found to convert other elements to gold, what would central bankers hoard? ;-)

[EvanLHarper]

@doverlin hah, don't worry, it's all based on fiat-money these days, anyway. bits and bytes in a computer file, nothing more.

[doverlin]

@EvanLHarper I know, I know . . . just a pretty yellow metal. Yet central banks the world over own it and have been increasing their holdings for awhile. Fiat money requires faith by the users that it will retain value and central bankers are ready at a moments notice to switch over to a gold standard to retain control. So, what if an efficient method were found . . .

[EvanLHarper]

@doverlin It's clearly not accurate that "central bankers are ready at a moment's notice to switch over to a gold standard." There are absolutely no plans available to do this. There hasn't been a worldwide gold standard since the early 1930s (when it was a disaster, and contributed strongly to prolonging and deepening the Great Depression.) Even a return to something like the Bretton Woods system of fixed exchange rates would be wildly implausible, let alone an outright gold standard.

[doverlin]

@EvanLHarper Ever heard of SDRs? Special Drawing Rights made up of a basket of currencies. Discussions have been made to include gold in that basket. Also, the US dollar was the worlds reserve currency and IT was backed by gold until 1968 (I think) when Nixon took us off the gold standard. Since then, the money supply exploded exponentially (as it always does). So, we have been living on fiat money for 40 plus years . . . the typical lifespan of any fiat based currency.

[EvanLHarper]

@doverlin Central bankers have theoretically discussed the idea of including gold as a component of SDRs, a kind of international monetary unit. But that's nothing like having a plan to switch to a gold standard "at a moment's notice."

The post-1914 "gold standard" was a bit of a chimera, and it broke down completely after 1933. The gold window in the Bretton Woods system was basically a formality; the U.S. never made a credible commitment to maintain gold prices no matter what.

[EvanLHarper]

@Doverlin To take this discussion back to chemistry, I once heard a conspiracy theory that the central bank vaults are full of not gold bullion, but TUNGSTEN bullion, with only a thin layer of gold covering it by Chemical Vapour Deposition, the process depicted in this video. Tungsten has almost exactly the same density as gold, but it's much much harder, so the scheme wouldn't work. You could cast a gold outer shell around a tungsten core, though. (Remember the World Cup trophy video?) :-)

[doverlin]

@EvanLHarper Yes, I've heard the rumors of tungsten filled gold. No conclusive evidence has been forthcoming that I know of. The story indicates that the gold is cast around the tungsten, not plated which would be easily detectable. I think it behooves the US to do an audit of the gold reserves soon to verify the gold is there and that the purity is as stated in the records. Its been decades since the last audit.

[doverlin]

@EvanLHarper Q: As to the US commitment to a gold standard - no kidding. They cheated. More currency was issued than there was gold to back it up. France forced the issue when it sent naval warships to collect gold for their dollars. Any system where money is issued as debt is a ponzi scheme. When the scheme implodes, as it always does, gold is standing ready during the transition period. This same cycle has happened repeatedly through out a couple of thousand years of history.

[EvanLHarper]

@doverlin There's no empirical evidence of a "cycle" in which commodity money and fiat money alternate with each other. All money in human history was commodity money, up until 1914, after which there was an uneven transition to fiat money culminating in 1973. The current system of semi-independent central banks controlling the money supply, with flexible exchange rates, seems to be doing OK. Rumors of Tungsten-filled bullion in Fort Knox are spread by shady gold coin dealers talking their book.

[doverlin]

@EvanLHarper Like you said, this is a chemistry thread, but one last response. You stated: "All money in human history was commodity money, up until 1914 . . . "

One example: explain the split tally sticks in medieval England. Completely fiat and not commodity based. Another example: the Roman denarius was debased from almost pure silver to 2% silver - technically you could say it was commodity based, because it was made of metal. However, the face value was much less than the silver value.

[o0TheBeesKnees0o]

Fun video - thanks :)

[jacoman1234567]

Hahahahaha, no one of you guys had the idea of covering the window up? By the way, this process reminds me very much of something i studied a couple of years ago, a process called chemical vapor deposition...

[Kargoneth]

Does the vacuum help the gold boil by lowering the boiling point?

[jacoman1234567]

@Kargoneth That is correct!

[JimPrower]

heh...Is this a process typically used for gold plating on an industrial level? I always thought a lot of them had to do with electrolisys or some other chemical process.

[VanillaShoelace]

Admit it this video was one big product placement scheme to make some money.

[525047]

Plate something weird like a toothbrush. That would be a great gag.

[JaksProductions]

why do you leave fails in :( makes people look a bit dumb, saying the same exact thing 2 times :/

[periodicvideos]

@JaksProductions Dr Walsh is an excellent chemist at a world-class university.... I couldn't make him look "a bit dumb" if I tried.... However I think our videos have always been happy to show that scientists make mistakes and everything doesn't always go to plan!

None of us - including the chemists - want to change that by editing out everything that isn't perfect!

[JaksProductions]

@periodicvideos yeah, but I think he tought you will, thats why he said the same thing 2 times ;).

[peanutboy41]

does the professor say at 6:36 "and then you can't pull the shit off" ?

[risbolla]

@peanutboy41 "though you can polish it off" is what I heard.

[Nyphur]

@peanutboy41 He says "you can polish it off" :p. Interestingly, he talked about that in a video on mercury imalgam, which I watched just 10 minutes ago out of the blue :D

[SocomElite187]

@peanutboy41 polish

[Zeldakitteh]

@peanutboy41 Oh. I hear your version of it now too, sounds all wrong. D=

[h3wlett]

You smarties couldn't think to remove the electronic components first? sheesh.

Common sense is sparse these days.

[Kargoneth]

@h3wlett

Lol... that was my thoughts too.

[OttawaOldFart]

I would call that one a fail as far as a commercial way of gold plating. Does the watch even still work after being baked. lol

[gayglue]

Did anyone else notice the 1337 at 1:16? It was just meant to be..

[Nocturnox65]

Neal is like the Stig of periodic videos

[homousios]

I hope that you do put it on ebay. You should get a good price for it

[3eneboy]

it's be devastating if he dropped it :')

[andersvj]

Is Niel a chemist?

[SanguineBullet667]

inorganic chemistry RULES!

[schmidtbag]

lol niel looks so pissed

[Infloresence]

forgot to rate.... excellent as always....keep up good work etc...

[Infloresence]

The Professor has no bling, man I'm surprised...

[AguzSuiCaedere]

That watch has perish FOR SCIENCE!

[andersvj]

The professor should have mentioned the Bohr story from the Bohrium video :). Great video as always!

[genericmember1]

Look at the professor's hands from bout 2:20. It looks as though his hands are disconnected from his body as he moves them. Like he has his hands behind his back and someone form below the camera are sticking their hands up in front of him.

[EvanLHarper]

@genericmember1 It is taken with a relatively wide lens, and the camera is close to Dr. Poliakoff's face, so his hands appear unusually large. You can tell they're his hands because they gesture in exact time with his cadence of speech, and also because they shake slightly when he holds them still (which I have noticed in the other videos -- he must have some type of health condition.)

[genericmember1]

@EvanLHarper I know they're his hands, I was just commenting on how it appears as though they aren't his. It's quite a nice effect really.

[magicicle]

Neil is LAUGHING D:

[CoolMinty]

thank you Brady, for your sacrifice to bring us yet another interesting and educational video

[periodicvideos]

@CoolMinty a small price to pay...

[YdLeet]

Gold is 1337! :D

[Reqrezentin]

If only someone would put their hand in there instead of the watch ..

[sabaths1fan]

@Reqrezentin lol. Its a vacuum though you can't put your hand in it.

[NarutoSSj6]

i never could have gussed tthat gold was 1337!

[spasticpanda]

Will Brady be reimbursed for his loss?

[periodicvideos]

@spasticpanda I was thinking of putting it on ebay as periodicvideos memorabilia! ;)

[williamkendrick]

@periodicvideos i'd bid :)

[NAMLegolas]

@periodicvideos Do it!! ... Wait. I'm poor :(

[taofledermaus]

@periodicvideos you realize you guys could make a fortune, especially if you signed the various pieces you auction. Heck with this adsense stuff! T-shirts, hats?

[VulgarityDivine]

@periodicvideos Yes, it seems to be a good idea....I'm sure many people will pay good money considering it's REAL GOAL. :D

[TomMarAlem1987]

@periodicvideos Electrolisys seems the better option, because of the reduction in amount of waste.

[eutectics]

@periodicvideos you could sell the bricks that were burnt in the sodium and potassium vidios!

[Arnthorg]

@spasticpanda spoiler alert

[pacloro]

why when the einstein lookng guy always shakes his hands when he talks?,its funny lol

[douro20]

Timex at one time actually sold a watch with a Laco electric movement which had a solid 14K gold case.

[TheNemestrinus]

So you trashed a reasonably good watch... Why not take the mechanisms out of it first?

[temporaldisplacement]

Is there anything particularly special about the cunductivity of gold. ....my TV's AUX cable was especially advertised as a 'gold' coaxial cable with gold connectors. ......is that REALLY any better than a regular cable?

[CarlEldar]

@temporaldisplacement I believe it has very good conductivity. But that is just what I remember from school lol.

[temporaldisplacement]

@CarlEldar It seems so odd to make it ...if it doesn't do a better job as a cheaper material.....

[iseesquares]

@temporaldisplacement Nope gold doesn't change the quality of the picture or anything all it does it make the cables last longer since gold does not react well with oxygen.

[DeoMachina]

@temporaldisplacement No, not really. Silver is in fact a better conductor of electricity. But for coaxial cable, cheap copper will do just as good a job.

[iseesquares]

Make the professor some bling, im thinking a gold plated clock attached to some gold plated chains to wear around his neck!
