Platinum - Periodic Table of Videos

[MrZythFx]

why did they go to the top of the mountain to do chemistry?

[IAINoodle]

I'd better get a model... from my bag of preschool toys... said the cotton-haired genius.

[dmytrocool]

Wait you have to run out nakid? they make shore you diffident steal platinum pieces? cant you just put them in your rectum?

[theflyingass]

@dmytrocool Full body search. Don't act shady, else they'll search in areas you don't want them to...

[gredangeo]

0:53 YO DAWG!! Is that jars inside jars? :)

[lohphat]

Could you explain what's happening on the platinum as a catalyst? Is it oxidizing and slowly evaporating like a tungsten filament would? Or is it just acting of a framework for the reaction and assisting in intermediate steps of the reaction and not losing mass?

[rev101ben]

Platinum is an effective cancer drug... how convenient. Good thing it's not expensive or anything...

[rich1051414]

@rev101ben 4:39 before people start inventing a new conspiracy theory lol

[illustriouschin]

Mine the asteroid belt for platinum, ya dummy.

[stardude692001]

@illustriouschin or bring one in to orbit earth because fuel isn't free.

but yes I have heard some estimates that say one or two large asteroids being mined in earth orbit could drop gold to the price of silver, silver to the price of copper and copper to the price of iron, or proximately.

[illustriouschin]

@stardude692001 You are right, fuel isn't free and neither is mining in space but the potential rewards from mining the asteroid belt would be absolutely incredible.

[stardude692001]

@illustriouschin

the problem is no one has the balls to do this, there would redoubtably be international outcries and unlike the LHC moving an asteroid could realistically kill millions of people, especially if we let NASA do it. On the other hand going to the asteroid belt would mean years of travel and radiation exposure that would make asbestos mining look like organic farming.

I say no guts no glory and Westerners certainly have no guts, maybe the Chinese will go for it.

[illustriouschin]

@stardude692001 All they have to do is convince investors how ridiculously profitable venturing into the rest of the universe could be.

[aphexteknol]

@aphexteknol - I guess I should watch the whole video before commenting,he talks about model airplane engines a mere 30 seconds after I submitted my comment... LOL

[aphexteknol]

Cool demonstration of the method used to operate model engines often used for radio control. The glow plugs used in the engines contain platinum, and the fuel is mostly methanol with some oil mixed in for lubrication. I always knew how it worked, but I had never seen a scientific demonstration performed like that.

[mrroboto8269]

now get some francium. have fun with that.

[Zolbat]

A fun fact you could even tell the professor: Because Platinum is used in car-catalysators, and some of it is lost over time, the roads contain more platinum on their surface than the ores and therefore scientists try making bacteria gather it for us from the roads

[mahela1993]

Loop at 4:06!! HAHAHA

[manmanguy]

Gold actually costs more than platinum in US dollars now. How very, very sad. Love these vids. I'm a total chem nerd.

[SuperTechieJ]

Shouldn't it be "Platinium?"

;)

[MazzixQ]

Green chemistry !!!

[falcoperegrinus82]

I think rappers should start wearing articles of clothing made of platinum mesh.

[Jordantow]

"even professors are modest" best comeback ever.

[hromi]

like the professors atom models :D they sound funny as well :D

[Hugh345678]

did anybody else notice the screensaver in the backround hoping between two monitors...

[AugustinusSextus]

@Hugh345678 cool!

[BarneySaysHi]

Periodicvideos makes science cool!

[rlewis1946]

Checking today's (January 31, 2012) spot price of Platinum ($1609 USD per once)... do you have a safe in your element's closet?

Always enjoy your videos!

[Tmaker197812]

oops 6.52 Jojo, where is my popcorn gun?))). If you don't know how to solve your problem follow someone who much more intelligent than you. No need to meet him personally - just look at his work.

[fpsfred77]

4:06 

[RaviPatel422]

Cool

[lukekk2]

3:45 "My Precious"??

[aatishhake]

@ 6:53 that what i used to do when i lost something and im in hurry ! lolzz

[Films4You]

@aatishhake Squeek

[seklay]

my favourite molecule is tetrahydrocannabinol ;>

lol

[adityagnet]

3:49 He's gonna steal it

[knockdoun]

0:32 omg dude that would be great in my bong....

[thedefiantrebel]

4:06

LOL

[JossJossJoss1]

but... if platinum is very unreactive then how does it catalyze reactions? That doesnt make sense. Of course, it does and I'm just not educated (at least in anything as useful and relevant as this). But I don't get it. Explanation, anyone?

[grimace365]

@JossJossJoss1 it does react to a few think such as the methanol atmosphere, where the molecules coming into contact with the platinum fibers,while heating the fibers, create the highly combustible vapors. so as it is very nonreactive it does react with some things.

[kght222]

@grimace365 it doesn't create the combustible vapors, methanol is combustible all by itself. it is a catalyst for the natural reaction between methanol vapors and oxygen, and the accelerates the breakdown of methanol so much that it gets very hot, and eventually it gets hot enough to ignite the methanol vapors (in the oxygen/nitrogen environment that is every day breathing air) but it itself doesn't really react, there is no platinumoxide or anything like that created.

[grimace365]

@kght222 hmmmm thats wat i get for not really listening to the video and just kinda assuming with a semi educational guess xD

[starofcctv94]

my very excentric chemistry proffesor died when I was there and when they looked through his desk they found a puddle of mercury and a platinum bar worth about £50000 that had been in his desk for about ten years unlocked.

[Cartmanpn]

how u add those timers in comments ???

[joertjoert]

@Cartmanpn just type them. 1:23 and such

[Cartmanpn]

damn how do you link those timers on chat ?? :(

[that0000guy]

nice tie ;D

[limefrog77]

These comments are so very different from either of the platinum videos from PTV that I have seen in the last month, I have gone right off them.

Not the comments themselves, I mean PTV. They seem to have falsified the comments. Highly unscientific. On this vid, there used to be a whole mess of comments on the squeeky toys... they are removed. Disturbing, and for no readily apparent reason. Not of any circumstance, but I wonder why.

[limpidd]

Best engine sound ever!

[MatiDoYouWantToParty]

The price of platinum (jewelry) is currently 1175USD per ounce.

[deccno]

@MatiDoYouWantToParty per ounce i saw 1668,75 USD.

[joeylawn36111]

Surprised to see that Gold is now about $200/oz more expensive than Platinum.

[EminidisMike]

This dude is holding a small piece of metal that costs more than his life counted in days.

[joeylawn36111]

@EminidisMike Not really : 1g Pt = ~ US $51.00.

[ricois3]

4:03, 4:05, 4:08, 4:08, 4:08

Plane in the Boooo! Nah! Nah! Nah!

[death4hiro]

"Well, even professors are modest" Couldn't stop laughing at that... no particular reason though

[samanbandana]

4:05 LOL XD bLLloooooo love this guy

[domo638]

i loved that pop =)

[Buddyb309]

I love your box of toys in the corner of your office.

[sleeptyper]

What happens if the platinum web dips into the liquid methanol ? KABOOM ? :D

[ABCDragonman35]

i like how when he was getting a model there were bottles of vodka on the right lol

[badhellman]

ireland rules

[lukas3606]

'you know if you want a real engine thfwuooooop' haha legend!

[CaIrOOMaLi]

2 people were gold atoms

[dragonology294]

What's that called again?.. Mr Jiggly wiggly i think..

[chemiealex]

oh my god, martin is unique!!! :D i think i should really study at the university of nottingham! ^^

[laputahayom]

2 people mined the tonne of ore.

[johnmacward]

When he said "methal or vapah" and "the cathalittic decomposition" I knew he was a Dubliner.

[damianpaz]

2:12

Cameraman: Why didn't you want to strip naked?

Professor: Well, even professors are modest.

GET OUT! LOL XD

[oomblikkies]

@damianpaz So, I suppose the Professor does not fancy the idea of a body search at airports? lol

[plrokster309]

I like how the his 'models' squeeked at 6:50

[1KevinsFamousChili1]

4:45 watch the screen saver on his computers it switches screens!!

[494c6f7665416c6578]

@1KevinsFamousChili1 It's a dual head setup. Nothing special.

[1KevinsFamousChili1]

@494c6f7665416c6578 ya i know i have see n those before but it took me by surprise and i just like them :P

[DrParkMD517]

Apart from the toys, lot at all that booze the professor has :)

[donnieval2]

i like how he says catalyst

[MinGophers]

I really appreciate all the time the Prof and the rest of the guys and girls put into this vid ^_^

[b1912313]

Ehhh...Platinum is decomposing the methanol, right? So....Methanol is decomposed into what? I mean, it becames something else after the decomposition...What is it?

[japanesepoptart]

@b1912313

It forms formaldehyde and hydrogen gas according to the equation CH3OH --> CH2O + H2

[LSchoenmakers]

@b1912313 the second reaction is 2 CH2O (g) + 4 O2 (g) ===> 2 CO2 (g) + 2 H2O (g). You can actually see how the water condenses against the wall of the flask right after you hear the *plop* sound, 3:13.

[LeonSK96]

4:00 einstein XD

[softilol]

3:51 hehe that guy is cool ^^

[everett1911]

haha, those squeaky molecules are adorable! <3

[WeatherManToBe]

BRRHGRHJGRJRGRJGRG

4:06

You're welcome.

[dljones33]

You always learn something new with the professor don't you!! 

[onthecuttingedge2005]

is there an effective catalyst for plain water?

[mofiorsIII]

press 6 for 7 grams of platinum

[pagani8]

repeatedly press 3:53

[macje89]

@pagani8 haha he said it's you



[Rbedwards94]

Even Professors are modest. You guys should make a t-shirt with that on it!

[ranggasapa]

i have a platinum... want sold

[madamerotten]

1 gram of platinum is worth US$63.17 right NOW.

[teknotoast]

4:05... keep clicking.

[UKNMajor]

@teknotoast is epic

[naragala01]

@teknotoast nice!!! :)

[Films4You]

@teknotoast Burrrru

[BlackMercurialVapor]

Watched the whole thing, Didn't hate it. lol

[alch3myau]

Something on Hungry Beast about the kilogram. ;p

[trogersgsu1]

Question: The reaction was just a reduction of methanol to formaldehyde; the combustion reaction was a result of heat created by the exothermic heat? So there was two separate reactions?

[chopppacalamari]

Great vid thanks guys, You might be able to tell me why platinum is invisible to a Pulse Induction Metal detector but not to a VLF  detector.

[Mastertim2006]

i wonder if you can use the professors hair as a catalyst aswell... it looks like it can do something

[jlmadill]

Who is this new guy?

[FacadeOfTruth]

i need Platinum fuel cells

[Silversun634]

This video proofs my point. Professors always have the best haircuts.

[Afrocanuk]

It will be good if you guys will start using math often to predict the outcome of chemical reactions; etc. For example using Logrithums to predict final concentrations. This will give students a higher appreciation for high school math & science. Chemistry is in itself LOTS of math.

[hanzithaking]

zippo has made a hand warmer that uses a platinum catalyst and zippo gas to burn and it work quite well actually :-)

[Streety101101]

if he keeps waving his hands im gonna trip out, this guys tripping me out... hahaha this guys off the chain! :D this is insane!

[jimkiller12]

4:04 lol at the airplane noise

[syedjaafar]

how much is that for 1 Gram? :D

[HAMZAZIAZIA]

If you think about it you can run a car on this? Since it doesnt decompose?

[omgLiam]

@HAMZAZIAZIA If only! A catalyst, by definition, is not used up in a reaction. However, that does not mean it isn't converted between one form to the next. It simply isn't possible, unfortunately. Practically, it'd be unbelievably expensive anyways as it's one of the rarest metals on the planet.

[DeFliegendeHollander]

Mhhh…

There is an error in this vidéo : the international prototype kilogram that is conservated in France (at the BIPM) in made of Platinum and Iridium, not Indium.

[9hello123]

@DeFliegendeHollander If you complain about someone making a typo, you better make sure you don't make two typos in the sentence that you're complaining in.

[DeFliegendeHollander]

@9hello123 : sorry for that, English isn't my mother language at all.

Ir and In are not the same element, it's all I wanted to say, typo or not.

[havoc873]

Not completely true about the toxicological effect of Cis-Pt. Cit-Pt can make Interstrand cross-link en intrastrand cross-link bonds with DNA. Of these two the interstrand cross-link is the most toxic to DNA. It will prevent DNA-replication and transcription.

It will also completely fuck up DNA repair, like homologous recombination, nucleotide excision repair and translesion synthesis.

[Megan64fan]

GREEN CHEMISTRY!!!!!!!!

[bennemann]

If you guys wanna SEE actual Platinum atoms (along with Rhodium), this video features tunneling microscope pictures of them.

/watch?v=O_PjMeukmzg

It's pretty cool.

[kiren941]

Does platinum react with a mixture of nitric acid and hydrochloric acid?

[thewiseowl]

@kiren941 Yes, platinum will dissolve in aqua regia.

[Scrap5000]

@kiren941 dunno, but gold does ;)

[primatepaul]

why has he got such wavey hands?

[SaintofKillers66]

@primatepaul he is performing karate on the invisible monsters of ignorance

[eveeveevien]

4:41 - 5:03 Look at the computers <:

[evnbrw]

@eveeveevien dual monitors :D way more productive

[rhyboy1]

hahaha! I loved him getting a model and they where all squeeky toys.

[zasx20]

the professor has lost it... "like a little airplay, BRUURURURUUR, if you want an engine!"

[shidoink]

i better get a model. eek squeek squeek. classic :)

[x69Crunchyx]

i thought iris people just drink beer and don't know any science

from futureama 

[sophieewohaa]

Is that platinum in your pocket or are you just pleased to see me?

[johnmacward]

Whoose yer man! No seriously, what's the Prof's name?

[shyrwinsteelsia]

@johnmacward Professor Martyn Poliakoff

[johnmacward]

@shyrwinsteelsia Actually, I mean the Irish chap.

[MelleB90]

best airplane sound EVER.

[peeweethe1st]

If you ever run out of money you can always open a small jewelry store ;)

[yoshinibble123]

What a nice sounding engine! :)

[cheesywhispers]

did you notice that the words on his computer behind him have the words going from screen to screen

[cheesywhispers]

this guy has the best hair ever haha:)

[Zantaer]

One gram of platinum is 34.39 British pounds or 53.88 USD

[Jadandlud]

@Zantaer ONE GRAM?!!! That's an arm and a leg. (Must study Alchemy to produce more platinum)

[wawabunny]

well, even proffessors are modestt

that was funny

[Frresh123]

This reaction can also be done with Ethanol. Is Platinum the only metal which can do this?

[gps93]

@Frresh123 No I did this in lab with a red hot pre-1982 copper penny.

[killernat]

could you use platinum as a catlist in a valveless pulsejet 

[Jadandlud]

@killernat Yes, if you configure it right. But the funding just to get enough platinum for one engine would be really expensive.

[jakeweiq]

6:49

professor stares for a while...

SERIOUS-MODE COMMERCED!

[VardanB92]

i bet he actually snatched it after the cam shut off 3:53

[masacatior]

bem que podiam colocar legenda nesses videos novos :)

[KlasnikovR]

Platinum ring = Happy hubby = Sad Wallet

[KlasnikovR]

Platinum ring = Happy hubby = Sad Wallet

[mewrox99]

Platinum coated electrodes are the best for making perchlorates!

[goomba45797]

Those 'models' are hilarious.

[dluo117]

Just one question...if in the UK people say aluminium, why don't they say platinium? :P

[boxer3main]

@dluo117 platininnium

[Doogeedoo12]

6:50 Oh my goodness. I was laughing so hard with the noise in the background as he dug. Oh Professor >u<

[grahamkeithtodd]

did not know about the anti cancer drug..thank you for showing this!

[yargh92]

looking at the stock market price for platinum... it looks like it tops about 1700 US an oz.

[Talic3]

Can someone tell me about the isotope Platinum-190?

[xMadSkillzx]

Does anybody know what the Methanol decomposes into? It looks like water vapour is formed and so the other would be hydrogen, so the heat produced is burning hydrogen right?

[colinstu]

That 1gram of platinum isn't that expensive... $47 one site said.

It's 1oz of platinum that is expensive :P ($1600)

[Draxis32]

The guy in the blue coat is Neil's son?!

[jjwhitty1]

"id better get a model" 6:51 i can just imagine his wardrobes at home with all the dog toys flying out when he opens it up :D

[putkettleonfilms]

"I'd better get a model". The quintessential nutty professor and his squeaking bag of teaching tools!

Love these videos - never knew chemistry could be such fun.

[megaverse]

Are we capable of making about any simple materials atoms by atoms ? I'm aware it cost too much and it's insane to think we could produce enough that way but i was wondering if we're capable of manipulating the atoms to make for example platinum molecules or if we just can't make it them stick together... I know we can create artificial gold and diamonds though it has nothing to do with the process i'm speaking above.
