[@GateCrasherVI]

=D The Professor is so nice! It's neat seeing someone so traditionally educated explaining "Give me a moment, I'm making a KZbin video" =) Thank you! We love your videos!

[@netele]

thumbed up for that professor phone call

[@Ballacha]

4:23 this should totally be a pokemon

[@beeble2003]

Great to see that Professor Poliakoff had his professor hair even before he was a professor. :-)

[@Scrap5000]

I can't express in words how awesome this professor is!

[@ubhelbr]

Vileplume!

[@Scy]

That was sublime.

[@punishedexistence]

I remember making ferrocene and acetylferrocene in chem lab, man I miss those days, if I lived somewhere important, I could be putting those skills to use. But man the memories...God I love these videos!! And yes, the Professor shares a likeness I do; finding chemical structures in the mundane, for example, a hex nut is a perfect example of benzene, and chickenwire is an excellent representation of a graphene sheet. Yes, I can say with a passion, I love chemistry, always have, always will!

[@Hail_Fall]

The funny thing is, when he pulled out the two dog toys and the yellow ball I immediately thought that the structure was probably like a sandwich.

[@tehgendo]

if there is any pokemon fans out there, this video helped me learned something that might be clever on game freaks part! ferroseed is metal grass type, organic and inorganic. ferrocene established the field of Organometallic chemistry which concerns the chemistry of compounds where you have carbon boned directly to a metal, organic and inorganic! of course i could be looking way into this.....

[@InceptionSolver1]

haha I just got done synthesizing monoacetylferrocene and 1,1'-diacetylferrocene in organic lab!

[@b4ux1t3-tech]

What I want to know is who called? :)

[@vwoxy1]

5:20 in the captions: "org and the metallic chemistry" That would be quite an unusual band name...

[@thejumperkin]

Normally Brady's videos are 100% fluid and beautifully informative but I really fail to understand why it suddenly cuts to Ferrocene sublimation..? Can someone explain this? I was expecting to see an "extra footage" to shed some light on the matter but I see no such video.. :(

[@KjKase]

heh, this just shows I really know nothing about chemistry. Loved it!

[@NickAlexeev]

Cyclopentadienyl (anion) is aromatic like benzene.

[@pikuorguk]

From watching these videos I have mostly learnt that dog toys are modelled on various molecules. I wonder if there's some frustrated chemist in a dog-toy design company somewhere.

[@cleetric]

i worked with ferrocene in graduate school. we bonded two molecules of anthracene to the rings. the electro-dynamics of that compound were very cool. very very interesting molecule!

[@AlibifortheAfterlife]

Anyone notice how Martyn gets really excited over the strangest things?

[@moncef0147]

that's actually why i clicked on this video, i was watching a video from periodictable channel and they were talking about perfumes, and then i saw vileplume and i thought it had something to do with it. it reminded me of that pokemon episode about perfumes...

[@tumest]

During my summer undergrad lab we got to sublime ferrocene very slowly to make nice big flaky orange ferrocene crystals.

[@seahawk124]

Oh my god the hair in the photo! Is that a sublimation reaction too?

[@AlphaNumeric123]

Its the additional pi electrons, as opposed to the additional carbon, that are more fundamentally responsible for the stability.

[@Kabukita]

Really interesting... there's so much to know about chemistry that I never would have imagined.

[@douro20]

Safety, and the fact that it heats very evenly. An open flame in this case can produce a grave fire risk.

[@LadyTink]

6:40 I love that visual representation of heat :D

[@Spiray]

5:49 Young Professor has awesome hair, too. COOL!

[@TnEEn]

2:28 You gotta love this guy! :D

[@VivecAlmsivi]

Please never stop making cool videos like this

[@BigNWide]

Thanks. Any chance you'll be doing one soon on ammonia? Or a video on one of the standard pH indicators and its color-change chemistry? It would be great to have those for teaching, to supplement the one you did on HCl.

[@Rib640]

Wow... that lab is huge!

[@YamiPoyo]

Wow, how old is the professor? I love the videos hope to see many more.

[@patrickssj6]

"because I am making a video" - Haha great :D

[@nwtipton]

if it was energized in space and turned to gas form, then cooled down but there was nothing for it to cling to, would it crystallize to itself somehow? Or stay a gas forever until the first impurity? Or maybe a simpler way of asking is, do crystals always have to have an impurity to start the crystallization process? Your videos are the best, thank you all!

[@MephistoRolling]

why is it darker at the top? is it burning? or is that to do with the new crystals? I love your videos, making science interesting and fun for everyone!

[@Cellogamer]

@Serostern It can be adjusted for making the flame hotter or cooler, however, I still believe that the flame will heat the ferrocene too much to before it loses enough energy and deposits into it's solid form again.

[@hanzithaking]

i so want to come and study on your university it is awesome !

[@Mrmayhembsc]

thanks for help revising for my chemistry degree

[@LeetMath]

the piano stool is so cute!

[@M4Ho2]

Guys, try to turn on the captions and watch the video with reading them, it is hilarious.

[@Cellogamer]

@Serostern I think because that way the molecule can depose quickly enough. A Bunsen burner may keep the molecule too hot for too long.

[@douro20]

@verybiggun Yes, but it was the discovery of metallocenes like this which really made the world of chemistry excited about organometallic chemistry.

[@M1ST3RHYDE]

I think it was great that you left the fone call in the video:).

[@ImAmWatching]

It is interesting molecules like this that have made me take chemistry for sixth form.

[@skadogg22]

wow what a beautiful lab!

[@GetMeThere1]

Leaves me wondering what are the specific physico-chemical properpites of molecules which prevents them from being liquids.

[@rosePetrichor]

The 'piano stool' molecule looks like a Vileplume from Pokemon!

[@verybiggun]

Very informative viedo :) What about Nickel Carbonyl....surely that is an organometallic compound that was discovered before ferrocene?

[@bcisbwbdkvivjebeorogidb]

"This is a heat gun... [It's] very good at heating things." How stunningly insightful.

[@shouryuuken100]

@leungclj Chemists never use (bunsen) burners in labs because there are too many solvents that are highly flammable - chemists try to be as safety conscious as possible. You can get the same effect with blow guns or 'hotplates' as you would with a burner anyway

[@majornewb]

I have one of those wooden things with the smiley face!! They're used to massage your muscles haha

[@Desmaad]

I find this funny considering organometallic compounds have been known before ferrocene, including the infamous tetraethyl lead.

[@Rigo0Jancsi]

I would like to give thumbs up (as usual for these great videos!), but it's been deactivated. So in written form: thumbs up!

[@douro20]

Yes, cyclopentadiene is incredibly unstable. Its flashpoint is 25 degrees Celsius.

[@McPrfctday]

I wonder what company made those toys? They'd probably be tickled to see this :D

[@Serostern]

@Cellogamer But a bunsen burner can be adjusted for that reason? I don't really know =P

[@lydz121]

LOVE THE TIE =D!!

[@MasteroftheDead]

I love your videos

[@Kabukita]

and only 5 people left comments about his hair in moscow! take a closer look... it made me and my family laugh out loud.

[@SophieNgJingYi]

1:43 "....that in the early 1950s a chemist called..ring.... " lol

[@Benivator2]

why use a heat gun and not a Bunsen burner???

[@Gauldan]

i like the editing

[@bbsonjohn]

6:20 are the powder "bubbling"?

[@BobStinkfulla]

@TheBetterGame Because heat guns are safter, generally most labs try to avoid open flames these days.

[@esnevip]

I'll bet he has a little playroom full of them, where he does his thinking.

[@Serostern]

Why a heatgun instead of a bunsen burner?

[@padeanyo]

Why is it insoluble in water?

[@xKevTiffx]

Can I...can I call you back in a littl'while? I'm just making a video...bye! Hahah.

[@Bimm3rcc]

We want more organic molecules =D.. How about some carbohydrates? I think sugars are one of the most hard things to study, and would help many if periodicvideos gave a hand =).. Sincerely, a chemical engineering student.

[@TomMarAlem1987]

Organo-metalic chemistry example: Hemeoglobin in the red blood cells.

[@padime]

Great as always :D.

[@TheBetterGame]

why use the heat gun, why not a burner? If this is going to sublimate, it's not going to burn, is it?

[@philipschloesser]

everything can sublimate under the right conditions, as long as it doesn't decompose

[@coolragazzo94]

thank you professor for putting us first!

[@tcdahn7]

thinking about c5h5 and palladium

[@raquer10101]

5:58 Youger days, and still... DAT HAIR.

[@QuantumTap]

How has this not been dubbed the tie fighter of chemistry

[@acash93]

The piano stool is more of a vileplume.

[@SaznizamSazmee]

I think the Professor spend a lot of his free time in the pet shop

[@isaactanyl]

@ImAmWatching exactly.

[@chrisdowling1997]

His son had a frog which now lives in the university and he has to go and buy food for it, it's in one of the videos

[@Incuby]

@doctorlady4637 i made synthesize it too last semester ;) But what happend if u add nitric acid to it?

[@mrdistraction]

4:20 smiley face :D

[@JPZ16974]

niobium seems to be a very optimistic "chipper" element :o)

[@SatansAshtray]

I once made it :P it smelled very nasty though ^^

[@toddoroi4947]

What about C5H5+?

[@GetMeThere1]

Wow! Very dramatic first 30 seconds! I went from thinking the Professor had a fetish for chewing dog toys, to briefly thinking he had an interest in witchcraft.

[@shadowjsw]

5:52 , did the professor ever NOT have scientist hair?

[@bemanos12345]

nice video

[@mertaksac9718]

I love the absurd veriety of objects the prof uses as models

[@leungclj]

wondering why use a heat gun but not a burner?... :\

[@Chrnan6710]

2:50 Is that a Cadbury Creme Egg below the computer?

[@bennemann]

Someone get the professor a pair of psychodelic glasses!

[@ultrahenk]

Somehow I found this video absolutely hilarious.

[@akashashen]

Normally, I can remain fairly adult about the hair, but to see it in the earliest stages of its life was almost shocking. What's the earliest shot of that hair that exists?

[@Fleshcut]

I had to make Ferrocen for my studies :3 Sadly it wasnt really fun...

[@stephanied2604]

The dog toy looks like a zeolite too!!

[@Queenmania2007]

That phone call...the professor is adorable!

[@fullheavy]

nice tie

[@douro20]

@TheChopstixofdoom It's a representation of the cation of cyclopentadiene (C5H5-)
