Stick around for the end!

[@YourBiggestFan123]

Prof. Woodward is explaing very good. Please more from him.

[@periodicvideos]

YourBiggestFan123 we'll try

[@ggdelgado]

lol the graduate student cleaned the professors mess, as usual.

[@obsidianwing]

Looks like a phoenix out of the flames when the aluminum hits the ground at 3:45

[@s3cr3tpassword]

chemistry: where adding water can cause fire

[@IsaiahMerryman]

I don't think you know how intriguing and educational your videos are, I thank you from the very bottom of my heart.

[@Skandalos]

"Ooh I made a mess. Hey get that extra over here to clean this shit up." There's the scientific process for you.

[@Chee7sAEpp]

i really like this guy. he explains super well!

[@ApolloWasReal]

When you talked about the unusual application of Me3Al and showed some rockets, I thought you were going to mention its use to ignite certain liquid fueled rockets. Because kerosene and liquid oxygen do not ignite on contact at room temperature, the F-1 engines on the first stage of the Saturn V moon rocket used a mixture of trimethyl boron and trimethyl aluminum in a "hypergolic cartridge" to ignite them when the fuel first flowed into the combustion chamber to meet the liquid oxygen. Of course the rockets you showed were solid fueled so they have other ignition systems. But that makes at least two very different applications of Me3Al in rocketry.

[@erictaylor5462]

It looks like it would make a good flame thrower. No need for a pilot light.

[@rogerdotlee]

Are we going to see more from Prof. Woodward?

[@rogerdotlee]

Please?

[@SecularMentat]

I do love some volatile chemistry, especially when they're explained. Also, organometallics are just cool.

[@RealDealHolyfield2099]

That is some beautiful camera work around 3:30. It doesn't get mentioned enough but Brady's high speed camera shots and graphics are top notch. He's a pro for sure.

[@KafshakTashtak]

Next to the Professor (with white hair, Sorry forgot his name) this guy is also very awesome.

[@nofacee94]

That guy is hilarious even if it is unintentional. "I can see the fear in your eyes"

[@crazytapper117]

Awesome video. Thank you to the guy that had to clean it! It is appreciated!

[@chopinbloc]

Phoenix at 3:46. Awesome!

[@tehlolzfactor]

I just found a new compound to use with my noble gas-filled flamethrower! Lol

[@keeperofthecheese]

pretty amazing how it doesnt carry on burning after it has struck the surface. It just kind of fizzles out.

[@Himark89]

pure magic called chemistry.

[@insertcomedy8505]

Could trymethalaluminium be used for a kicking flame thrower?

[@THEWATERENERGY1]

Nice to see tri-methyl-aluminium, have a complete other burning flame pattern compare to hydrogen flame in our earlier video,....!!

[@Forssa1]

Shit's on fire, yo.

[@Faxter313]

yay for cleaning it up! :D

[@RedTriangle53]

I think I need some trimethylaliminium now...

[@ShiroKage009]

No, no. You really don't. You just don't know that you don't.

[@Beer_Dad1975]

That and a water pistol purged with an inert gas and hey, an instant flame thrower!

[@RedTriangle53]

with a high-voltage electrode positioned at the aperture of the weapon, and voila! Lightning flame thrower!

[@zoeybartlett1767]

Can we get more of Simon? He's really good at speaking in front of the camera, and very thoughtful. He must be great as a lecturer.

[@unvergebeneid]

Holey mother of God! That was beautiful and frightening at the same time.

[@habibaghasafari2237]

amazing compound! thanks Brady.

[@Eliphas_Leary]

Brady, please make a video about what "metal" means, you know, with the electron cloud and the being amorphic and all the fascinating stuff.

[@hikuro14]

whoa that slow motion part was intense

[@eaturfeet653]

he was a spectacular teacher. i would love to have him as a professor and to see him in more videos

[@jochemvanl]

He's a great teacher!

[@erictaylor5462]

8:10 Well until the fire fighters arive and spray water on the fire!

[@zarathustra498]

Damn, wish we have enough funds to play around the lab like this

I get nervous when I see fire and Neil isn't around.

[@bonesmalin]

Brady, your videos are always awesome! :D Im also seriously enjoying the Hello Internet podcast. Thanks!

[@PodeCoet]

This guy is awesome!

[@Vicvines]

how do you collect a noble gas? You can't really make it from a reaction can you?

[@Acquavallo]

The graphite at the end is super cool!

[@elises.1588]

Fantastic presentation!

[@penfold1992]

why does the aluminium break bonds from carbon to seek out a bond with the oxygen? i did horrible at chemistry but what is the chemical reaction happening here? 2Al2(CH3)6 + 24(O2) --> 4(AlO3) + 6CO2 + 6C + 18H2 im sure there are other ways to create equal values so this is probably not the only outcome... maybe we would expect to see water too?

[@tomhubbard8510]

I'd love to see that plate through a polarising lense (which would show us the stresses in the glass)

[@jaffachef]

Love this new guy

[@IncandescentBlaze]

This is what it feels like when I pee

[@jimmylp2]

Good presentation

[@Kam_299]

What would happen if you used that in a spray bottle? Instant fireball?

[@AudioVideoAndMe]

I like this guy a lot, you guys should do more videos with him

[@Chaosdude341]

So, I fail to understand, by the explanation why the flame exists. If there are bonds being created, that requires energy, and should not create fire. Is it the bonds that are breaking from the carbon that gives it this energy? If so, shouldn't there be some cancellation of energy between the created and destroyed bonds?

[@Kabodanki]

And this is how pyromancy work in dark souls

[@Paulus783]

that is just so amazing!

[@BDRoland]

Fascinating!

[@BlobyFloby]

So you've solved the mystery of greek fire!

[@FishKungfu]

That was awesome!! 8:45 We throw safety to the wind when Brady shows up with his cameras. ;-p

[@maddhatter6551]

Love these videos. There great

[@TristanBomber]

Liquid fire? Cool.

[@brittanyrandall8843]

So Beautiful, my goodness!

Beautiful flames.

[@guiltyguildleader]

When he put the syring into i had the urge to put on my safety goggles.

[@rooiakkidis1]

Very interesting just did a chapter on organic chemistry and this is quite fascinating

[@marcuswhite4600]

Wholely entertaining

[@AMRosa10]

The slo-motion footage is really interesting. Several times the flames take on what look like a bird-shaped pattern... Producing Phoenixes in the Lab maybe?

[@xMr_Smiley]

Hmm with this type of reaction would it differ with other liquid gases not causing such an outburst in that? Or would it just make it worse?

[@12301231234]

Wait, did professor Woodward dip out afterwards without cleaning up?

[@designworksdw1949]

Can this be used in the production of carbon nanotubes?

[@MrGridStrom]

Later that day, he turned into flaming hot meteorman.

[@Dra9ontail2]

I always wonder what that giant apparatus in de back of the fumehood is... something to keep things out of contact with air, but does it have a name? Does anyone know?

[@lizzyvainne]

note to self: next time I go camping, bring some Trimethylaluminium to have the best camp fire ever

[@ChrisTheGregory]

As an American I know I'm supposed to prefer "try-meh-thihl-a-loo-men-um" but "try-mee-thile-al-yu-men-ee-um" sounds so much cooler.

[@Lardverse]

I'm curious, how do you build a particular compound?

[@diablo275754867862]

You are playing with fire

[@sirkowski]

My first thought during the first experiment was, shouldn't you remove the equipment? And, well...

[@41088avl01]

Isnt trimethel orthosilicate used to make aerogel. I wonder if this stuff can make aluminum based aerogel.

[@YodaWasSith]

Will someone who is smarter than me make the slow motion footage of him squirting fire into a screensaver and send me the download link?

[@jesutherland]

That's an interesting GoPro mount. What is that?

[@thewatcher753]

isnt Trimethylaluminium supposed to be Al(CH3)3 ?

[@Dudleymiddleton]

When I saw the thumbnail for this, what he created looked like an energy orb out of HL2 with a little black hole in it!

[@RaphaelBarboza77]

"I'm the one who knocks" Haha Impossible not to remember WW

[@superstrudel]

magic!

[@Core5]

I wonder if the graphite produced at the end has any special properties, such as containing carbon nano-tubes or graphine. It certainly appears fibrous, not at all like soot.

[@shreksthongg]

It's like peeing fire!

[@soapboychris]

Simon Woodward

[@nilswilling]

Awesome, but dangerous, too!

[@Acidictadpole]

Is Trimethylaluminium stable in solid form?

[@NToB36]

awesome

[@Domeiertho]

The flame falling look like meteorites crashing to the ground

[@xBris]

As a scientist, I can very well relate to the ending ^^

[@symbolxchannel]

Is it used in incendiary weapons?

[@RedInferno112]

Interesting... It must be Al2(CH3)6 and not Al(CH3)3 because it's an electron deficient compound, since it's covalent the Al only has 6 outer electrons, bit like in BF3.

[@SpikeTheSpiker]

If you pumped this into oil, would the lack of oxygen stop the rapid oxidation. (e.g. potassium in oil)

[@sync55]

best Molotov ever

[@MusikCassette]

8:41 how long were the nanotubes within that graphit?

[@Halo4978x]

What camera is used for the high speed shots?

[@pauladams1814]

could it be used in a flame thrower?

[@mrscottishelf]

i like this guy, he explains things everything, and thats good because i'm no scientist and never really know whats happening :p

[@vincenttony2417]

Why there is a hole after burning?

[@vectoredthrust5214]

I'm laughing like a madman at this. That's one chemical that needs to be respected!

[@TomyyY90]

as a graduate I know what he's going through ;)

[@Abinoka]

What types of jobs are there in the chemistry field? Do you require a PHD to get far in this field?

[@Sean_735]

Depends on your definition of far. Want to be a researcher at a university? Get a Master's degree, you'll eventually end up writing a large research paper at some point, and might be able to turn that into a PhD later in life. Want to do something _huge_ for modern chemistry? Get a PhD at a young age, and work fucking _hard_ all day every day researching something totally new with colleagues. The hardest part there might actually be finding that _something totally new_ to research.

[@scottmantooth8785]

how would this react with fluorine or cesium or both? ...my guess would be a rather unfriendly reaction not conducive to personal tranquility followed by expensive noises of things breaking or the aftermath of prolonged smoldering of materials not intended to ever display that particular reaction

[@albertarias745]

Is that Penta Valent carbon? is that a mistake or is that system set up so that it is a non classical carbo cation?

[@mystcalz2000]

talking about DABAL? its a typical lewis acid base adduct i think...
