Holey Experiment - Periodic Table of Videos 

Stick around for the end!

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

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

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

chemistry: where adding water can cause fire

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.

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

Are we going to see more from Prof. Woodward?

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

i really like this guy. he explains super well!

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

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.

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

Phoenix at 3:46. Awesome!

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

Could trymethalaluminium be used for a kicking flame thrower?

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

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

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

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

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

pure magic called chemistry.

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.

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

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

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

Shit's on fire, yo.

This is what it feels like when I pee

whoa that slow motion part was intense

I think I need some trimethylaliminium now...

amazing compound! thanks Brady.

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?

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

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

Fantastic presentation!

The graphite at the end is super cool!

This guy is awesome!

yay for cleaning it up! :D

He's a great teacher!

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

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

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

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

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

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

Love this new guy

Good presentation

And this is how pyromancy work in dark souls

that is just so amazing!

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

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

Fascinating!

Love these videos. There great

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

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?

Later that day, he turned into flaming hot meteorman.

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.

Wholely entertaining

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

Beautiful flames.

So you've solved the mystery of greek fire!

So Beautiful, my goodness!

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?

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?

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?

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!

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.

isnt Trimethylaluminium supposed to be Al(CH3)3 ?

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

Can this be used in the production of carbon nanotubes?

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

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

Liquid fire? Cool.

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.

Is it used in incendiary weapons?

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

The flame falling look like meteorites crashing to the ground

What camera is used for the high speed shots?

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?

Simon Woodward

I wonder how many Carbon NanoTubes you accidentally made at the end there... Haha!

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

Awesome, but dangerous, too!

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

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

magic!

there's a pee pee on my bag! good job, keep the new guys coming

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

So I guess if you drink this stuff you'r probably die. But you'd also have the most epic pee.

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

You are playing with fire

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

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

It's like peeing fire!

awesome

"A bit of faffing about..." Haha.

Is Trimethylaluminium stable in solid form?

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

Neat!!!

could it be used in a flame thrower?
