Stick around for the end!
Prof. Woodward is explaing very good. Please more from him.
YourBiggestFan123 we'll try
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
"Ooh I made a mess. Hey get that extra over here to clean this shit up."
There's the scientific process for you.
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.
i really like this guy. he explains super well!
It looks like it would make a good flame thrower. No need for a pilot light.
I don't think you know how intriguing and educational your videos are, I thank you from the very bottom of my heart.
I do love some volatile chemistry, especially when they're explained.
Also, organometallics are just cool.
Phoenix at 3:46. Awesome!
Next to the Professor (with white hair, Sorry forgot his name) this guy is also very awesome.
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.
Are we going to see more from Prof. Woodward?
Please?
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"
I just found a new compound to use with my noble gas-filled flamethrower! Lol
Nice to see tri-methyl-aluminium, have a complete other burning flame pattern compare to hydrogen flame in our earlier video,....!!
pretty amazing how it doesnt carry on burning after it has struck the surface. It just kind of fizzles out.
Awesome video.
Thank you to the guy that had to clean it! It is appreciated!
he was a spectacular teacher. i would love to have him as a professor and to see him in more videos
Brady, your videos are always awesome! :D Im also seriously enjoying the Hello Internet podcast. Thanks!
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.
Shit's on fire, yo.
amazing compound! thanks Brady.
Brady, please make a video about what "metal" means, you know, with the electron cloud and the being amorphic and all the fascinating stuff.
yay for cleaning it up! :D
whoa that slow motion part was intense
The graphite at the end is super cool!
Holey mother of God!
That was beautiful and frightening at the same time.
Damn, wish we have enough funds to play around the lab like this
This guy is awesome!
I like this guy a lot, you guys should do more videos with him
He's a great teacher!
Fantastic presentation!
8:10 Well until the fire fighters arive and spray water on the fire!
I think I need some trimethylaliminium now...
No, no. You really don't. You just don't know that you don't.
That and a water pistol purged with an inert gas and hey, an instant flame thrower!
with a high-voltage electrode positioned at the aperture of the weapon, and voila! Lightning flame thrower!
I'd love to see that plate through a polarising lense (which would show us the stresses in the glass)
This is what it feels like when I pee
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?
how do you collect a noble gas? You can't really make it from a reaction can you?
I get nervous when I see fire and Neil isn't around.
Good presentation
Love this new guy
that is just so amazing!
That was awesome!!
8:45 We throw safety to the wind when Brady shows up with his cameras. ;-p
Very interesting just did a chapter on organic chemistry and this is quite fascinating
Fascinating!
Love these videos. There great
Beautiful flames.
When he put the syring into i had the urge to put on my safety goggles.
note to self: next time I go camping, bring some Trimethylaluminium to have the best camp fire ever
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?
Can this be used in the production of carbon nanotubes?
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?
So Beautiful, my goodness!
Wholely entertaining
So you've solved the mystery of greek fire!
Liquid fire? Cool.
What would happen if you used that in a spray bottle? Instant fireball?
I'm curious, how do you build a particular compound?
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?
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?
Is it used in incendiary weapons?
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!
8:41 how long were the nanotubes within that graphit?
That's an interesting GoPro mount. What is that?
Later that day, he turned into flaming hot meteorman.
And this is how pyromancy work in dark souls
Simon Woodward
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.
Is Trimethylaluminium stable in solid form?
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.
You are playing with fire
What camera is used for the high speed shots?
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.
magic!
awesome
Awesome, but dangerous, too!
could it be used in a flame thrower?
"I'm the one who knocks" Haha
Impossible not to remember WW
Why there is a hole after burning?
As a scientist, I can very well relate to the ending ^^
Your camera movement makes me seasick. Cool stuff
Wait, did professor Woodward dip out afterwards without cleaning up?
Is that Penta Valent carbon? is that a mistake or is that system set up so that it is a non classical carbo cation?
talking about DABAL? its a typical lewis acid base adduct i think...
How does the syringe tip not melt??
The flame falling look like meteorites crashing to the ground
If you pumped this into oil, would the lack of oxygen stop the rapid oxidation. (e.g. potassium in oil)
You can see a phoenix at 3:46!
Yay for pyrophorics!
Does it react with water?
Yes. Wikipedia.de says is it explosive on contact with water.
I wonder how many Carbon NanoTubes you accidentally made at the end there... Haha!
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?
Neat!!!
there's a pee pee on my bag!
good job, keep the new guys coming
"A bit of faffing about..." Haha.
