Would most likely break apart faster and you would have a pile of oxide dust. The reaction would go faster, probably able to be seen without speeding up, but you would lose structural integrity gained by a slower rate of growth.
BOOM. Seriously though, I'd be really curious to see just how fast this reaction would occur in a pure oxygen environment and if the aluminium oxide would continue to be structurally stable under increased growth conditions.
I think when someone commented for towers colliding, they might've meant using two plates at 45-ish° angles towards each other so they would grow into or through each other
The change in color is because aluminum oxide growing slower and denser(less spongy) like the rings of a tree, in winter they grow slower but make harder wood. So because they are packed tighter together they appear darker.
I don't think it's so much a case of the fibres being packed tighter together, but rather that the individual fibres have grown thicker - this would also explain why that region seemed to hold together better when he pulled it apart 4 about minutes into the video
I suspect the reason the top towers collapse first is relatively simple: Gravity. The fibers have slightly better tensional strength(hanging as a loosely connected group) than compressional strength(growing upward and increasingly fighting its own weight)
Could the darker grey during the vacuum be due to the lower pressure causing more of the mercury to evaporate, and it gets trapped in the fibres? This would explain why the pure vacuum makes it darker, whereas it looks much lighter in the nitrogen environment.
I found it wonderful too; Mundane seemed so out of order; but he says he was probably oer it; I expected a circle of dots though which would have been wonderful.
One of the things I like best about your videos is that you explain everything clearly and your process of determining which variables are influencing the outcomes. You state your hypothesis and your methods very clearly and your conclusions are pretty careful and scientifically thought out.
Two things I would like to see...one is I see is already mentioned...doing it is an oxygen-rich environment. The other one I would like to see is what would happen if it were in crunched up foil (most likely dip the foil in the acid, then put a few drops in, then crunch the foil up)
Creepiest looking experiments ever! That perfectly smooth motion of the growth is something you normally only see courtesy of digital effects (e.g. on a ghost rising). Thanks for revisiting this.
It wouldn't work too well. In more than one way. Let's assume you mean something around the size of a grain of sand. Each granule is already coated with a layer of aluminum oxide from just existing in an oxygenated environment. I'm not sure exactly how the mercury gets more un-coated aluminum to amalgamate (does it move underneath the oxide layer?), but I'll guess it wouldn't work so well having to remove the oxide coating from each and EVERY single grain of aluminum. And, since a pile of sand sized particles isn't held together to begin with, you'll end up with a pile of oxide powder and no real structure to look at.
You need to be a teacher. Kids would pay attention to you. You have an excellent way of talking and explaining things. Very easy to understand. Kids today need someone like you.
NileRed: Many years ago, I was told to use mercury on my silver coins to shine them up. Worked for a few hours, then very dull. Looked further and found I should wrap them in aluminum foil. Both the coin and foil had exothermic reactions and the foil turned to ash as per your video. Would the silver have had any additional effect in this process?
2:14 I theorized that since the amount of oxygen is reduced, the reaction was put in a state where, in order to continue, needed to use more mercury. And so the color was a darker shade because more mercury was used than oxygen.
How about doing it underwater? Would the buoyant force on the amalgam possibly make the towers be able to get bigger? Maybe salt water would work better.
Well, you see in the video that it can still work under close to a vacuum. I'm sure more oxygen can dissolve in water than there was in the vacuum chamber.
If you put aluminum in a caustic solution of sodium hydroxide various things happen but, long story short the aluminum will pull the oxygen out of the H2O itself! Not really an over all efficient way to do so but it is one way to generate hydrogen for stuff.
the aluminum would react with water instead of oxygen, and I don't know if aluminum hydroxide would form the same sort of strands that aluminum oxide does
I'm thinking that the darker grey is formed somewhat like how rings on a tree form. A slower growing tree will have a denser composition than a fast growing tree, as the amount of material added is smaller and more compacted. When the aluminum is growing quickly with plentiful oxygen, I bet the strands/grains formed are much more loose due to the rate of creation, while the darker aluminum band is simply denser and more uniform. I think that if you were to look under a microscope or something, you would see the oxygen deprived parts would be more uniform, tightly packed, and straighter than the quickly formed parts. (You can already sort of see this when you break it apart)
Mr Brimstone that’s what I thought, although his idea seems convincing too. You may have to see it under a microscope or analyze the mercury content on the different sections
When doing a top and bottom tower, i strongly suspect the top tower collapses more quickly because of gravity! The structure is a little weaker it seems than the tower in your previous video, so it simply falls over because its side walls can't support the structure, while the bottom tower just gets to follow gravity down, which is a lot easier, doesn't cause it to fall sideways and thus doesn't compromise the integrity of its side walls so it can hold its shape longer!
Did you try it with different tempratures? Or combining different temperatures with different pressures? Playing with the first law of the thermodynamics...
Be nice if there was a way of saving the little teepee towers in acrylic or something similar so you could keep or sell/raise money for additional demonstrations. Love your work.
Why not try out a bunch of commonly available metals? Like copper, iron (this one doesn't actually do much with mercury apparently, which might be an interesting demonstration of the whole rock papers scissors nature of chemistry), titanium, lead, tin, and maybe even tungsten lightbulb filaments.
I was wondering from seeing the first mercury vs. aluminum video what would happen if you ran a small current through it enough to light a standard bulb maybe.
Fascinating. Have you tried heating the alumina whiskers to expel residual mercury? What is the aspect ratio of the whiskers? Have you made any SEM pictures and XRF scans of the whiskers before and after heating, with and without free O2?
the last video and this video was sick!!!! but I think experimenting with different metals will react a little bit differently, I am just curious on what the aluminum will do to bronze copper (molten metals) etc:-
Regarding upside down tower not falling as fast as the normal one: it's purely physical phenomenon. When growing upwards, any slightest deviation from the vertical course make the whole structure lean more and more to the side, but it ends up straightened up by gravity when going downwards. If you hold a pencil with two fingers and try to balance it pointing up/down, it will follow the same principle.
Awesome experiment! Gets me thinking on what would happen if the reaction happened in an oxygen-rich environment. Would it speed-up? Would the result be more clear? How about modifying the humidity to test Cody'sLab theory about the darkness of the oxide? In any case, thanks for the cool video.
Pretty cool, seeing the oxides form, the lack thereof with vacuum (or lack of most of it). Just read a book on inorganic chem and Mercury.. Apparently "galinstan" works similarly to Mercury though far less toxic. Galinstan being gallium indium and tin alloy, or perhaps eutetic
This can't possibly be the last video on the subject. There are so many things to try now. I personally would like to see multiple small pieces of aluminum/mercury, separated in a hexagonal grid, on a turntable, inside the vacuum chamber, with a thin oxygen atmosphere (or whatever other ingredient that makes the towers not grow when the air is missing). Then, I want to see some attempts to make the structures rigid, like some kind of hillbilly aerogel. Testing the electrical and thermal properties would also be something I'd like to watch someone else do. I wonder if that product called Cactus Juice would make the structures permanent without crushing them during pouring.
I believe the color diffractions are due to only reaction with the oxygen. Since the aluminum’s color in the vacuum is much more like its original/polished color, this can tell that the aluminum is much purer. There’s less oxygen so it just doesn’t oxidize. Since, and i have not looked into it (simply a guess), aluminum that is polished is just unoxidized aluminum covered in a protective polymer or oil, it can be safe to assume that the same is happening here just without the protective cover. So most likely after a while of sitting out even the dark bands of aluminum amalgam would oxidize from not being protected.

Is water vapor harder to remove than other components of air with a vacuum chamber? Any reason in particular you think that?

I think it is due to the formation of dialuminum dioxide from the low oxygen content.
