Cadmium + Aluminum Armor = Awesome!

[Zallek Windblade he/him]

So I'm much to lazy to find it, but I remember something here talking about Aluminum negating the power of time bubbles. Because of this, I came up with an awesome possible villian idea. 

A villain originally thought to be an extremely powerful steelrunner, this is a monster, leaving a room full of corpses before anyone knew what happened.

Eventually, it is revealed that this is Slider(Cadmium misting) who has amassed enough aluminum to make full armor and knives.  With this he can put up a cadmium bubble; freezing the whole area, but not freezing him because of his allomancy negating armor. 

Because of this, he can go full speed while everyone else is frozen in place,  running around with a runny-runny stabby-stabby rampage.

So, assuming my imagination is not completely stupid. Cadmium could actually be cool!

This is interesting. I am no time bubble expert, that's Kurkistan's domain. But my guess for why this would be a problem is that the armor will block the time bubble itself, not just it's affect on the misting. If you had a team mate in the armor, inside the bubble, I feel that may work? But I'm guessing that if you're burning cadmium inside your own stomach, and your stomach is surrounded by aluminum, that the time bubble won't get past the aluminum and won't work at all. I'll be very curious to see any responses on this though as it's not my realmatic strength.

I also suppose this is largely based on how aluminum negates it, is it like a wall, creating a "shadow"? Or does it create its own little bubble?

This WoB indicates it would form a bubble around the aluminum object.

QUESTION

(Heavily paraphrased for clarity) Can you drop a speed bubble whose border goes through a piece of aluminum?

BRANDON SANDERSON

I think you can’t do that, it would cause the bubble to collapse. Verbatim: It’s probably going to act like you are trying to set up speed bubble on something that’s too small and moving

FOOTNOTE

Note: Alternatively (obviously I can’t see any gestures going on), this could be interpreted as: Q*: If you dropped a speed bubble whose border goes through an aluminum tube, is the inside of the tube affected by the time distortion? A*: No, the bubble would go around the tube. This was a Sharder questions, so a clarification would be very nice. Note response: This is essentially correct, and Brandon understood what I meant. -- FS

 My concern is that if aluminum is already surrounding you, there's no gap for the bubble to push through. Perhaps even a small gap would be enough. Or maybe it forms around the misting anyway. But I feel like touching and being surrounded by aluminum would just prevent you from using investiture and forming the bubble at all.

Maybe pairing this with a primer cube could work? I'm not good with time bubbles either, but if you charge the primer before putting on the armor...

Not to be a debbie-downer...but even if you solved the problem of actually getting the bubble up and keeping it up, you'd have the problem of extreme air resistance.

Just off the cuff, if you were in a cadmium bubble slowing time down by a factor of 100 (we see Wayne throw up a bendalloy bubble and be able to track bullets through the air, so this is totally reasonable), then you would essentially be moving 100x faster than the rest of your reference frame (inside the bubble).  Meaning, at a gentle walking pace of 5mph, you would encounter air resistance as if you were piloting a jet...

Near as I can tell, it would be more like wading through jelly than running around.  You could move around though, and compared to people inside the bubble you would still be moving very quickly, it would just be exhausting and frustrating.  That said, cadmium burns super slowly, so it could be viable if you could get the bubble to stay up.

I have crazy mental images now off someone wrapped up in aluminum foil and robbing banks.

My issue with that postscript WoB is that apparently it was derived from hand gestures, not actual text, and I don't see how you can reach that conclusion from what was actually said.

I agree. The wording makes it sound like the aluminum would interfere with the bubble enough to cause it to collapse before its effects were manifested. 

[Kingsdaughter613 she/her]

Except we know that you can have an alluminum gun + bullets in the bubble...

[+Extesian he/him]

Yeah that's fair Spool, Calderis. I was taking note of the "note response" part as it sounded like the recording was challenging but the actual words are probably more reliable either way my main point was that the bubble wouldn't work, and that interpretation strengthens that.

Aluminum through the borders of the bubble, not just generally inside it. In any case, my issue is with the idea that it would create empty zones where time isn't affected, which I don't think should be the case.
