A lot of these questions are very science-y and I don't know how to answer them because I didn't consider the scientific logistics when making this semblance and I don't have a great understanding of physics. I really just tried to make something I thought was cool, unique, and well-balanced for the RWBY world, so a lot of my answers don't have anything other than "I thought it was cool" or "I thought that would be too powerful/unfair" as the response. I'm sorry if this is too, ah, vague or inconsistent with actual physics? :(

1. Soundwaves and heat travel into the pocket, but they don't stay in there forever until the pocket opens. They eventually disperse (don't know if that's the correct word.) Like, if I yell into a pot, close it, and then open it, I won't hear my yell come back at me from inside the pot.

2. Thick enough to be visible. Plus, it emits a glow since openings are made of Aura.

3. Pockets don't have any specific physical shape -- it's just like an empty expanse of nothing. When something is placed in it, it just kinda floats in there. If the opening is too small, the user can make it bigger.

4. Do you mean like, they put a board inside a pocket, opened the pocket horizontally, and tried to use it as a platform? I don't think that would work. Although, I suppose if they wanted a platform, they could just open the pocket opening face-down and stand on the backside. I hadn't considered using pockets as platforms.

5. Bottom of bottle, mirror, or camera -- sure. However, keep in mind that the user still has to "aim" portal placement. It's like looking into a mirror and then trying to shoot something you see in the mirror with a gun. You're probably going to miss.

6. The pockets themselves can change in size however much the user likes as long as they have the Aura for it. Same goes with openings, although openings don't cost Aura. If something is in a pocket and the user makes it smaller than the volume of that object, the pocket is destroyed.

7. Oh. I suppose that would be possible, yeah.

8. Oh yes, that'd be possible. The gravity pocket would have to be pretty big to pull a human, though. I honestly hadn't thought of that or the above application either.

9. I don't really understand this question.

10. If someone who is inside a pocket has the ability to make portals or teleport (e.g. Raven), they can.

11. If a pocket was filled with gas, and then destroyed, the gas would appear around the user. However, I don't think that would be enough to create a vacuum. Then again, I don't know much about air pressure or gas.

12. Again, I don't know. That was just a rule of cool, I suppose. I guess I should note that an item that is already frozen beforehand will melt inside a pocket, but an item that is placed into a pocket powered with Ice dust (and thus frozen) will not.

13. I don't know if it would be positive or negative (how about neutral? is that a thing? that's what google says wall sockets are ¯\_(ツ)_/¯), but I guess it would be charged via conduction, since it gets charged by passing through a thin fim of Dust over the pocket opening? Again, I really just imagined lightning-sparks-that-shock-things. Like, you put a cell phone with low battery inside, pull it out, and boom! Battery full! Or you put a spear inside, then pull it out, and boom! Spearhead is covered in electricity! Etc.

14. If you tried to take a picture from inside a pocket, you'd just get a picture of whatever was inside the pocket -- probably nothing.

15. They can only do so manually (take item out of one and physically place it in another).
