Here is my post, without asking about my element. Emma, please tell me if I can tell you about my self/dreams! If you say yes, I'll post it in another reply. For now, though:
What is Jin's element (if you're allowed to say)?
Can firebenders burn themselves, or are they immune to - or, at least, not as harmed by - fire once they start training?
In the movie "Sorceror's Apprentice", Balthazar says something like, "Sorcery is a mix of magic and science." Is this true for chi? For example, when heat is created, the atoms are moving, constantly in motion, and faster than before. The faster they move, the hotter they become. Using this, could airbenders create fire by manipulating the atoms in the air?
Is airbending like telekinesis? Like, you could created a "bubble" of air around something, and then lift it around in the bubble?
Using that last technique, could airbenders control the other elements?
I'm sure I can think of more, but not right now. Anyway, I think this is enough for you, Emma. Thanks!
