Oh my sweet Lord I haven't checked the thread since I last posted yesterday, but it seems you people just won't read what is against your beliefs. I for one am 18 years old and I like watching cartoons because I see no way they are different from movies and personally movies are just way too lame(most of them at least) and I just like watching cartoons, grew up on them I guess. After reading the posts from today I'm pretty sure that at least a couple of people that post here are kids it's one thing to come with solid arguments/theories like actual physics or maybe even wacky theories like mine with the Tai-Chi. But most of the definitive statements you guys have made are just freakin me out. After I think??a few people have already said that fire is plasma as well as lightning .. you still don't understand the concept. Now carefully read what JonathanWolf wrote or some others(VincentMagius,tc2r or even KilalaRose) and pick a side if you really want to pick sides. If you read what these 4 ppl wrote you'll have a pretty clear idea on everything. Now if I see another person posting some silly thing like subdivisions to bending and other stuff I will definetly freak (not that i haven't already) [Vine-Bending "I waterbend the WATER in the Vines", Ice is frozen water, lightning is a hotter much more agitated for of plasma and fire is plasma too, sand is little particles of earth]
Oh and @JonathonWolf the original question was "How does Azula bend blue fire?" and the answer to that is that blue FIRE is FIRE in itself .. just a different type/different characteristics. And I did agree somewhere in my posts with the "sustained heat" thing She doesn't shoot plasma like the sun has, it's just hotter than usual fire, but it still takes a while to melt a metal. Before a metal turns red and stars actually melting it has to be heated intensely. For everybody else that did not get that idea just look at a clip with a smith smelting shields/swords or stuff. Notice how the metal is left in hot charcoal for a long while before it turns red and it can be worked(hit with a hammer repeatedly) and brought to a more refined shape. Now think how "melted" is that metal if it requires so many blows from a big hammer to make a few little dents in it.
I'm through responding to posts by anyone else but JonathonWolf,VincentMagius,tc2r,KilalaRose and whoever else has something intelligent to say there were others but I can't write you all now can I ?
