I was thinking that maybe plasma has a lower density than air but it's impractical according to Wikipedia. The problem with using hydrogen is that it would take up a lot of space inside of someone possibly?

Personally, I'm tired of defending gmo's but that seems to be what I'm constantly having to do. I kind of see the gmo-free craze as something like the "natural" craze, where most of the people who obsess about it don't know what it even means. Normally, I just let most people just poison themselves with ignorance, assuming they figure it out eventually in an effort not to sound too nerdy. However, I guess the cat is out of the bag now and I've been ranting and raving to everyone who will listen (everyone, because everyone I've raved around is ignorant about it). Does anyone have similar problems? I'm relatively for all the health labels, even if I don't always believe them, and I don't work for monsomato or any of those companies and I don't plan to(I'm in biology for the brains), but when people say that "gmo's are bad for you" and have no reason why other than "science" I want to bludgeon them.

I'm not a physicists, and I never will be, so I'm not sure if my theory goes in this part of the forum, and if it doesn't just move it to wherever in the physics forum it's appropriate. One of my hobbies is writing, so in my AU which is not quite a fantasy story there are people that evolved from birds. I didn't want to have the same mass as birds or have four chamber hearts so I decided that the best attribute for them to have is a plasma bladder, which is kind of like a swim bladder in fish which can contain air, but it can instead contain plasma which the creature would absorb from the environment and produce inside of them. I want to know if this back story is physically possible considering the properties of plasma. My second question if there are any glaring drawbacks or limitation. Third question is if everything from before is fixed how would a flying city be possible. Thank you very much for your time.
