Body Double, Lungs

For my project I am going to replicate a set of lungs. As I was thinking about what body part I was going to do, the lungs immediately came to mind. Without them, you die. This could be said about many other parts of the body as well, but the lungs seem so prominent to me since we can feel ourselves breathing, and even if we try to, we can't stop for more than a minute or two.

The materials I am going to use are:
-chain link (if I can find it?)
-tissue paper (preferably pink)
-saran wrap
-pipe cleaners
-tape
-wire
-paper clips
-some kind of small battery operated lights (anyone have suggestions on where to get these?)

I thought about doing something where my lungs would breathe, but I just saw Matt's post, so I'm going to leave that to him. Instead, my lungs are going light up and hang from the ceiling; a chandelier of sorts. I want it to be at least somewhat pink, because living lungs are a pinkish color, whereas unliving ones turn grey. I'm a little worried about using lights in the lungs, because I'm not sure where I'm going to get them, and I'm not sure if they'll be bright enough to shine through the other materials. But I hope so :)
