NachoMahma is spot on, that's the best one I know of, but anybody who has not seen this before might find such a brief run down slightly confusing without an images to back it up.http://www.scribd.com/doc/3394749/lung-model-with-two-lungs-and-diaphragm-labHere you go. Feel free to substitute the 3 way hose connector with 2 straws, one for each balloon, and a liberal amount of duct tape.

. I like that. It would be much better in a classroom environment.
. I understood what I wrote perfectly.
:) I understood it as well, but only because I had done it before. I figured a picture or two might help. I merely meant to supplement, rather than undermine. ;)
Hiya phalanx447,Thank you so much for helping me with my enquiry - as I mentioned to NachoMahma, once I had the illustrations from your link to highlight his instructions, I was able to understand what they were trying to tell me.Have an awesome day!
. You figured right. The pictures truly were worth 1K words.. The "<snicker>" was supposed to acknowledge that just because I understood it, doesn't mean that anyone else did. I'm glad you posted better instructions.
. Cut the bottom out of a two or three liter soda bottle. Stuff two balloons (lungs) inside the bottle so the mouths poke through the top and are open to ambient air. Cover the bottom with a cut balloon (diaphragm) so that you can move it up and down to deflate/inflate the "lungs."
Hiya NachoMahma,Thank you so much for answering my question - once I checked out Phalanx's link to see the illustrations for your instructions, understanding dawned on me lol :) Have an awesome day!
Did you steal that from Bill Nye?
Nye stole it from his hero...I forget his name "the wizard"
Dont believe me, check out billnye.com and check his memoirs.
Mr. Don Herbert. Wow, what a great show that was.
. I wouldn't be at all surprised if I didn't first see this on Mr. Herbert's show, Watch Mr. Wizard (those old B&W clips make me feel old heehee), but, as frollard points out, it's been around since long before Mr. Wizard.. Definitely not my original idea. ;)
phalanx wins the internet :D Good job
Oh, okay, I just remembered that from Bill Nye's show.
It's been a standard classroom experiment for a long time - great for visualizing pressure etc.
to clarify, bill nye is my hero.
