Where do I find a simple diagram to build a science project to prove
Newtons Third Law using Air Pressure to propel an object

Hello!

Thanks to your government dollars at work, NASA has built a lesson
plan for teachers to help them explain Newton's Third Law by building
and testing a "Rocket Car" built from a balloon.

http://vesuvius.jsc.nasa.gov/er/seh/Rocket_Car.pdf

This is a PDF file (you can download a free reader from
http://www.adobe.com/products/acrobat/readstep.html ) that contains
assembly diagrams as well as other information.  It would be a great
starting point for a science project.

I also found cool program (PC or Macintosh) that will let you
"virtually" build and race a balloon car.  Very fun!

Good luck with your science project!

I asked for a diagram on Newtons Third Law using air pressure not Law of Motion.

I need to specify my request.  I wanted an example to build using a
plastic pop bottle to demonstrate Newtons 3rd law of Motion using Air
Pressure.  Im sorry if I wasnt specific

Your request "Newtons Third Law using air pressure not Law of Motion"
is unclear to me.  Newton's Third Law *is* a law of motion (using
action/reaction) and has nothing to do with air pressure.

I did find, however, a page with a project similar to the ballon car,
but uses a 2-liter pop bottle pressurized with a bicycle pump:

Is that more what you are looking for?
