Ed,

That's very exciting that you are planning on putting this into your curriculum!

I use Midwest Technology Products to order all of my CO2 car accessories. Here is a link: http://www.midwesttechnology.com/cat...-%26-Supplies/

I recommend buying in bulk if you can. You should start will axles, wheels, screw eyes, washers, and CO2 cartridges.

As for the launcher, that is going to depend on your budget. This is the one I have: http://www.midwesttechnology.com/pro...0--731054.html

It is simple to assemble and easy to use. If you want to get a little fancy, I recommend PITSCO. Here is a link: http://www.pitsco.com/Technology/Dra...G3_Race_System


One final tip. If you order from Midwest Technology, always request a quote instead of going with their prices online. Their quotes are always 10%-15% cheaper. I always deal with Sarah Cruz. Here is here email: scruz@midwesttechnology.com

Hope this helps!
