Science Buddies: "Ask an Expert"

my requirements for this project is that i have to use a 1kg mass that is supposed to be attached to the mobile. The goal is getting to go 10 meters. I need help on the construction of the mobile. I am clueless as to the materials needed to build the mobile. I am planning on using wood as the body and CD as the wheels. Any suggestions on the other materials needed or how to put this together?
