How Do You Build A CO2 Dragster?
CO2 dragsters are used to teach about motion, aerodynamics and thrust. They are also raced competitively in many schools and in national league competitions. When it is punctured, a small canister of pressurized CO2 sends the car shooing forward at a tremendous rate of speed. To win, a car has to be light, streamlined and well-assembled. Buy a CO2 dragster kit such as the one in Resources below. CO2 kits come with balsa or basswood body blanks, wheels, axles and all the other parts you need to make your own CO2 dragster.
