Carbon...
no they should be made out of uranium.
Figure it out !!
Aerodynamics of the car, the size of the wheels, the weight of the car, and the size of the CO2 cartridge.
first you buy a mouse trap, then you find old toy car wheels. next you fashon the wheels so they spin, then you take off the metal ontop of the trap, and place there a co2 can. then you tape it down and slightly open the cap. LET IT GO My brother just made a CO2 car in his woodshop class, then he just attached it to his car, and he got alot of distance.
rubber
To make a car that has wheels made out of compact discs, everything else must be in porportion.
the wheel is made of rubber
Casting Casting
In China
Standard car and truck wheels are made of steel, "alloy" wheels are made of a lightweight aluminum alloy.
A CO2 car decelerates due to factors such as friction with the track surface, air resistance, and rolling resistance from the wheels. These forces act in the opposite direction to the car's motion, causing it to slow down.
