CO₂  racing is an event at our state skills competition.  Members design and build the car that they believe will win.   Everyone has different styles of cars.  However we are only allowed one car at the state competition.  To eliminate the rest of the cars we have a race.  The racing is bracket formatted and the grand champion gets to race their car at the state competition.  Each car is powered by a carbon dioxide(CO₂) cartridge.   When a button is pushed a lever drops puncturing the cartridges in the two cars creating airflow and pushing the cars forward at a speed of at least 100 mph.

Here are some of cars that raced:
