STEM Learning Activity – CO2 Dragsters
CO2 dragsters are cars used by miniature racing cars which are propelled by a carbon dioxide cartridge, pierced to start the release of the gas, and which race on a 20 metre track. They are frequently used to demonstrate mechanical principles such as mass, force, acceleration, or aerodynamics. Two hooks (eyelets or screw eyes) linked to a fishing line on the bottom of the car prevent the vehicle from losing control during launch. In a race, senors records the time taken to reach the end of the track. Often, the dragster is carved out of balsa wood because of its light weight.
