My final mousetrap car is the fifth in a string of designs that tested how well I could make a car from cheap and light materials. [Read the side description for a brief on how mousetrap cars work].
Using chipboard, fishing wire, and leftover welding rods from my Metal’s I class, I built car skeletons that were easily customizable and replaceable. The balsa wheels are one instance where I did trade lightness for price, and they are the only expensive part of my project. By not gluing them to any surface, however, I saved money and eased the process of iteration.
