Mechanics from the Junk Drawer
Chopsticks, rulers, and paper fasteners become quick linkages. A ruler lever can lift a small cup, while a brad-fastened joint turns linear pushes into arcs. Explore how changing pivot points multiplies force or motion. Share a short clip of your clever linkage and we will feature standout designs in our next roundup.

Bottle caps and barbecue skewers make lightweight wheels and axles. CDs spin smoothly as flywheels, while rubber bands add grippy tires. A cardboard chassis shows how friction shapes steering. Try three surface types and compare performance. Comment with your results and subscribe for weekly experiments that sharpen mechanical intuition.
