| Sketches of the first prototype |
In this unique challenge, students try to harness the wind from a fan to power their cars down a runway. The goal is 15 feet, or 180 inches. Students can use straws, paper and tape for their construction. Students collect data on their trial runs and make improvements for the next trial. Aerodynamics, symmetry along with a sturdy design are the key elements to this challenge.
