Drag parts onto your car to build a wind-powered sail car. Every part you add changes the
drag, rolling friction, and center of gravity — which decide how fast
and how stable your car will be. Aim for lots of thrust, low drag, low friction, and a balanced center of gravity, then
press Test in Wind Tunnel to see your speed score!
