So how does science and technology play into wind tunnels? If you've ever stuck your hand out of the window in a moving car, you understand a concept called drag. If you tilt your fingers down, the air moving past your hand will push it down. Drag in racing is bad. This causes drivers to slow down. So wind tunnels help teams eliminate the friction between the car and the force of air molecules moving through the air.
