The boys placed the cars in a pool of water. Dye was added to the water and photos were taken of the dye flowing around the toy cars. "Air and water have the same flow characteristics, but by using water we can slow down time and see the flow more clearly," explained Long. With these photos, the boys could measure the drag of each car. The orange liquid behind the car illustrates the wake, which can be used to determine the car's drag. The green lines across illustrate air moving across the car.
