What the fuck? this isn’t a photo of space Seriously? Look Fluid Mechanics are really fucking important when entering and exiting the atmosphere
Learning Can Be a ‘Drag’
When Ajay Ramesh and Prithvi  Aiyaswamy, two seventh graders from Chaboya Middle School, San Jose,  Calif., visited the Fluid Mechanics Laboratory at NASA Ames Research  Center they found that the principles of fluid mechanics are not such a  ‘drag’ after all. The two youngsters both showed up for their experiment  with a half dozen toy cars they found at home. “Our project is to find  the best design shape that has the least amount of drag,” said  Aiyaswamy. “As we began the experiment, we realized that cars with a  sloping shape perform better.” The orange liquid behind the car  illustrates the wake, which can be used to determine drag for the car.  The green lines across illustrate the air moving across the car.  The boys were fortunate to request their visit when the Fluid Mechanics  Laboratory was uniquely set up to accommodate their request. Kurtis  Long, test engineer at the Fluid Mechanics Lab received permission for  the boys to visit and donated his lunch hour to help the boys perform  their test.  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. Image Credit: NASA/Eric James
