Can you make a stable paper airplane?
Try out a number of designs from the computer. You will get step-by-step folding instructions to create different plane models from simple to complex. Test your plane to see how stable it would be in the air and learn the importance of a wind tunnel in the engineering of airplanes. Make adjustments to your computer designed plane or start again and create your own design. Experiment to see what happens if you add weight or change the shape of the wings.
