A paper airplane is a simple model aircraft made from a sheet of paper. It is created by folding the paper into a specific shape, which allows it to glide through the air when thrown. The design and weight of the paper can affect how far and how well the airplane flies. There are many different designs for paper airplanes, ranging from basic to complex. Some popular designs include the Dart, Glider, and Stunt Plane. People of all ages enjoy making and flying paper airplanes, often using them for fun competitions or educational purposes in science classes to learn about aerodynamics.
