A paper plane is a simple flying toy made by folding a sheet of paper into the shape of an airplane. It mimics the design of a real aircraft, with wings, a fuselage, and sometimes even a tail. When thrown with the right technique, it can glide through the air, showcasing the principles of aerodynamics. The art of creating and launching paper planes has been enjoyed by people of all ages for generations, providing a fun and creative way to explore the wonders of flight.
