A paper airplane is a simple toy made by folding a piece of paper into a specific shape that can glide through the air. The design typically involves creating wings and a body, allowing it to fly when thrown. Paper airplanes can vary in size and style, with some designs optimized for distance and others for acrobatics. Making paper airplanes is a popular activity for children and adults alike, often used in educational settings to teach principles of aerodynamics and physics. Various competitions exist, where participants aim to create the longest-flying or most acrobatic paper airplane.
