A Chuck Glider model is a simple, hand-launched, lightweight glider, typically made from foam, balsa wood, or plastic. It is designed to fly short distances through the air using basic aerodynamic principles. The glider is usually small, easy to assemble, and doesn't require any motors or batteries to operate. You simply throw it by hand, and it glides on air currents. Chuck Gliders are popular as toy models or for educational purposes, teaching basic concepts of flight such as lift, thrust, and stability. They are often used by kids, hobbyists, or as a fun activity in aerodynamics demonstrations.
