A box kite is a type of kite that has a three-dimensional structure, resembling a box. It is made up of a frame covered with lightweight fabric or plastic. The design allows it to catch the wind effectively, providing stability and lift. Box kites can fly at higher altitudes than traditional flat kites due to their shape. These kites were first developed in the late 19th century by inventors like Lawrence Hargrave. Box kites are often used for recreational flying, scientific experiments, and even as a platform for cameras in aerial photography. Their unique design makes them popular among kite enthusiasts.
