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 unique shape. These kites were invented in the late 19th century and are often used for recreational flying and scientific purposes, such as weather monitoring. Box kites can be flown in various wind conditions and are popular among kite enthusiasts and hobbyists.
