box kite
Three-dimensional wind toy
A box kite is a kite with a three-dimensional frame, typically rectangular with open ends, covered in fabric or paper on its sides.
The boxy structure provides stability in strong winds without requiring a tail.
Box kites were used in early meteorological research and aviation experiments: Alexander Graham Bell experimented with box kites before building aircraft.
