Kites are ingenious contraptions that are intended to be flown high in the sky at the end of a string. Making kites and flying kites is an enjoyable and relaxing activity, as well as a competitive game in several parts of the globe. As a matter of fact, nearly all kite flying festivals all across Asia have "kite fights," which is a venerated and ancient custom where players attempt to cut down their adversaries' kites by cutting off their lines. This is achieved by using small, extremely maneuverable "fighter kites" that are connected to glass-coated "cutting lines." These specialized "cutting lines" are used to cut off the lines of contending kites.
