Making And Flying Kites

Kites are devices that are meant to be flown in the air 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. In fact, nearly all kite flying festivals all across Asia have "kite fights," which is a venerated and ancient custom where participants try to down their opponents' kites by cutting their lines. This is accomplished by using small, highly maneuverable "fighter kites" that are connected to glass-coated "cutting lines." These specialty "cutting lines" are used to cut off the lines of contending kites.


In Korea, men, women and children fly kites all throughout the opening days of the New Year. Kite flying is also something to look forward to, and an important component of the boys’ festival, which is held each May in Japan, and in China, one day each year is commemorated as Kites’ Day. On those days, thousands of kites fashioned like fish, butterflies and dragons take to the air and soar over the cities and towns. Thailand also sponsors an International Kite Festival in which all kites fall into one of two classes: chula (male) or pakpao (female) kites. The kites are immense and require several people to fly them. There are also kite-flying competitions held yearly in the United States and Canada.


Types of Kites

There are many different types of kites. The simplest kind of kites is the two-stick solitary plane bow kite. It can be purchased ready-made or it can be put together from do-it-yourself kits or made exclusively by hand. When creating plain kites, the sticks that are utilized can be of any sturdy, light wood with a straight grain. The covering material can be ordinary brown wrapping paper, or a wispy, light cloth, such as silk or nylon. Plastic sheets of different kinds are also used. In addition, cloth is used for the tail and a string for the flight line. There are more advanced types of kites that can be made.

The box kite consists basically of two rectangular boxes, open on two parallel sides each and connected by a common framework. Lawrence Hargrave conceived of the original design in the 1890’s. Box kites are more difficult to build than stick kites, but they are excellent flyers and will maintain their position for long periods. Box kites also adjust well to variations in the breeze, and they do not require a tail.

How to Fly Kites

Kites take to the air, like airplanes, on the aerodynamic theory of wind pressure against a heavier-than-air item. The motor and propeller of the airplane create a wind pressure as they move the plane through the air. When the pressure is strong enough to conquer gravity, the plane is pressed up and permitted to stay in the air. The same effect of wind pressure is produced by the kite flyer as he sprints across an open field. As the kite moves in opposition to the wind, the string tips the face of the kite onward. The wind shoves up on this tipped face and raises the kite, just as a wedge pressed beneath an object lifts it up.
