In Asia, there are special competitions where kites have complex designs and are fitted with instruments that make musical sounds as the wind blows through them. Although all kites have a similar structure （结构）, they are widely different in size and shape. Kite-fighting competitions are also held, in which competitions us their kites to attack and bring down their opponents’（对手）kites or cut their strings（线）.

For more than 15 years, the Big Wind Kite Factory has been giving kite-making and kite flying classes for the children on an island in Hawaii. In its kite-making lessons, students can make kites in as little as 20 minutes! Children as young as four years old can learn how to fly a kite. Jonathan Socher and his wife Daphne started the kite factory in 1980. Their kites are made of nylon（尼龙）.Their designs are Hawaiian themes created by Daphne. The designs are cut out of the nylon with a hot knife that seals the edges and then fastened directly onto the kite. 

The kite that is used to give lessons is regular diamond kite with a rainbow pattern. The difference between this kite and the ones they make during the lessons is that it is a two-string controllable kite. Big Wind employees fly the kite and for a few minutes show students how pulling on one line and then on the other controls the direction the kite goes in. Then the controls are given to the students.

Jonathan insists that it is not necessary to make a huge impressive kite to have fun making and flying kites. Even the simplest structure can work, and can give hours of fun. Go on, give it a try!
