It is now thought that the first kites flown over 3000 years ago, were made from leaves.
In the 18th and 19th centuries, kites were used as vehicles and tools for scientific research.
There are kite festivals all around the world. At many of them, participants come to watch, fly, and compete in contests and other kite-related activities. In a common kite contest, kites are judged based on their size (the biggest or smallest kite), which kite can fly at the highest angle, and kite-racing, among many other competitions. In the U.S., you can probably find kite festivals hosted in your city. One of the most popular kite fests in the country is the Washington State International Kite Festival. It is held in mid-August every year in Long Beach, Washington for a week.
