2. Why Kite can fly
Kite flies up into the sky by the force of wind. When we look at the flying kite, it always flies against the wind. Also, the body of the kite is always in a tilted downward direction, which is the key point for kite’s flying. The kite is very light, so the pushing of air is enough to let the kite fly in the sky.
As we know, the kite has its own weight. Then why it cannot fall down from the sky? It is because that the air gives the much support for the kite, it makes the kite be able to float or fly in the air.
It is really very interesting. Attached to a long string, the kite can be sent up through the action of wind on its surfaces. Its distance or height is controlled from the ground by playing out the string.

4. The skills of flying kite
For flying a kite, you’d better choose a windy day. In north China, spring is the best season for flying kite in a year.
Before flying a kite, you should make clear the wind direction according to the flags nearby. Then the kite should be flown against the wind. If the wind is big enough, just by loosening the string, the kite can be flown up. If the wind is small, you should run for some distance to fly it.
After the kite is flown in the sky, if you feel the kite has a downward trend, you should quickly roll in the string. If you feel that the kite has a pulling force, you should roll out the string in time. After the kite is flown about 800 meters in the sky, you can tie the kite on the tree or other object, allowing it to fly freely.
