Kite Flying

A kite is an object which is made from a light material stretched over a frame. Due to its light material a kite will lift off the ground and fly when it is tilted into the wind.[General statement]

A kite is uses wind to make it fly because it is heavier than air. When wind travels over the while the second stream goes under the kite.[Explanation]

The upper stream creates an area of low pressure above the kite. The lower stream hits the kite at a shallow angle and creates an area of high pressure.[Explanation]

The high pressure area has a pushing effect while the low pressure area has a pulling effect. The combination of push and pull can creates enough force to lift the kite into the air.[Explanation]

Kites have been known for thousand of years. They are used for military or scientific purposes. Todays kites are much used for leisure and competition.[Closing]
