Kites have been around for thousands of years. In that time, people have found many uses for
kites. The first kites were probably flown in China. Kites flying at night over the houses were
supposed to keep evil spirits away.
Americans used kites to try out new ideas in science. Benjamin Franklin hung a metal key
from a kite string. He showed that lightning was electricity. The Wright brothers used kites to lift
themselves into the air. Later they made one of the first airplanes.
Kites are easiest to fly in open spaces. The wind should be blowing between 5 and 15 miles an
hour. With less wind, it’s hard to lift a kite. With too much wind, a kite is hard to handle.
