2. Kites need wind to fly and because there are many kinds of winds there are
many kinds of kites to suit them. Most kites fly in gentle winds with speeds
between 8 and 12 miles per hour. Kites are heavier than air and must be
able to overcome gravity. They use the air flowing across their surfaces to
give them an upward force. There are three main forces at work on a kite.
These are gravity, lift, drag.

3. The first to make a hot air balloon were the Montgolfier brothers. The first
hydrogen balloon, the Charleire, was inflated in August 1783. The very first
passengers were a duck, rooster and a sheep. The first human passengers went up
in September 1783. There is a gas burner that heats the air to 100 degrees Celsius.
The hot air is lighter and less dense than the cool air around the balloon. The
heated air causes the balloon to rise. When the air inside the balloon cools, or
when the hot air is let out, the balloon goes down.
