KITE FLYING
Launching a kite is easy in a good wind. Fighter kites, the flat dragons and the non-rigged kites are the easiest to get up in the air. When launching a kite try and get it up on the first pull. Walk the kite down and either have it stand itself or have someone stand behind the kite and hold it. Wait for a breeze and shout to your assistant to let go. Pull the string in hand-over-hand in quick yanks, walking backward as you do it. Drop the string on the ground so as not to tangle it. Your kite will tell you when it is ready for more string. Slight pressure means more string. If it drops, a yank will get it climbing. A model plane made from light weight construction can also be used.
A toy balloon can help demonstrate how the force of air molecules can move a jet plane. Blow up a balloon until it is full of air. Hold the end tightly and then suddenly let go. As air shoots out from the nozzle, the balloon spurts away. The force of the air molecules, pressing against the balloon walls is very powerful and there is enough force in this air pressure to send the balloon flying.
Cut two strips of paper approximately twelve inches in length. Turn on an electric fan, place one strip in front of the fan and observe what happens. Later place the other strip in back of the fan and see what happens.
