  2. My presentation • I’m done with my kite power point and now we are about to fly our kites. I hope that my kite works good .

  3. Things I want to know about kites • I want to know different types of kites? • I want to know how different types of kites work? • And I want to know all about diamond kites also? • My favorite kite is a diamond kite because it is nice and simple.

  4. PICTURES OF KITES

  5. TETRAHEDRON KITES • A tetrahedral kite is a multicelled rigid box kite composed of tetrahedrally shaped cells. The cells are usually arranged in such a way that the entire kite is also a regular tetrahedron. The kite can be described as a compound dihedral kite as well. • A Tetrahedral kite being flownThis kite was invented by Alexander Graham Bell. It came about from his experiments with Hargrave's Box Kites and his attempts to build a kite that was scalable and big enough to carry both a man and a motor. As such, it was an early experiment on the road to manned flight. He worked on the kites between 1895 and 1910.[1] Bell wrote about his discovery of this concept in the June 1903 issue of National Geographic magazine; the article was titled "Tetrahedral Principle in Kite Structure".[2] • From an initial one cell model, Bell advanced to a 3,393 cell "Cygnet" model in 1907. This 40-foot (12.2 m) long, 200 pound (91 kilogram) kite was towed by a steamer offshore near Baddeck, Nova Scotia on 6 December 1907 and carried a man 168 feet (51.2 metres) above the water. • Bell also experimented with a large circular "tetrahedral truss" design during the same period.[3] • The tetrahedral kite, while not easy to make compared to the simple cross kite, is very stable and easy to fly. It flies well in moderate to heavy winds if it is properly set up. • I got this off of a web site and the web site was Google web

  6. HOW MY KITE FLEW • My kite flew great and it was nice . I think my kite flew the best that was what every body was saying . Well all of the kites were good too. • The materials • Straws • Paper
