# Can't fly it 'till you build It!

## Think you got what it takes to fly a kite? Let's find out.

Before you fly your kite you have to know some basic math and common sense, so do not think you can just have a big hole in your kite and expect it fly.

## I know what you are thinking." Math. What math?"

The only word to describe the math in this is the measurements. The measurements is what tells you how big your kite should be, how much strig to use, and how much paper, covering of the front of the kite should be. The obvious thing you need to succeed this is a basic tool of measurement.(ruler, yard stick, etc.).

## Let's start off building the most classic of the classics of kites... Diamond Kite!

Now what is better present a kite than from the beginning... No, the beginning, beginning. Get your history book. You are about to learn the of the history of the kites.

## The History of Kites Between 1000 BC and 0 BC

Somewhere between 770 BC and 221 BC large wooden kites called muyuan were invented for military purposes. This period actually contained 2 separate periods of Chinese history, the Spring and Autumn Period (770 BC - 476 BC) and the following Warring States Period (475-221 BC). Kites were seen as technology, and it seems the first ones were invented in the province of Shandong. There is a record of a certain master of joinery named Mu Zi who developed a man-lifting kite over a period of 3 years. It was called the Wooden-Black-Eard-Kite. At least one more kite of this design was made in later years, by other craftsmen. There is a record of further development of these kites during the Chu-Han War of 203-202 BC. Besides spying on enemy positions, kites were sometimes used to deliver urgent messages.

## The Famous Steps to the Creation of the Diamond Kite

The fisrt step is to use your paper and cut out a diamond shape.

## The Main Word is Perpindiclar

Now to put the first stick from the bottom of the kite to the top, but be sure the stick does not out grow the kite. Then put the second stick from the right end to the left. Continue to tape the sticks to the paper. if you have it right, the sticks should be perpindicular. Don't know waht perpindicular means. You should find a good example on this picture.

## Almost to the End

You then connect a string to to where the two sticks meet and make sure the string is very long.

## The Decoration

Finaly you decorate your kite as you wish and add a long tail made of paper taped to the diamond, and voila. You have your own kite!

## The Kite Math Problems

Problem 1: In 1820 George Pocock connected several large kites to a carriage and pulled it from Southhampton to London. Since road taxes were based on the number of horses used to pull a carriage, he was able to avoid any taxes! The 60 mile trip took two hours. Modern kite buggies now go twice as fast but seldom go as far. How fast was the carriage moving? By my calculations, the carriage was moving 120 miles per hour.Problem 2: In the year 169 BC, the Chinese General Han Hsin used a kite to measure the distance between his camp and the wall of the enemy city. His soldiers then dug a tunnel the same distance in order to crawl under the wall and attack from inside. The city was conqured by a kite! How can you measure a minimum distance with a kite? By, measuring the string and how long it goes.
