5 . Tie the corners to the points of the frame, and then attach a tail of cloth

6 your kite. Finish with a good strong kite string, one

7 will be long enough to fly the kite high. To get the kite ready for the experiment, there are three very important

8 . First take a long sharp piece of metal and attach it to the longer leg of the cross,

9 a foot or more beyond the frame.

10 , take a metal key and tie it to the end of the kite string, the end that will be on the ground near you. Finally take a silk

11 and tie it onto the kite string, just above the key. This silk ribbon needs

He earned a degree in Natural Science with first class honours in just three years. Hawking then headed to Cambridge to study Cosmology. He completed his PhD and t........
