The velcro
History
The velcro is one of the inventions that most all the peple used it. The inventor of the velcro was George de Mestral. the idea came to him in 1941 after returning from a hunting trip with his dog in the Alps. He took a close look at the burrs(seeds) that kept sticking to his clothes and his dog's fur. He examinated them under a microscope, and noted their hundreds of'''hooks'' that caught on anything with a loop, such as clothing, animal fur, or hair. He saw the possibility of binding two materials reversibly in a simple fashion, if he could figure out how to duplicate the hooks and loops.
Materials
Velcro is made up of two separate sides.One side is made up of hooks, and the other side is made up of soft loops. Both sides of a strip of velcro are made of nylon, but the process for making the hooks is different from making the loops. The hooks are created under an infrared lamp. The loops are made of matted, nylon fibers that provide the mates to the hooks.
Uses of velcro
Clothing such as jackets, bags and shoes. It can be used for doll and pet clothing. The velcro is useful for hanging items such as greeting cards, children's artwork, christmas lights, garland and other decorations. Velcro comes in many shapes and sizes. It is available in small coin shapes, strips and rolls. it comes in both sticky backed form and sew on form. The velcro is wider and water and temperature resistant.

Halls of Fame in 1999 for his invention.
Introduction of the project
The reason of what we are doing this project is because we want to know more about the famous inventors of our time, this project teach us something new about famous projects that make the world change. This project also is interesting because we are searching some awesome projects that are already done but we don't know who created it and we are constant using in our daily life. This project will be graded by computer and english department.
The inventor that i am going to research is called Georges De Mestral.
