The soccer ball

My favourite piece of technology is the soccer ball. This piece had very important and decisive for many persons because this piece is used to play soccer. This sport is fun and it is a  means, in some cases, for people to stop being poor or have work.

It is made of a mixture untearable covered by PVC, is shaped like a sphere and contains air in their interior.

I play soccer all days so always used this piece. It is very important to play soccer. Because without it you can not play.

It is a special piece because even sheet of paper it can be a soccer ball.

Seems to be a simple piece, It is use it is much more difficult than it seems.
