the reading about Yo-yos was very interesting for me because i didn`t know the origin about this  toy, after i read the lesson i felt motivated to navigate in the internet to search  more information about it.
The information says this popular toy was invented in the V century B.C. in Grace.
the yo-yo is compound by two discs connected by an axel with a  tied string. It says that we can find it of different  material as wood,plastic or even carbon.

The reading in the book says this toy was invented to dispel the fatigue used by wealthy people.

This toy traveled around all europe, during the French Revolution the yo-yo took different nickname  as L`emigrette, Coblenz, Joujou the Normandie  etc.

Now after i finished the lesson i can prized the important of this simple toy.
