Powers of ten

Good evening kids, 

I post here a video that I found very cool to explain the powers of 10 and the different orders of magnitude. This is called "Powers of ten". I was recommended by my friend Brianda, who is an architect. The film was made ​​in 1977 by a very famous couple of designers: Charles and Ray Eames.

Have fun.
