Powers of Ten

I remember seeing something similar to this when I was in tenth grade. It was a short film that started out in space and the perspective reduced by a power of ten until it got down to the molecular level. It was one of those things that I will never forget from school. I found a website that shows something similar that begins at 10E23 meters (the vastness of the universe) and goes down to 10E-16 meters (examining quarks). This is a great teaching tool. Here is the link to Powers of Ten.
