The Invisible World

This interesting video is an excerpt from the documentary “The Invisible World.” Through the use of scanning electron microscopes [SEM], it shows an amazing world of microscopic organisms living on the surface of our bodies. Each of us is the keeper of a huge invisible zoo, and some of the creatures are permanent exhibits. At any given time there are as many creatures on our body as there are people on earth.
