I thought that the videos were extremely informative. Although I was already aware that life does exist on such a small scale, it is a difficult thing to comprehend. The visual aid of the videos helped me to grasp the concept of life on a molecular level. One thing that really amazed me and stuck out in my mind was the clip about the propeller on the end of the cell. It is astonishing that such a small machine exists on such a small scale and even more incredible how efficient it is.
