I really enjoyed watching this in class, but it wont load on my computer at home. It was amazing to see how small the virus was when the bacteria was next to it. I learned that even a small head of a pin could have so many viruses and bacteria on it, so that is amazing how we can get infected so easily with all the bacteria we touch everyday.
