How many germs could we see without a microscope?

There are so many bacteria in the world that we still haven’t discovered them all! But because bacteria are so tiny, they’re really only visible with the help of a microscope. But what if lots and lots of those teeny tiny bacteria got together in a clump? How many would have to pile together before we could see that pile with just our eyes? We asked microbiologist Daniel Bond to help us find the answer.Got a question GERM-inating in your brain? Send it to us at BrainsOn.org/contact, and we’ll help micro-SCOPE out an answer!
