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.

0:04.0 | Moment of um. |
0:06.0 | Moment of um comes to you from APM studios. |
0:11.0 | I'm Mark Sanchez. |
0:13.0 | Oh, man, the Prain's on Zoom Ray is still on the Fritz. I don't get it. I downloaded the newest |
0:21.8 | update, I polished all the lenses I even swapped out the part that makes the cool |
0:26.4 | Zoom Zoom sound effect so why isn't this working and right when I was supposed to go germ spotting with sand and I had my list already with all the microbes I wanted to see. |
0:38.0 | First I was going to look at my yogurt cup to see all the lactobaxylus bacteria. They helped turn milk into a |
0:44.1 | delicious tangy treat. Then I was going to check out the awesome bacteria on the |
0:48.4 | bottom of sand and shoe and inside my dog Ella's mouth. Well, I guess the germ spotting will have to wait. |
0:57.0 | Unless, what if I looked for a lot of bacteria, all hanging out in the same spot? |
1:05.0 | Sure, they're teeny, tiny, incy, beancy living things, but what if they all clumped together? |
1:12.0 | Would there be enough for me to see them with just my eyes? What if they all clump together? |
1:12.6 | Would there be enough for me to see them with just my eyeballs? |
1:16.4 | My buddy Nico was just asking me about this. |
1:19.0 | Hi, my name is Nico and I'm from Gainesville, Florida. |
1:21.7 | My question is, how many germs would have to clump together to be seen without a microscope? |
1:29.8 | You'd really need probably closer to millions to make a visible dot. |
1:35.0 | My name is Daniel Bond. |
1:37.0 | I'm a professor of microbiology at the University of Minnesota. |
1:40.0 | Most bacteria are so small you would need to line up at least a thousand. |
1:46.2 | You'd need thousands of them to fit inside the period at the end of a sentence. |
