Remote teaching demo: Make your own Leeuwenhoek microscope for online classes during covid.

This is a demo we normally do live in a second year lab, but it has also worked with high school students. During covid, our lab was online, and I figured I would try this on zoom during class, and it worked pretty well. It's a nice way to breakup a long online class and the students seem to like it. So if you are teaching anything microbiology related and want a little break, this is cheap (free really), pretty easy, and the students like it.
