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.

I'm curious if the flame is sufficiently hot to melt the standard borosilicate capillary tubes? In other words, that wasn't soft flint glass that you were using?

[@Anime_games-_-XUnknown]

What did you use for glass?

What is the diameter of the lense?
