Winogradsky Columns Final Day!

Hello! Today I will show you what has happened to the Winogradsky columns. I have extracted a few drops of water from the paper+yolk column, and here are my observations.

P+Y Column Observations

To view the water under my microscope, I used a hanging drop mount. You can see how to make one by reading my previous post "Hanging Drop Mount."

worm-like cell

 In the various water drops I saw some small cells (Fig. 2), long worm-like cells (Fig. 1), and micro-organisms that looked like worms (Fig. 3 & 4). I also saw a cell moving really fast. It could be a paramecium. There were many worm-like bacteria, and a few of the fast moving parameciums. There are also some videos of these organisms below the images.

"Zoo" of organisms. At the top of the image, there

 is a cell that seems to spin when it moves

If you look closely, you can see the long worm
