Leave the culture is a dark room for a few days and wait until a brown scum forms on the surface

a dropper, place a few drops of the sample on a microscope glass slide (a sample of pond water or a small sample from the culture)

Gently cover the sample with a cover slip and mount on the microscope stage for viewing
