Please explain this to me like I’m 5. We just got our microscope, have some prepared slides, focused fine, could see what we wanted, etc.

Moved on to trying cheek swab, see nothing but blue blur, no cells at all. Do I need to let the slide dry before putting on methylene blue? I’ve tried with water, without water, with dye, without dye, with a swab, with a toothpick. Tried with blood because my son’s tooth fell out-still can’t see any cells. Help?

Sorry for the newbie question.
