This article describes an experiment, designed by Cindy Henk, manager of the Socolofsky Microscopy Center at Louisiana State University (LSU), that involved collecting and viewing microorganisms in the air-water interface. The experiment was participated by Leesville High School microbiology students. The students found that the air-water interface was a thin biofilm on the surface of still water, composed not of "fish poop," but of a rich variety of living microorganisms. This successful collaboration between high school students and a university researcher had tangible benefits for both parties and has led to an ongoing interaction. (Contains 4 figures.)
