When we look at a strip of paper with its ends attached, how can we see whether it is a cylinder with two boundary curves or a Moebius Band with a single boundary curve?  We will develop seven different criteria that arise in  undergraduate calculus and the elementary geometry and topology of surfaces.  Physical models and computer graphics images will illustrate the talk.
