A Demo Every Day: Bringing Fluid Mechanics to LifeFluid Mechanics can seem particularly non-intuitive to the typical student. For example, moststudents will tell you that if velocity increases, the pressure also increases. Preconceptions suchas these can be difficult for students to overcome. Multiple types of exposure to each topic, suchas lecture, problem solving, and reading assignments can help, but demonstrations add anothertype of exposure that is not only informative and visual, but also enjoyable. Demonstrationsduring a lecture period can increase attentiveness and give the students a “feel” for the topic,helping them actually believe the concept that they are learning. These demos also provide anexcellent memory point for the students to reference when they need to use the concept to solve aproblem. Additionally, since both the instructor and student have experienced the demotogether, the instructor can allude to the demo in order to help correct a misconception. Byreminding the student of a demonstration, both student and professor have a starting point fordiscussion. This paper describes in detail over 20 demonstrations and videos that can be used toimprove student understanding and to increase interest in the various topics associated with fluidmechanics. Demonstrations and videos have been developed for all of the topics covered in atypical fluid mechanics course including hydrostatics, viscosity, control volume analysis,similarity, Navier-Stokes solutions, pipe flow, minor losses, and external flow. Most of thedemonstrations are inexpensive and were homemade by the authors and their students; mostvideos are readily available on YouTube.com. The paper will review each of the demos/videos,discuss how they are incorporated into the class, and describe how to fabricate/procure the demoequipment.
