Extension

A quack is often thought of as a person who falsely promotes medical products or services. Throughout our history there have always been “quacks” selling the public things that would never work such as oil that can cure cancer. Some products are based on partial truths and reference false authorities or have testimonials from “cured” people. Discuss in your group or as a class what items you have seen advertised that might not be totally truthful. Come up with your own quack device and construct a model. Design a full-page advertisement for a magazine or newspaper. Prepare a one-minute television commercial or a five-minute infomercial. Present your ad and commercial to the class. Discuss how quacks can originate superstitions.
