In the demonstration in this chapter, a person holds a large foam board and a small brass weight to compare their respective weights. After hefting both objects for a few moments, the person is asked to determine which is heavier. The obvious answer is the brass but when the objects are compared using a balance or a lever, the startling results show that the foam is the heavier object. This demonstration is appropriate for students at all levels.
