Abstract. Students in general chemistry often have trouble because not only do they not understand the concepts, but they also do not understand the questions the concepts explain or their significance. I have developed a simple classroom demonstration which illustrates the idea of the atom and continuous versus discontinuous matter. The demonstration also can be used to introduce the concept of wave-particle duality.
