The use of Chladni plates can make a wonderful demonstration but can be rather expensive for equipment that may have limited use in the average classroom. This video shows how I set up the experiment using a free online tone generator on my computer, a discarded amplifier, a mechanical driver easily made from an old discarded speaker and some plates that were cut out of sheet metal. This video was made with very little practice, the plates were quickly cut and not squared or with the hole not being exactly centered. I'll be experimenting with other materials and shapes to see what additional patterns can be formed. For now, this is a good start to my investigation.
