Hey kids! Go rest your hands on a speaker playing loud music. Feel the sound vibrations? Good. Now you might want to adjust your volume for this one.Sound frequencies produce a variety of increasingly intricate resonance patterns. And if you sprinkle... sand or salt on a metal plate that is vibrating from these sound frequencies, you can see the patterns.
Sand on a rectangular metal plate shows the resonance patterns at specific frequencies of oscillation.
