How to make Sound come alive?? That is simple. This theory is known as Cymatics. Cymatics is the study of visible sound and visible vibrations. By transmitting sound waves through any sort of medium, we are able to see different patterns emerging. So in this Instructable, I will be teaching you how to actually conduct this experiment.

Step 1: What You Need
A Guitar amplifier
A Tone Generator
A Screw Driver
Amplifier Wire (PC to amplifier)
Step 2: Unscrewing
Step 6: NCH Tone Generator
Step 7: Plugging in the wire.
Note: Higher Frequencies usually require greater amplitude.
Step 8: Powder
I started with a solid medium, powder. Here are the pictures of what happened. I used a Sine Frequency. I set the setting for 60 Hz, 80 Hz, 100 Hz, 120 Hz and finally 200 Hz.
You can see the powder moving due to the pressure differences. Regions of maximum and minimum displacement are made visible in a thin coating of particles.
