Cymatics : Sound Experiments

Cymatics (from Greek: κῦμα "wave") is the study of visible sound and vibration, a subset of modal phenomena. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid. Different patterns emerge in the exitatory medium depending on the geometry of the plate and the driving frequency.
The apparatus employed can be simple, such as a Chladni Plate or advanced such as the CymaScope, a laboratory instrument that makes visible the inherent geometries within sound and music.

We had a cymatic experiment with cornstarch and sound.

It looks different depends on the concentration of cornstarch.
When it is waterly, it shows some kinds of vibrated patterns and when it is thick, it changs the state like a moving dough lump.
The pattern and status were also changed by the sound tone. I could see lower sound generated strong vibration and strong pattern.
And it was interesting to see how the sound looks like.
