First, we started with water. Around 60 hz, the water suddenly transformed, with numerous polygons disturbing the previously static surface. We assumed that the shapes we got were a product of a standing wave for, at certain frequencies, the beaded polygons seemed to stand still. Doubling the frequency, 120 hz, seemed to produce similar results, but with smaller polygons.
In order to better illustrate this, we dropped a little oil in the very center of our water. We immediately noticed that the resonant frequencies of the oil was dramatically lower than that of water. At 40 hz, for instance, the oil changed, producing a circular standing wave. The water was not effected by such a low frequency. Taking the frequency up to 60 hz, the two mediums switched, with the water now being effected but the oil remaining stationary.
We got bored with water.
Next, we combined oil and vinegar. Besides the obvious effect of having a more colorful substance, we were tickled by the mixing of the two liquids, the volatile nature of the vinegar within the oil, and the overall splatter effect of the two substances. Again we saw the oil create a circular standing wave, but it was a little lackluster. Thus, we moved on. Heads and swords held high.
