This post has information and video links about the effects of sound on form of solids and liquids.

From Wikipedia:

Cymatics is the study of wave phenomena. It is typically associated with the physical patterns produced through the interaction of sound waves in a medium.

A simple experiment demonstrating the visualisation of cymatics can be done by sprinkling sand on a metal plate and vibrating the plate, for example by drawing a violin bow along the edge, the sand will then form itself into standing wave patterns such as simple concentric circles. The higher the frequency, the more complex the shapes produced, with certain shapes having similarities to traditional mandala designs.

A demonstration of “charging” water in a singing bowl. By rubbing the beater around the bowl for a few minutes, the water begins to pop up, and bubbles are formed. The water isn’t hot. Also if you stop for a while after you get the water in sync vibrationally and then start rubbing the bowl again, it will starting popping and bubbling much quicker than the first time. I saw a video online of someone doing this and I had came across one of these bowls myself a year ago and tried it myself. The older singing bowls were made with different mixes of metals and from what I have read from people that know much more about them than I do, don’t drink water from them as some of the heavy metals could get into the water and make you sick. After the below video experiment the mat that the bowl sat on was lightly stained the color of the bowl. If you try this experiment yourself and make a video of it, please embed the video in the comments section below. Here is my experiment without any cuts:

I love dogs and I enjoyed making the video above. It was a FUN event and I hope more people around the world start having similar events.
