I can only imagine the number of earplugs used during the making of this ad for Sony's MHC-V7D speaker. The video illustrates what sounds look like, via a series of Cymatics experiments. If the MHC-V7D can make water and sand dance, imagine what it will bring to a house party, aside from tinnitus? It's interesting to watch, from a scientific perspective. First, a petri dish filled with vodka is placed on a sub-woofer, where the music makes the liquid move in mysterious ways. Next, a thin metal sheet covered with sand is attached above the speaker, creating interesting patterns that change with the music. Lastly, three colors of paint are placed on the woofer and, needless to day, dance and jump around. See it here, created by UNIT9.
