Everything vibrates to a certain frequency. If you put different substances on a speaker, they will react in different ways.
This video shows how a number of different everyday substances, such as Cheerios in milk, Coke, ketchup, vegetable oil, Purell gel, paint, talcum powder, M&Ms, colored sprinkles, a raw egg, and water react to the sound vibrations from a speaker.
Here’s what these substances look like as they react to the vibrations from the speakers.
Cheerios in milk
It looks like this is all about “Good, good, good, good vibrations.” Anyway, although the effects are stunning, I’d say the speakers were pretty well trashed making this video.
