These videos aren't just colorful and fascinating — they're also educational. They're made using just some speakers and a non-Newtonian fluid, and they can teach us important principles in physics.
There are many examples of Faraday waves, the rippling patterns formed when a fluid interface becomes unstable under vibration.These videos feature several examples of Faraday waves, the rippling patterns that appear when the surface of a fluid becomes unstable due to vibration; while the tiny droplets that break off from strands of dancing liquid are the result of Plateau-Rayleigh instability.
