She Sprinkles Salt Onto A Table And Turns Up Sound. The Result Is Breathtaking

This is such a cool experiment!
This is an awesome demonstration of how sound travels at various frequencies. What’s particularly cool is how they illustrate it – using salt. Depending on the frequency that the plate is adjusted to, the salt contorts and conforms to various patterns. The symmetry is breathtaking.
