Sound Waves Visualized with a Chladni Plate and Colored Sand [Video]
This eye catching demonstration combines a Chladni Plate, four piles of colored sand, and a rubber mallet to great effect–watch as the plate vibrates pattern after pattern into the sand.
A Chladni Plate, named after physicist Ernst Chladni, is a steel plate that vibrates when rubbed with a rubber ball-style mallet. Different size balls create different frequencies and each frequency creates a different pattern in the sand placed atop the plate. Watch the video above to see how rubber balls, large and small, change the patterns.

Beautiful!
Would make for a great screen saver, too!
They are great magics to be seen and enjoyed. However it did not add to my knowledge or understanding. I am interested in know how to do it myself, if possible.
