Watch this mercury drop suspended on Teflon as the surface is
vibrated at specific amplitude and frequency. The frequencies
create different modes of resonance, because the molecules
vibrate faster when shaken at a certain speed.  This is similar
to how your glass of water will form ripples if exposed to the
right sounds (like the thumping of a T-rex walking toward your
car). The vibrations from the sounds moves the molecules of
mercury and form them into different geometric shapes.  At mode
two, the mercury switches between two elliptical shapes that are
perpendicular to each other.  In mode three, the form has three
corners, and the mercury blob switches between two "directions."
The cycle continues, four, five, six, seven and eight cornered
shapes. When subjected to a random vibration, one that didn't
resonate with the liquid element, chaos ensues.  The noises used
in the video are too low in frequency for us to hear, but they
are on par with the very deep tones elephants use to communicate
long distances.
