Watch styrofoam dancing to sound waves

Put your hands in the air and wave them like you just don’t care.

What looks like a dubstep rave of little ghost people is actually styrofoam dancing to sound waves in a massive plexiglass pipe known as a Kundt’s tube.

In 1866 German physicist August Kundt constructed the experimental acoustical apparatus to measure the speed of sound in a gas or a solid rod. Said Kundt, “A physicist must be able to saw with a file and to file with a saw.”

The faux mosh pit is the result of a process called “sound looking” which demonstrates what audible vibrations or acoustical forces may actually look like.

No one can doubt that life moves to fascinating rhythms & vibrations.
