Chladni Singing
Sand scattered on a large metal square vibrates and jumps in response to the sound of your voice. When you hit just the right note(s), the sand spontaneously migrates into elegant geometrical patterns.

Coupled Pendulums
Start one of these two pendulums swinging and soon you’ll see the other pendulum start swinging, too. Keep watching and you’ll see the two pendulums take turns, alternately swinging energetically and coming to a near standstill.

Energy from Death
A decaying carcass makes a perfect meal for an assortment of scavengers, including the dermestid beetles you can see in this exhibit. As they feast on these carcasses, the dermestid beetles and their larvae get their energy and nutrients from the dried flesh, skin, and other tissues.

Humming Plates
Sand reveals vibrations that are normally invisible.
Where: This exhibit is not currently on view.
Wave Organ
Sound at this wave-activated acoustic sculpture is created by the impact of waves against the pipe ends and the subsequent movement of the water in and out of the pipes. The sound heard at the site is subtle, requiring visitors to become sensitized to its music, and at the same time to the music of the environment.
