Fisher Bay Observatory Gallery 6, Mezzanine
Uncover the history, geography, and ecology of the Bay Area.
Aeolian Landscape
Aeolian Landscape presents a swirling storm of sand inside a large chamber covered by a plexiglass top. A knob on the top of the exhibit rotates a sturdy fan set in the base of the chamber.
Avalanche
Does the sand all pile up in the same way?
Braided Stream
Air—not water—erupts through fine powder to sculpt these roiling streams.
Drip Chamber
Liquid glycerin drips down, creating unique shapes and shadow patterns.
Where: This exhibit is not currently on view.
Fluttering
A piece of fabric undulates in complex ways.
Icy Bodies
Like comets, these chunks of dry ice slowly disintegrate as they move, leaving a visible trail of condensed water vapor.
Illuminated Fog
Swirling, drifting, billowing movements of air reveal themselves in the fog.
Liquid Litmus
See the chemical reactions taking place in an electrolytic cell, as electricity flowing through a tank of salt water and pH-indicating dye creates zones of acidic (yellow) and basic (blue) solutions.
Rift Zone
Bubbling sand evokes a geothermal landscape.
Seismograph
This seismograph is an earthquake detector that records the up-and-down motion of the ground—whether made by tectonic activity or by you.
