The drinking water provided for San Francisco and many nearby communities is among the purest in the world. Located high in the Sierras, more than 200 miles away, Hetch Hetchy reservoir holds most of this water which is fed by springtime snowmelt via the Tuolumne River. The system for delivering that water is almost entirely gravity fed, requiring almost no fossil fuel consumption to move water from the mountains to the tap. Take an exclusive tour with the San Francisco Public Utilities Commission (SFPUC) as they lead us through this unique system and address the current drought and how to conserve water.

Immerse yourself in visual storytelling that extends the possibilities of cinema. See aspects of film rarely displayed: unusual film formats with Dino Everett and an insider view into projectionists’ techniques with Paul Clipson. Enter worlds created by Elise Baldwin—investigating collective memory—and by Wet Gate, a 16mm projector–playing ensemble. Experience Thad Povey and Mark Taylor’s multiturntable record player, the realization of their near-identical dreams, and Tooth’s multiprojector dreamscape installation. Play with the Eunoics Light Club as they summon seemingly living forms using lenses, filters, and mirrors. Debate the merits of short films with Brian Darr and make your own cinematic toys and sound effects. Finally, make your exploration of film not just figurative but literal by seeking—and finding—four films shown in the museum’s out-of-the-way corners.

On February 26, 1998, a total solar eclipse darkened skies in a swath stretching from the Pacific Ocean to the Atlantic, across the Caribbean. From the island of Aruba, an Exploratorium team presented a live Webcast of this celestial event. At the time, Webcasting technology was in its infancy, and this first live Webcast ever of a solar eclipse broke existing records for the number of viewers. Watch the archived Webcast here, or just click on the images below for still photos of eclipse highlights.

A dozen whales, different species and ages, have washed up recently on nearly 300 miles of Northern California coastline. While this is not a record, it's still alarming. Why is it happening? Bay Area scientists are considering factors such as environmental changes, food distribution, shipping, ocean currents, and predator behavior. Meet staff from the California Academy of Sciences, Mission Science Workshop, and the Exploratorium, and explore evidence leading to and hypotheses about these tragic events.

Exploratorium Global Studios worked with TÜBITAK, the Scientific and Technological Research Council of Turkey, to plan, design, and support implementation of the Kocaeli Science Center (KSC) located in the historically significant SEKA Factory site, approximately 100 km southeast of Istanbul. In addition to completing the master plan for this new science center, Global Studios provided architectural review, detailed environmental and exhibit design, and fabrication oversight. The completed design package included 200 exhibits in 3 main galleries and an outdoor area. Global Studios also provided a series of professional training and program development workshops for KSC staff in Turkey and on the Exploratorium campus in San Francisco.

Experimental physicist Carl Haber restores antique audio recordings too old, fragile, or damaged to be otherwise replayed—including recordings made in wax, soot, and foil. Using optical scanning technologies from his work at CERN in Switzerland, Haber has recovered and preserved a diverse collection of deteriorating sonic artifacts, voices from the past that otherwise would have been lost.

With the ever shifting boundaries between humans and wildlife in the Bay Area, the daily routine for many has it's challenges and rewards for all involved. Based on biological studies and direct experiences, we focus on a few of our favorite neighboring species who interact with us humans, and our way of life, in more ways than you may think.
