How do brewers turn a handful of simple ingredients into the frothy, delicious beverage we call beer? Patrick Horn and Bryan Hermannsson from San Francisco’s Pacific Brewing Lab take us inside their testing facility and show us how a new beer is born. Southeast of San Francisco, on the way out to California's Central Valley, thousands of wind turbines dot the landscape of Altamont Pass. Mounted both in rows and individually, machines with large propellers catch the wind, turning round and round at different speeds. Learn how wind energy is generated and stored for use in this most peculiar area, and its impact on living things both near and far. Take to the skies on board the zeppelin Eureka with pilot Andrea Deyling of Airship Ventures and get a crash-free course in lighter-than-air flight: What’s the difference between an airship, a blimp, and a zeppelin? How do they stay aloft? How high and how fast can they fly?
Airship Ventures operates the only commercial passenger airship operation in the United States. To find out more go to www.airshipventures.com. On the cliffs above San Francisco's Ocean Beach perches a landmark observatory—a giant camera obscura. Step inside with Robert Tacchetto and see how this centuries-old technology creates enchanting images of the outside world.
Remember those pneumatic tubes at the drive-up bank? Finessed by modern engineering, this technology is alive and well at Stanford Hospital, where pressurized tubes deliver critical payloads—from medications and specimens to blood for transfusions.
Admit it: Hasn't the Godzilla inside you always wanted to grab the Golden Gate Bridge and shake it silly? Finally, you can. In honor of the iconic span's 75th birthday, Exploratorium exhibit developer Dave Fleming presents a dynamic model of the Golden Gate Bridge. What happens to the bridge during an earthquake? How about strong winds and heavy traffic? The model dances and wiggles realistically, displaying the same vibrational modes and motions that occur in the actual bridge. Take a stroll in Golden Gate Park at dusk and if you’re lucky, you’ll hear a sound perhaps unexpected: the hooting of wild owls. Jessie Bushell of the San Francisco Zoo debunks some common myths about owls while introducing us to several rescued owls currently living at the zoo—from a 3-ounce northern saw-whet owl that was hit by a snowmobile to a 10-pound Eurasian eagle owl confiscated from a smuggler.
The end of an era is near: In movie theaters across the country, film projectors are rapidly being replaced by digital projectors. Paul Clipson, projectionist at the San Francisco Museum of Modern Art, gives us what may be a last-chance look at the tools and techniques—including lightning reflexes—at work in 35 mm film projection.
In this age of iPods and MP3s, the vinyl record (still) stands as an object of curiosity and ongoing admiration. What’s the real difference between a 78 and a 45? Why do they call it “cutting a record” when an album is recorded? Music enthusiast Wade Wright of San Francisco takes us back in time to explain the history and technology of vinyl records.
Beneath the 100-year-old piers that will soon house the new Exploratorium, highly specialized divers are working around the clock to repair and restore a part of the museum that most people will never see: the 1,200 concrete piles—sunk into the bay mud—that support the piers.
