San Francisco has more restaurants per capita than any other U.S. city, producing tasty meals—and thousands of gallons of used cooking oil. See how the SFGreasecycle program is turning this grease glut into fuel for the city's bus fleet.
Originally produced for NOVA in 1982, Jon Else's film, "Palace of Delights" takes a look behind the scenes at the Exploratorium in action. This After Dark, we celebrated the allure of real rocks, paper, and scissors, and explored some surprising theories surrounding the game. Using the official rules of the World RPS Society, we hosted our own Rock Paper Scissors tournament. Dr. Frank Oppenheimer discussing the origins of the Exploratorium Explainer Programs. The waters of San Francisco Bay are making a dramatic comeback as workers slowly remove a 1950s-era paved deck from between Piers 15 and 17 on the historic Embarcadero, at the site of the Exploratorium’s new home. In early November 2011, the east bridge, dedicated to the Fries family by San Francisco philanthropist Bill Fries, was put in place, connecting the terrace of the new Pier 15 Bay Observatory building to the adjacent side of Pier 17. When the museum opens in the spring of 2013, this bridge will offer prime views of the City and the Bay. At the Exploratorium, we are always experimenting. In this video, watch a close-up vantage of a bicycle trip along Crissy Field in San Francisco's Presidio. Join the Exploratorium crew on a visit to the Scripps Institution of Oceanography, where we will learn more about the ecological impact of plastic debris in the North Pacific Gyre.

Why do they sometimes capsize? Exploratorium Senior Scientist Paul Doherty dives deeper into the physics of the America's Cup catamarans in "Sailing 102: Tip Don't Flip!" There are green sea turtles in San Diego Bay? Where did they come from? Do they really live over 100 years? Why is it important for scientists to keep track of these giant creatures, and how on earth do they do it? In this interview with ecologist Tomoharu Eguchi (NOAA Marine Fisheries Service) and ecology graduate student Sheila Madrak, we meet the sea turtles and explore these 'big' questions. The Southern California Coastal Ocean Observing System (http://sccoos.org/) gathers live data about winds, waves, surface currents, temperature, and water quality, and makes it available to everyone. In this piece, Oceanographer Art Miller tells us about this system, and about how America's Cup sailors can use this kind of data and modeling to improve their race performances.
