Have you ever wondered where your plastic bottle goes after you toss it in the recycling bin? Take a little trip with us to the San Leandro Waste Management facility, where Rebecca Jewell tours us through the complex world of residential recycling. In an unlikely corner of industrial southeastern San Francisco, a herd of 60 goats gambol on a 10-acre site ringed by a rail yard and a cement recycling plant. Meet the movers and munchers behind City Grazing, a local “rent-a-goat” service that provides an ecological alternative to lawn mowers and herbicides.

Does this type of self-talk serve any purpose? Recent research suggests that it does, helping us to build motivation and control impulses. Here, one man confronts the power—and the limitations—of his inner voice. Throughout history, tattoos have represented conquests, coming of age, religion, spirituality, art, and even punishment. Today, tattoos are alive and thriving as a form of personal expression. How have modern techniques changed this art form? What are best practices in tattoo creation and care? Why are tattoos permanent—and when are they not? Join us as we "talk tat" with artitsts Suzanne "Fishy" Shifflett and Tanya Wischerath of Modern Electric Tattoo in San Francisco. Monday is spiky. The number nine is orange. The letter F smells like smoke. Roughly one percent of people experience such blending of the senses, known as synesthesia. In this episode we meet Bryan Alvarez, a doctoral candidate at the University of California at Berkeley, who is researching the neural mechanisms of synesthesia in an effort to explain why only some of us experience this cognitive crosstalk.
Ever wondered where that crust on your car battery comes from? Exploratorium staff member Chuck Mignacco explains galvanic corrosion and the basics of battery maintenance using a time-honored miracle solvent: Coke. Watch for a surprise guest at the end of the video. Join Exploratorium educator Ken Finn as he unlocks the mystery behind the black sand (a.k.a. magnetite) at Ocean Beach. This piece explores the origin of magnetite in the Sierra Nevada mountains, its journey down the Sacramento and San Joaquin rivers to the Bay, and the interesting physical properties of this mineral, plus some fun things you can do with it. Obsidian points, Spanish terra-cotta tiles, Prohibition-era liquor bottles—history lies buried underfoot in the Presidio, one of the earliest settlements in San Francisco, occupied in turn by the Ohlone Indians, Spanish, Mexicans, and the U.S. Army. Archaeologist Kari Jones shares tales of recent digs and discoveries in this national park, and explains why most artifacts are dug up only to be reburied. Goerte once described architecture as "frozen music," observing their common foundation in mathematics, geometry, and aesthetics. But what is the sound of a skyscraper? A warehouse? A bridge? Here we explore the connections between architecture and music, juxtaposing San Francisco buildings with musical compositions influenced by architecture. This experimental segment of Science in the City asks more questions than it answers. Like the Golden Gate Bridge, San Francisco's cable cars are world-renowned as emblems of our city. Join us for a ride down Hyde Street as we investigate what makes these historic cars go—and more importantly, stop—on the steep hills of San Francisco.
