Come out to play on the concrete slides at Seward Street Mini Park in the Castro. A series of speed tests guided by physicist Paul Doherty takes on the question asked by sliders everywhere: How can I go faster?
Urban environments like San Francisco are full of mysterious natural and human-made phenomena. Why are there so many one-footed pigeons? Where does the sewage go? Why is our “summer” in May and September? The Exploratorium is “taking it outside" to explore these and other questions in engineering, ecology, optics, waves, geology, architecture, weather, and more. Look for new episodes once a month.
