Running Time: 00:06:00
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.
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.
