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.
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.
