Museo de la Ciencia y el Cosmos

If you enjoy pushing buttons and musing on the forces of nature, you'll have fun at this museum, which introduces key scientific concepts in an engaging and thought-provoking way. Located about 1.5km south of Plaza Adelantado and easily accessible by the tram to Santa Cruz (which stops right outside), it also has a planetario (planetarium), so you can stargaze during the day.
