About

Once a year, Lisbon's natural history and science museum and the Botanical Garden next door fill with researchers sharing their work at over a hundred hands-on stands. Past editions have had telescopes for stargazing, robotics, bioplastic-making and an escape room in the old chemistry lab. It suits curious school-age kids best. Toddlers may tire of the evening crowds.
