iQLANDIA is a four-floor hands-on science center in Liberec, about an hour and a quarter by car from Prague. Ten interactive exhibitions cover space, math, water, the senses, the human body and old inventions, and a fire tornado swirls in the Elements hall. The iQPLANETARIUM shows dome films in the same building, and kids can combine both on one ticket.
