Tekniska is a sprawling wonderland of interactive science and technology exhibits. One of its biggest drawcards is Cino4 (adult/child Skr80/40), Sweden’s first '4D', multisensory cinema. The 'Teknorama' is a vast room of kinetic experiments and stations designed to do things like test your balance, flexibility and strength. In one corner is a dark and genuinely scary mining exhibit. There’s also a model railroad, a survey of inventions by women, and a climate-change game.
