Hands-on science centre in the town where Tesla went to school.
Nikola Tesla went to secondary school in Karlovac, and this centre picks up exactly there: instead of glass cases with warning signs you get interactive stations about electricity, magnetism and Tesla's ideas. You press, crank and experiment yourself until the physics suddenly clicks. Fun for kids and for anyone who only knows Tesla as a car brand.
