“…it’s so simple!” is the newest project of Innovation Centre Mill of Knowledge. This modular and mobile exhibition is divided into four thematic zones (modules). Each one is composed of 6 or 7 exhibits. The passage through the zones will constitute a journey through the world of riddles and puzzles (in zone Mr.Brainy) which shape and develop the ability to think logically, to fill and understand the simple physical laws (in the second zone called Mechanical Playground). In the third zone Think, understand, do the visitor could construct and solve mechanical and creative issues independently. These knowledge and skills are essential for the creation of modern technologies, which the we could see and use in the last zone TechnoWorld. So after this journey through the exhibition we can say finally “…it’s so simple!” to use our brain and mind, our hand and imagination to be a part of the modern world.
