We believe that nations are little pieces of the puzzle of our world. The lack of any can disrupt the unity. Therefore, we - the Gyöngyösi Berze Nagy János Grammar School in Hungary, the IES Sierra de Guadarrama in Madrid, Spain and the IIS „Basile-D’Aleo” di Monreale in Sicily, Italy - decided to cooperate, learn about each other and shoot some Puzzle films together to show the importance of what we are doing and what we have achieved in the field of science&technology, art and society.
