Italian designer Emanuele Pizzolorusso presents a smart project that could also be very useful. Rome is a city full of walking paths and full of tourists, and it's hot during the summer, right? What these tourists might not be familiar with, is that together with its heritage of ruins, palazzis, museums, churches and piazzas, the Eternal City is well equipped with public fountains, historically the mean used to distribute drinkable water to the folks. From the famous Fontana di Trevi down to the most humble "fontanelle", there is absolutely no reason for a tourist to bring around – and then waste – plastic bottles containing water. By marking on the map of the centre of Rome the sources of public water and then printing it on a soft, multi-layer package that doubles as flask, the designer opens the way to the massive use of an important resource currently not enhanced by the tourist authorities.
