Self-Filling Water Bottle Converts Humid Air into Drinkable H2O

Kristof Retezár, a designer based in Vienna, invented a device that can extract humidity from the air and condense it into drinkable water. The handy gadget, dubbed Fontus, can be attached to a bike so that cyclists can generate water during long-distance rides through the countryside, where pit stops may be few and far between. Fontus works using the basic principle of condensation, which can be easily demonstrated by taking something out of a refrigerator (for instance, a can of soda) a
