Oko company designs a water bottle fitted with a filtration system that instantly turns cola and other soft drinks into clear and colourless water. The filtre is inspired by a NASA technology used on the International Space Station. It was developed by NASA to ensure that astronauts in space station drink pure, fresh and clean water.
The video footage shows the bottle being put to the test. It is being filled with brown Coca Cola which, after being poured through the special filter cap, looks exactly like water. For video scroll down to bottom.
