This “cloud” in the middle of Lake Neuchatel is like a temple of water that surrounds the Blur Building. This building has no walls. It is built of… water that is pumped from the lake and shot as a fog through 31,500 little nozzles. Visitors who enter the Blur Building find themselves being surrounded by an optical “white-out”. They hear only the noise of high-pressure nozzles and are dependent on vision itself as there is nothing to see. If they get lucky and find the second floor, visitors can go to Angel restaurant located above the “clouds” and have a drink of water.
