Prestvannet lake is a hot spot to enjoy aurora in different seasons.By analyzing the site , we finally find the best way for the museum that can both serve residents and travelers.We expect that the museum can construct a new viewing experience by using the same principle as scientists and different perspectives to enjoy the beautiful aurora under the water.
