Naked theory sounds like this. The Nigardsbrin glacier is the tongue of the Jostedalsbrin glacier, the largest in continental Europe. In general, glaciers are huge streams of compressed snow. Their power increases due to heavy snowfalls and decreases due to snowmelt, evaporation and wind erosion. The glacier seems blue inside because the thickness of the ice absorbs primarily the rays of the red spectrum, and only blue rays penetrate to the greatest depth. Practice will consist of short enthusiastic phrases and interjections.→
