This gives new meaning to “skating on thin ice.” In Sweden, a filmmaker named Henrik Trygg likes to take his chances skating on pristine sheets of black ice, measuring only five centimeters/two inches thick. It’s a risk. A natural thrill. It’s also quite a sensory experience. Just listen to the “high-pitched, laser-like sounds,” of which sci-fi films could be made.
Watch Trygg’s film, “The Sound of Ice,” above. And, below, a version annotated in English by National Geographic.
