Hear the Otherworldly Sounds of Skating on Thin Ice | National Geographic

  • Published on Feb 9, 2018
  • This small lake outside Stockholm, Sweden, emits otherworldly sounds as Mårten Ajne skates over its precariously thin, black ice. “Wild ice skating,” or “Nordic skating,” is both an art and a science. A skater seeks out the thinnest, most pristine black ice possible-both for its smoothness, and for its high-pitched, laser-like sounds.

    Black ice is recently frozen, and can be as thin as 2 inches and still support the weight of a skater. Like a dome or arch, the support comes from the sides rather than the top, and the water underneath prevents the ice from breaking. But, experience and careful advance planning are key. Factors including temperature, atmospheric conditions, and even satellite images of the Earth’s surface are considered. It’s complicated, but appealing to mathematicians like Ajne. Even with preparation, there’s a risk of falling in… So it’s best done in groups, for safety.

    Black ice is recently frozen and can be as thin as 2 inches! Do you think you want to try Nordic or wild ice skating? Make sure to try in groups if you do!

      lol the guy in the video says 45mm is more than enough in the video, and NatGeo is going to somehow trump that dudes experience and tell everybody something different

      We, in the Netherlands, need 15 cm for the Elf Stedentocht, a famous ride in Friesland. The last was in 1997, so 22 years ago. We need freezing cold weather. Sorry for my english, I'm dutch ;-)

    As a dutch person, I know, if you hear these noises, you need to start skating quickly. Allthough these noises appear here when the ice is much thinner because it covers a much smaller area, if you hear these noises you could actually be in serious trouble here.

    I already stepped on ice layers like 50-70mm thick. With gas bubbles inside and with my weight of 110-120kg. There was not any reaction of the ice, not at all after jumping on it. So 45mm have to be very strong, especially for the thin rider on it.... I think this video is not dangerous at all.
