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

136185 ratings | 5662637 views
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. ➡ Subscribe: http://bit.ly/NatGeoSubscribe About National Geographic: National Geographic is the world's premium destination for science, exploration, and adventure.

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!

I feed off the risk, so I do it solo with heated blades.

I don't think they mean everyone on the ice. More like take turns at different spots. Need a couple of people just in case.

What is 2 inches? Is that international system? Do yo take your position on Paris meridian? What refer the 0 in Fahrenheit scale? Should we remind Mars Climate Orbiter or Air Canada 143?

It’s not that rare or difficult to find these sounds. Lake Lowell in southwestern Idaho produces these same sounds well into winter, simply by skipping rocks across the surface of the ice. Nice dramatic effects with the complex mathematics and satellite technology required... lol. NatGeo has fallen so far from its origins...

It's just too much fun to stop. Have to wait for darkness to begin obscuring your visuals of the ice.

I rememember such sounds with fondness, recalling my youth in a New England town.

Those sounds are the sound of ice cracking and settling. Only reason he doesn't fall through is the speed at which he travels

This is the first time I've seen YouTube electronics mess up, with the added bonus, of seeing something National Geographic that not only is wrong, but is poorly produced. I typed my comment about the ice sounds I heard first, but it says "1 second ago". The second comment I typed says "55 seconds ago". I also know I typed them apart further than that. They do display in the order I typed them. okay... okay... you can say get a life if you want to.

Here in Ontario, black ice is thin ice that freezes on roads that you can't see, blending with the pavement. I can't imagine new ice anywhere being anything other than completely transparent, unless someone put black dye in the water. They should have touched a mike to the surface, getting far more sounds, and much louder.
John Watt (1 day ago)
On of the most amazing and loudest sounds I ever heard was caused by ice. The ice on the Welland Canal was over five inches thick, hiking along there after the sun went down. There must have been a big Niagara Falls hydro water diversion that lowered the water level. All of a sudden I heard a big crack that sounded louder than the cannons at Fort Erie, and it kept going along the side of the canal, fading into the distance, miles away. Incredible! I went down to take a look and the ice along the bank had sagged down onto the stones, with a big crack between it and the ice that was still floating on the middle of the water. So I took a drink.

Just sounds like normal ice. Plus, 1.75 inches of ice is not safe.

He uses math and sometimes satellite imagery to plan out his routes. Bull to the poo, bro puts his skates on and skates while hoping for the best. Get over yourself Nat Geo. But great video nonetheless

That’s insane when you see the whole surface bend and flex

If you fall the ice will break and that's the tea
I’m so heavy that I’d probably break the ice just by looking at it

1inch = 2,54cm -> 2inches = 5,08cm, he measures the ice to be 4,5cm thick?! Thats another 11% < 2inches. Do you even math?

Considering you wait until the depth is acceptable to such weight. Otherwise you hear terror

Like stones being rubbed together and slightly chipped away, with waves rising and receding in a shallow water to create the back and fourth of breezers, the crack of dead branches hitting a wood hut along with a swift snap of smaller, brittle branches, and followed by a gust of wind whipping through a willow tree?

I believe at 3 inches ice is strong enough to support a vehicle.
