The Star Wars Sound of Singing Ice

When Cory Williams moved from California to Alaska in 2014, he discovered an unusual natural phenomenon: a singing frozen lake. He tried skipping rocks across the icy surface of Edmonds Lake, near Anchorage. His YouTube video of the laser blaster sound that the lake made has been viewed 11 million times.

This year, Williams returned to Edmonds Lake and made another discovery. The lake was singing on its own. Why? And how? The latest video from Skunk Bear, a science youtube channel, reveals the origin of that iconic sci-fi sound effect and explains why it can be heard every year in the cold north.

Here is the video. Turn on the subtitles if you need them.
