Ice can make all sorts of sounds: cracking, crackling, musical booooooms… and that pew! pew! Star Wars blaster sound. How? In this episode of NPR’s Skunk Bear, we learn about acoustic dispersion and how the phenomenon can create that familiar movie sound effect with the help of a frozen lake… or with the slinky that you might have around the house. Watch this vid, then try making the sound yourself.

Related ice sounds: Crackling ice stacking on the shore of Lake Superior and Ice Drumming on Lake Baikal.

Plus: The Waterphone, The Secret World of Foley, The Inverted Glass Harp, more frequencies and vibrations, and more smart from Skunk Bear.
