As ridiculous a that title might sound, it’s a treat for the ears. Even though it’s been a year since scientist Peter Neff shared this great outtake from an Antarctic expedition, we give it a listen at least once a week. When that small ice chunk falls 90m (295ft) through the ice, the rattle is great but the old western shootout “ding” at the end is perfect. Check out more about the Ancient Ice project from the University of Rochester for some great behind the scenes shots on life on Antarctica.
