Singing Ice

Many people don't find a lot to like about winter weather. I'm good with everything about winter except the occasional howling winds, and freezing rain. Even if you aren't a fan of winter weather, there are a lot of interesting phenomena to observe during cold weather. Many of you have probably seen the "throw boiling water into the air when it's -20°F" video as one example. Here is a video I came across the other day which describes the physics behind the phenomenon of "singing ice".  This video was produced by National Public Radio science and hosted on their Skunk Bear YouTube channel. It's a worth a watch!
