The Sound of Freezing: Explained!

For the last few months I've been experimenting with ways to grow ice crystals, and while there's a lot to come on that front (Subscribe for the rest!), welcome to Episode 1: The Sound of Freezing! The vacuum-evaporation setup I used to freeze water in this video was one of the first I tried, and it wasn't until recently I realized that I had inadvertently recorded the SOUND of freezing water - I didn't think it was possible (and I thought freezing water wouldn't make a sound). In this video I explain dendritic growth of crystals, freezing water ice from supercooled liquid, and propose a source for the crackling noise that seems to accompany the formation of ice crystals!
