Video: I don't care that I supposedly understand how vinyl records work because I still totally think they're the work of at least some low level sorcery. Trapping sound and music and voices?

The video by Applied Science also delves into how they managed to capture the footage using an electron microscope. A little bit technical but really interesting stuff.
