How do crystals work?
Many crystals have signature shapes— like the cascade of pointed quartz or a pile of galena cubes. Every crystal's atoms have a defining feature: their organized, repeating pattern. The pattern isn't restricted to minerals- sand, ice, metals and DNA also have crystalline structures. So what causes them to grow into these shapes again and again? Graham Baird dives into the unique properties of crystals. [Directed by Franz Palomares, narrated by Addison Anderson, music by Carlos Palomares].
