Yes, the geometry of ice is fascinating. Each water molecule aligns with hydrogen bonds, forming a crystalline lattice. Temperature, pressure and impurities dictate the final shape. Let me show you the basic crystal habit.

The most common shape is the hexagonal prism; it looks like a tall, six‑sided column. If you cool it very fast, the ice branches into a dendritic tree, like a snowflake. At lower pressures you get needle‑like crystals that stack into columns. Each form comes from the same hydrogen‑bond lattice, just arranged differently by temperature and pressure.
