Why does salt naturally form tiny cubes? It might look like an ordinary kitchen ingredient, but salt crystals are built according to an incredibly precise microscopic structure.

In this episode of History of Simple Things, we explore how sodium and chloride ions arrange themselves, why that arrangement creates cubic shapes, how evaporation affects crystal growth, why some salt crystals become hollow, and why table salt doesn't usually look like tiny cubes.

From ancient salt harvesting to the microscopic geometry inside a single crystal, discover the fascinating science hiding inside something we use every day.
