Why tempered glass breaks into safer pebbles
HERE’S THE INTERESTING PART
Instead of causing catastrophic injury in a crash, car windows are specifically engineered to politely explode into dull pebbles. During manufacturing, the outer surfaces of the pane are rapidly cooled while the core stays hot, locking extreme internal stress into the material. The moment an impact manages to pierce the surface tension, the whole sheet instantly detonates into safe, chunky squares.
One discovery leads to another.
