Have you ever seen something so delicate yet incredibly resilient? If you haven't, let me introduce you to the fascinating world of Prince Rupert's Drops. These unique glass structures are created by dripping molten glass into water, resulting in a drop with an extremely high compressive stress on the outside and a tensile stress on the inside. The result? A glass structure that can withstand a hammer or even a bullet to its tip without breaking, but shatters dramatically if the tail is even slightly nicked.
