Do you know there’s a piece of glass that can stop a bullet but breaks with a single touch? It’s called a Prince Rupert’s Drop! When hot glass falls into cold water, it cools so fast that the outside becomes super hard — stronger than steel! You can even shoot it, and the bullet will break instead! But here’s the crazy part — if you just flick its tiny tail, the whole thing explodes into dust in a second. How can something this strong also be so fragile? | Epixology

More footage showing just how strong a Prince Rupert's drop is... As a reminder: a Prince Rupert's drop is a teardrop-shaped object made by dripping molten glass into cold water, causing it to cool rapidly and trap internal stresses. The outer layer cools first, creating compressive stress, while the slower-cooling inner core generates tensile stress. This stress distribution makes the bulbous head extremely strong, capable of withstanding substantial force, but the tail is highly fragile. If th
