A man caught the moment in slow motion video that a piece of glass known as the Prince Rupert's Drop withstood a bullet fired at close range.
Destin Sandlin, an engineer who has a YouTube channel called Smarter Every Day, likes to experiment with trying to destroy the almost indestructible (unless its tail breaks off) tadpole shaped glass piece known as the Prince Rupert's Drop.
Because of the way tension is distributed throughout the glass, the head of it can withstand extremely high stresses, such as hammer blows or Hydraulic presses, while it will normally the entire glass shatter if the tail is broken, or even just wiggled.
