Meet Destin from Smarter Every Day and discover the amazing properties of the Prince Rupert's Drop! What happens when you drip molten glass into cold water? The glass forms a tadpole structure (a bulb with a tail) with a very peculiar strain structure at the inside: the drop won't break if you hit the bulb with a hammer  but even a small damage (a swing or tiny crack) on the tail will cause the whole structure to break... exposively ! Take a seat and be ready to be fascinated! Source: SmarterEveryDay Channel wikipedia
