Prince Rupert’s Drop: The Curious Properties of a Molten Glass Blob Dropped in Cold Water

Destin from Smarter Every Day stopped by Orbix Hot Glass in Fort Payne, Alabama to explore a fascinating phenomenon called a Prince Rupert’s Drop. Apparently when molten hot glass is dropped in cold water it forms an object that’s almost completely impervious to brute force, even a sold hammer strike to the center of the teardrop-like shape won’t break the glass. Yet gently cut or even bump the tip of the drop and suddenly the entire thing shatters in an explosive chain reaction traveling at a speed of over 1 mile PER SECOND. Watch the video above to see the effect in 130,000 fps glory. (via the awesomer)
