Prince Rupert's Drops

One of the coolest videos on glass is the demo on the Prince Rupert's Drop. Molten glass is allowed to drop into a bucket of water and cool to hardness. Once cooled, the drop can be hammered and it will not break. But, if the tail of the drop is broken, the stress in the glass is instantly released and the drop disintegrates into powder. Cool!!
