Prince Rupert's drop

n
1. a glass bead in the shape of a teardrop, a by-product of the glass-making process, formed by molten glass falling into water. The body of the drop can withstand great force, for example a hammer blow, but the whole will explode if the tail is nipped or the surface scored
2. (General Physics) a glass bead in the shape of a teardrop, a by-product of the glass-making process, formed by molten glass falling into water. The body of the drop can withstand great force, for example a hammer blow, but the whole will explode if the tail is nipped or the surface scored
[C17: thought to have been introduced to England by Prince Rupert, the German-born nephew of Charles I of England]

Prince Rupert's drops are easily made by dropping red hot blobs of molten glass into water.
Aben specializes in determining residual stresses in transparent three-dimensional objects, such as Prince Rupert's drops.
In the new study published in Applied Physics Letters, Aben, Chandrasekar, Chaudhri, and their coauthors have investigated the stress distribution in Prince Rupert's drops using a transmission polariscope, which is a type of microscope that measures the birefringence in an axi-symmetrical transparent object, such as a Prince Rupert's drop.
Overall, the researchers believe that the results finally explain the great strength of Prince Rupert's drops.
