DESCRIPTION
- Prince Rupert's Drops are drops
of
glass that
were cooled quickly after formation. The bulbous part
can be hit
with a hammer
without damage, but it will shatter if its tip is broken off.
The internal stresses
are apparent when viewed through crossed polarizers, and show up
nicely
using the document camera and video projector:

showing a drop exploding in slow motion.
