Whoa. This is a Prince Rupert's Drop. It's a piece of glass that has a
long snaky tail and a bulb at one end. What's so interesting about a glass tadpole? Well, I'll show you. And remember, this is just glass. (hammering glass) Oh, Prince Rubert's Drops are very strong,
almost as strong as steel. (hammering glass) It's all in how they're made. Molten glass is dropped into cold water. What happens is the outer part of the drop
cools off first, leaving the inner part still hot. When the inner part
eventually cools, it contracts, pulling everything in tighter
and tighter, keeping it under a lot of tension, and because it's round, the force you put
on it is distributed all the way around, just like the force is distributed on an arched
bridge, until you get to the tail. Just the tiniest break in the tail, and... (snapping glass) It explodes. All that energy is released in a chain reaction. Why it's so strong you can hammer on one end, but explodes when you break the other, puzzled scientis
ts for centuries. But now we know it's all in how it's made.
