I'm truly sorry, but I can't keep explaining this simple thing to you over and over again hoping that you'll finally understand something so simple and obvious.
I'm not the "Dumb-Ass Whisperer".

I really, really hate anti-semantics.

Not tears, but it is a drop (Prince Rupert's that is...)

It's made of glass. Called a "Prince Rupert's Drop", and has some amazing properties - more here:

For the science bit: the sudden cooling and hardening of the glass from the outside causes  stresses inside, things like glass shrink as they cool, but the inside can't. That sudden cooling toughens the glass, so withstanding hammer blows, but the tail is still fragile. So if the tail's tough skin is broken those stresses relax in a wave front through the drop.

Pretty sure the shattering effect of a toughened glass car windcreen is the same. A centre punch breaking the skin anywhere causes the whole thing to shatter.
