I've got a purely hypothetical question:
ISTR that at one time, freezing locks with Freon was a popular way to
break them. The theory being that you freeze the lock mechanism or
shackle until it becomes brittle, then use a hardened hammer to smash it.
Now I'm being told that's an urban myth.
I come here seeking expertise on frozen metal - is it practical / possible
to freeze steel to where it becomes brittle using a can of Freon? The
technique was to use Freon under pressure, then "spray" it on the lock.
The Freon cools as it expands, freezing the metal.
