just an FYI, there's a restaurant in LA (don't remember the name) that makes fresh alcoholic otterpops right in front of you with a pitcher of liquid nitrogen. so that ship sailed long ago i'm afraid =D

Normal U-Locks with accessible Key holes are way to easy to break. Just spray lots of liquid air into the keyhole - this freezes the lock mechanism and one-two hit with a hammer and it falls apart instantly.
(some people also use liquid Nitrogen)

This design protects against that.

Hey, remember that girl who had to have her stomach removed after drinking liquid nitrogen cocktails?

Cold would make a steel frame contract (a little) and make it more brittle / less malleable. But, it'd have to be *extremely* cold (like, liquid Nitrogen cold or beyond) to make it so brittle that it would be more likely to break before bending.

As a result of being merely natural environment cold (in liquid water so not less than 0 C) it probably was a bit more brittle (and therefore harder / less malleable) than the same metal would have been at higher temperatures. Maybe it took a measurable percentage more force to bend in those conditions -- but clearly not enough to prevent it from folding like a paperclip given the massive force on it.

Possible that I'm off on some or all of that, been a long time since Engineering Physics at Uni.
