I worked at an optics company where I was able to "play" with liquid nitrogen for almost 10 yrs. I too was of the thought that things became fragile and shattered like glass when frozen to those temperatures. Ends up, that most things are pretty resilient. I was actually difficult to get regular items cold enough to cause them to shatter. I even had one of those small oranges submerged for almost 5 minutes. Then took it outside to try and shatter it on the ground. While the outside broke, the inside was still not solid, but rather a mush consistency. Pretty much lost interest in trying to deep freeze things after that. It was still fun to throw up a cup full of liquid nitrogen into the air at flying insects. They tend to die in mid flight. Of course this was all done wearing proper PPE.........
