The Mr. Gear YouTube channel is doing the liquid nitrogen game over and over. While some objects, like toy trucks and a Rubik's cube, become brittle and shatter, some of the objects are far more entertaining. Eggs become hard boiled (cold boiled?) and turn to dust (except that one that shoots yolk all over). Coke bottles turn into a slush substance that looks a bit like what you can get to drink at a little league game.
Watch one of the destructive videos above and if you need some more, there's another one below.
