What happens if you take a giant Koosh ball* and pour liquid nitrogen all over it? Fortunately, a physics lab sponsored by the U.S. Department of Energy (I'm not kidding; it's actually awesome) answers these questions for us:
If you, like me, wondered, "Hey, what's up with them dumping out all that liquid nitrogen at the end?" there's also a video explanation of that! Stick around until 0:53 to see what happens on a smooth surface rather than a carpet:
* = I'm not entirely sure this is a real-deal Koosh ball; it may be a knockoff "puff ball" or some such. Still -- close enough, right?
