The show was about to start with the kind of problem one could only find at a Bill Nye event: All the liquid nitrogen had evaporated overnight. It was one of those tiny things -- somebody had forgotten to put a cover back in place from the previous show, and overnight it had all burned off. Nick, Nye's producer, put it pretty simply. "We've got a problem."
