I know that popcorn needs moisture content to pop. I had heard that it should not be refrigerated but kept in a tightly closed jar. I guessed the correct answer, maybe because I'm the only one who eats popcorn in my house. I pop it in a Whirly Pop on the stove top in a bit of canola oil. Sometimes a big bowl of popcorn, along with some soup, makes a meal.

I wonder if the research team also got to watch movies as they worked?
