Lauren Godfrey, a freshman, studied the effect of moisture on popcorn volume. “I like popcorn and I wanted to find out what kind of environment would make the most volume,” she said. “So I put the same amount of popcorn in a jar, with and without water, and also on a dry paper towel. I let it sit for five days and flipped the jars over to move the water around. Then I popped it all.” Her hypothesis was that the popcorn in the jar filled with water would yield the most popcorn because, said Godfrey, “Popcorn pops because of the moisture inside it.” But as things turned out, the two dry samples of popcorn popped just fine; however, the wet popcorn didn’t pop, at all.
