Talk about huge: Last week, the largest hailstone ever recovered in the United States plummeted down to Vivian, South Dakota, the National Weather Service announced on Friday. Weighing in at nearly two pounds, the chunk is eight inches in diameter and 18.625 inches in circumference. Leslie Scott, the farmer who found it, claimed even bigger chunks fell down on the rural town. “I just got lucky, I guess,” he told The Daily Republic. Originally three inches bigger, Scott said the hailstone “shrunk up a lot” in the freezer during the six hours that the town’s power was out. Now headed to a federal lab in Boulder, Colorado, scientists will study the chunk to learn more about how hail forms. The world record, a 2.25-pounder, fell on Bangladesh in 1986.
