Giant South Dakota hailstone breaks US record
A hailstone weighing almost a kilo that fell in the state of South Dakota has been confirmed as the largest ever recovered in the USA.
According to the National Weather Service, the hailstone that landed in the town of Vivian eclipsed previous record-setters in Nebraska in 2003 and Kansas in 1970.
