Hails are formed in the updraft region of the thunderstorm. the size of hail depends upon the intensity of updraft in the storm. Greater the intensity of updraft larger the size of hail. When the updraft is weakened hail under gravity fall to the earth surface.
We can easily notice hail rings in sliced hail. These rings nothing but alternate rings of white. the White rings( soft ice) is produced by the supercooled water and ice crystal coming in contact with hailstone that is below freezing point temperature on the surface while the clearer rings are produced from water that is above freezing point.
It's the only one that makes sense because there were sets, there were costumes, and I don't think there were too many camera angles because that doesn't make sense either.
