On June 16, 1882 hail broke windows in the photo studio of Samuel ROOT. Gathering some of the hail, he made a daguerrotype of them and then another so that a comparison could be made with common eggs. Photo courtesy: https://www.facebook.com/groups/45737582684/

HAIL. Hail is a form of solid precipitation consisting of balls or irregular lumps of ice, that are individually called hail stones. Hail stones measure between 5 millimeters (0.20 in) and 150 millimeters (5.9 in) in diameter, with the larger stones coming from severe thunderstorms.

On August 20, 1994 an unusually powerful storm brought baseball-sized hailstones to Dubuque causing more than $10 million in damage. There were more than 15,000 insurance claims.
