Here are a few pictures of the hail I collected. Keep in mind, this is after they had a chance to melt for about 20 minutes outside, and shrink a bit after hours in a Sub-Zero freezer. In the pictures, its hard to tell the actual depth of the hail...this angle is the only one the hail would stay without rolling around. This thing was huge, about 6 cm in diamter after melting/freezing. Amazing.
