FocalFrenzy, Thanks

Especially for opening the challenge. Great idea and learning experience.

I think the frozen dinner has potential. The day I used it, the Sun also came out and the crystals were nearer to the sleet you described.

Today, using a black plastic bag wrapped tightly around a discarded furnace filter, the flakes were more individual. The plastic was apparently too thin to hold heat, but slick enough so that, as flakes began to pile up, a sharp rap on the sidewalk cleared the field. Still handholding these.

Now comes the work: setting up a tripod for better sharpness, and a collection point easily (and quickly) placed at the right distance from the lens.
