Frozen Fog and Frost Prisms

Frost is dew that freezes in the air and then falls. Unlike snow, we do not see it falling. Frost happens when the temperature is above freezing, because it freezes above the ground and then falls. Snow happens when water crystallizes out of the air, and snowflakes were never water drops, unlike sleet or hail. Air at different temperatures can hold different amounts of water, so that when warm air cools, it often rains, as less water can be held in the air in solution.

Clouds must be frozen fog, even on summer days, because they look the same in the winter as in the summer. clouds that are not frozen must be the dark clouds. But we have seen white fog. So why do the clouds look the same whether they are frozen or not?

Yesterday, I took a magnifying glass to look at the sun coming through the frost on the window in prisms of light. I want to get a picture of this, and of the sun coming through the frost on the head of a thistle, and all the sparkles in the field.

Now I want to make a magnifying glass out of water to melt the ice. I have a black Hibachi lid to melt water for the birds and squirrels, so I tried to make a parabola shaped piece of ice. The water was too cloudy, so I’ll try again with snow water. Snow water is pure, unless it picks up stuff from the air on the way down. Drifts out in the open are the most free of pollen and seeds.
