Hoarfrost...

Frost is to dew as snowflakes are to raindrops.

Thank you so much for sending my last soap bubble into the spotlight! Appreciate the responses and I'm glad that I clarified what is was. (Note to self: don't assume that people will know or have seen everything...)

By this morning things had warmed up enough...into the 20's, to make growing those wonderful patterns on the bubbles next to impossible BUT there was hoarfrost which I love. This is a double of hoarfrost at my lake...
