And below, people have commented:
“Google says: The image shows a natural phenomenon known as hair ice.
Hair ice is a rare form of ice that grows on dead wood in specific cold and humid conditions.
It forms into fine, silky, hair-like strands.
A specific type of fungus within the rotting wood is responsible for its formation, pushing out moisture that freezes upon contact with the cold air.
The delicate strands can grow for hours, resembling tufts of white hair.”
“I commented a few pics of that same thing just on some old stalks of weeds that my ice crystals are on”
“Looks like a tree branch that’s held onto some hair. Yet another inanimate object that’s accomplished more than my ex ever will.”
…What do you think this is???
