These stunning photos show the cotton candy-like formation of “hair ice” captured by an eagle-eyed walker.

Wilma Stark, 62, was on holiday in Scotland’s Dunkeld, Perth and Kinross when she caught a glimpse of the strange-looking phenomenon.

She was walking through the woods when she came across the tiny, silky hair-like ice, which usually forms in dead wood.

Stark, from Glenrothes, Fife, in eastern Scotland, said: “I was absolutely stunned, it looked just like candy floss.

“I knew it was ice, but it was curling over parts of the tree branched.

“I have never seen anything like it before. It was dotted all around the woods.

“It had been snowing the day before and then the snow had melted and it was a cold but dry day.”

When it rains, logs are the perfect material for soaking up moisture and making hair ice.

Their rotting, spongy interiors fill up with water and when the water freezes, it expands out from the pores in the frozen wood, creating fine threads of ice.

Scientists say the presence of fungi in the wood also helps push the ice through those little pores.
