“Jack Frost has a decidedly mischievous streak in his character, it seems. For when Robert Baker went outside on Wednesday morning, he found his car had been sprayed with dramatic ice graffiti.”

“It appears the ice artists were out in force. In Oxfordshire, Stuart Dent found similar patterns on his Jaguar. Car windows and paintwork are good heat conductors and water droplets often form in very cold weather. Tiny imperfections such as scratches and dust influence their arrangement, so when they freeze, they form beautiful patterns.”
