Advertisement Late last month, a rock weighing around 10.6 ounces (300 grams) pinged onto a driveway belonging to Rob and Cathryn Wilcock, who live in the small town of Winchcombe, UK. “When I heard it drop, I stood up and looked out the window to see what was there. But because it was dark I couldn’t see anything,” Hannah, the daughter of the couple, told the BBC. “It was only the next morning when we went out that we saw it on the drive—a bit like a kind of splatter. And in all honesty, my original thought was—has someone been driving around the Cotswolds lobbing lumps of coal into people’s gardens?”
