A Chinese man inadvertently created a frozen waterfall outside a block of flats - when he left his tap on all winter. Wen Hsu, 58, was the last remaining resident of the building, scheduled for demolition to make way for a new shopping centre in Jilin city, Jilin Province. As winter approached, Hsu was worried the uninsulated water pipes running up through the unused and unheated flats below him would freeze, leaving him without running water. So he simply switched on the tap - and then diverted the warm water to flow down the side of the building. –WO
