Another popular theory - one that experts dismiss along with the others proposed by townsfolk - is that fish could have triggered the explosion of one of several World War II German bombs believed to have been thrown into the pond by an old woman after the war.
"She herself died when one of the bombs exploded in her arms," Cemal Hasan said as he stood on the edge of the "abyss."
Another spooky explanation: The owner of the pond took it with him when he died about a month ago.
"Only days before Hasan passed away he said: 'I'll take everything with me when I die.' And that's what he did," Motanic said. "His daughter saw him walk on the lake the night he died."
Husein Nanic said it could be a sign that the end is nigh: "All sort of miracles happen before the doomsday," he said.
