Once again, small ball-shaped pieces of debris have washed up along the coast of Sydney, Australia, forcing the closure of nine beaches in the area while experts try to figure out what it is and what to do next. where they come from.
The gray and white balls, most the size of marbles, appear months after mysterious black balls washed ashore, causing eight beaches to close in October. When authorities tested these bullets, they determined that they were likely the result of a sewage spill.
Now Northern Beaches Mayor Sue Heins says the last balls “could be anything.”
“We don’t know at the moment what it is and that makes the situation even more worrying,” she told the Guardian.

Scientists said they resembled blobs of fat, oil and grease – often called fatbergs – which commonly form in sewage systems from human-generated waste and can form when substances accumulate and stick to each other.
The EPA advised the public not to handle debris balls and to report them when they are found.
