On the coast of New South Wales in Australia, gray balls of unknown origin have been discovered.

According to The Guardian, the State Protection Department (EPA) quickly cleaned the beaches. It is not known whether the purple blood of an unknown substance is related to those who appear on the Sydney coast in January.
The chemistry professor from the University of New South Wales said that the smell was disgusting. Currently, it is believed that the mysterious balls fell into the water from the sewer. Perhaps the drainage system has failed due to the lack of repair and increased load compared to the platform of population growth.
New balls can be in the water from sewers or removed from the ships.
The Council of the Central Coast has advised not to visit those beaches. The samples of the balls are found are currently being studied.
