A video shows the strangely uniformly sized ice balls washing up in the Gulf of Finland in north-western Russia.
Ecologist Ilya Leukhin told local media that oil spills in the water could have created the ice balls but she was not the only one with a possible explanation for the phenomenon.
Yuryi Shahov, who videoed and shared the sight online, said: 'Seems that someone has thrown snowballs into the Gulf.'
Some believe that snow was rolled together by the waves, or that what look like ice balls could in fact be stones covered with ice.












Comment: There is likely an environmental factor behind this, perhaps some sort of electric discharge that zapped them mid-flight. Or there could be stranger explanations:
