In November 2016, something funny began to happen on the beaches of northwest Siberia. Over a span of two weeks, thousands upon thousands of giant snowballs washed up on 11 miles (18 kilometers) of the Gulf of Ob's shoreline. Some were as small as tennis balls, others were nearly 3 feet (1 meter) across, and most appeared to be surprisingly exact spheres. Strange as this phenomenon was, it wasn't the first time it happened: online videos show it happening in the U.S.'s Lake Michigan in 2010 and 2015, and another 2015 video captured footage of the ice balls floating in a lake in Maine.
