Ever wonder what happens when a surfer's balls/boobs freeze off? Evidently they wash up on shore en mass. These odd natural formations seem to be cause by a mix of wind, temperature, wave action and snowfall. The phenomenon has occurred in several places around Lake Michigan. Swedes recently found very large ice balls washed up on their shore too.
