Bizarre ice eggs cover a 100ft beach in Finland during a rare weather phenomenon. It cover the entire Scandinavian range on the island of Hailuoto in the Gulf of Bothnia. This only occurs about once a year under the right conditions. The air temperature should be just below freezing while the water temperature should also be near freezing.
A shallow, gently sloping sandy area with calm waves and possibly a light swell is the perfect setting for ice eggs to form. moves along the range, back and forth. A small ball surface gets wet, freezes, and gets bigger and bigger as it rolls back and forth. Fall is a great time to see the phenomenon because this is when ice begins to form on the surface of the water, creating a form of slush when moved by the waves.
