Ice-cream eggs
Ice eggs are a rare natural phenomenon in winter . These are pieces of ice the size and shape of chicken eggs to the size of footballs that form naturally in water.
According to media reports, the phenomenon was observed in 2019 on the Baltic Sea on the beach in Marjaniemi; it is located on the island of Hailuoto on the Finnish west coast. A similar ice phenomenon was detected in 2016 on the coast near Nyda in northwestern Siberia with soccer-sized ice balls. Ice eggs have also been spotted on Lake Michigan near Chicago .
The circumstances that lead to the formation of ice eggs have not yet been clearly clarified. According to weather experts, certain meteorological conditions are necessary for formation, such as water and air temperatures around freezing point . In addition, a flat beach and a little wind are necessary. With gentle wave movements, a thin layer of ice accumulates on a pebble or a washed-up piece of wood, which grows evenly.
A British weather expert has a different explanation for the formation of ice eggs. He assumes that these are fragments of larger layers of ice that are ground round by the surf and sand by the sea .
