In this short video (no ad), shards of ice are forming and are literally popping out of a frozen lake in large piles. We are witnessing the natural phenomena of the formation of ice needles. They even make an incredible sound as they form. This is amazing to watch!
Ice needles occur when the temperature of the soil is above 0°C and the surface temperature of the air is below 0°C. The subterranean water is brought to the surface via small capillaries and then freezes as it goes into needle-like columns a few centimeters long.
