AMAZING ICE NEEDLES

In the video, which was posted on YouTube on April 28, passers-by can be seen touching the shards of ice as they pile up on the shore of the lake.

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 centimetres long.
