hey are so very interesting. Icicles look like they have concentric rings, but are formed by single drops of melted water that refreeze as it gets to the tip. The wind and temperature influence their shape. Don’t they look like limestone stalactites, the ones you find in caves? They have a screw shaped design. Quite pretty and very organic. One icicle at the side of the house is quite long and needs to grow only about 3 feet before it becomes an ice column.
Maybe we should call them winter carrots because of the resemblance. The kids want to eat them.
