There is something magical about hoarfrost. Yes, it is just frost. But the way that it resembles ferns, feathers, leaves, or any number of other natural objects, makes it seem otherworldly. It is impossible not to be instantly drawn to its fantastically delicate branches, which instantaneously crumble at the touch of curious little fingers, making them seem almost as if they vanish by magic.

Some things to know about hoarfrost:
– Hoarfrost is a feathery, leafy type of frost that forms on objects exposed to open air.
– Like other types of frost, hoarfrost is made up of ice crystals.
– It is formed when the frost point in the air is reached and water vapor condenses into ice.
– Cold temps are not enough to form hoarfrost; the air must also be sufficiently saturated with water vapor.
– Hoarfrost often occurs in areas when there is open water, which provides ample water vapor for the frost to form.
