It's been really cold over the last few nights, however, the recent weather has thrown up the necessary conditions to form hoarfrost. Hoarfrost is usually seen as deposits of ice crystals on anything exposed to the free air,. You'll see this on grass, tree branches, leaves and most spectacularly on things like dried flower heads or spiders' webs.
The beautiful manifestations of hoarfrost occur by condensation of water vapour to ice at temperatures below freezing and occurs when air arrives at its frost point by cooling.
This process is quite similar to the way in which dew is formed on delicate objects.
So, now that's ruined the magic of the frosted spider's web for you, it's time to get out into the countryside to see some of the beautiful sights formed from just a bit of frozen water vapour.
