View options
  1. Tiny water droplets scatter light
  2. Gravity is removed from air
  3. Water vapour creates black colour

Hard · Level 89 · frost,open field,radiational cooling
View options
  1. Open field can have stronger radiational cooling at night
  2. Open fields have no air
  3. Open field stops the Sun
