What is the principle of sunny and rainy flowers
Under normal temperatures, when you see blue flowers turn pink, it means that the humidity in the air has increased to a certain level and there is no water. The cobalt chloride has absorbed water and turned into cobalt chloride crystals, and it may be about to rain. If you see the flowers turn from pink to blue, that is, the cobalt chloride crystals lose water and turn into anhydrous cobalt chloride, it means that the air humidity has decreased and the weather is about to become sunny.
