experimental procedure

1. Take a piece of white filter paper or white paper with strong water absorption, cut it into petals, and tie the cut flowers into paper flowers with thin wires or fine iron wires. Soak the paper flower in the cobalt chloride solution of about 1 mol/L for a while, take it out and dry it, then soak it in the cobalt chloride solution and dry it for several times until the paper flower turns pink.

2. Light the alcohol lamp and bake the pink paper flowers on the flame (in order to prevent the paper flowers from burning, you can put an asbestos net on the iron shelf and bake through the asbestos net). The pink of the flower gradually turns to blue, and finally becomes sky blue, sunny and rainy in bloom. Hang this flower on the wall, it can forecast the weather.

If you are anxious to know whether this flower will work, you can spray some water mist on the paper flower, and the blue flower will turn pink immediately, and then it will turn blue after baking on the fire.

What is the principle of sunflowers?

At room temperature, seeing blue flowers turn pink shows that the humidity in the air has increased to a certain extent, and anhydrous cobalt chloride has absorbed water and turned into cobalt chloride crystals, which may rain. If you see the flowers change from pink to blue, that is, the cobalt chloride crystal loses water and becomes anhydrous anhydrous cobalt chloride, it means that the air humidity will decrease and it will clear up.
