Why is the colorful Christmas tree toy paper tree blooming
“Christmas tree blossom” utilizes its crystallization principle: when the paper tree is immersed in an aqueous solution of potassium dihydrogen phosphate, the solution diffuses in the paper tree by capillary action, and crystallization occurs as the water evaporates.
The colored pigments are absorbed by the crystals, forming colorful “flowers”.
That is, this water is an aqueous solution of potassium dihydrogen phosphate.
