Copper Sulfate Roses: Crystal Blossoms from Solution
When crystals grow on roses, ordinary petals turn into dazzling blue blooms. This article introduces the copper sulfate rose experiment and the chemistry of crystal growth.

I am Bowen Zhang, one of the leaders of the chemistry club. Another club leader and I usually take turns preparing experiments, running trial experiments in advance, and explaining and guiding club members during the experiments. I work carefully and attentively, and I have led students in carrying out eye-catching inorganic chemistry experiments such as underwater gardens, ocean heart, and iodine clock reactions. Next semester, I plan to continue strengthening my subject knowledge while also trying some basic organic chemistry experiments in the chemistry club.
