My girls love science. I love bargains. We all love flowers. How could these three be related? Post-Valentine's Day science experiment! We happened to be shopping the day after Valentine's Day and popped into a store that had their bouquets marked down 50%. Having always wanted to try to color flowers with food coloring, we purchased a mostly-white arrangement. Each of the girls chose two colors and two flowers for each color. We placed the flowers in cups of water and food coloring. The results were varied, but overall, we found that the blue was best-absorbed and the carnations absorbed better than the other flowers. Several of our flowers showed color on one side but not the other. We plan to try this again with fresher flowers and split the stems so one flower absorbs two colors.
