Let’s Make Some Magic with Color-Changing Flowers!
Amaze your friends and family with this valuable chemistry lesson!
When you tear into this kit, you may think that we’ve led you astray. Why did we give you normal white carnations? These flowers aren’t magic at all. Not to worry. Although these flowers appear to be ordinary white carnations, we’ll soon have you believing in the science of magic. You’ll be changing seemingly magic-less white flowers into a brilliant pink color activity that your friends and family won’t soon forget, all while teaching them a valuable lesson in chemistry.
How does it work?
Magic Flowers use the properties of the pH indicator phenolphthalein to change color right before your eyes. The magic comes from the phenolphthalein used to coat the flowers. When the phenolphthalein (an acid/base indicator) interacts with ammonia, which is a base, the results are the vivid pink color that appears. Your friends will think that it’s magic until you reveal the science behind it!
What does it teach?
PH is the measure of how acidic or basic a substance is, and in this experiment you are showing how ammonia is a base. Phenolphthalein is a special indicator that is clear when in the presence of an acid (air is slightly acidic).
