Melissa and Jam dive into a fun and educational holiday-themed activity using poinsettia plants. They explore the chemistry behind these festive plants, specifically focusing on anthocyanins, which are pigments that give the leaves their red color and act as pH indicators. The episode includes a hands-on experiment that listeners can try at home to visualize how different household items can change the color of poinsettia leaves. Perfect for a holiday break activity that educates and entertains both kids and adults.
