How to Create Color Changing Flowers

Have you ever wanted to change the color of your favorite flower? Follow along with this video from ABC11 Science Club to discover how!

How does this experiment work?

Water evaporates through openings (call stomata) in petals and leaves, in a process called transpiration. The transpiration rate varies by a number of factors, such as the amount of sunlight and the number of stomata on the plant. As the water evaporates from the leaves and petals, the stem drinks up more water through tubes called Xylem. In the case of this experiment, the Xylem is pushing dyed water into the dehydrated petals on the plant, causing them to change color.
