Make the most of the post-Valentine's day flower sales with this fun experiment.
What's Going On?
Your flowers are "drinking" water. The water that the flowers are placed in travels up the stem and into the petals through a process known as capillary action. Tissue inside the stem, called xylem, carry water up to the rest of the flower. Since our water was colored, the water carried to the petals caused the flower to change colors.
