2. Mix 10 or more drops of food coloring into the water.
3. Leave the flower overnight, and you'll see the petals change colors. If you leave the flower in the colored water longer, more color will fill the petals.
The food coloring travels up through the stem by capillary action and leaks into the flower's petals. If you look closely at the petals you can see the path that the food color and water travel.
I guess that proves the saying "You are what you eat!"
