Take a little time out and have some fun with flowers and food coloring. Have you ever wondered where the water goes after the plant is watered? This experiment shows the water being absorbed through the roots and stems finally reaching the petals. Imagine Blue Red & Green Striped daffodils or carnations.
To start this experiment you just need Water Food Coloring Cups or Small Vases a knife and the flowers. You can use daffodils or white carnations. Place one or more flowers in a container with water. Add food coloring, about 20 drops per cup. If the container is larger it will need more food coloring. The water feeds the flowers and you can watch the petals change color. The edges color first and the veins are last. To prepare the flowers cut the stems at an angle to create a fresh cut. The stems need to be completely in the water for it to work. You can see if one color reaches the petals faster than another color.
A trick you can do called “Split Ends”, take the knife and split the stem straight down the middle and put each half in a different color water. Place your cups close together so the flower can sit in both. Check your progress every few hours. Some flowers take as much as 24 hours for the colored water to reach the petals. The dye does not hurt the flowers and you can see the color change in the stem leaves and petals. The unofficial results say the blue dye travels faster… but try it yourself or with your kids. Coming in second is the red and then the green. You will end up with a variety of colors. Try mixing the colors or adding sugar to the recipe for a different look. Have fun and enjoy!
