Did your child ever ask you why you were watering your plants or how flowers could drink if they don’t have a mouth? We have a simple experiment that you can make at home to demonstrate them how water moves through plants and flower roots all the way to their petals.

What’s needed:

  • 5 narrow glasses or clear test tubes
  • 5 White Flower Stems (ex: White Chrysanthemum, White Rose, White Carnation, White Daisies,…)
  • Water
  • 4 different colors of Chefmaster Liqua-Gel® food coloring.



  1. Add 4 to 5 drops of food coloring in 4 of the 5 tubes. 1 color per tube. 
    • If using tall glasses or cups, you will need more food coloring in order to reach a deep color. 
  1. Fill each test tube or glass about 2/3 to 3/4  full with water. You should have one tube without any food coloring, and 4 tubes with a different color of colored water.
  2. Cut one to 1 ½ inch of the stem of each flower and remove the leaves that are near the bottom to keep them from sitting in the water.
  3. Place one Flower Bud in each of the test tube of glass.
  4. Over the next 72-hours your child will be able to see how the color of the petals are slowly changing in each tube, but the tube left without food coloring, as the flower “drinks”.


Adult supervision recommended.
