Change a White Flower to Any Color

To keep flowers fresh, we put them in water, in a vase. The flowers drink the water and that keeps them looking nice, longer. Well, what would happen if you gave the flowers colored water to drink? Let's try it.

Materials Needed
  • Tap water
  • Cup or bottle
  • Food coloring
  • White flower
  1. Fill a glass or bottle 3/4 full with tap water.

  2. Stir in a few drops of food coloring.

  3. Take a fresh flower, (white carnations work well) and clip the end off of the stem.

  4. Place the flower in the water.

  5. After a few hours, or overnight, the flower will begin to change to the color of the water.

The flower drank the colored water and as the water traveled up the stem and into the petals, it carried the food coloring with it. As the food coloring reached the petals, they take on the color of the water.

Incidentally, this is similar to why flamingos are pink. Flamingos eat a lot of shrimp and shellfish and they absorb the pink and red colors into their feathers, making them pink.
