How to Change the Color of Carnations


There are all kinds of experiments you can do with kids to show them the wonders of the world and how things work. Changing the natural color of carnations is a dramatic and simple one that most kid enjoy. This one is so simple that kids can do the experiment with little to no assistance from an adult. Have the children watch as the blooms change color, and have them time it. You can also color flowers for a special occasion or to celebrate a specific holiday.

Step 1

Trim a small amount of the end of the carnation stems. Cut the stems at an angle, using scissors or a knife.

Step 2

Add water to a container that is tall enough to hold the flowers. You don't have to fill the container with water. Just add 1 to 1 1/2 cups of water.

Step 3

Add at least 20 to 30 drops of food coloring to the water. Use whichever color you are trying to achieve. Mix colors for various shades. The carnations will soak up the colored water through their stems and put the color into the petals. This will change the color of the petals.

Tips and Warnings

  • If kids are small, do the cutting for them to prevent injuries.
