- 3 White Carnations
- 3 Bottles of Food Coloring in Assorted Colors
- 3 Clear 16 oz Plastic Cups
- Fill each cup with water half way.
- Add 3 drops of food coloring into each of the cups. Each cup should be a different color.
- Carefully cut the end of each of the flower’s stem.
- Place each stem in a different colored water cup.
- Wait one hour and observe your flowers’ petals.
- Wait one day and observe your flowers’ petals.

How it Works:
The Xylem of the flower works like an elevator and brings the water from the cup all the way up the plant’s stem and into the plant’s petals. When it brings the dyed water up it ends up dying the plant’s petals. The Xylem is what allows the plant to get water from the roots all the way to the petals.
- What happens if you try doing 5 drops of food coloring instead of 3 drops?
- Keep a picture log of your flower. Take a picture each day, and see how many days does it take for your flower’s petals to look the most saturated in color.
- Try using other types of flowers. Do they work as well? Why do you think we suggested using white flowers?
