What are the procedures to put flowers in food coloring?
Answers
Tips
Materials: Light-colored flowers, food coloring, water
Concepts Illustrated: Evaporation, cohesion, xylem, capillary action
Time Required: Few hours to a day
You can use other colors of flowers besides white
1 Trim the stems of your flowers so they aren't excessively long.
2 Make a slanted cut at the base of the stem under water. The cut is slanted so that the stem won't sit flat on the bottom of the container. A flat cut can prevent the flower from taking in water.
3 Make the cut underwater to prevent air bubbles from forming in the tiny tubes at base of the stem, which would prevent water/color from being drawn up.
4 Add food coloring to a glass. You're looking at about 20-30 drops of food coloring per half cup of warm water. Warm water will be taken more readily than cold water.
5 Set the damp stem of the flower in the colored water. The petals should become colored after a few hours. It may take as long as 24 hours, however, depending on the flower.
6 You can set the colored flowers in plain water or flower preservative, but they will continue to drink water, changing the pattern of the color over time.
You can slit the stem up the middle and put each side in a different color to get bi-colored flowers. ..
