What does the celery experiment prove?
The science bit – how plants transport water
The experiment with a stick of celery reveals that this happens through special tubes, called xylems, which take up the food colouring. The process is accelerated by evaporation from the celery leaves and you can make it go even faster by using a hairdryer on the leaves.
Why does a piece of celery sit blue water gradually turn blue?
When water moves into tiny spaces like that, we call it capillary action. In this activity the color in the water moved up into the celery with the water, because the water molecules attached to the coloring and brought it along.
How do you make celery change color?
Fill each jar or drinking glass about halfway full with water. Now add a different colored drop or two of food coloring to each jar. Put one stalk of celery into each jar. Check on your celery every few hours over the next several days and write down your observations.

What property of water allows for the celery to turn colors?
Celery is handy for demonstrating capillary action because it has a lot of xylem tubes in the stalk, making for fast water uptake. You’ll see the pale green leaves take on a reddish and bluish colour because the dissolved food colouring moves with the water through the xylem tubes into the celery stalk and leaves.
What process caused the water to go up to the celery stalk?
Water is able to move up the xylem through a process called capillary action. Capillary action occurs when the forces of cohesion and adhesion combine in such a way that they overcome the downward force of gravity, and cause water to move upward through the thin tubes.
Can you dye celery?
Cut or rip stalks of celery and place them in the cups of colored water. Let the celery sit. Check every few hours with your child to see how the colors change! Keep the celery stalks in water for a few days and see how the leaves change color.
