How to Dye Celery

Things you’ll need:

A glass, big enough to hold celery stalks and leaves upright
Food coloring
Water
Fresh celery stalks
Cutting board
Knife




1. Fill a glass of water about half full of water and then add some food coloring to the water. Dark or bright colors show up best.

2. Check the celery every hour. After about an hour, it will start to show some of the food coloring going up the stalk. You can measure how far the color goes up the stalk every hour. In time, most of the celery will be colored.

3. Water is absorbed by a plant. It travels up the stalk and then goes into the leaves. This is an explanation of how water is circulated in plants. You will need to leave some leaves on your celery stalk, as a plant's circulation works by "transpirational pull" — that is, the leaves are breathing.
