Rainbow Celery Color Science Experiment
In this fun and easy color science experiment for kids, we’re going to make rainbow colored celery.
Materials:
- Water
- Jars
- Food coloring
- Celery
Instructions:
- Place the jars out in a nice organized row in a place where the will not be disturbed for a couple days.

How it Works:
The celery uses capillary action to pull water up from the soil and into the plant. In this experiment, the food coloring attaches to the water molecules and travels up into the celery stalk. Xylems are the small tubes in the celery that carry the water up into the celery.
