We put celery in red water and a white flower in blue water. The leaves of the celery turned red. The petals of the white flower turned blue. The stems turned blue too. The water travelled up the stem to all parts of the plant.
After six days the leaves of the celery were really red but the stem was still green. The petals of the flower had turned blue all over. The stem and the leaves were a bluish colour too.
The water level in the two vases was lower because the plants drank up the water.
