Detailed explanation-1: -The celery stalk that seemed to have absorbed the most water was the one in blue water. You can easily see the bright blue colors in the leaves.

Detailed explanation-2: -Celery is handy for demonstrating capillary action because it has a lot of xylem tubes in the stalk, making for fast water uptake.

Detailed explanation-3: -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. In nature, the water moving into a plant brings with it nutrients from the soil.

Detailed explanation-4: -Check at intervals depending on availability, you will see slight results after 3 hours, significant results overnight and again at 48 hours. Cut the bottom of the celery and you can see where the water was transported up into the celery stem.
