Experimenting with Celery and Food Coloring

We had to make “orange” play dough for Mason’s homework assignment. While the play dough was cooling, Mason decided he was more interested in making other colors using the food coloring. A lot of green and a few drops of blue made…well, green. In a quest to dye objects, I quickly turned him onto an experiment with celery I remembered reading in my Gadgetology book.

What you need: Celery stalk (that still has leaves), water, a few drops of food dye.
Put the celery stalk in a cup of colored water. Wait a few hours. What do you think will happen?
