Celery experiment

By shelby on January 18th, 2010

For science I did an experiment. I put celery  in a jar and put 30 drops of red dye in the jar with 1 cup of water. I left the celery for 24 hours to see how the celery absorbs water.  It was very cool when I looked at the celery. All of the leaves were red where the veins were. This is one of my favorite experiments.

After 24 hours in the jar with red dye, the celery stalk absorbed the redy dye and the leaves turned red.
