How long does it take the celery to absorb food coloring?
It depends on how much food coloring you are trying to absorb,
and how big the celery is. If you have a small stick of celery and
a lot of food coloring, it will most likely take about a week or so
for the celery to completely absorb the food coloring. When the
color of the water and the color of the celery switch places, it is
fully absorbed. I will be doing this experiment myself to see how
long in days, minutes, and seconds it takes, but if you have any
more questions, try it!
