Red or blue food coloring.

the knife)
-
A stick of fresh celery with the leaves still on it

Be very careful,
do not use the knife ( get your
parents or teacher to do this) and cut off the bottom of the celery.

Put the celery in the glass filled with colored water.
-
Let the celery stalk sit there for at least three or
four hours; you can even leave it overnight.
-
When the time has passed, take the celery stalk out of
the water.
-
Use the knife (remember to get help from your parents
or teacher) and cut a slice off the bottom of the stalk.
-
Do this several times.
