The Colored Carnation Experiment

As part of a Girl Scouts project my 11 year old setup a science experiment to see if she could turn white carnations into colored carnations.  The idea is very simple.  Take white carnations and split the stems in half very carefully with a knife.  Once split, place each end of the stem in a different glass of water, side by side.  Put food coloring (different colors) in each glass as shown below.

This image was taken minutes after putting the stems in colored water so the flowers are still white.  They are expected to slowly change color over a period of three to four days so we are now in waiting mode.  In a few days I'll post on image to show how they changed...or if they changed.  I assume they'll change based on what others have said, but we shall see what our experiment shows.
