HOW TO MAKE A RAINBOW ROSE: Obtain a perfect white rose with 8-9 inches stem. Cut the end of the stem into 4 equal parts and up 6 inches. Dip the 4 stems ends into 4 cups of food coloring & wait for 24 hours. I suggest these color combinations: red-blue-green-yellow... violet-red-blue-yellow... or yellow-purple-grey-blue.

Cool science experiment for kids! Rainbow Roses Get white of cream colored long stem roses. (Carnations work well too).
