A little science...This would fascinate kids. Rainbow roses, you can do this by splitting the stems into strands and placing each one in food colouring the roses draw the liquid colouring into the petals, amazing!
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.
