Future Flowers

"It's 2075 A.D. with plant life having to grow straight up to avoid overcrowding." A stalk of futuristic flowers is shown by the magi. The top three flowers are yellow because of the sun's direct rays. The bottom three are red because they are constantly in the shade. Through a mutual agreement between the flowers, equal time for the sunlight is provided: The magi passes his hand over the stalk and the flowers are seen to alternate yellow, red, yellow, red, etc! Great visual magic!
