Effect:
The magician presents both sides of a big black silk with white polka-dots. He shakes the silk and the polka-dots fly away. The silk turns entirely black on both sides! Then the magician tosses some polka-dot's into the silk. Magically, the white polka-dots return to the silk, on both sides!
