Answer 2

TAKE A CIRCULAR CARDBOARD DISC OF ABOUT 10 CM DIAMETER. DIVIDE THIS DISC INTO SEVEN SEGMENTS. PAINT THE SEVEN RAINBOW COLOURS ON THESE SEGMENTS. MAKE A SMALL HOLE AT THE CENTER OF THE DISC. FIX THE DISC LOOSELY ON THE TIP OF A REFILL OF A BALL PEN. ENSURE THAT THE DISC ROTATES FREELY. ROTATE THE DISC IN THE DAYLIGHT. WHEN THE DISC IS ROTATED FAST, THE COLOURS GET MIXED TOGETHER AND THE DISC APPEARS TO BE WHITISH.
