YOU WILL NEED
Wide-mouthed, smooth, circular glass jar or
large plain drinking glass filled with water
Small mirror
Flashlight
HERE'S HOW
1. Place the mirror inside the water-filled jar. Tilt the
mirror slightly upward.
2. In a very dark room with white walls, shine the
flashlight onto the mirror. A rainbow appears! (Hint: If
no rainbow appears at first, just change the angle of
light from the flashlight or change the angle of the
mirror.)
WHY?
The mirror reflects light that passes back through the
water, traveling at an angle. The water refracts, or
bends, the light. As light bends, it separates into the
colors of the rainbow—red, orange, yellow, green, blue,
and violet.
