Nakamura Miracle Mirror

This is a plastic hemisphere covered with aluminum. The back side functions as a concave mirror and the front as a convex mirror. Reflections of the same object on its two opposite sides are dramatically different.The most outstanding feature of this mirror is the life-like image it projects. A viewer will be surprised to see his or her own image reflected in the concave mirror as if it were another real person.

EXAMPLES OF EXPERIMENTS:

1. A life-like image appears when an object is placed before the concave mirror side.
2. Attach a tiny object like a pin to the edge of a piece of cardboard. Place it upside-down in front of the concave mirror. Even though an image of the object will be projected as though it were a real object, the viewer cannot actually touch it. (See related image)
3. Direct the light from a flashlight onto the real image side and the mirror will reflect a shadow.
4. Expose the concave mirror to sunlight and place a piece of paper at its focal point. The paper will set aflame.
5. The distance between two objects appears greater when reflected in the convex mirror.
6. Fill four-fifths of the concave mirror with water. When an object is placed before the mirror, it appears as if the object is rising up out of the water.

NOTE:
Do not place the concave mirror directly underneath sunlight; the mirror can focus the sunlight, resulting in the risk of fire. Handle the mirror with care as it is covered with aluminum.
