When you gaze into an ordinary mirror, you see a reflection of yourself and the world around you. A mirror reflects images because its smooth surface repels almost all the photons, or light rays, that strike it. When you look at an infinity mirror, though, you see what looks like a long hallway of mirrors with no end. This illusion happens because the light rays strike one mirror and bounce back to the other repeatedly, creating a never-ending chain of reflections.
Things You'll Need
- Two 1-by-4-inch wooden boards, any length
- Two 12-by-12 or larger glass or acrylic mirror sheets
- Hole saw
- Dovetail saw
- LED light strand -- optional
Use a dovetail saw to cut a 1-inch slit down the length of two 1-by-4-inch wooden boards. These boards will serve as the stands for the mirrors.
Cut a circular hole in the center of each acrylic mirror sheet, using a hole saw. Hardware stores can usually do this for you if you do not have a hole saw. If you are using glass mirrors instead of acrylic sheets, use a knife to scrape some of the silver backing off the center of each mirror.
Slide the mirrors into the slits you cut in the wood boards. Set the mirrors about 6 inches apart with the reflective sides facing each other.
Line one of the mirrors with an LED light strand, if desired, to enhance the infinity illusion.
Look through the hole in one of the mirrors to experience the infinity illusion.
Tips & Warnings
- You can also see the illusion by looking over the corner of one of the mirrors.
- Do not allow children to cut holes in the wood or mirrors without adult supervision.
