Infinity Mirror consists of two mirrors facing each other. The image on each mirror is reflected repeatedly off each other into infinity. The observer looks into a hole on the first mirror to see the reflections. A switch turns on small lights bordering one of the mirrors to enhance the effect of infinite reflections and demonstrate how the lights get dimmer as it is progressively absorbed by the mirror through repeated reflections.

Infinity Mirror is available in the "I AM a Scientist" travelling exhibit package.
