Kaleidoscopes work on the principle of multiple reflections. The mirrors reflect the images of objects inside, creating a symmetrical pattern. When you look at your reflection in one mirror, you see light that has come from your face and bounced off the mirror.

This article is the first published element of a broader research project that discusses the changing meanings attached to the kaleidoscope during the past two hundred years.
