Description
Kaleidoscopes operate on the principle of multiple reflection, where several mirrors are attached together. There are three rectangular lengthwise mirrors. Setting the mirrors at a 45 degree angle creates eight duplicate images of the objects, six at 60°, and four at 90°. As the tube is rotated, the tumbling of the colored objects presents the viewer with varying colors and patterns. Any arbitrary pattern of objects shows up as a beautiful symmetrical pattern created by the reflections in the mirrors.
