A kaleidoscope is an optical instrument consisting of two or more reflecting surfaces. These surfaces are tilted towards each other at a certain angle to obtain symmetrical patterns when viewed from the other end. The tube with reflecting surfaces consists of coloured pieces of glass. By rotating the tube, symmetrical images are created.
The word kaleidoscope is derived from the Ancient Greek word called “kalos” meaning “beautiful beauty”, “eidos” meaning “that which is seen” and “skopeo” meaning “to look”. David Brewster, a Scottish inventor, invented kaleidoscope on July 10, 1817.
