The kaleidoscope is a toy containing small, brightly-colored tumbling objects, and a set of mirrors which reflect the view of the tumbling objects into repeating, symmetric patterns. The tumbling objects — typically coloured beads or pebbles — are enclosed in a transparent or translucent chamber mounted at one end of a tube; the viewer looks in the other end of the tube. Mounted lengthways along the inside of the tube are either two or three striplike mirrors which combine and form the image.
