"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."
