Changeable Kaleidoscope with an antique world map motif surrounds the body of the tube. Each of the four rotating ends features a different effect: hearts and gem findings, stained glass with flowers, a floating liquid rainbow and a teleidoscope lens. The kaleidoscope was invented by Sir David Brewster about 1816 and patented in 1817. Sold usually as a toy, the kaleidoscope also has value for the pattern designer. The kaleidoscope is an optical device consisting of mirrors that reflect images of bits of colored glass in a symmetrical geometric design through a viewer. The design may be changed endlessly by rotating the section containing the loose fragments. The name is derived from the Greek words kalos (“beautiful”), eïdos (“form”), and skopeïn (“to view”). Materials: Cardboard, Plastic Measurements: Kaleidoscope: 8" Long Rotating Ends: 2" Long In excellent never been used condition in original box. See pictures for detail. Pet free/smoke free home.
