Later in the early 1870?s, an American called Charles Bush (1825-1900) improved upon the kaleidoscope and started the kaleidoscope fad. Charles Bush was granted patents in 1873 - 1874 related to improvements in kaleidoscopes, kaleidoscope boxes, objects for kaleidoscopes (US 143,271), and kaleidoscope stands. Bush was the first person to mass manufacturer his "parlor" kaleidoscope in America.
A teleidoscope is exactly the same as a kaleidoscope, except that the teleidoscopes object case is simply a lens. The lens will show whatever you are pointing the scope at around you and the mirrors will reflect that image, which will change as you move the scope around. Sometimes a glass or crystal ball is used as the lens. Teleidoscopes can be either 2 mirror (Mandela) or 3 mirror
