Question

what is the conclusion ofREFLACTION OF
kaleidoscope?

Answer 1

Following its invention in 1816, the kaleidoscope grew in popularity around western Europe, and the first one to appear in the United States was reported in 1870. It became a favorite toy for children but also an entertainment for adults in parlor games like viewing stereoscopic photographs and playing charades. The most famous kaleidoscopes, other than Brewster's originals, were made by Charles G. Bush of Boston. The Bush kaleidoscope was constructed of a viewing tube of banded black cardboard, a brass wheel to turn the object box, and a wooden stand. It was the objects that made Bush's version unique (and a valuable collectible today). He used 35 objects of various colors and shapes, but some were filled with liquid containing air bubbles. The air bubbles moved through the liquid even when the observer held the object case still. Bush secured the patents for the liquid-filled objects (ampules), for his method of adding and subtracting objects without taking the box completely apart, and for stands and other kaleidoscope accessories.

As a tool for designers, the kaleidoscope produces ranges of colors and patterns used to create rugs, stained glass, jewelry, architectural patterns, wallpaper, woven tapestries, and ideas for painters. The kaleidoscope fell out of popular interest in the early twentieth century, but it revived in the late 1970s when new styles and the collectible character of antique kaleidoscopes fired the curiosity of new generations. Bush's kaleidoscope with the liquid-filled objects sold in 1873 for $2.00; collectors in the early twenty-first century willingly pay over $1,000.
