Question

business used for the construction of kaleidoscope

Answer 1

A kaleidoscope is an optical instrument with two or more reflecting surfaces inclined to each other in an angle, so that one or more (parts of) objects on one end of the mirrors are seen as a regular symmetrical pattern when viewed from the other end, due to repeated reflection. The reflectors (or mirrors) are usually enclosed in a tube, often containing on one end a cell with loose, colored pieces of glass or other transparent (and/or opaque) materials to be reflected into the viewed pattern. Rotation of the cell causes motion of the materials, resulting in an ever-changing viewed pattern.

Answer 2

You should use three long rectangular pieces of mirror glass make a triangular shaped tunnel like structure using glass pieces and cover it with paper and cover both the sides of the kaleidoscope and fill it with some small pieces of bangles and make a hole from one side of the kaleidoscope
