Kaleidoscope is a device based on multiple reflections. It consists of three long and narrow stripes of mirrors inclined at an angle of 60⁰ to one another forming a prism. This prism is fitted in a cylindrical tube. One end of this tube is closed by a cardboard disc having a hole at its centre. To the other end touching the mirrors a plane glass plate is fixed on which coloured pieces of glass are placed. This end of the tube is closed by a round glass plate. The Kaleidoscope is ready. When we see through the hole, we can see different patterns. An interesting feature of kaleidoscope is that we will not see any pattern again.
