More art (kelidoscopes)

In art today we are making kaleidoscopes. Here is some history and some general knowledge! In 1648 an experiment was conducted by athanasiu kricher with two mirrors which sparked another experiment by sir David Brewster conducted on light polarization. He forgot about the results but noticed the beautiful reflections . This triggred experiments to find semetricaly perfect conditions. The next step was conducted with colored glass which created the kaleidoscope.
