In this section we will build a toy called the Polariscope. As you can see from the above photograph, the Polariscope creates patterns of beautiful colors, somewhat like a kaleidoscope, but by an entirely different mechanism.
In fact, the Polariscope is made mostly of transparent plastic, and none of the fascinating colors are visible in any of the parts out of which it is made. The colors only appear when the toy is finally assembled, and you look through it.
Like a kaleidoscope, when you shake the Polariscope you get a new pattern, and new colors, and the view is never the same twice.
