Elementary School's scientific teaching aids to university, because it can make a variety of, various shapes and colors. After reading the kaleidoscope we are prepared, the teachers must ask the teachers to make their own kaleida. Fighting into a square kaleidoscope. Although it is simple to say, it is actually difficult to do it after doing it. Especially when the 6 -piece lenses are put up, these six lenses are actually fixed only with tape, so if you accidentally stick to it, you will stick to it. Crooked, after the kaleidoscope is over, the experiment of polarizer is done. This experiment is mainly to clamp the transparent tablet of the tape in the middle of the polarizer and then see how the effect is. Normally This depends on the tape's post.
