Kaleidoscope Projector

Based on an 1816 device, this working Kaleidoscope Projector is ideal for people who love to make things, science fans, or just anyone who likes a challenge. Build the kaleidoscope based on the diagrams in Gakken's Otona no Kagaku magazine and then dazzle yourself and your family with the amazing patterns and colors you can project onto your walls.

The magazine is in Japanese but contains clear diagrams that allow even non-engineers to get the satisfaction of constructing a working device as sophisticated and fun as this Kaleidoscope Projector.
