It is a kit that can observe the path of light by reflection of a mirror. The main body has a jabara structure with 2 mirrors, so you can experiment with reflection by changing the angle of bending of the main body or the position where you put the mirror.
The figure drawn in the mirror at both ends is reflected in the castle wall in the center illustration, creating an expanse and depth.
