Primary of A Cube
Primary of a cube is a fun way to play with mirrors. The cube has two 90degree right angles cut into each of its sides. The inside of this cut out is covered with mirrors. The visitor takes a piece of plastic tubing, places inside the cube, and the reflection from the sides looks like a complete cube. The rod and its mirror images can be seen to make other structures also.
