This exhibit has a flexible fun-house mirror. In order to change the shape of the mirror, the participant will pull a handle that flexes the mirror.

You can help the participants understand how the change in the shape of the mirror leads to changes in their reflection. Remind them that light travels in straight lines, but changes direction when reflected from a curved surface.

You can point out that optics is strongly related to geometry. When the mirror is concave, light rays from the left and right sides can cross past each other, and end up on the opposite sides, resulting in a reversed image. In a convex mirror, this can never happen.
