Magic mirrors kept in an open room are another attraction of the National Bal Bhavan. Laughing mirrors comprise big concave and convex mirrors arranged in a special manner to reflect funny, distorted images of anyone entering the room. Children find these very amusing and funny. Although these mirrors have been kept for providing fun and evoke laughter, they have an educative value too for the children, who out of inquisitiveness try to find out the factors governing this funny phenomenon. Thus, these help in fostering a scientific temperament among children.
